What 25 owners told NHTSA about the 2022 Hyundai Santa Fe Plug-in Hybrid

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.

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.

My Vehicle Hyundai Santafe Plugin hybrid 2022 is not showing an accurate gas miles range. It is giving incorrect information especially when traveling long drives. This is giving me anxiety about the loss of gas in the vehicle. It is also does not giving approximate mileage as described by the company on the sticker.

New vehicle purchased 10/15/21 form Lester Glen Hyundai in Toms River NJ. After two weeks and 1100 miles car started leaking gasoline on garage floor, street and driveway at rate of approx one drop every two seconds. Called closest Hyundai dealer (Burns Hyundai), both dealerships said appointments were three weeks out, scheduled on 12/1 with Burns. Stated this was a hazerdous waste spill and extremem safety hazzard but dealers made no other offer of help. Before filing complaint called Hyundai corp and they told me they would escalate but would take 7 days to get back to me (Hyundai complaint #189991007). no one has called me. In last effort LM with president of Lester Glenn 11/18 at 3:20pm asking to call back and resolve so I would not have to file complaint, nobody called me as of 11/19 at 1pm. Leaking appears to be coming from a While plastic block at the rear of the gas tank.
