Vehicle Fuel Injector code P053F84 Reading on 9/9/26, this is the second time vehicle was taken to the dealership for the exact same problem, the idle button in orange, and displayed, first visit while vehicle within warranty limits technician stated couldn't find anything wrong, now vehicle is out of warranty and dealership wants $1300 to fix the same issue.also the Engine was hesitating at each occurrence.

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 driveway. I also had difficulty getting the vehicle to brake and almost hit our community entrance/exit gate. A notification appeared on my infotainment system stating: “A possible condition with your Engine Control System has been detected. A full system check is recommended to be done soon. Please contact your local dealership to schedule an appointment”. The DTC codes listed on the Hyundai app were: PO30020, PO30040, PO30010, PO30000, and PO19185, P217700. (DTC system powertrain and subsystem EMS). I had the vehicle towed to the dealership. They didn’t have a loaner vehicle and I canceled my trip. Later, I was notified that “a hose was disconnected and was allowing air to enter the engine”. He stated, “we flushed it out and everything is working now”. I was told I could come pick it up before they closed.

The dealer was made aware of the failure and advised the contact to report the failure to the NHTSA Hotline.

The contact owns a 2022 Hyundai Tucson. The contact stated that the check engine warning light illuminated and was cleared; however, the warning light returned hours or days later. The dealer had cleared the check engine warning light approximately 15-16 times. The vehicle occasionally stalled while driving at various speeds. The dealer diagnosed the vehicle with terminal engine failure. The contact was informed that the fuel system needed to be overhauled, and the fuel injectors and caps needed to be replaced. 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. The following day, the vehicle failed to start approximately four times. The vehicle was driven to the dealer but hesitated several times along the way and failed to start once at the dealer.

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 unable to maintain speed or accelerate while traveling at highway speeds. This issue has significantly affected the safe operation of the vehicle. I request that this matter be investigated, as it appears to be a recurring safety-related defect.

Caused car to engine fail in middle of driving!! *SAFETY CONCERN.

Car is brand new, has about 66,800 miles on it now, had to replace all FUEL INJECTORS, FUEL RAIL, and now needing to replace Catalytic Converter due to Hyundai not covering issue that was consistent with Fuel Injector and initial GAS leak into Cabin. I had to visit the doctor many times due to GAS FUMES. 2025-2026-DTC codes stated under individual mechanic, and within my Hyundai Blue Link app as reading multiple DTC codes that Hyundai Refused to cover or fix initially.

The rocker arm of the engine has failed, causing a repair for a full engine replacement. The car has always undergone maintenance timely, and upon inspection by the dealership technician, the report state the vehicle was up to adequate level. There were no symptoms before the issue occurred, only the sudden catastrophic engine failure.
