This Problem Across All Years
In May 2021 I purchased my Highlander XLE with 5 miles on the odometer. In Feb 2021 dealerships were notified of Toyota Technical Service Bulletin (T-SB-0008-21) dated Feb 2021 was a problem. I have never been notified of the TSB for transmission whine/grinding noise. At approximately 75,000 miles (out-of-warranty) and regular servicing, my vehicle developed a noticeable whine from the transmission. Now at 102,000 miles I am stuck with a transmission replacement ($7500-$9000) looming at sometime in the future. Very disappointed. I have been reprimanded by grandkids that "You drive like a Grandpa" so, I am not hard on my vehicles. My 1993 Chevy S10 had over 388.000 miles when sold. it was solid!. I think Toyota should be forced to do the right thing and cover any cost of replacement and temporary rental. Seems replacements are back ordered for months!

I bought my 2021 Toyota Highlander on 11/17/2025 and approximately one month later, I heard a whining noise when the car accelerates past 25 mph. The whining noise gets progressively louder the more the car accelerates. In addition, when driving over a bump or hump, there is a grinding/creaking noise that occurs. I took my car into the Toyota dealership on 12/29/2025 and the service technicians were able to replicate my issues. They even stated that the issue is caused by a bearing failure inside the transmission. I also purchased an extended warranty but unfortunately the inspector sent by the warranty company wants me to get a transmission fluid exchange because they think that will solve the issue. The entire transmission needs to be replaced.

I have a faulty transmission that is now widely known. 2021 Highlander with the UA80 transmission. Out of warranty and Toyota wants to provide no help even know this is an ongoing issue with so many owners

The transmission has developed a transmission whining noise which Toyota has released a TSB 0008-21. My vehicle has 104,000 miles and is now out of warranty. If this is a known defect on many Toyota vehicle models a transmission replacement should be free if no longer in warranty.

Almost caused high speed accident merging onto toll road! The vehicle is experiencing a severe transmission slippage, shudder, and grinding noise, consistent with TSB-0008-21 (UA80 transmission failure). This defect causes hesitant acceleration and erratic shifting, creating a safety hazard when merging onto highways or crossing intersections. I am concerned the transmission will fail completely while driving, resulting in a sudden loss of motive power and increasing the risk of a crash. Toyota has covered this exact safety defect in 2017–2019 models (CSP ZJC) but has failed to recall the 2021 models despite identical symptoms. First reared it's head as slipping when putting vehicle in reverse, 25k+ ago. Was told by Toyota Certified mechanics it was an operator error. Morphed into larger issue.

To whom it may concern I hope I've chosen the proper avenue for my problem. I purchased and new 2021 Toyota Highlander. I chose Toyota for it reputation of high standards of dependability. However I took the vehicle in at 20,611 miles (9/22/2021) into the dealership for multiple transmission issues. When passing it would kick down into a lower gear and race the motor. There was also chunky shifting and a small whining noise. (service Ref #XXX). The service manager only wrote down the first symptom. Upon doing a computer diagnostic without driving the vehicle the service manager told me to just drive it more that it probably needed more breaking in. The downshifting and chunky shifting did go away for the most part, but the whining persistently got worse. Finally at 115,000 miles it got much worse and I took it back to the dealership. They informed me that the transmission needed replaced at over $9,000. I reached out to Toyota upon finding out there was a in company TSB alert for this very symptom (Case #XXX). Toyota informed me there was nothing they were willing to do since it was out of warranty even though I reported the problem with no resolution when it was in warranty. My wife and I are in our [XXX] and don't have cash like that. we don't feel we should be responsible for the repair, especially when the issue was report properly before the warranty expired. How can you help? Thank you for your attention. [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I brought my 2021 Highlander L in for some regular maintenance and reported that within the last 2 weeks I have been hearing a whining sound when the vehicle is decelerating. I was informed at the end of the day that the transmission is bad and needs to be replaced. My vehicle is just outside of warranty (69k miles). I have always ensured my Highlander got an oil change on time, had all recommended maintenance done at that appropriate time/milage, and brought it in for safety recalls promptly. This vehicle has never been in an accident, and while I have owned it (and according to Carfax when I purchased it) I have always brought it to a Toyota dealership for any and all work. There have never been any warning messages, and even though my vehicle has been into Toyota regularly for oil changes and regular maintenance, I was never notified of any other issues. I also use this vehicle at least once a year for road trips (over 200 miles) and before every trip bring it in to have it checked. I'm being told it'll be about $10K to fix. Based on my research I have discovered this is a problem MANY people with a 2021 Highlander are having, also a class action lawsuit was filed due to transmission issues but only covered Highlanders up to 2020. This seems to be the same issues those vehicles had but I'm being told it's not covered or a recall.

2021 Highlander XLE started making a whining noise when accelerating. Noise stops when you let off the gas. Took it to Toyota who said the transmission needed to be replaced. Although everywhere you look this is apparently a known problem, Toyota has yet to cover it or recall the part making the owners have to pay 9k to replace a transmission.

