2022 TOYOTA HIGHLANDER Power Train Problems

Transmission failed at 75K with no warning lights or prior evidence.

I had been driving my 2022 Toyota Highlander XLE with 46k miles that I just got for about two weeks, so about 10 days out of the 14 i actually drove it from home to work and back home. Within those 10 days driving the SUV, 8 mornings and one afternoon the highlander engine had issues accelerating and shifting gears. Basically when pulling out on to a highway from a side street coming down a hill when pressing the gas to enter the highway and flow of traffic the engine stuttered from zero to 20mph causing the entire SUV to jerk repeatedly and the gears would have issues shifting from first to second. I had to let my foot off the gas pedal then press again repeatedly as the SUV kept jerking trying to accelerate forward stuck no more than 20 mph for 30 seconds then started to even out and climb up after a minute. I have caught this on video twice. This has caused me to hold up traffic on the highway behind me with no where to pull off because my particular side street comes out from a gulch cliff side. No check engine lights came on each time. I took it to an auto shop that did a minor test drive and suggested it go directly to Servco Toyota as it should have powertrain warranty on it still and they believed it was a fuel pump issue. The issue did not happen with this auto shop but I showed them the video. I scheduled an appt at Toyota and it is with them now. They did 2 test drive but could not replicate the issue and could not see any codes coming up. I opted to leave the vehicle with them to do more test drives where the issue has happened as I do not feel safe driving it and the manager also said they did not feel safe having their techs drive it so the manager will do it. Without check engine light/code they are saying they cannot check the fuel pump or do anything else but will try to do more test drives to replicate the issue. I have seen numerous Reddit, facebook group posts, and a petition about this same issue but no official recall or word from Toyota.

The contact owns a 2022 Toyota Highlander. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed, but the vehicle failed to accelerate as intended and made an unusual whining sound. No warning lights were illuminated. The contact's husband, a certified mechanic, diagnosed that the transmission had failed. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was filed. The contact related the failure to several unknown TSBs. The contact was informed that the repair was not covered under warranty. In addition, the contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 71,000.

Mileage: 71,000

early transmission failure and whining at 40,000 miles

Car developed a whining noise coming from transmission at 63,000 miles. Known manufacturing defect that will lead to transmission failure. No recall issued and Toyota would not extend warranty. I do not feel safe driving the car pending a transmission failure. Toyota’s solution is to replace the transmission at a cost of $9000.

Premature transmission failure

AUTOMATIC TRANSAXLE WHINING FROM 35MPH-45MPH ACCELERATION. Needs to be replaced this is the third vehicle this week the dealership said had the same issue.

Four days ago, engine started making a whining noise when accelerating, especially in lower gears. No warning signs. 2022 Highlander Platinum is 3 years old, 80K miles, out of warranty; no extended warranty purchased due to historical, stellar Toyota reliability. Toyota service department at Toyota dealership today said whining is due to a bearing issue within the transmission (my personal mechanic inspected and said that is also likely) and cannot be repaired. Transmission could last another 10K-20K miles they said, before it becomes undrivable or just drops, causing a potential safety issue. Net, the entire transmission needs to be replaced to the tune of $9186. Just shocking.

About 4 weeks a go i started hearing a whining noise from my Highlander. Thinking it was a belt we replaced. Whining continued to get worse only on acceleration. We are at 88,000 miles and it is now at Toyota getting a new transmission. Is there not something that can be done about this? I have read thousands of articles that show the UA 80E/F transmissions that are in the 2021-2022 models are junk. Luckily we bought a Toyota VSA and it is covering it. What about after 100,000 miles. Whats to say after another 80,000 it won't go out again which will cost me the $10,000. When the dealers put new transmissions in these vehicles are they using the same parts for the UA 80 E/F or the upgrade parts that fixed the 2023? If we have a VSA it should extended a year past the 100,000 mile mark because of the issue or they should have to replace them completely to match the 2023 models.

2022 TOYOTA HIGHLANDER TRANSMISSION IS MAKING A HIGH PITCH WHINING SOUND AND IS GETTING WORSE. MY WIFE DRIVES 20 MILES A DAY, 6 DAYS A WEEK AT 65 MPH TO WORK AND THE TRANSMISSION NOISE IS GETTING LOUDER. IF THE TRANSMISSION FAILS AND LOCKS UP, IT COULD CAUSE AN ACCIDENT. THE VEHICLE WAS TAKEN INTO FINDLAY TOYOTA IN PRESCOTT AZ. AND WAS TOLD THE TRANSMISSION IS DEFINITELY FAILING BUT WOULD NOT WARRANTY THE ISSUE BECAUSE SHE WAS 2500 MILES PAST THE 60K WARRANTY.

