In 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.

Over the past two months, I have had the yellow engine light come on. Even though there were no issues related to performance noted, I took vehicle to my garage to diagnose. The diagnosis did not find any issue, but mechanic proceeded to check the gas cover cap. Lo and behold, both times, removing the cap and replacing seemed to correct the issue and the yellow engine light went off. Quite annoying as don't want to have to keep checking if light comes on incorrectly and not address if there was indeed a problem to correct.