Slipping and Whining transmission while driving in the Ozark mountains on [xxx]. I didn't feel I had full control of the vehicle. No warnings of any kind. Took the vehicle to Saint Charles Toyota service department on 10/2/25 where a bad transmission diagnosis was confirmed.

Transmission began producing a whine sound at 58k and slipped several times.. A transmission that slips could cause a wreck involving all passengers. Requires replacement. No warning lamps. Show some integrity Toyota and stand behind your products.
There is a known transmission issue with some 2021 Toyota Highlanders, Avalons, and Camrys. Toyota Bulletin T-SB-008-21 from February of 2021 states 'Some 2021 model year Avalon, Highlander, and Camry vehicles equipped with UA80E or UA80F transmissions may exhibit a whine or grind noise from the transmission. This condition may be caused by an issue with the front carrier assembly pinion shafts'. I have a 2021 Highlander with 127,000 miles that started to show this whine noise. Local transmission shop confirms that a new transmission is needed. I am taking it to a local Toyota Dealer next week to confirm. I started a case online with Toyota USA, and since I'm over Warranty, they started that will not assist with reimbursement. My complaint is how came a recall was not done on this? Why did Toyota do nothing and now many of their customers with these vehicles face costly repairs ($7,000 - $12,000)? Toyota should at least reimburse their customers for some of the cost of the repair needed for this, even if out of warranty.

66,564 Miles, Transmission slipped and caused a delay in power, now it has a big high pitched whine and continues to do it. This looks to be a big problem across the board for 2021 Highlanders.

Hearing a whining noise when I step on the gas pedal. The toyota dealership informed me I need a new transmission on a 4 year old vehicle with about 88,000 miles on it. Toyota said because there is no recall, they will not cover the replacement
Winning sound coming from the transmission - upon seeking information online I was able to find a service bulletin from 2021 that addresses the issue - I see a large number of posts online with people having the same issue - the only solution is a transmission replacement - Toyota should be made to do a recall on these vehicles

Noticed 2021 Toyota highlander start whining around 85000 miles. Did some research on the sound and found that Toyota UA80F transmissions have all had the same issue and issued a tsb to their dealerships but not people who purchased the car. Warranty runs out and now you are on the hook for an 10k transmission replacement or risk your car breaking down at any point on the road. Car was inspected today by Toyota to receive the quote to fix at 10400 with no discussion of possible remedies for their defective transmissions. The exact quote would be "that's not our problem, you have to take it up with Toyota office, bud". So now we have a ticking time bomb on the road with the only remedy to pay 10400 to replace a defected transmission that was covered in other recalls by the same company.

Entering the freeway a mile from home the car would not properly excellerate, only reachind 40 mph before exiting the freeway in favor backroads to my appointment. Shaking back and forth while driving, exacerbated when braking and coming to stop, I needed to put the car into neutral to calm down the shaking while waiting for the light to change. I just went through experiencing a brake failure and reporting of that to this Agency and now see another of many defects associated with the 2020-2022 Toyota Highlanders and Siennas Toyota is not addressing through Recalls as they should be, and further frustrated this Agency has or chooses to have no means by which to enforce Toyota's responsibility to the public
at 65,000 miles, the transmission has developed a "whining" sound consistent with TSB T-SB-0008-21.

Transmission in our 2021 Toyota Highlander required a full replacement due to a known part defect (front carrier assembly front pinion shaft). Toyota will not cover any portion of the $8k cost. In looking into the issue, this is very widespread with even our dealership confirming four transmission replacements by customers in a short period of time. The transmission is also back ordered (ours took 3 months), but the dealership has seen up to six months. I am guessing this is do to the high demand.

At 119,000 miles, the UA80F transmission in our 2021 Toyota Highlander XSE started making a whining noise. A dealer confirms the transmission needs to be replaced. After much research, this is apparently a known issue and Toyota will not warranty the repair after the 60,000 mile warranty expires. Estimated repair cost is $11,000.

Complete failure of transmission at approximately 53k miles. No warnings. No lights. Car had just had its 50k miles service appointment. My safety and that of my family was jeopardized when I unknowingly took this car to/from our family vacation out of state- the gears started jumping a few days after we returned, quickly followed by the grinding, whining noises. Come to find out there is a service bulletin that has been out for 4 years! T-SB- 0008-21 issued on February 9, 2021, for select 2021 Highlander models equipped with a UA80E or UA8OF.8-speed automatic transmission. Why wasn't this a recall? How is this not a safety issue? Why wasn't this disclosed by Toyota when I was sold a car with 30k miles on it for $35k miles?

My Highlander is making a whine noise due to the issue described in T-SB-0008-21. I was never made aware that this was a potential issue. My car is making the whine noise, but Toyota Of Capistrano refuses to cover the cost of fixing it because my car has 86,000 miles. I would have taken the car in sooner had I known of this issue.