Ua80f/e transmission in the 2018-2022 Toyota Highlander are defective. Mine has a loud whistle while accelerating. Problems have been acknowledged by Toyota however they’re refusing to fix.

I own a 2022 Toyota Highlander XLE (UA80E transmission, ~66k mi). The vehicle exhibits a severe transmission defect: uncommanded braking/drag at 35–40 mph and sudden loss of power when accelerating from a stop, making merging/crossing intersections dangerous. Two Toyota dealers (Bryan Toyota and Plano Toyota) reproduced the issue, documented the vehicle as unsafe to drive, and recommended full transmission replacement. The failed unit is preserved at the dealer for inspection. (Toyota Corporate Case #250917001779.) This mirrors long-standing defects within Toyota’s UA80 family that Toyota itself has documented: • Customer Support Program ZJC / POL19-04 (4/18/2019)—UA80 whine, harsh shifts, reduced power 2019 MC-10159730-9999 . • T-SB-0160-18 Rev1 (12/17/2018)—UA80 whine/harsh shift/MIL/reduced power 2018 MC-10198131-9999 . • T-SB-0001-18 Rev2 (1/8/2018)—ECM/UA80 mismatch causing harsh shifts 2018 MC-10185780-9999 . • T-SB-0008-21 (2/9/2021)—UA80E/F failures in 2021 Highlander (whine/grind, pinion shaft) 2021 MC-10188917-9999 . The same safety-critical behavior now recurs in my 2022 model. I request NHTSA investigate this as an ongoing UA80 transmission safety defect trend and consider recall/coverage for affected vehicles.

The transmission on this vehicle has failed - I’ve been told by Toyota Dealer Maintenance that I need the transmission replaced on this vehicle with under 70,000 miles and just over three years old. I began hearing a whining noise while accelerating, and brought it in for service. No system warnings.

HIGH PITCH WHINING SOUND WHEN DEPRESSING ACCELERATOR. DEALER DIAGNOSED THE ISSUE AND SAYS THE TRANSAXLE AND TORQUE CONVERTER HAS TO BE REPLACED. ALL STARTED HAPPENING JUST AFTER 60000 MILES SO OUT OF WARRANTY. $8500 REPAIR BILL

UA80 transmission failure

Complaint Description: The automatic transmission in my 2022 Toyota Highlander failed completely at only 62,800 miles. Toyota Brand Engagement Center offered to cover 50% of the replacement cost, but I was informed that the transmission is on national backorder with an estimated wait time of 4–5 months. This leaves me without a safe and reliable vehicle for an extended period of time. The failure is consistent with Technical Service Bulletin T-SB-0008-21 (Feb 9, 2021), which acknowledges internal component failures and abnormal noises (whine/grind) in UA80E/UA80F transmissions. A major drivetrain failure at this mileage is unacceptable and raises concerns about safety, reliability, and Toyota’s handling of known transmission defects. I am requesting NHTSA to investigate this issue as it appears to be systemic and affecting many 2021–2022 Toyota Highlander owners.

While driving my 2022 Toyota Highlander (VIN: [XXX] , 29,427 miles), I have experienced multiple recurring safety defects that Toyota has been unable or unwilling to repair under warranty. •Front collision sensors frequently trigger without any object present, creating a risk of unexpected emergency braking at freeway speeds. •Transmission hesitates and surges unpredictably, sometimes propelling the vehicle into traffic. •In heavy rain, my windshield wipers activated on their own and multiple system failure warnings appeared (including ABS failure), nearly causing a crash. •Persistent startability issue when fuel is below half a tank. •Seatbelt malfunction caused a passenger to strike their head. •Seat heater failure, seat separation, persistent coolant odor, and nonfunctional factory wireless charger since purchase. These defects are intermittent but recurring, and their unpredictability increases the danger. Toyota and the dealer have failed to duplicate the issues during short test drives, but they continue to occur during normal operation. This vehicle remains under factory and extended warranty, yet repairs have been denied. I believe these defects pose a serious risk to myself, my passengers, and others on the road.

Experiencing erratic transmission shifts and jerking. Intermittent in nature.

