2022 HYUNDAI TUCSON HYBRID Power Train Problems

I’ve experienced repeated electrical and mechanical issues with my 2022 Hyundai Tucson Hybrid. These include full battery drainage without engine activation (leaving me stranded), multiple warning lights, and recently a heater failure that remains unresolved. I’ve had over 8 service visits in two years, and Hyundai has not responded to my formal letter. A detailed timeline is available if needed.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The hybrid powertrain system, transmission, or engine appears to be malfunctioning. The vehicle hesitates or stalls when pressing the gas, losing power as if it doesn’t recognize when to transition between EV and gas mode. Yes, the vehicle is available for inspection upon request. 2. How was your safety or the safety of others put at risk? The issue caused the vehicle to lose power unexpectedly, particularly while driving at highway speeds, which forced me to pull over multiple times for safety reasons. This happened on [XXX] before the [XXX] Tunnel, creating a hazardous situation in heavy traffic. If the vehicle stalled at the wrong moment—such as in an intersection or while merging—it could significantly increase the risk of a crash. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? No. I have taken the vehicle to a Hyundai dealership, but no official errors or diagnostic trouble codes (DTCs) have been detected. The dealership has not confirmed the issue unless I agree to high-cost diagnostics that may not guarantee a resolution. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has been looked at by a Hyundai dealership, but no official findings or resolutions have been provided. The issue persists, and no recall or technical service bulletin (TSB) has been mentioned to me as a possible cause. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? No warning lights, error messages, or dashboard alerts appeared before or during the power loss. The issue first started occurring at approximately 35,000–40,000 miles and has continued to around 50,000 miles. The first time I noticed the problem was during a long-distance drive from Los Angeles to CO INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5

The hybrid system flashes "Check Hybrid System" then the check engine and check HEV lights are illuminated. The vehicle loses power and even with the gas pedal pushed firmly to the floor the engine isn't producing power. This is a safety issue because I've lost power while driving on busy roads and can't clear the intersection, etc. This was reproduced at the dealership and Hyundai is performing a warranty replacement of the "hybrid system". I wanted to make NHTSA aware of the issue because on the Hyundai forums I'm seeing similar reports made. There is an open campaign to update the software for the hybrid system, 9B4, but this software update did not fix the issue.

While driving, my vehicle suddenly lost all power and didn't respond to the accelerator. The "check engine" and "hybrid system failure" lights came on, jeopardizing my safety and that of other road users. The car overheats significantly, to the extent that the air conditioning only blows hot air. This situation forced me to pull over on the highway shoulder, creating an additional risk for everyone involved in traffic.

The contact owns a 2022 Hyundai Tucson. The contact stated while attempting to drive through a yellow light, the vehicle failed to accelerate upon the depression of the accelerator pedal without warning. The same failure occurred soon after while on a highway ramp. The contact attempted to merge onto the highway, but the vehicle failed to accelerate with the accelerator pedal depressed to the floorboard. The contact pulled off to the shoulder of the highway and restarted the vehicle; the vehicle resumed normal operation after the engine restart. The dealer was notified of the failure and an appointment was made to have the vehicle serviced. The manufacturer was also notified of the failure. The vehicle was not repaired. The failure mileage was 32,340.

Mileage: 32,340

1) Transmission: while driving car jerks. when I’m accelerating from a stop sign or stop light the wheels kind of feel like they’re spinning/shaking and driving over gravel when I accelerate, before it actually starts and shifts gears. Car accelerating but not moving. 2) Not safe. Almost hit other cars around and people. 3) Dealer confirmed and replacing with new transmission. 4) No warning signs

On 9/3/23, driver was waiting at a stop sign to turn left. When driver accelerated into the highway, there was no power and the vehicle would only go 5-10 mph. Warning lights came on to check the hybrid system with the HEV indicator light. Driver pulled over. Restarted car and engine was stuttering. Was able to drive a few miles to a safer location. Started car on 9/4/23, again it had a rough start. Driver waited until the vehicle sounded normal. The vehicle immediately lost power and could not accelerate when on the main road. Called Hyundai and they were unconcerned. We are in remote Alaska, 250 miles from a dealership. Because it happened on a holiday weekend, we have been unable to contact the service department yet. Vehicle is available to be inspected. Safety is a huge risk because the car suddenly stops propelling forward. I'm afraid we will get rear-ended because of the sudden loss of power. It is a danger to ourselves and others. I'm also concerned that we will be stranded because the car has to be stopped when this occurs. We were supposed to be enjoying a trip for a week, and now we don't trust the vehicle and will likely need to go home early and lose hotel costs. This issue will wind up killing someone because there are reports that these Hyundais are stopping in the middle of the highway. Please hold Hyundai accountable.

