2022 Hyundai Santa Fe Plug-in Hybrid problems

“The car was shaking alot but the engine light was off. Started it the next dat and the check engine light came on. Went to auto zone to see what the codes were. The 1st and 3rd cylinder are misfiring. The car was just serviced for the 60,000 mile tune up in june 2026. This problem started August 14, 2026. The dealership is stating that the spark coils or cylinders are not under warranty even though it was just serviced”

“First the vehicle randomly lost all power and engine function, so was taken to the Hyundai service center. It was a safety issue as we had to coast to the margin in heavy traffic. Hyundai attempted a fix and returned it to us. It developed issues before we even got home. Now it is has been 6 months in the service center with continuously new issues. Every time they assure us it is fixed and we try to take it home, it develops another failure and the check engine light returns. The technicians have told us they have no explanation for the multiple failures and are not confident they can permanently fix the vehicle. The failures are unrelated and are with the manifold, gasket, CVVD,, oxygen sensor, and battery. A bolt also sheared off in this time frame and had to be drilled out. In the last failure, the car began smoking heavily and dripping oil. We've requested a replacement. Hyundai said they will not replace the vehicle (nor buy back) and it is acceptable that multiple systems and parts fail within 3 years.”

“Loss of acceleration while driving. This has occurred multiple times (always while moving or actively driving). The first time we were driving up a significant hill and the car slowed, lost power and we had to pull over and coast back down the mountain to a repair center. The second time, I was on the freeway and lost acceleration causing me to pull off the road in median. The third time, I was at a stoplight and when the light turned green, I had almost no movement after edging into the intersection. Eventually, at about 5 mph, the car regained speed. The check light went on in the first event and the car was supposedly repaired at the second dealership by re-tensioning "pins". However, no lights or warnings went on for incident #2 or #3 that occurred after the earlier repair effort. The vehicle is currently at the dealership service center for it's 7th day of "unable to replicate the problem" after incident #3.”

“From park to Drive or reverse there’s an issues with changing in between doing so. Loud noise and shake to the car when engaging in the new gear. Then it sounds like the cars accelerating but parked, not moving. When you put it back in drive a loud thud then revving noise occurs. Once driving again just after there’s little to no movement when you put your foot on the pedal. When you drive it’s slow to go. You can hear the car trying but you’re hit going the same pace as the other cars on the road. Seems unsafe. This has happened more than once. I mentioned it to the delayer they said it was fine. No issues.”

“The steering wheeled locked up and the dash showed error messages of check hybrid system and refill inverter coolant and car seemed to go into limp mode as I could barely accelerate forcing me to pull over. The messages and issue would go away upon turning off car and turning it back on, however the issue would eventually happen again. This has happened while driving on the highway and other various road situations without warning and making the vehicle very unsafe. I have taken my vehicle to Hyundai Ourisman in Bowie, Maryland (the dealership where I purchased the vehicle) three times over two years and they have failed to fix the problem. They have even replaced the battery in the car.”

“I was driving on a road approaching a right turn to enter into my neighborhood that has a 3 way intersection where only cars exiting the neighborhood have a stop sign. I turned my right turn signal on as I began to slow down and approach the turn (without stopping as there is no stop sign for my path). As I was about 1/4 way into the turn, an alert for either lane keep assist or driver assistance warning appeared and the steering wheel suddenly could not turn and I was forced to drive straight. Luckily, there was no car waiting at the stop sign or I would have hit them. I hit the brakes and was on the wrong side of the road pointed towards the curb. I saw multiple error messages for lane keep assist and drivers assisted warning but could still not turn the wheel. I slowly drove the car forward, wrestling the wheel to turn enough so I could park on the wrong side of the road. I tried putting the car in park and then drive again but it did not help. I turned the car off and on and the errors cleared and I could turn the wheels again. I then proceeded to slowly start driving home and less than 1/4 mile later as I was rounding a gentle curve (I did not use any turn…”
