NHTSA Complaint #11478351 — 2018 HYUNDAI SONATA

For the fourth time the HEV light (and others) has come on and the dash has lit up while I was driving, with the last three times leaving us stranded in dangerous road situations with little or no power. The light first came on in July 2020 at 40,089 miles. A dealership reset the codes and I had no problems until June 7, 2022 when the lights lit up on the dash again and the car died and I had to have it towed to a local dealership. They could find nothing wrong with it and checked all the wiring and said none of the codes were coming up and that the car ran fine for them when test driving a day or two after I had it towed. So they released the car back to me deeming it good to go. Then only 19 days later on June 26, 2022 the HEV light among other lit up again and the dash indicated to pull over and cut the car off due to the hybrid system. I had it towed to the nearest dealership again. The then looked at it and said they reset all the codes and everything looked to be good to go. Then AGAIN on Aug 8, 2022 (3rd time in two months), we were put in a dangerous situation trying to get the car off a busy highway when the HEV light (and others) again lit up the dash and our power went almost completely out while the engine jerked violently as we tried to avoid being hit by cars while trying to get off the highway before it completely died on us. Four times now Hyundai dealers have shrugged this off saying "we reset the codes" and we can't find an issue. We have been put in dangerous traffic conditions three of these times.
