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

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.

I was idling for 15 minutes and then drove for 10 minutes at which time the Check Hybrid System Stop Safely alert showed on my dashboard with the red light. I was on a bridge and could not stop in the middle, this was very terrifying and dangerous as I was loosing acceleration and speed and it felt like the car was about to totally turn off, i was losing control, I was pressing on the brake and i felt it was not braking at which I point luckily I was at the end of the bridge and pulled aside, and turned it off. I waited 15 minutes before turning it back on and drove it back home. As I was driving it I can see the battery level rising. I plugged the charger that night to charge it and it started charging but then suddenly stopped and would not charge. Since then I tried charging it again and it charges for an hour and stops. I took it the dealer at the earliest appointment I can get and they ran diagnostics and no code came up. They said that it had to do with the coolant and they put in a new coolant and that should hopefully solve the charging issue. I tried again to charge it at home and again it charged for an hour and then it stopped and will not charge again. I am scared to drive it far now and especially on brides.

The accident took place on February 13 at approximately 7:40 a.m. My wife (the primary driver of the vehicle) had just dropped my son off at school and was pulling the vehicle into our garage as she has done at least four times a day since we purchased it in February 2022 for use as our primary family vehicle. She pulled into the garage, came to a complete stop, pressed the “Park” button and confirmed that the vehicle was in park, and removed her foot from the brake. The vehicle then lurched forward and collided with a storage cube adjacent to our garage wall, causing extensive damage to both the front end of the vehicle and the garage/dining room wall. Within minutes of the accident, I contacted Temecula Hyundai (our local dealership and service center), informed the Service Manager of what had just happened, and asked them how they wanted me to proceed given the fact that the malfunction was a warranty issue. They directed me to handle the accident through my insurance company. I specifically asked whether the vehicle needed to be preserved in place and not driven in order to maintain the scene and/or vehicle for investigation, and they said no. Nevertheless, we brought the vehicle to Hyundai that day to have it inspected and computer diagnostics run, since I suspected both might be necessary. They said the computer likely wouldn't capture this type of issue. We waited several weeks for our assigned Hyundai Case Manage (Tracy) to contact us with further instructions (which never happened, despite several requests for her and/or a supervisor to contact me), but eventually followed our insurance company’s instructions to take the vehicle to Caliber Collision to proceed with repairs, which were completed on March 30. We are still waiting for Hyundai corporate to address the issue.