Started hearing a whining noise when I would accelerate and then my car bucked a couple of times. I brought it into Toyota on 8/07/25 to be checked out and I was told that my transmission would need to be replaced. My car is 4 years old, bought brand new in April of 2021 and have kept up on regular maintenance. In researching this I am finding out that there is a large number of people who are experiencing this same thing with their Highlanders. I have also come to find out that in February of 2021 there was a TSB put out with regards to this same issue. This was 2 months before I even purchased my car. It for some reason does not include every vehicle and only some vehicles are included leaving others with this problem out of luck. I do not understand how that can be. If I have that UA80F transmission in my car and that is what is being named as one of the transmissions that have this problem then why is that certain vehicles are not being taken care of and why is Toyota not issuing a recall? My warranty has expired so I am being expected to pay out of pocket $8,000 (not including labor) and on top of that they do not even have the parts as they are on back order. We have to hold Toyota responsible for this.

Transmission failed and makes whining noise
Transmission failed and makes whining noise
Vehicle starts to produce humming and whining sounds as speed picks up from underneath the vehicle, likely from the transmission/final drive gear area. This problem is consistent and persistent. The whining noise stops when the throttle is released and will resume as throttle is engaged. More reported cases of transmission failure, sudden lost of propulsion and grinding noise are found on public forums. Toyota issued a service bulletin about this problem. Toyota issued extended warranty to prior model years from 2016 to 2017 of the same issue. This will affects millions of Toyota sold with the UA80, UA80E and UA80F transmissions in the US.

whine when accelerating. toyota has released a tsb 0008-21 indicating to replace transmission due to incorrect installation of a retaining clip on a nut securing differential in place.

When our vehicle reached about 70,500 miles (10,000 miles past when the powertrain warranty expired), the vehicle started making high-pitched whining noises when the gas pedal was depressed. We brought it to the Toyota dealership and were advised that the vehicle's transmission needed to be replaced and were quoted $9,700. This is for a vehicle that was only 4 years old!! We do not feel that this is a repair/issue that a consumer must bear the cost of! When we shared this with the Toyota technician, he stated that unfortunately, the Highlander's powertrain warranty expired at 60,000 miles. We understand that Toyota was aware of this issue and this should have been escalated as a NHTSA recall where the manufacturer should be responsible for the cost of repair and/or replacement, not the consumer. Please assist us with obtaining a satisfactory resolution with this.

Our vehicle has 72k miles at normal use- no towing or off roading. Due to a whining noise we took in the vehicle at a Toyota dealer and after a $200 diagnostic fee concluded we need a new transmission priced at $10,800. There was no explanation/diagnosis summary- just we need a new transmission.

I purchased a 2021 Toyota Highlander in June of 2024 with about 45k miles. The transmission completely failed at 67k miles, when I brought it in to have checked in April of 2024. This is not covered under warranty and is costing 7-8k in repairs and over 3k in rental vehicles. I'm told the transmissions are on back order for 3-6 months. No lights went off in the car warning me of this. I smelled burning fumes on and off and reported it to the service dept around 59k (January 2024) miles. I did feel a jump at times, but didn't report that. After my routine oil change at the end of March of 2025, I heard a whining noise only when accelerating and would immediately stop when I released my foot. Two Toyota Service departments diagnosed my car with a failed transmission. I haven't been able to drive my car for 2 months now. My family's safety has been at risk while this issue with this transmission failure has been known and not reported to the consumers prior to my purchase in June of 2024. Potential consequences to a failed transmission while driving are as follows: -Sudden Stop or Coast to a Stop: The car might stop moving entirely, especially if internal components seize or it just loses power and I coast to a stop. -No Response to Acceleration -Pressing the gas has no effect, which is dangerous if I'd be in traffic or on a highway. -Locked-Up Transmission -Rare but possible, especially in catastrophic mechanical failure which could cause wheels to lock briefly. -Stranded

I have a high pitched whine noise during acceleration from the transmission area. The noise gets louder with acceleration but goes away immediately when I take my foot off the gas pedal and starts again when you press the gas pedal again.
[XXX] [XXX] [XXX] [XXX] [XXX] Vin # [XXX] 2021 Toyota Highlander 4DR AWD XLE I am writing to report a potentially dangerous transmission defect in my 2021 Toyota Highlander XLE, at approx. 60-70k miles. The vehicle recently developed a high-pitched whining noise while accelerating, which a certified Toyota service technician suspects is internal to the transmission. This exact issue is outlined in Toyota Technical Service Bulletin T-SB-0008-21, issued February 9, 2021, for 2021 Highlanders equipped with the UA80E or UA80F 8-speed automatic transmission. According to the TSB, the cause is worn pinion shafts in the front carrier assembly, and the prescribed repair is complete transmission replacement. Unfortunately, my vehicle was just outside the 60,000-mile powertrain warranty window, despite experiencing the failure consistent with a known manufacturer defect. Numerous other owners have reported identical symptoms between 60,000–80,000 miles, often facing repair costs over $8,000 and multi-week delays due to part availability. This is not a typical wear-and-tear issue. A failure of the transmission at highway speeds or during critical maneuvers could lead to loss of power or control, posing a real safety risk to drivers and passengers. I respectfully urge the NHTSA to investigate this issue further. I am happy to provide: Thank you for your commitment to driver safety.

