Open Ticket with Hyundai #21018148 while car at the dealers for weeks at the time. each time told check engine got back on but not the message they are looking for.
NHTSA complaint 11514685While driving the hybrid system warning light comes on and says to check hybrid system, vehicle goes into limp mode will not accelerate over 25 mph and codes need to be cleared before vehicle van be driven. This has caused me to almost have several accidents. The vehicle slows down and gives no warning prior to this occurring. It has started happening more frequently vehicle currently has 85k miles.
NHTSA complaint 11500417The contact owns a 2016 Hyundai Sonata Plug-In Hybrid. The contact stated while driving 70 MPH or faster in Hybrid Mode, the vehicle stalled. The HEV error warning light was displayed on the instrument panel. The check engine warning light was also illuminated. The contact turned off the vehicle and disengaged the HEV Mode for the vehicle to restart and function as intended. The failure occurred three times. The vehicle had been taken to the dealer however, the mechanics were unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was made aware of the failure and opened a case. The approximate failure mileage was 66,000.
NHTSA complaint 11490124My 2016 plug in hybrid Sonata repeatedly inidcates that there is "high system temperature switching to hybrid mode." This first happened on my first long trip in the car in 10/21 and has happened repeatedly since. This happens at all temperatures, including moderate temperatures (mid 70s). It seems to happen randomly, such as when battery has several miles of charge left in it, when it is fully discharged, and repeatedly when the car is already running in hybrid mode, which a driver could interpret means that the engine is about to shut down, as I did on a long trip. I have taken it to two separate dealers, and the only thing they did was replace the fuel pump, which did not solve the problem. In addition, the battery life has reduced greatly, despite the fact that I always fully discharge and recharge the batter. As you can see from the attached Hyundai forum comments, this appears to be a prevalent problem for this make and model car and no relief from the manufacturer appears to be on the horizon.
NHTSA complaint 11478763The contact owns a 2016 Hyundai Sonata Plug-In Hybrid. The contact stated while the vehicle was approaching a stop sign, the vehicle stalled. The contact stated there was no warning light illuminated. The vehicle was not drivable. The contact stated he manually pushed the vehicle to the side of the roadway. The contact went back with his trailer and trailered the vehicle to the local dealer where it was diagnosed with needing the Hybrid control unit to be replaced. The vehicle was not repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 120,000.
NHTSA complaint 11472475In January of 2022, my vehicle experienced a complete power loss while driving to work, leaving the car coasting down the road. A Check Hybrid System warning came up on the dashboard, along with several other warning lights, including Check Engine. Luckily, I was able to pull over without an accident occurring. Once stopped, the vehicle did restart and got me to and back from work. A diagnosis effort made at a local Hyundai dealership was unsuccessful as they could not replicate the problem and found no error codes in the auto's CPU system. I continued to drive the vehicle, hoping it was a one time deal, but since then, the identical situation has occurred three more times. I was extremely lucky that I had been in a position to safely pull off to the side of the road. The car has not been driven since March 19, 2022. After researching this scenario online, it appears to be the exact situation reflected in the Hyundai Recall campaign 175 from 2018, where the dealership remove the original VPD module and replace it with a Battery Management System (BMS) that contains an Overvoltage Protection Device (OPD). The recall is said to have been done on my vehicle, but the exact situation has reoccurred. Every time time the car lost power, it was preceded by a shuttering feel in the car, an alarm would go off and the propulsion system would just shut down and the Check Hybrid light would come on. Hyundai's only response has been to drive the car until it fails again (can you believe that?) and bring it in again for diagnosis. Even if that were to be done, the technicians and others on the road, would then be put at risk, as well, if they drove the vehicle in an attempt to get it to fail. I am the second owner of this car and the recall was supposedly done prior to my purchase. I now wonder if the dealer knew of the problem and that is why it was $2K below KBB. I cannot safely drive the car and can't sell it without loss once this safety issue is revealed. Thank you.
NHTSA complaint 11461197This is a plug-in hybrid. Charging light on the dash blinks red indicating there is an issue (per manual). Also blinks while driving. Should be green. Still charges. Taken to two Hyundai dealerships. Computer produces no codes. Dealership does not know how to proceed. Safety concern is it’s unknown if battery is dangerous to charge? Is it dangerous to drive? How does a car indicate a problem but then give no codes.