The car shook and then lights and alarms went off indicating something went wrong with the hybrid system. The car stopped accelerating, would shake, and then accelerated no more than 10 mph. It was absolutely crazy! Luckily, the highway that I was traveling on was not a busy one at the time because all I thought was this could have been a major accident if on a fast moving freeway. I managed to pull over and started reading online about this issue occurring with other customers who purchased the same or similar vehicle. So, I found a post and had shut the car off for 5 minutes, then restart and sit for 10 minutes, and then the car should work. It did! However, during the time of waiting I did reach out to the dealership and they said if the car is working there is nothing they could do. So, I assumed it was safe to use travel to work for a meeting and set up my classroom for the start of the new school year. On my way home from school, the issue happened again. I immediately contacted the dealership and was able to get the car to them. They started running diagnostic tests and currently have the vehicle on hand. However, I don't really feel safe now with this car given the circumstances. What if this should happen again? What if this happens to me or someone else who is traveling on a busy highway and it causes injury or even death to an accident. The engine light came on, battery light flickered on and off, the car shook, the car's HEV system warning was going off, etc. Please help and look into this matter. I do not have any documentation of repair as the car currently sits at the dealership, but I was so upset thinking about what could have happened and felt the need to report the issue.

AWD warning light illuminated under 20K miles. Took vehicle to dealer, dealer advised that vehicle was unsafe to drive. Unknown ETA on parts or repair time. Dealer did advised that it's a warranty issue. Other circumstances surrounding this issue: Issue 1 6 Weeks ago wife received email from Hyundai indicating vehicle was due for service. Wife took vehicle to dealer, she was turned away and advised that service was required. Issue 2 I phone Hyundai corporate from work where all calls are recorded. Phone system has beeping sound every 30 seconds. Hyundai rep was also advised verbally that calls were recorded. Into the phone call she asked if she was being recorded and I advised her yes. She said that their policy prohibits customers from recording their calls. I asked for copy of that policy that I never received. Issue 3 I then scheduled appointment with same dealership and took time off work. Arrived and was advised internet was down all day and they couldn't service vehicles. Was advised I would receive callback. 3 weeks and never received. Issue 4 Approx 6-8 weeks into this issue and revisited dealership. Within 40 minutes they advised me the vehicle was unsafe to drive. Summary It is believed that the vehicle may have been unsafe to drive for many weeks. Where service facility had opportunity to run diag scan, but never did.

I bought a ‘22 Tucson Hybrid in Sept of ‘22. Upon delivery there were issues w paint & a dent on the rear qtr panel. The bigger issue however, is disconnect in communication between the EV motor, gas engine & transmission. All work is done @dealership and well maintained. History of EV over 8 months: @1000 miles noise under vehicle began. Dealership inspected, all checked out. The dealership has done all servicing as scheduled. From 1000 to 12,000 miles, the vehicle drove best if in sport mode. Sport mode utilizes the gas engine and not EV. When in EV modes, the vehicle runs high rpms or it’s sluggish. It’s never consistent. In some instances; the vehicle will actually stall for 2-3 seconds and kick back on. 1 instance was at a stop light, turning left. Mid turn, gas to the floor, the vehicle stalled for 3 seconds before responding. I was almost hit at 50 mph in the intersection as both motors failed me. The next day, 3 lights came on: An EV, check engine and Hybrid motor light came on, 3 total. My Hyundai app stated: issue communicating EV and Gas motor, EMS communication error. This cleared itself in 36 hrs but I couldn’t drive it safely for a week. I took it to the dealership, everything checked out. 3 days ago @ 17,400 miles, I received a text: Hyundai stated car unfit to drive. DTC code U062300, U111200, U02BB0:Powertrain EMS issue. The techs had it 2 days, fixed it. 3 blocks from dealer, check engine light came on again. I returned it to dealer. I’ve found 32 accounts of these codes resulting in a Hyundai buy-back, new engine, new transmission or settlements. I’m told my EV motor, gas engine and transmission won’t communicate even after software / firmware updates & mechanical changes. I don’t feel the vehicle to be roadworthy and I don’t feel safe driving it, if Hyundai has no fix. I’m told, many sales of this model @ my dealer have the same issues. Bad batch? I paid $47k (car & warr) I’m hoping for a buy back or to get into a Toyota hybrid of = value

Within only two weeks of purchase this new car would suddenly stall in the middle of the road. The computer tells you to pull over. We continued to try and get the dealer to fix this issue, they first ignored us, then they secondly tried and successfully replicated the issue. They said there is no way they can fix the issue. This dangerous stalling in the middle of the road happened numerous times. You will push the pedal all the way to the ground and it won’t go over 20mph. This is a very dangerous issue and these vehicles need to stop being sold. It is very dangerous. We have been left without our money back and without a car to drive for months. We cannot drive the Tucson as it is simply too dangerous and must be towed to go anywhere for salvage.

