2022 Hyundai Tucson Hybrid

Hyundai has a service bulletin for their 12V battery but isn’t notifying owners. Today my vehicle stopped working and lost all acceleration on a busy 3 lane street that is 55mph. I was able to limp it to a left turn lane where I had to research the issue and found many others had instances like mine. The battery stops working and subsequently stops the vehicle from accelerating and tells you to ‘stop safely’ with no warning or indication that you’re about to stop moving on a road.

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.

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.

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

While driving on busy highway the vehicle would not accelerate even with more gas applied. Gave warning to check hybrid system and pull to safety. Vehicle wouldn’t turn off after pulling over and in park with flashers on. Various warning lights all came on, gave message of battery discharge warning, check brakes, check ABS, check brakes then everything complete shut off including hazard lights. Wouldn’t start after that until jumped by tow driver. This is the second time this occurred, first time being within the first year after purchase.

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.

Case Synopsis: My ownership includes three Hyundai Hybrid vehicles: two 2020 Sonata Hybrids and one 2022 Tucson Hybrid. Each car has consistently manifested engineering defects, predominantly overheating, within a year of purchase. These persistent malfunctions have led to the vehicles being inoperable and beyond repair. As a result, we have endured financial setbacks from negative equity, costs of repairs, reduced value of the cars, and considerable inconvenience and safety hazards due to these ongoing overheating issues.

The contact owns a 2022 Hyundai Tucson Hybrid. The contact stated while driving approximately 45 MPH, the vehicle independently decelerated to 20 MPH with the RPMs falling and the vehicle almost stalling. There was no warning light illuminated. The contact stated that the vehicle failed to exceed 20 MPH. The contact pulled over to the side of the roadway, turned off the vehicle, and waited for approximately 5 minutes. The vehicle was restarted and operated normally. The vehicle was taken to the dealer however, the cause of the failure could not be determined. The vehicle had not been repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 25,714.

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