This is regarding an issue with a 2022 Toyota Highlander with 79,668 miles at the dealership now waiting on a new transmission. On April 15, 2025, the vehicle was taken in to the dealership with whining noise and put on a diagnostic machine. Diagnosed as transmission. Took for second opinion at independent transmission company and stated the same issue. This vehicle is 4, 668 miles over warranty and we spoke with Toyota Brand Engagement and also district manager for this area. We are asking for help in replacement of this transmission costing over $10,000. Toyota was not willing to help in any way other than saying, "Sorry". We had to pay $5000 before the dealership would even order it. Now it has been three weeks and the transmission is still not at the dealership.We continue to make payments on a vehicle that is not even in service. I am seeing numerous incidents on the internet regarding Toyota's faulty transmissions. I am asking for a recall due to the issue of the age of the vehicle and the extreme expense of replacing a faulty transmission with no help from Toyota in any regard. This vehicle has been serviced as required and even transmission fluid change out per recommendation in Nov. 2024. There were never any warning lights that came on prior to failure. We took the vehicle into the service department within a few days of whining noise.

Vehicle is displaying a whining noise, especially when reaching 3rd gear / 35+ mph. Per mechnical review, it is the transmission failing. Only option is to replace the transmission. Similar to an issue already reported on similar models for both 2021 and 2022 Toyota Highlanders. No current recalls exist

Internal failure (dealer indicated a bearing as cause) on transmission leading to entire transmission replacement required. Happened just outside warranty. Problem confirmed by dealership. Warning signs are whining/revving noise when accelerating (starts at about 20mph).

As my wife had the wheels turned and was pulling up to the curb stop in a parking spot the car suddenly lurched forward without putting the accelerator on and went up and over the curb. Stop and hit a pole. my thoughts are is that the engine possibly changed from hybrid to gas or vice versa and as my wife’s foot was let off on the brake to inch forward to the curb stop it suddenly lunged forward as previously stated.

Car fire (total loss of vehicle) after hybrid malfunction. My family and I were traveling west bound on [XXX] near Crawfordsville Indiana on [XXX]. Trooper Chelsey Smith from the Indiana State Police (CAD # [XXX] ) came to the scene. Our car was traveling westbound at about 70 mph when I got a notification of "a malfunction in the electronic control of the engine, throttle, or automatic transmission has been detected. Contact your Toyota dealer to have your vehicle inspected" - I acknowledged the alert and kept driving, then it showed again 30 seconds later and acknowledged again. About 30 seconds later I received a "Hybrid System Alert" stating "A malfunction in the Hybrid System has been detected. Stop in a save location and contact your Toyota dealer to have your vehicle inspected". The vehicle then notified me that it was reducing power output and we went from 70 to 20 mph in a few minutes. Then while we were going about 20 mph, the vehicle notified me that its going to come to a stop and shut off its power. I engaged the brakes and before coming to a full stop, thick brown smoke came out from the hood on the drivers side. Vehicle cam to a stop and we all jumped out of the vehicle. Within 30 seconds, the car had flames coming out of hood and front drivers side quarter panel. The fire then moved through the vehicle. Fire department came about 10 min later, but worked on it for 30+ mins to put out. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The highlander has been having starting issue where the dash reads that the hybrid system is not functioning and won’t turn over. There is a consumer report program instead of a recall. This is deceiving. This morning the TPMS was reading that all tired were at 32 pounds of air when in fact the right front passenger was complete flat to the rim. Clearly the computer was malfunctioning with not just one aspect of the car but multiple. The local dealership isn’t helpful in that they charge $185 for diagnostic tests.

While having the eco system on, with the active system present by firmly pressing the brake hard at a stoplight, the light turned green. while taking my foot off the brake and the engine turning back on, attempting to accelerate the transmission would not allow me to get through the intersection turning left. I pulled to the far left/slow lane to stay out of other traffic. The vehicle would not allow me to go past 40mph, and the rpm’s would rev between 2000-3000 at low speeds between 10-25 mph. I had my 1 1/2 year old with me in his car seat, and it would have been tragic should this happen on the freeway and this kind of situation happened. Attempting to take it to the dealership, the truck even had trouble going over some railroad tracks with a small mound present. The dealership checked out the vehicle and called it operator error, after inspecting the reported malfunctions and finding nothing. This will not be operator error when someone is seriously injured, or if it happens to be one of their family members driving a similar vehicle.

Highlander with approximately 650 miles on it had a transmission failure while on interstate 69 north of Evansville Indiana. The car seemed to shift into passing gear a few times while the cruise was set and we bumped it off cruise and coasted to a stop . The car would not move after we stopped . There was transmission fluid all over the drivers side and rear of the car and a puddle under it . We called Toyota roadside assistance and had the car towed to the nearest dealer .

When I'm cruising about 35 mph, let off the gas and decelerate, then give a slight bit of gas, I feel a "bump" in the drive train. It's more like slop in the transmission....sounds like a metal To metal noise...this happens after car is driving more then 30 min or 45 min.
