2022 HYUNDAI TUCSON HYBRID Complaints

Car is a Gas Hybrid (not plugin). 3 occurrences over the last couple of months. Car emits a warning sound and a message on the dash says "Check Hybrid System. Stop Safely". Basically right after this message the car starts losing power and stops. Doesn't matter if on freeway or not. You need to find a place to pull over or you stop traffic wherever you are. Looks like Hybrid Battery is completely drained. Can not be re-created. Dealer has it now for the 3rd time. Dealer in the past have not been able to find cause/cure since this issue is not posting any errors to the onboard diagnostic system. Temporary 'fix' is to power off car, and power back on. Looks like this is a 'known' issue though as its being reported by quite a few people online.

Repeat Repair Timeline – Loss of Acceleration Vehicle: 2022 Hyundai Tucson Hybrid Blue Issue: Intermittent loss of acceleration from a complete stop (safety concern) Occurrence 1 Approx. Date: 12/2025 Mileage: ~ 48000 Description: Vehicle failed to accelerate immediately after a complete stop. Pressed accelerator and experienced a noticeable delay before the vehicle moved. No warning lights. Turned on and off. Restarted normal. Action Taken: No service visit at this time. Occurrence 2 Approx. Date: 01/2025 Mileage: 12/2025 Description: Same issue occurred again from a complete stop. Delay in acceleration while entering traffic. No dashboard warnings. Action Taken: Issue noted for future service visit. Occurrence 3 (Reported to Dealership) Date: 50,000-mile service 01/14/2025 Mileage: ~50,000 miles Description: Loss of acceleration from a stop occurred multiple times prior to this visit. I informed the dealership that this was a very dangerous safety issue. Dealership Response: Vehicle was serviced as part of the 50,000-mile maintenance. Dealership stated they could not find anything wrong. No specific repair or explanation provided. Outcome: Issue was not resolved. Occurrence 4 (Post-Service) Date: January 28, 2026 Mileage: ~55,999 miles Description: After coming to a complete stop, I pressed the accelerator and the vehicle did not respond for several seconds. No warning lights or alerts. This occurred after the dealership stated no issue was found. This condition has resulted in a dangerous delay while entering traffic and creates an immediate and ongoing safety risk to the myself and young children passengers, and surrounding vehicles. The defect involves a loss of acceleration / loss of motive power and has occurred repeatedly without warning. I am formally requesting escalation beyond the dealership level, full documentation of this safety defect, and a permanent corrective resolution. It is not safe.

I was almost going to hit the vehicle on high way i decreased the speed according to front of my car but controller not responding speed didn't decreased I suddenly realized that slammed on break. Nothing was happened i already sent email to hyundai but no respond. I looks defective controller switch. Now other side of steering volume control switch also becomes loose

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.

While driving the engine would not turn on and we were stuck EV MODE. Lost power , had to pull off to shoulder of road and had to turn vehicle off and back on in order for car to move.

All warning lights and audible alarms started going off at the same time. EPS, ABS, Auto Hold, Collision warning, Air bags, All wheel drive, brake system, and more.1st time it happened was [XXX], while driving. The car was drivable but I did notice a difference in braking and acceleration. I parked and turned off the car. I did turn the car back on several times and the alarms continued. I finally turned it off for 10 min, and all alarms stopped, but the check engine light stayed on. Car sat overnight and all warnings had stopped. Took it in for service, and issue could not be duplicated. 2nd time it happened was [XXX]. I had to have the car towed since it would not move when in drive or reverse. Alarms were still going off when it made it to service. They replaced the brake harness. 3rd time happened on [XXX], 3 days after the brake harness was replaced. Towed it to service and they replaced the engine harness. 4th time was on [XXX], 2 weeks after engine harness was replaced. This time there were no audible alarms, just all of the visual ones. Same performance issues as stated before. This issue seems to have happened to several other Hyundai owners as well, as per complaints in Reddit and on Hyundai forums. There does not seem to be a consensus for what is actually causing this issue. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving, my entire dashboard lit up with every warning sound and symbol for the car. It would cycle through collision, airbags, braking, all of it. Luckily I was able to drive to a safe place. I let the car sit overnight and the alarms stopped. Took it to service and they could not recreate it and no codes showed up. Second time it happened, the warning sounds and lights didn’t stop. The car would jerk when I tried to put it in drive, so I had it towed to dealership. They have video and photos of it. After 2 weeks, they said it was fixed-a pin in a connector was bent. Had car for 3 days and it happened again. Had it towed again. They have had their ‘senior’ techs looking at it, and none can figure it out. There are Reddit posts with this same issue, as well as Hyundai group sites.

The blind spot warning went off and locked all the brakes up. We were not able to move the vehicle and could not even pull off the road out of traffic. There is no way to disable the brakes when the computer or sensors are malfunctioning. We had to get the vehicle towed.

The car has had a check engine light on for a week. It sometimes jolts forward when pressing on the accelerator and it does it all of a sudden. Took it to the Hyundai dealership they say it’s due to the egr valve and sub harness.

I wasn’t even allowed to select all the issues I’ve had with this vehicle since day of purchase three years ago June, and upon picking up the car I have had issues. My leather seats have bubbled up. My car will not merge. It will suddenly accelerate my car drops down in the middle of the road. My moonroof opens on its own. My car windows were randomly roll down on its own. My car breaks itself. My car emergency brake won’t unhook my car. Every single light is now on it. They have attempted to fix numerous times and my life has been put in jeopardy and my child’s life numerous times. No one can fix this issue. I am now told her I will have to wait three weeks for a rental because everyone’s backed up in diagnosing these cars. This car is going to kill me in my child and is a safety hazard. It does this stuff with lights on and without and it’s random and no warning my EV warning has come on my brake system. Warning has come on my car has been unable to stop and coasted and suddenly was able to then stop.