There is a known defect with transmissions in certain model years of Toyota cars, mine being one of them, per this TSB: [XXX] The transmission can catastrophically fail but Toyota will not replace the defective part unless the vehicle is still under warranty. I had the Toyota dealer verify that the transmission is beginning to fail and requires replacement. The transmission has begun to emit a "whining" noise. Should the transmission fail catastrophically during operation, it could cause a sudden loss of power, seize a drive wheel, or another event causing a loss of vehicle control.

The transmission has gone out on my 2021 Highlander. It was inspected by the Toyota dealer. I was told by them that this is a known issue with these trucks. There are no warning lights but just a whine when driving the car and I believe it does put my safety as well as other at risk as this could go out at any moment.

Transmission makes whine noise upon accelerating. Cannot be fixed except with new transmission. The longer you drive, the longer it affects and damages other parts. Mechanic was amazed that my relatively new Toyota needed over $10k in repairs. Toyota denying there’s a problem.

My transmission started whining at 63,000 miles and my mechanic said it needs to be replaced. However, there is a nationwide backorder on Toyota transmissions. That should be a sign to NHTSA that this is a widespread issue and needs a recall! Of course this was right after the 60,000 mile Toyota warranty. I have extended warranty but it doesn't cover consultations or taxes.

I have a 2021 Toyota highlander platinum. The car makes whining noise when accelerating my car has 70k miles and according to Toyota my warranty expired at 60k miles it’s a common issue with these cars and Toyota knows that but they won’t help with the fix. This affected a lot of people and they want almost 11k for a trans replacement. If it’s a common issue with all their cars then they should take full responsibility and fix the cars. I hope you guys could be of help and hold they accountable.

My transmission is failing in my 2021 Toyota Highlander. Has started making the high pitched whining noise. Fix is to replace the whole transmission. Dealer has confirmed and does have the transmission on order.

Transmission failure at 62000 miles. Toyota issued a service bulletin in Feb 2021. I bought the vehicle new in August 2021 and was not told of service issue. Also, I took vehicle to Toyota dealership for service every 5000 miles up to 55000. I was never told about service bulletin nor advised there could be a full imminent failure of the transmission.

Routine maintenance was done 5000 miles ago. Routine maintenance. At 50,151 miles and routine 50,000 mile maintenance a whistling/whining sound was noted. I was told a new transmission is needed. PLEASE MAKE THIS A RECALL. PLEASE MAKE TOYOTA STOP CHANGING OUT TRANSMISSIONS AT 50,000 miles on the regular. There is a known TSB, but so many VIN's are outside of this range experiencing the exact same issue that it is inconceivable that Toyota doesn't know they have a problem. Having a warranty that covers it is a band-aid. The wear and tear on the overall engine and parts due to transmission failure means they are knowingly selling cars that will fail. Why isn't it told to every buyer to expect transmission failure at 30-50,000 miles at the time of purchase? TELL US AND THEN LET US DECIDE IF THAT IS HOW WE WANT TO INVEST OUR MONEY IN OUR CARS. My first Toyota and my last. AND what is worse, the NHTSA KNOWS about all these incidents and just lets it ride. We have lost the consumer in the values we hold as a country. Insurance doesn't mean insurance. Transmissions are only worth 30-50,000 miles when it should be 200,000+ by now. Quality standards are there for a reason. Having a powertrain warranty that protects the manufacturing IS NOT how it was intended. FORCE TOYOTA TO FIX THIS ISSUE. STOP SELLING CARS WITH FLAWED TRANSMISSIONS. I feel taken advantage of and am stuck with a car I no longer want, (because as the service advisor said, "if it happens again, you will still be covered at no cost to you?!") - this is not ethical or technically sound.
A whirring and grinding sound from transmission when put into gear. Intermittent sluggish when accelerating.

Transmission whine
When accelerating there is a whining noise coming from the front of the vehicle. There was no warning lamp that came on just the noise is what prompted me to take it to Toyota of Hattiesburg to be diagnosed. The transmission is what malfunctioned. Yes Toyota confirmed the problem and said my transmission needs to be replaced. I am very disappointed because Toyota’s has the reputation to last forever. As this is my 3rd Toyota and I have been very happy until now because Toyota is not taken responsibility for this problem that is continuing to arise in the transmissions. I have attached the paperwork showing what Toyota said.

2021 Highlander has 103000 miles. Transmission started a whine that only presents under acceleration. It follows the speed of the car, not the engine speed and is getting louder. My [XXX] granddaughter asked today what is that loud whining noise. It was diagnosed by my mechanic as another bad Toyota transmission. They stated it could stop working at the most inoperative time.

I am filing this complaint due to a severe transmission failure in my 2021 Toyota Highlander XSE, which I believe poses a significant safety hazard. At approximately 70,000 miles, the vehicle’s 8-speed automatic transmission failed. Prior to this failure, I reported a persistent gear noise (described as a whining or grinding sound during acceleration and gear shifts) to my Toyota dealership [Shore Toyota] when the car had less than 60,000 while the vehicle was under the 5-year/60,000-mile powertrain warranty. The dealership dismissed the noise as “normal” and did not perform diagnostics or repairs, despite my concerns. The gear noise worsened over time, leading to more frequent noise and shifting, jerking, issue failure in May 2025. The noise occurres while driving from 0 to at 35mph. I later learned that the 2021 Toyota Highlander’s 8-speed transmission (UA80E/UA80F) has known issues, as documented in Toyota Technical Service Bulletin (TSB) T-SB-0008-21 (issued February 2021). The TSB describes a whining noise identical to what I reported, requiring a full transmission replacement for affected vehicles. Numerous other owners have reported similar failures, with some experiencing delays of 3–6 months for replacement parts due to backorders. My vehicle’s symptoms match the TSB, and the dealership’s failure to address the noise during the warranty period likely allowed the defect to progress to catastrophic failure.

