Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“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. Diagnostic & Technical Details: Error Codes Captured: Diagnostic trouble codes in the P0400 series (EGR system flow/circuit malfunction) were confirmed during diagnostic inspection. …”

“The ABS, ! Brake and Auto Hold lights activated. 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.”

“Unknown what fails. After driving approximately 30 minutes on a highway, car suddenly stops accelerating and bucks a bit as it slows. Must turn off car and turn it back on to accelerate again. Happens on the highway frequently. Very dangerous as there’s no way to accelerate. Only stop. It’s like it can’t find a gear and the engine revs. It happened 6 times during a 2.5 hour drive.”

NHTSA complaint #11527493, filed 2023-06

“1. Sometimes vehicle does not start. Only starts if battery reset button pushed. 2. Sometimes vehicle while moving has delayed braking after juddering. Only stops when car stopped and restarted. 3. Sometimes vehicle while moving suddenly revs, RPMs spike until car stopped and restarted. Engine revs but does not shoot forward. 4. Spookiest of all, while moving car suddenly stops accelerating. Pedal on the floor and it is coasting to a stop. When car stopped, and turned off, then it will work. …”
