2022 HYUNDAI TUCSON HYBRID Complaints

The check hybrid system light came on just after I tried to accelerate from a complete stop and I had no acceleration. I had the accelerator pushed to the floor and I got no response and was not able to accelerate two different times within 5 minutes of one another. I was in traffic unable to accelerate. I took it to the dealer and they were unable to find anything wrong and told me to bring it back if it happened again.

On August 1st I was on the highway at 55 mph when my 2022 Hyundai Tucson decelerated to 20 mph and would not go faster. This occurred on the highway at 5:45 pm. This placed myself and others in danger as I was on the highway in the center lane at the time of the deceleration. After turning the car in, the dealership returned the car with no repairs but stating that I engaged a button that caused a limit to the car's speed. I didn't understand but took their word. I drove it from the dealership to the store and home. The very next morning while taking my grandson to school at 5:15 am the car decelerated from 45 to 20 mph with my grandson inside the car. This placed myself and a family member in danger along with cars around me. Each time I had to drive to the dealership in unsafe conditions. They stated that I was not engaging the brake enough to charge the battery. I do not know of ANY documentation stating the number of times the brake must be engaged per drive. I have never heard of such engineering that allows a car to only go 20 mph and create a hazard for the occupants unknowingly. The dealership has stated that refuse to fix the problem but I should engage the brakes more often when I drive. The car has spent several months in their care due to continued repairs over the time that I've had it and is currently their because of the engine light being on.

On multiple events brakes would not come to a full and complete stop. Many close calls of not being able to stop quickly on the highway or going down hill. The problem has been reproduced by the dealership. No warning messaging.

The Tucson Hybrid has died on the highway multiple times. Seems to happen on long drives the dealer has not reproduced this yet but my car has been at the shop for over 60 days. Car will stop accelerating even when gas pedal is pressed to the floor. Does not seem to be switching from battery power to gas power. No warning messages. First started in April.

Engine failed to switch out of battery power and loses power on the highway. This has happened on two different days the first time I had 58,000 mile the second time after Hyundai said it had been repaired the car has 65,000 mile. Both times my car went from 60 mph to 30 mph quickly. The last time I was in a construction zone and unable to get off the road and was only driving at 10 mph on a very busy highway. The car has been at the Hyundai shop since June. No there were no warning lamps, or messages.

The contact owns a 2022 Hyundai Tucson equipped with Michelin Tires, Tire Line: Primacy A/S Acoustic. Tire Size: 235/55/R19, DOT Number: (N/A). The contact stated that while driving at slow speeds, the vehicle began to wobble erratically, prompting the contact to pull over to the shoulder of the roadway. No warning lights were illuminated. The vehicle was taken to the dealer, who determined that the steel belts had separated from the tire wall on the front tires. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The tires were original equipment. The failure mileage was 20,000.

The contact owns a 2022 Hyundai Tucson Hybrid. The contact stated while driving approximately 15 MPH, the accelerator pedal was depressed; however, the gasoline motor failed to activate. The contact stated that the vehicle remained in EV mode and was not gaining forward momentum. The contact observed that the battery gauge needle was on the low end of the battery charge. The contact stated that the "PHEV battery assist lock" was illuminated. The contact stopped the vehicle turned off and restarted the vehicle and the normal engine function returned. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle was not diagnosed and was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 68,000.

While driving over 50 mph the emergency brake has initiated 3 times in a 4 month period. There are no cars in front of my vehicle and it is not the collision warning but it will flash on the dash the the emergency brake is engaged in red, it will make a warning beeping noise and the car will brake on its own.

Car lunched from a traveling in traffic 50+ mph to 39 mph and then had to push the pedal to the floor to get it off the highway and on the side during 5 o'clock traffic. Said something about the hybrid battery and went dead. Dealer has had it for 11 days and still can't get it started. Apparently there are THREE batteries in relation to this hybrid and all 3 don't work and never seen this before. Since it's been at the dealer, hyundai has emailed me no less than 3 times that I need to check my lights because my battery is getting low all the while it has been completely dead and they don't even know it. Suffice to say, there was NO WARNING other than a couple of miles prior, my car lunched down to the 39 mph and I lunged on the gas and it picked back up again but it wouldn't do it a 2d time. They obviously still don't know about the vehicle being so dead 2 different tow trucks had to be called because even the tires were locked up. Just still receiving my messages I need to check my lights because my battery (NOT BATTERIES MULTIPLE) is low and it's not low, THEYRE ALL 3 DEAD. I was in a dangerous situation and always felt safe in a 2 yr old car with a full tank and hybrid battery backup and less than. 20k miles. IF EVER FIXED because service may have to send OUT OF STATE I will never buy a hyandai or hybrid again. The entire battery system broke down. Which killed the entire electrical system which now no one knows how to fix

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.