The transmission started making a whirring and grinding noise so I took it into the mechanic who notified me that Toyota put out a TSB on this issue in February 2021. I leased this vehicle in April 2021 and it was never disclosed to me that I would experience a transmission issue down the line. At the end of my lease, I purchased the vehicle and again it was never disclosed to me of this issue. I immediately took the car into the Toyota dealership where they heard the noise and confirmed it is the transmission defect that Toyota previously identified. I am ordered to bring my four minor children from Las Vegas to Los Angeles minimum once a month and my fear is getting stuck on the 15 freeway at 75 miles an hour in the heat of summer. This is a huge safety issue and this matter should have been a recall. I understand from the Toyota service manager that Toyota did not redesign the transmission so even if I get a new transmission it will experience this issue again. At $11,000 for a new transmission or $4500 for the extended warranty, it isn't right that the consumer is on the hook for a defect Toyota knew about and didn't disclose. This is auto fraud and negligent. A car is a hefty investment and Toyota took advantage of the public. They should be held accountable.

There is a known flaw with this car that the transmissions fail prematurely. There is a technical service bulletin (TSB0008-21) released 2 months before purchasing the car on this exact issue and we were not made aware before purchase. Toyota has not recalled these vehicles and this applies to a very select serial number range of transmissions implying a manufacturer defect even further. Now my car, with 68k miles, is expected to have a transmission replaced at full cost. There are many forums discussing this issue and I hope that more people come forward because this is clearly a defect in the design that Toyota should be responsible in fixing.

Around 76k miles, a whining occurs upon accelerating. Hear ever so slightly in 1st gear. Gradually is more evident as the speed increases. At 78k I decided it was definitely getting louder and was concerned after researching and learning that MULTIPLE 2021 Highlanders have needed transmissions replaced. I brought it in to a mechanic who searched for every possible problem, but ultimately came back to tell me it is my transmission failing.

Engine/Transmission 'whining' noise upon acceleration. We cannot drive it, three places said we shouldn't - it will only get worse, and eventually fail. No one knows when. My wife was driving on interstate when it firsts occurred, she couldn't get to the side fast enough. My wife feels unsafe driving it alone and with our young son. We are receiving very high quotes - despite the fact that they don't seem to be doing any real diagnostics. It seems to be a well known problem that only Toyota can address, as their design seems to have caused this dangerous problem and their supply chain issues seem to be common knowledge to many in the industry. Toyota service tells us at least a two month wait for a new transmission to arrive. Then three of four days to install. My wife feels very unsafe driving this vehicle knowing it could just stop operation at any time.

While driving the vehicle will wobble, shake and make grinding noises at lower speeds and at higher speeds.

The transmission has a whining noise caused by the front carrier pinion shafts. There is a TSB out for the transmission issue. Transmission has been inspected by a technician. No warnings - the noise was a warning I suppose. It first appeared in March 2025.

The transmission started to make a higher pitch sound when accelerating. We brought the vehicle in for evaluation @ 70,500 miles. We were advised the vehicle needed a new transmission for $ 9,900.00 Not even 4 years old, and Toyota Warrantee department said past the 60K drive train warranty so no support from them.

There is a TSB about the transmission whine between certain serial numbers. My transmission was outside of the range but started whining. I took it to the Toyota dealership and they advised me that the transmission needs to be replaced.
There is a whining noise that occurs when the car is accelerating. At times, there car will skip when accelerating. There is also a vibration. I was informed the issue is with the transmission. A bad transmission can make driving very difficult, potentially causing the vehicle to stall or become unresponsive, and can be a safety concern. I drive my child to school daily, over an hour from our home, and drive to homes to provide hospice care to terminally ill patients. This issue causes great concern, both financially and for safety.

The transmission is whining at medium speeds of 30-35 mph. The transmission started making the noise about 3 weeks ago. It appears that Toyota was aware of the potential defect in the transmission as Toyota issued a technical service bulletin (T-SB-008-21 and NHTSA # 10188917) on February 9, 2021. The TSB was sent to dealerships 17 days before we purchased the vehicle. Toyota took no steps to notify the owners or to prevent the sale of the vehicle with a know defective transmission. The TSB said the only cure to the defect was a transmission replacement. Toyota offered no extension for this drivetrain defect beyond the standard 60 month/60,000 mile warranty. Our vehicle is just outside of these parameters at 70k miles. The vehicle should not have been sold with know defects in the transmission and Toyota at the very least should offer to extend the standard warranty.