When driving my car at any speed it will suddenly begin to get sluggish then it becomes unresponsive to me giving it gas and starts to decelerate. When this happens suddenly warning signs on the vehicle go off stating to check the hybrid system and stop the vehicle. When this happens the car then stops functioning. I never know when it is gonna happen. I have been in the middle of heavy traffic and at high speeds stuck in the middle of the road. I have brought it in now four times to different dealerships and contacted corporate and No one can find a problem. I have pictures of the warning signs going off, all I am being told is we don’t find anything wrong when they run their test or try to reproduce the issue, so they can’t help me. This is a very serious and dangerous situation to be driving a car that has and will stall at any given time.

The vehicle is currently at the dealership. I purchased the 2022 hyundai Tucson hybrid limited in April. Have gotten my oil changes done religiously at the dealership. Vehicle is at 22k miles. And had oil change 5 days prior to incident. I was on the way to work and vehicle started to struggle to accelerate, engine began malfunctioning. Vehicle dropped drastically from 80mph Dow to 25-30 mph in short period of time, would have been rear ended if not in right lane already. No warning or previous problems. No warning or check engine lights EVER came on before the vehicle would not drive at all. And was told by the vehicle to “check hybrid system stop safely”. Called roadside and vehicle was towed to dealership. They diagnosed as “the timing chain was ‘missing’ one of the cylinders, causing a loss of power from the gasoline engine and the hybrid system attempted to compensate for lost power, resulting in engine failure” later that day when I arrived from work to get a loaner I was told that it was a broken camshaft and warranty would pay for a new engine.”

Driving the car acceleration will go to zero. You can floor it and it will only go to 20mph. The car asked you to pull over safely. They hybrid battery is at zero and warning signs keep flashing. Has happened over three times on a new car. Dealership can’t figure it out. When I look up “HEV warning Tucson hybrid” there are many with same issue. Very, very dangerous issue.

On three separate occasions the vehicle refused to accelerate after being in a stop and go mode (I.e. traffic/drive thru). All three times an alert popped up on the dashboard stating: HEV Check Hybrid System Stop Safely. The second time this occurred a diagnostic code came up: DTCP112000. In all three occasions turning the car off and restarting resolved the issue at least temporarily. Also- the battery was completely depleted after each incident. Vehicle is at the dealership service center for the second time without and current diagnosis or solution.

My vehicle that I finance is a 2022 Hybrid Tucson it failed at 14,596 miles I had it since November 2021 so for a good 9 months until it decided to finally malfunction. As I been driving it previously for the past month I’ve been hearing the transmission struggle a lot more everyday that I use it. I also noticed that the engine really lacks power, when I accelerate it takes a really long time for the gears to shift which has been getting worse for the past month now. Which is what I believe led up to my vehicle losing complete engine power while I was driving 30mph. I saw on my digital cluster a message saying “Check Hybrid System, Stop the car safely.” In an orange triangle, I had cars backed up close to me and I was confused as to why this was happening to my not even a year old vehicle. This is a major safety issue to me that while I’m driving anywhere my engine will go completely off and I am only to rely on 20mph on EV Mode. If I was on the freeway I could’ve gotten into an accident and with my whole family in the car. I personally feel unsafe driving, it’s my daily driver and my only way to get to work.

While on the highway my car (2022 Tucson Hybrid) lost almost all power while I was driving. I was approaching traffic and started to slow down. The battery light illuminated red and the car was jerking backing forth cutting power and juddering while I was slowing down. Being that I was still in the flow of traffic and my car wasn’t fully dead yet I tried to move out of the road but due to traffic on my right I had to make a left turn. I was still able to get up to about 15 mph, but as I was turning to get off the road all power was essentially cut allowing me to only proceed at about 2 mph. Luckily oncoming traffic was far enough away to slow down. I was practically driving like a grandma blocking two lanes of traffic. I managed to limp my car off the road and at this point a “Check Hybrid System” message was shown. My car was towed and after talking with the dealership it seems the transmission went out. My car is still currently at the dealership waiting to be repaired.

It appears the oil pan is leaking. Upon researching online, other 22 Tucsons with the 1.6L Turbo also have this issue. Unsure if they have reported the issue. I am losing about 10-20 drops/day and unable to get into a dealership until a month later due to no availability at any of my 10 local dealerships. I first began noticing the drops about late March/early April. I took delivery in September 2021 and at the time it started it was right after the first oil change...maybe 6000 miles? I smell oil in the car after getting off of the highway from driving 15 minutes. The smell lingers until car is stopped. There are no warning lamps on the dash and via the vehicles telematic/infomatics the oil level is still at 100%, however I have evidence of leakage as I have put oil soak pads under my car and every day there are drips. I'm hoping the car can hold out until I get to a dealership in mid June and not burst into flames. I called the dealership that had the soonest availability and mentioned I have a leaking oil pan and the advisor still said no available time slots. Didn't offer that I could bring the car in on an emergency basis. As depicted in the photos, I am unable to remove the undercover, but there is no damage that I ran over anything. The engine bay is free from any oil on top.
