2022 Hyundai Sonata Hybrid electrical complaints

Filed Oct 22, 2023 · Driver assistance, Electrical · MA

As I was driving my dashboard lit up with warning lights and audible alarms indicating that I should inspect my regen brake. Safety features such as lane departure, lane assist, blind spot indicator stopped functioning and my speedometer did not work. I stopped the car and looked behind the front wheels and nothing looked “unusual”. I restarted the car and all of the alarms went off again, leaving me without a speedometer or the safety features mentioned above. I scheduled an appointment with my dealership explaining what had happened. They did a diagnostic test and determined that it was a faulty E Brake Module that needed to be replaced but is on back order with no parts available in the US to order. Furthermore they do not know when a replacement is available. They reset the sensors so that my safety features were restored. This is the second time within a 14 months of purchasing the brand new vehicle that electrical systems have needed to be replaced. The first time was a faulty wiring harness located in the trunk area that the dealership had said “must have been damaged during installation at the factory”. Again-when I driving at highway speeds suddenly the alarms and warning lights were triggered-leaving me without the same safety features, speedometer and power steering/brakes. The dealership was able to replace the wiring harness and the problem seemed to be resolved until this latest incident.
