2022 Hyundai Tucson transmission problems

Filed Sep 30, 2026 · Transmission · RI

On three occasions my car suddenly stopped transferring power by not accelerating when the gas pedal was pressed. The first time the engine light came on and when I brought it for service they said it was a sensor covered by warranty and repaired it. The second time it happened while I was trying to merge with traffic on the highway. I took an exit and managed to get to the dealer. They replaced the fuel injector and fuel line. The third time, first the car struggled to start after work. Then, I was pulling out of the parking lot, crossing a very busy road. The car could barely get up to and past 20 mph. Once I got it to 35 or so, I stayed on local roads with my hazards on, and managed to get it to the dealer. No engine light came on and they haven’t been able to replicate the issue. This is a very serious safety concern! I am afraid to drive it now since the car can stop without warning and without any brake lights coming on. I am fully covered by warranty but am worried they won’t want to cover the cost to make my vehicle safe. Google shows engine problems like this as one of the known issues on the 2022 Tucson Limited.

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.

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.

Bought the 2022 Hyundai Tucson. It was driving perfect no issues then I hit 52,000 miles and the check engine light illuminated. The vehicle started sputtering and idling hard like it wasn’t getting fuel when the gas was pressed. I was on the interstate and the vehicle wouldn’t go over 35mph. Now the check engine light illuminates off and on when it feels like it.

When My wife was driving our car on the highway today to work, the car suddenly threw a "check hybrid system - pullover safely" light when she was at highway speeds. She was able to luckily pull over quickly onto the shoulder before the car completely powered down. This is incredibly dangerous. She had to click on the reset 12 volt hybrid battery button in the car to get it started again but the complete loss of power at highway speed was very upsetting.

I am submitting this complaint due to a potential safety-related engine failure that occurred while my vehicle was under dealership repair. My vehicle was dropped off at Huffines Hyundai on October 2, 2025, for a fuel injector issue and has remained under the dealership’s exclusive possession since that date. I have not driven or had access to the vehicle after drop-off. During the repair process, I was informed by dealership staff that an injector was seized in the fuel rail and difficult to remove. Although the injector replacement was documented as a short repair, the work was delayed and completed on October 16, 2025. Immediately following this repair, on October 17, 2025, the engine was documented by the dealership as having low compression. I was not notified of this condition until October 27, 2025. The engine damage occurred while the vehicle was under dealership control and immediately following a repair involving seized components. The diagnostic documentation provided to me is incomplete and does not include compression PSI values or supporting data. I am concerned that improper repair or handling may have caused internal engine damage, resulting in a condition that could lead to engine failure or unsafe operation. Due to the circumstances and lack of transparency, I do not feel the vehicle is safe to operate and am concerned about the risk of engine failure.
