What 364 owners told NHTSA about the 2022 Hyundai Tucson Fuel Cell

On 3 occasions over my 18-month ownership of this certified pre-owned Hyundai 2022 Tucson, the vehicle surged suddenly forward WITH BRAKE APPLIED at creeping (parking) speeds of 3-4 mph. No warning lamps were observed. On the most recent (3rd) occasion, a crash over a sidewalk and into a storefront caused $10,000 damage. No pedestrians were harmed, no airbags deployed and neither passenger was harmed. The service department is "unable to duplicate" the surging behavior and declares the car mechanically "safe to drive."

My 2022 Hyundai Tucson Experience, a sudden transmission failure at approximately 92,520 miles. The vehicle develop shifting issues and abnormal noises before losing propulsión. While driving. Hyundai diagnosed and internal Transmission failure and approved transmission replacement. I’m concerned about the sudden loss of proportion and the safety risk this creates. Hyundai proposed repair is to replace the transmission with a rebuild remanufacture transmission rather than a new transmission. I am concerned about the reliability of the repair following a complete transmission failure.

I am submitting this complaint regarding my 2022 Hyundai Tucson equipped with the 2.5L engine. The vehicle has experienced multiple incidents of severe engine misfiring while driving. During these events, the engine begins to shake violently, the entire vehicle vibrates, and engine power is significantly reduced. The vehicle becomes unable to accelerate normally, creating a serious safety hazard, especially when driving on highways or in traffic. The malfunction has occurred several times. Diagnostic trouble codes P0302 and P0303 have been recorded, indicating cylinder misfires. In some cases, turning the engine off and restarting it temporarily restores normal operation. On other occasions, adding fuel system cleaner appeared to temporarily improve the condition. However, the problem eventually returns. Because the condition is intermittent, the Hyundai dealership has been unable to reproduce the failure during inspection and therefore has not performed a repair under warranty. Despite multiple visits, the root cause remains unidentified. I am concerned that the sudden loss of power and severe engine vibration could result in an accident if the vehicle is unable to maintain speed or accelerate while traveling at highway speeds. This issue has significantly affected the safe operation of the vehicle. I request that this matter be investigated, as it appears to be a recurring safety-related defect.

The car keeps loosing power when it is over 90 degrees outside. On my way to work in the morning it has plenty of power but on my way home around 5 or 6 PM it struggles to gain speed. I’ve already had all the fuel injectors replaced so I don’t think it is related to that. It mainly happens when I slow down but not to a full stop around 20 MPH. Then it struggles to accelerate after that.

Component or System That Failed: After a routine oil change at Rick Case Hyundai of Roswell on Saturday, \[insert date], my 2022 Hyundai Tucson began shaking significantly. The dealership later informed me the issue was related to a **malfunction in the fuel injector system**. The vehicle is currently at the dealership and available for inspection upon request. How Safety Was Put at Risk: The shaking occurred immediately upon driving away from the dealership and worsened rapidly. I was concerned about losing control of the vehicle orengine stalling while driving, which could pose a danger to myself, passengers, and others on the road. I returned the vehicle immediately to avoid further risk. Reproduced or Confirmed by Dealer or Service Center: Yes, the problem was confirmed by the dealership (Rick Case Hyundai of Roswell). They diagnosed the issue as being related to fuel injector failure. I am waiting on a written report and confirmation of warranty coverage. Inspected by Manufacturer, Police, Insurance, or Others: At this point, the issue has been inspected and diagnosed by the Hyundai dealership. It has not been inspected by police, insurance, or any other outside parties. Warning Lamps, Messages, or Other Symptoms Before Failure: Warning Lamps, Messages, or Other Symptoms Before Failure: Yes, the check engine light turned on shortly after I noticed the vehicle shaking.