HYUNDAI CLAIMED TO HAVE FIXED THE PROBLEM THREE TIMES SO FAR BUT IT KEEPS HAPPENING AND SINCE THEY ARE UNABLE TO REPAIR IT UNDER WARRANTY, THEY MUST BUY THE CAR BACK. ONE OUT OF THE FOUR TIMES, THE CAR COMPLETELY DIED ON THE ROAD PUTTING LIVES ON THE LINE. A COMPLAINT WAS FILED EARLIER (REF: HYUNDAI CASE #111109600, NHTSA COMPLAIN #11080680) BUT NO ACTIONS WERE TAKEN BY EITHER HYUNDAI OR NAHTSA. THIS CAR IS UNSAFE TO BE ON THE ROAD AND CAN NOT BE FIXED AFTER THREE TRIES WITHIN A YEAR.

NHTSA complaint 11084582WARNING LIGHT SAYING "CHECK HYBRID SYSTEM" COMES ON AND THE ENGINE WOULD NOT START IF THE CAR IS PARKED. WHILE DRIVING THE CAR COMPLETELY SHUTS OFF WITHOUT THE ABILITY TO PULL OVER AT A SAFE LOCATION. IT HAPPENED TO ME THREE TIMES SO FAR, TWICE UNDER 18,000 MILES AND ONCE AT 24,600 MILES. THE DEALER IS NOT SURE WHAT IS CAUSING IT AND GIVES IT BACK TO ME AFTER SOME TWEAKING TO GET RID OF THE WARNING LIGHT. I HAVE FILED A COMPLAIN WITH HYUNDAI (CASE # 11109600) REGARDING THIS. THIS CAR IS A DEATH TRAP AND I WILL NOT EITHER DRIVE OR RIDE IN THIS CAR EVER. I WILL NOT BE SATISFIED IN ANYTHING LESS THAN A COMPLETE BUY BACK. I AM ASKING NHTSA TO FORCE A RECALL AND HAVE THEM FIX THE PROBLEM WITH CONFIDENCE OR DO BUY BACKS. IT'S A DEATH TRAP AND CAN NOT BE ALLOWED TO EXIST ON THE ROAD.

NHTSA complaint 11061171WHILE DRIVING THE CAR AT 68 MPH IN HOV LANE, HYBRID SYSTEM ALERT LIGHT UP AND THE ENGINE COMPLETELY LOST POWER AND SHUT DOWN. VERY DANGEROUS SITUATION AND LUCKY ABLE TO DIRECT THE CAR TO RIGHT SIDE AND STOP AND WAIT FOR TOWING. THIS HAPPEN DURING TRAFFIC WAS SLIGHTLY JAM SO ABLE TO DRIVE TO THE RIGHT SIDE WHEN OTHER CARS ARE SLOWING DOWN IN REGULAR LANE. CANNOT IMAGINE IF THERE IS NO TRAFFIC JAM, HIGH POTENTIAL TO GET INTO ACCIDENT AND LIFE THREATENING SITUATION. WITH THE DEALER FOR FIVE DAYS AND THEY CANNOT PINPOINT THE EXACT PROBLEM AND KEEP ON SAYING IS SLIGHT PROBLEM. HOW CAN THIS BE SLIGHT PROBLEM WHEN THE ENGINE COMPLETELY SHUT DOWN?? NEED TO HAVE MAJOR RECALL FOR PUBLIC SAFETY. THERE ARE SIMILAR PROBLEMS FROM OTHER OWNERS THAT HAVE DISCUSSION ABOUT THIS SAME ISSUE ON THE INTERNET. I HOPE THIS WILL BE ADDRESS AND RECALL BEFORE SOMEONE GET INTO MAJOR INJURY OR LOST OF LIFE.
