The contact owns a 2012 Hyundai Genesis. The contact stated while driving at approximately 35 MPH, the vehicle lost motive power, shut off but was able to coast off the highway. There were no warning lights illuminated. The vehicle was towed to the local dealer, where it was diagnosed that the electronic computer motherboard needed to be replaced. The vehicle was not repaired due to parts being on backorder. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 62,000.
Driver's side passenger door lock does not electronically function--either by key fob or by driver's control. Passenger door must be manually locked and unlocked. This defect was present from time car was purchased new but was only discovered after car was out-of-warranty since passenger door had never been used until grandchildren began using back seat. This represents an safety hazard in the event that back-seat passenger needs to exit car quickly via electronic means. We are aware that this defect is quite common among 2012 Hyundai Genesis owners. Hyundai Motors of America knows that this was a manufacturing design defect but thus far, is unwilling to support warranty repair. Warranty repair is quite costly, averaging $700-900, and this is likely the reason why HMA has elected to publicly hide and ignore the issue.
I am reporting an electrical problem w my 2012 hyundai Genesis. My back driver's side door lock just stopped working in 2021 & a few months later , my front passenger seat door locks also stopped working. I brought it in to the dealer this morning to have both locks checked. I know the back seat door lock is the actuator & im assuming that's the issue w the front one too. I'm waiting to hear back from the dealer what the problem is, but actuators on the 2012 genesis are defective or it's an electrical problem. No accidents happened bc of it, I was just told to report this issue.
While turning at low speeds, the vehicle will turn off completely. This kills all power steering and brakes. This has occurred on several occasions and is documented on the web and genesis forums by other Hyundai owners as well, so this is not an isolated case. There was no warning of any kind that the car would be shutting down. The problem has not been reproduced by the dealer and that is the problem....you never know when it's going to happen and is extremely dangerous.
The rear view camera continues to not work properly. The camera screen will either display a black or scrambled view or none at all. This happens periodically from month to month. When the screen becomes scrambled, it creates a major safety issue. If there was an person or object directly behind the car when backing up, you would not be able to see it. There are no warnings or notifications from the car when this happens.

Navigation display failure resulting in no back-up camera, no a/v functions, and HVAC control malfunction. Dealer replaced within approximately 8 months of purchase. System has failed again and corporate advised that the part was on backorder and we waited for a replacement part for 8 months. Now corporate has advised that the part, a-v monitor assembly part #965633m851, is unavailable/discontinued. No way to repair or replace the part. Vehicle has 44,000 miles on it. Sunroof failed within first 20,000 miles and was sealed to avoid expensive repair. Most recently the car died without warning while stationary. In for evaluation now. This car has been a chronic problem since we first purchased it and corporate has told us that we are at a dead end regarding the a/v monitor assembly - there is nothing they can do. A/v monitor assembly issue occurred in June of 2020.