I have a 2022 Hyundai Tucson with about 15k miles on it. I have had it serviced twice for oil changes and the recommended manufacture recommended maintenance. However, I have noticed a SIGNIFICANT loss in power upon acceleration with this vehicle. My new car drives very rough and this is a safety issue due to the fact when entering the interstate, the car will not increase speed as requested putting myself and others on the road in danger. Additionally, simple maneuvers like turning into cross traffic are of concern because the vehicle doesn't respond to acceleration when accelerating from 0mph as well as in stop and go traffic. There are no engine lights or codes that I can visibly notice but even in sport mode the acceleration of the vehicle is not responsive. This is a KNOWN issue at Hyundai as one local dealership offered me a service visit 6 months out because they are so overbooked with these issues. A quick Google search also brought up numerous owners experiencing similar and and escalated issues to include complete engine failure and vehicle overheating. This vehicle needs to be recalled immediately! I experience this loss of power EVERY SINGLE TIME I DRIVE and I don't feel safe driving my new car anymore. I have mentioned this to my dealership and they are going to take a look at it today. Occasionally, the car will also indicate to me that I should keep my hands on the steering wheel when I typically drive with BOTH hands on the steering wheel.

All electrical systems proceeded to malfunction with the check engine and driver safety system warnings blaring. Vehicle proceeded to accelerate from 10-40 mph on its own for approximately 400 meters on the freeway.

12/02/2022 while parking the vehicle in a parking spot in a parking garage, vehicle suddenly lurched forward causing the vehicle to hit the parking garage cement wall. This caused him to hit his head very hard on the steering wheel. The air bag deployed after he hit his head. The Air Bag did not protect him. He did not hit the accelerator pedal, and the vehicle accelerated by itself, which caused it to hit the parking garage wall. Shortly after this occurrence; he was at the Post Office, to drop mail in the mail box, and he very slightly removed his foot from the brake pedal to move the vehicle up a foot or two, and the vehicle lurched ahead approximately four to six feet. Again, he did not hit the accelerator pedal. Luckily, there was no other car in front of him or the vehicle might have hit it. Prior to the self acceleration of the vehicle in the parking garage and at the Post Office, this issue occurred while he was driving on the highway. He was going 55 mph and the vehicle suddenly went 75 mph. He was at a place where there is an exit, and he would not go that fast at this particular area. He explains he did not accelerate the car himself. He was so concerned about the vehicle self accelerating that he immediately got off of the highway to look under the hood to see if there was some explanation for this. We addressed this issues with the Hyundai dealer. On 01/06/2023, according to the report from them they drove the vehicle around their building and then looked for engine or transmission, and they said there were none.

Purchased this vehicle 12/2021 it hesitated on pick up but drove good after that nice look but the headlights are bad at night. First month I had a bad scare as when attempting to stop the brakes gave out, I had to pump multiple times to get the car to stop, this happened again about 1 month ago. On 10/10/22 while attempting to park in my driveway which is on a hill the car did not want to accelerate when pressing the gas and many lights turned on the dashboard. Warning, check engine, brake, front collision, etc. I have not had any accidents for the collision light to be on anyways. I turned the car off and restarted it I even disconnected the battery but still nothing the car has power because it does turn on and the lights, radio work but it just would not accelerate. I'm on a very dangerous hill lucky this happened late night when not much vehicle traffic. The next morning 10/11/22 around 10 am Hyundai came to pick up the vehicle. I passed by that day around 4 pm to see what was going on. They had not checked it yet which is understandable we ask the guy when he thought it would be checked out and he responded that towed vehicles take longer to be checked, we asked for a loner and they said they did not have. Saturday 10/15/22 went again, the car was still in the same spot not looked at yet, today 10/19/22- 1 week and 1 day they have not checked the car and we were told they had a lot of cars to work on and we were far down on that list. So basically they will probably take 2-3 weeks to even look at it and if any parts are needed it would probably take another month and without a loner. So we the paying clients have to figure it out. This is very unacceptable not to mention how scary it was for the car to completely give out on a hill thank god no one was driving or walking behind me. I have been driving for 29 yrs and have never experienced something like this. This car can potentially be deadly specially to a new driver.