I purchased a new 2021 Toyota Highlander and began to experience a clicking noise coming from under the vehicle which grew in intensity. The vehicle has 76,000 miles. I regularly took the vehicle to a Toyota dealership for service where they never mentioned any needed service for the transmission. I informed the dealership of the clicking noise where I was told by a Service Technician that they have seen a large number of newer Toyota Highlanders experience transmission failures. I asked the Technician if a recall was issued and he simply shrugged his shoulders and walked away. This is a serious issue affecting a major component of a vehicle and safety, it is unconscionable that a major reputable manufacturer such as Toyota would be aware of a major defect and refuse to address the issue.

The transmission began to do a whining noise at 70K which is a signal of soon deterioration and failure. Toyota acknowledged the widespread issue but for only a very small portion in the T-SB-0008-21, though covered only under the standard 60K warranty. My car doesn't fall in the range of transmission mentioned in the TSB, though it is the same UA80 transmission model, and the symptoms and the problem is exactly the same as verified by the dealer. I have learned that many Highlander owners with UA80 transmissions are having the exact same issue around or right after the 60K miles.

Transmission starting whining at 65k miles. Toyota corporate will do nothing since its technically out of warranty. Transmission in a Toyota should not fail at 60k miles. This is huge problem with this year vehicle. The only solution seems to be NEW transmission which is $8-10k.

2021 Vehicle has 105,000 miles, purchased certified used in 2023 from dealership. Whining noise with acceleration began so we brought to dealership to get the recalls fixed and asked about the whine on acceleration. Vehicle inspected at the Toyota dealership and service advisor stated that the transmission needed a full replacement and would have catastrophic failure if we keep driving. Advised that a new transmission is needed and cost of replacement is $10,000. The warranty no longer applies as the vehicle has over 100,000 miles. However we purchased with 66000. Technical service bulletin (T-SB-0008-21) notes that transmission issue recognized by Toyota since 2021. Hundreds of posts and complaints by Toyota Highlander owners with 2021 models can be found online. The dealership tried their third party warranty and the claim was denied. There should be more support from Toyota in supporting customers in replacing the transmission as it is clear this is a known issue. A recall is needed and a remedy in place. There is no reason a transmission should fail this early. Toyota needs to provide more support for this safety issue and replace the faulty transmission.

Vehicle has 84,000 miles, purchased new in 2021. Started to experience whining noise with acceleration and irregular shifting of gears. Knew it was a transmission problem. Vehicle inspected at the Toyota dealership and service advisor stated that metal shavings are seen in the transmission oil. Advised that a new transmission is needed but may take several months before it is available. Cost of replacement >$9000. The extended warranty that I purchased previously no longer applies as the vehicle has more than 72,000 miles. Technical service bulletin (T-SB-0008-21) notes that transmission issue recognized by Toyota since 2021. There should be more support from Toyota in supporting customers in replacing the transmission. There appears to be many other owners who have experienced similar issues. Due to well recognized safety issue related to transmission failures, a recall should/need to be pursued. Please help.

My transmission has a whining noise and is just over warranty. It is likely to fail soon. Toyota knows the transmission has had issues and has only recalled a select number of them but the issues are all over the board. The issues is consistent across all makes that use the UA80 trans mission (Sennia, Highlander, Camry, etc). In fact, these transmissions (new and remanufactured) all out of stock across the country because the issue is so bad. Research verifies this issue. Please see actual customer experiences below.

On February 16, 2025 the vehicle was parked. The temperatures that day were in single digits. After approximately 1 1/2 hours the 12V system was drained. The driver panel was blank and the vehicle did not respond to any attempt to start. This vehicle had a similar incident the prior year, also in extreme cold conditions. During that incident the vehicle was towed to the dealership. They recharge the 12V system and did not find any problems once the faults were cleared. For the February incident, an attempt was made to jump start the vehicle. After the jump start the driver panel was active, but the vehicle reported a hybrid system malfunction and would not start the engine. The vehicle was then towed to the dealership. Attached is the report from service team. Problem #1. Under cold weather conditions this vehicle will drain the 12V system leaving the driver stranded in dangerous weather. Problem #2. The jump start procedure leaves the ECU exposed to severe damage. This leaves the vehicle inoperable.

Transmission failure at 94k miles. Driving on I90 the truck started making very loud whining noise. TSB0008-21 was issued by Toyota Feb-21 and I bought my truck Apr-21. Toyota did NOT disclose this to me.Vehicle failure happened exactly like the TSB. Toyota takes no responsibility-extended warranty is 100% unethical as I am still waiting 4 weeks later for repair. Toyota has no new transmissions available either. Please look into issuing a recall- thousands of people are impacted- please investigate. Toyota is choosing profit over people and safety.

39,000 miles- Transmission starting to make a loud whining noise while driving. Dealership stated failed carrier bearing, unsafe to drive as this could cause the transmission to lock up at any moment. Toyota has a TSB out for this and has provided a loaner. My car does not fall within the TSB VIN range however still has same failure.

