Owner report 11522976 · 2023-05-20 (May 20, 2023)

My son was backing out of a parking spot at a strip mall. He released some pressure on the brake and indicated that the car lurched backwards and even though he reapplied full pressure to the brakes, he hit the car at the curb resulting in damage to our Tucson, but luckily not the to the other car. The Rear Cross-Traffic Collision-Avoidance Assist system did not engage, but my son indicated that the rear distance warning system did beep. I am concerned due to the sudden acceleration/lurching incident my son experienced and this is not acceptab…

Owner report 11550615 · 2023-10-18 (October 18, 2023)

While driving the vehicle, the acceleration stopped and the car came to a halt right in the middle of the road. It acted like the battery drained and the gas did not kick in. The only fix was to shut it off and turn it back on. Took it to dealership they said they couldn’t find anything wrong with it so we picked up the car and as soon as we drove off, it happened again. This could result in a fatality if it happens on a busy highway since there is no warning and it just stops working. Took it back and the dealer says they can’t find anything w…

Two times in the last two weeks of March and about 10 times since we purchased the vehicle new in December 2022, after starting the vehicle and backing out of our garage onto our street, then stopping then shifting from reverse to drive and going no faster than 15-20 mph for about 300 yards, the Tucson revs up to about 3ooo-3500 rpm and will not shift into second gear. After about 1 minute or so it seems ok. But until then the transmission does not shift smoothly like it did the first six weeks of ownership. It did not operate like this until a…

I am reporting a critical Exhaust Gas Recirculation (EGR) valve failure on my 2023 Hyundai Tucson Hybrid. The failure resulted in an immediate loss of engine power, reduced vehicle performance, reduced fuel efficiency, and the vehicle entering limp mode while driving, creating a significant safety hazard in traffic.

Owner report 11622083 · 2024-10-26 (October 26, 2024)

While traveling out of town, our 2023 Tuscon HEV with 31,000k started chugging/hesitating during acceleration. This chugging continued to worsen, so we took it to a Hyundai dealership to diagnose. We were told that fuel injector #3 was misfiring, and, as they did not have the parts in stock, that it would be safe to make the 5 hour drive back home to service the vehicle. During the first 4 hours of the drive the chugging/hesitating worsened, several times suddenly losing power and speed dropping from 70 or so mpg, to 40 mpg and lower, creatin…

Electrical System	2623.2% ODI 11466122 The backup alarm sound is unreasonably loud. I understand that it's a Hybrid Vehicle and can be quiet but very few ICE vehicle are as loud as the backup sound on my vehicle. One impact of the loud sound is that I find myself rushing to backup just to be able to get my vehicle out of reverse so that alarm can shut off. This is especially true when I'm in trying to avoid noise. This can be backing into my own driveway if I come home late at night so not to wake the family or neighbors.

He was inches away from my rear bumper, riding me. When I put the turn signal to move away from him he hit my driver’s side rear panel (side swiped), thank God it didn't turn into a pit maneuver and killed us. He then proceeded to take off.

In order to meet the fed reg requiring the vehicle to emit a sound that reaches the 56 db level 6 feet from the rear bumper- Hyundai installs a >90db speaker in the front of the car. This design decision saved money and meets the standard but at a tremendous cost to those who happen to be in front of the car when it's in reverse.

It could not be moved (it was stuck in reverse) nor could it be shifted into neutral to be pushed out of the roadway. THIS WAS AN IMMEDIATE HAZARD. The car needed to be towed to the dealer.

I took in into the Hyundai Joplin, MO dealership on May 2, 2024. They could not find any thrown codes and suggested it was most likely the "IEB Module" which they replaced and after doing so, the warning lights remained activated. As of May 22, 2024, they are ordering a new IEB Module to install (backordered into June). This seems oddly similar to previous ABS and brake problems of earlier models and makes me feel uneasy with the safety of this vehicle should they ever get it remedied.

The tachometer shows the RPMs are maxed out, but the vehicle does not accelerate no matter how hard I press the gas pedal. I have to pull off the road, turn off the vehicle, and restart to fix it.

As I was (very slowly) pulling into a parking place at a park near my home and I was braking to come to a full stop, the car suddenly lurched forward, jumped the parking place barrier, and hit a tree. The front end of the car was badly damaged and the airbag opened. I sustained injuries to my left hand and my chest, though nothing was broken. The car was towed to a body shop, where it has been declared not reparable. Photos of the car at the scene are attached. This accident seems to be consistent with reports/recalls of the Hyundai Elantr…

On June 3, 2025, I experienced a terrifying and dangerous incident while driving my 2023 Hyundai Tucson Hybrid on a three-lane road at approximately 50 mph. Without any warning, the gas pedal became completely unresponsive, and the car abruptly decelerated from 50 to 20 mph. This sudden loss of acceleration was incredibly frightening, especially with vehicles close behind me that nearly collided with mine. There were no warning lights or check engine alerts. Fortunately, I was able to safely cross all lanes and pull over before having the vehic…
