2022 Hyundai Santa Fe PLUG-IN Hybrid

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.

I have taken my Hyundai Santa Fe 2022 PHEV under warranty for a fix of being in reverse, the function not working, the car revs aggressively not in gear and then put it in park and the car aggressively jolts forward in park like a hard gear change. Hyundai replaced pcm and said it was fine. I took car and immediately noticed grinding noises and straight back to Hyundai. They claim it's fine. Today same issue with reversing and aggressive car jolting. Hyundai is going to take it back tomorrow. I do not feel safe in this vehicle. It felt like the transmission was going to give out on the freeway. The rpm are maxing out at 5-20 mph and sometimes don't want to engage in drive. Extremely unsafe for freeway driving. There is something terribly wrong with this cars engine or transmission. Unsafe for Hyundai to release for use.

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.
