I was parking in the garage and only tapped on the gas to move a little bit forward and the car accelerated on its own into a racking system and that racking system went through the wall of our home.

My 2024 Cadillac LYRIQ, VIN [XXX], has a recurring 12V/electrical problem that has caused repeated battery failures and no-start conditions. At 4,716 miles, the vehicle would not start, the dash went black, and “Service Battery Fault” appeared. Cadillac tested the 12V battery, documented that it FAILED, and replaced it. Only 367 miles later, at 5,083 miles, the vehicle displayed “Electric Drive Unit Immediate Attention” and “Limiting Features to Save Battery.” Cadillac documented code U2C11 and performed BECM/Hybrid-EV Battery Pack Communication Module programming/reset. At 12,839 miles, Cadillac documented another electrical issue: the radio and display would not turn off after the vehicle

On or about August 6, 2026, I received email communication from the GM EV Concierge , establishing Case #106606137. My vehicle has been "bricked" and GM has had possession of it since August 3, 2026, (46 days and counting) without so much as an official diagnosis or repair timeline.

Regardless, the practical result remains undisputed: my vehicle continues to be unavailable, my vehicle

The vehicle is a Cadillac Lyriq. Following an over the air software update pushed by the manufacturer, the vehicle began displaying a high voltage system error message and lost the ability to DC fast charge. The high voltage components themselves are reported to be functional, the issue appears to be caused entirely by the software update rather than a hardware failure. The vehicle has been at an authorized dealership service center since August 14, 2026, awaiting a resolution. The dealership has confirmed the fault is present and is consistent with a known issue caused by the manufacturer's software update, but has not been able to repair it independently, since the fix requires a corrected

On August 9, 2026, at approximately 3:40 a.m., while driving, the vehicle suddenly lost all propulsion and became completely disabled on the roadway. The vehicle remained powered on but would not move forward or backward. At approximately the time of the failure, Cadillac/OnStar Advanced Diagnostics generated a critical Electric Drive Unit warning instructing immediate service and reported diagnostic code P0A78. Additional vehicle diagnostic warnings involved the electric drive unit/high-voltage propulsion system. I immediately contacted roadside assistance but was unable to obtain a workable towing solution for several hours. The vehicle ultimately had to be privately towed and has remained
