The vehicle has 2 permanent codes. One is a communication blackout, the other code means the hardware is melting. GM is doing a formal inspection in April. The Ucode meant that the engine stopped talking to the transmission or visa versa. The vehicle “ran my daughter and I” off the highway into the dirt, on 2 different occasions. They are described as “catastrophic engine failures”. The last one occurred on MLK Jr Day 2026, before the vehicle was permanently grounded. It could have been fatal. GM is doing a formal investigation to see what liability the have for it because the vehicle is now considered a “lemon”. There were no external (dashboard) warnings before the events, but, there may have been internal ones that require a professional grade scanner to detect. The permanent Ucode, which causes a communication blackout, never appeared in the vehicles memory, on a scanner, until AFTER the local GM franchise conducted “repairs” (unsuccessfully) to fix the vehicle. (It wouldnt start, which is often a symptom of a Permanent UCode. The GM investigation will determine if the dealership knew the safety liability, (the permanent Ucode) and they tried bypassing or ignoring it, or, if they CAUSED the safety defect. Also, the vehicle is now showing a Permanent PCode, which means it is now a potential fire hazard.
