What 2 owners told NHTSA about the 2023 Genesis Electrified G80

Our 2023 Genesis G80 electrified has been towed three times for the 12v battery or its electrical system. We have yet to drive the Genesis once. It is a safety danger which produces toxic smells in the interior and the trunk plastic gets hot to the touch. The interior was impregnated with the smell as the car was closed. Given the symptoms, the dealership refused to drive the vehicle for service and had it towed due to safety concerns. They attempted repairs three times, finding no error codes or answers the first two times. They returned the dangerous defective vehicle twice. On the third repair attempt, they stated the battery has a short circuit that is causing it to overheat to temperatures over 166 degrees. They also found the accelerator pedal and sensor assembly was out of specifications. Both were replaced, but they have been unsuccessful in getting the smoke/burnt smell out of the vehicle. It has saturated into all of the interior surfaces. Both are extreme concerns for fire risk as well as danger when driving since the accelerator pedal was not working as it should have been.

When using the I-Pedal feature the brake lights do not come on at any point when lifting off the accelerator pedal gradually. This certainly can cause the vehicle to rear ended if the following car is not paying attention. If you take your foot off the accelerator fully for full regeneration the brakes lights do come on. I was following my wife in her Genesis G80 EV and I noticed the brake lights not coming on. I did report it to both Genesis and the dealer but they did not know of any issue or could tell me when the brake lights should come on. This issue has been reported in the following article and it looks like it may be an issue with all the Hyundai Group EVs. https://apple.news/AyymCGI5gTlCa1ZeFW0jAxg