I purchased my new 2021 Highlander in Sept. of 2021. At about 88K miles, my car started making a whining or buzzing noise when accelerating. I am scheduled to take my highlander to the dealership to be looked at, but in the meantime, research on multiple forums and NHTSA -this is found to be a common issue with the 2021 toyota highlander transmission. Upon further research, I discovered that prior to buying the car, Toyota was already aware of this problem as they issued a Technical Service Bulletin T-SB-0008-21 in February of 2021 yet they did not inform me or hold the cars for sale to correct what could cause accidents when the transmission fails. Upon further investigation, there are numerous people with this problem in their 2021 Highlanders. This needs to be addressed immediately and deserves a recall, as most owners discover this issue after the 60K power train warranty has ended.

I purchased my new 2021 Highlander in Sept. of 2021. At about 70K miles, my car started making a whining or buzzing noise when accelerating. I took it to the Toyota dealership in Fort Collins, CO. They told me my transmission is failing. They stated I needed completely replaced for just a few dollars under $8000. They stated that the Highlander transmissions are on backorder for replacement. They said it could go completely in a year or a month, they didn't know but I couldn't get it fixed for months because of the backordered transmissions. There is no warning light or alert. This is very concerning since I commute at night alone long distances, or if the transmission goes while I'm on an interstate, etc...I did some research and found that prior to buying the car, Toyota was already aware of this problem as they issued a Technical Service Bulletin T-SB-0008-21 in February of 2021 yet they did not inform me or hold the cars for sale to correct what could cause accidents when the transmission fails.

Transmission is shifting roughly and whining. Has to be replaced, on backorder for a month. This is a safety issue as it could fail while driving. Online search finds a service bulletin (T-SB-0008-21) and many, many consumer complaints about the same issue.

The vehicle pulls/jolts foward as I slow down at a stoplight. At first, I thought this was normal, but over the past year, I've noticed something unusual, possibly with the gear shifting. It has become more noticeable over time. It has happened enough where I almost get into a fender bender with the car in front of me. I started researching this issue and it's a common complaint among other Highlander vehicle owners. [XXX] . I reported this issue to the Toyota Dealership and all have stated this was normal. I have also seen other issues with the transmission with the similar year and build. Leading me to believe this car may have an early sign of transmission issues.

Toyota is not trying to own up to failing transmissions especially in the Highlanders. The Highlander started making a whining noise around 50k miles like a supercharger. The dealer said the car needed a whole new transmission. The transmission is available for inspection upon request. The car is hard to accelerate because the transmission is failing without giving any warning signals on the dashboard.

THE DEALER HAS CONFIRMED A PROBLEM ON THE MATTER AND SAID IT WOULD COST $8000.00 TO FIX IT. HAS NOT PUT A RECALL ON IT YET. BUT THERE IS A BULLITON ON THE MATTER.

The car started making a whining.humming sound only while pressing the gas. Took to mechanic and they advised it was TSB 0008-21. I need a new transmission. I drive this daily with my own kids, and several that aren't mine. If the transmission were to go out, I would not be able to accelerate and the care would stop moving. I can't even imagine this happening on a high with hundreds of cars speeding or a busy road. This could cause a bad accident, injury or death. No warnings etc. The noise just started and took right to mechanic. I gave the mechanic a copt of power train warrant and hoping it gets covered and fixed.

Regarding Toyota TSB T-SB-0008-21, ‘Whine or Grind Noise From the Transmission’, issued February 2021: Some 2021 model year Avalon, Highlander, and Camry vehicles equipped with UA80E or UA80F transmissions may exhibit a whine or grind noise from the transmission. This condition may be caused by an issue with the front carrier assembly pinion shafts. This is a widespread problem with these specified transmissions. The noise generally starts around 60-70k miles, just outside the warranty period. Toyota knowingly continued to sell vehicles with these defective transmissions. Repair estimates range from $8.5k-$13k.

My wife’s Highlander started whining under acceleration. I am not a trained mechanic but know enough about vehicles that I k ew it was the transmission. I checked Google for 2021 Highlander complaints and found hundreds of them. The vehicle has 90k on it but luckily we bought the extended warranty through Toyota. I took the vehicle in for service and told them the transmission was whining and needed replaced and would be covered under my warranty. They looked at me strange and said ok sure, we’ll check it out. 4 hours later they called to confirm I needed a new transmission. They estimate it to take be 4 weeks before they receive the transmission. Apparently so many being replaced they are on back order. Luckily we bought our vehicle as a “Certified Pre-Owned” so we get a loaner the entire time. Just sad to see Toyota quality going down hill like it has.

A whine developed while accelerating on the highway. The whine continued any time I accelerated higher than about 35 mph. I suspected it was the transmission and Toyota confirmed I was right. I need a whole new transmission. At 59,000 miles, my Highlander is still under power train warranty. However, my car was diagnosed July 9 and I am still waiting for the part to come in at the dealership more than 2 months later. I was told verbally that I would be able to still drive the car while waiting, but I don't feel safe doing so.

