“In April 2026 (29,805 miles) I was on an interstate underpass U-turn and when I went to accelerate from the U-turn, the vehicle “revved”, had difficulty accelerating, and appeared to not go into the next gear for a roughly 10 seconds, meaning I was unable to accelerate and get out of the way from oncoming traffic. Traffic slowed and the vehicle suddenly returned to normal (no warning lights appeared) and I drove home cautiously with hazards on. When attempting to leave less than 45 minutes later, the vehicle started, then as I placed it into drive, it began lunging and the check engine light appeared. Because it was running rough and kept lunging, I parked and had it towed to the dealership. The DTC code listed was PO30300 (DTC system powertrain and subsystem EMS). Per the dealership, fuel injector #3 was bad and needed to be replaced. When I picked up the vehicle, notes stated “ GDI FUEL INJCTR REPL (ALL4)”. I picked up the vehicle after the repair. In August 2026 (30,923 miles), with less than 1,000 miles driven since repair, I started the vehicle and it immediately “died”. I restarted it and the check engine light came on and it began lunging out of my…”

The vehicle was repaired twice. The failure persisted after the contact had confirmed the diagnosis with a certified mechanic. The vehicle was returned to the dealer, who replaced the engine. The vehicle was parked for several hours, and the contact attempted to turn on the headlights, but the headlights failed to illuminate. While driving the vehicle, the vehicle hesitated several times.

“My 2022 Hyundai Tucson Experience, a sudden transmission failure at approximately 92,520 miles. The vehicle develop shifting issues and abnormal noises before losing propulsión. While driving. Hyundai diagnosed and internal Transmission failure and approved transmission replacement. I’m concerned about the sudden loss of proportion and the safety risk this creates. Hyundai proposed repair is to replace the transmission with a rebuild remanufacture transmission rather than a new transmission. I am concerned about the reliability of the repair following a complete transmission failure.”

“I am submitting this complaint regarding my 2022 Hyundai Tucson equipped with the 2.5L engine. The vehicle has experienced multiple incidents of severe engine misfiring while driving. During these events, the engine begins to shake violently, the entire vehicle vibrates, and engine power is significantly reduced. The vehicle becomes unable to accelerate normally, creating a serious safety hazard, especially when driving on highways or in traffic. The malfunction has occurred several times. Diagnostic trouble codes P0302 and P0303 have been recorded, indicating cylinder misfires. In some cases, turning the engine off and restarting it temporarily restores normal operation. On other occasions, adding fuel system cleaner appeared to temporarily improve the condition. However, the problem eventually returns. Because the condition is intermittent, the Hyundai dealership has been unable to reproduce the failure during inspection and therefore has not performed a repair under warranty. Despite multiple visits, the root cause remains unidentified. I am concerned that the sudden loss of power and severe engine vibration could result in an accident if the vehicle is…”
