2022 Hyundai Tucson power train problems

“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…”

“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.”

“Multiple DTC codes on car at 25,120 miles,32,344, 34,324, 47,484, 51,853, 53,521, Consistent Fuel Injector failing under warranty, prior to 60,000 miles and not replaced correctly, as I have had to see dealership 4 times for ineffective fuel injector replacement and consistent problem. First DTC code reading @ 25,120 miles as stated on DTC coding Reports through Hyundai/Bluelink app. SEVERE Fuel leak into interior cabin and Fuel failure due to Powertrain/Injector Issues from 25,120 miles, and many more mileage as seen above.

Caused car to engine fail in middle of driving!! *SAFETY CONCERN. I Have started multiple cases with Hyundai Motor America, and they had done nothing to report the problem or keep car for further testing and safety priority. 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…”

“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.”

“I am dealing with this issue where I am getting fuel injector issue and getting cylinder 3 misfire and air fuel imbalance code. It comes and goes. I spent 1500 bucks flushing fuel system and replacing spark plugs and coil. But the issue is still there! i changed the battery and got it to dealership they said they could find the issue. I was on freeway going southbound near exit 34 when the car starts shaking and I lost acceleration”