Transmission/differential - Took my car in around 80k miles for a routine transmission service. I got my car back and it started making a whining noise when you accelerate. Never did I get a code, check engine light nothing. Took it back to get looked it since the sound never went away. I am being told it needs a new transmission. I was told my car transmission was too hot for them to even look at after sitting for 24hr parked! I have read and done a lot of research that this is a common issue and never has been recalled. Even a shortage now on transmissions with so many needing them now! My car is only 3 years old and won’t be covered.. this should have been recalled and or known to buyers before purchasing if it was known to have issues early 2021…

Transaxle Repair/Replacement: recommend transmission replacement due to whining noise coming from transmission due to internal failure. The transaxle is the transmission for front wheel drive vehicles. The transaxle transfers power from the engine to the wheels. Unsafe driving conditions issue is stemming from faulty transmission, not only on this particular vehicle but many 2021 Toyota Highlander vehicles for the same transaxle repair/replacement issue. I have gone to Toyota multiple times before and even with a Technical Service Bulletin in place for this transmission issue, they did not correct the problem, nor fix it while it was under warranty. Toyota has been aware of this Technical Service Bulletin since Feb 9 2021. T-SB-0008-21 [XXX] Owners of the 2021 Toyota Highlander have reported various transmission problems, including: Whine or Grind Noise: Some vehicles exhibit a whine or grind noise from the transmission, which may be caused by an issue with the front carrier assembly pinion shafts1. Jerky Gear Shifts: Drivers have experienced jerky gear shifts, especially when accelerating from a stop or slowing down to very low speeds2. Delayed Shifts and Hard Shifts: There have been complaints about delayed shifts, hard shifts, and lurching when shifting gears3. Transmission Slipping: Instances of the transmission slipping between gears and jerking when accelerating have also been reported4. Safety Concerns These transmission issues pose several safety risks: Loss of Control: Jerky and delayed gear shifts can lead to a loss of control, especially in situations requiring quick acceleration or deceleration. Increased Accident Risk: Transmission slipping and hard shifts can cause unexpected vehicle behavior, increasing the risk of accidents. Driver Distraction: The noise and irregular shifting can distract drivers, reducing their focus on the road. Mechanical Failure: Persistent transmission issues, or stalling.

Excessive whining noise, shift flare. The vehicle is only a couple of years old. I was told by the dealer that the transmission will likely need to be replaced. There are numerous complaints within the Toyota Nation forums. It was recommended that we report the incidents here, as having a large number of cars on the road with failing transmissions can certainly be considered a road hazard/safety issue.

While parking, the shifter was inadvertently left in reverse. The engine was turned off while foot was still on the brake. After preparing to exit the car and removing my foot from the brake, the car began rolling forward until I noticed and slammed on the foot brake. We are used to the vehicle parking brake engaging automatically as there is no way to do so manually, that we know of. There was no warning that the shifter was not in park and no audible or noticeable visual notification that the vehicle was not in park. In some cases, on a flat surface when the vehicle wasn't in park, it didn't allow me to shut off or arm the security system. In this case, I was able to stop the vehicle and fortunately there was nothing in front of the vehicle. Since the vehicle was powered off, anti-collision likely would not have stopped a collision.

Vehicle self drained 12 volt battery, causing hybrid drive system to not start up, leaving vehicle stranded, wife stranded alone at night. Dealership installed new software, 2 days later the hybrid drive system glitched again and this time the 12 volt battery was not drained but the vehicle hybrid system would not go into the ready mode and left the vehicle stranded, again with wife alone at night. Took to the dealer, service dept said "no trouble found". Has not glitched again but no longer trust this vehicle. Warning lights? Just about every light on the dash was flashing. Center screen said "hybrid system failure"

We rented this vehicle from Avis at Detroit Metropolitan Airport on Tuesday, 11/22/22 at approx. 7:50 pm. It was raining, cold and temperature was dropping. We drove approx. 1/8 to 1/4 of a mile from the facility. As we turned left on to a major roadway (Goddard) southbound, I turned on the rear defroster. Suddenly, the engine went into limp mode. I tried to make a U-turn to drive back to the facility. Engine lights flashed (low oil pressure, check engine, etc) and then the engine stopped. We barely had enough power to turn the vehicle out of the turn lane before we would have been struck by a bus. We sat in left northbound lane of Goddard for approx. 2 min without our hazard lights on. The vehicle would not start. I then pressed the defroster again and the engine fired up. We drove back to the facility and demanded a new vehicle. While we waited for a new vehicle to be prepared, I demonstrated to the manager what had happened. Again, after depressing the rear defroster button, the engine shut off and would not restart. Again, after turning off the defroster button, the engine started back up. This engine condition was replicated multiple times. I warned the Avis manager not to rent this vehicle as it was a death trap.

On July 19, the car was parked and refused to start. Tried Jump start and the gas was at more than half a tank. The car would operate for 30 seconds, stutter and then stop. On July 20, took the car to ED MARTIN TOYOTA in Noblesville, IN. They could not diagnose the issue. Replaced Fuel Pump system. Evaluated all electrical and no issues observed. Escalated to TOYOTA Regional Engineering to teoubleshoot. The car is still in the shop with no root-cause. If the car was in motion and this issue would have occured, could have resulted in a serious accident.

Several minutes after leaving my vehicle once I parked and shut the engine routinely, it rolls back a hundred feet and crashes into another vehicle. When I come back I became aware of this as I noticed the back of the driver side of my vehicle is lodged into the side of another vehicle. This caused damage to both vehicles.
