2012 Buick Lacrosse engine problems

“2012 Buick LaCrosse V6 (Fairfax Plant). The vehicle suffered a sudden, complete loss of engine power and forward propulsion while traveling at highway speed, cutting off mid-drive with no warning. This occurred alongside a persistent StabiliTrak malfunction; the dash showed repeated "Service StabiliTrak" warnings before the failure, then turned bright orange with multiple warning lights and a message instructing me to activate my turn signal and pull over before RPMs dropped to zero. Because power cut out instantly, my [XXX] son (passenger) and I were trapped in the center lane of a dense, multi-lane highway. I was forced to dodge high-speed traffic and coast the dead vehicle across multiple active lanes to reach the shoulder, creating an imminent collision risk to us and other drivers. We were then stranded on the narrow shoulder awaiting a tow, with traffic passing within feet at highway speed. Both my son and I have CMT2A (Charcot-Marie-Tooth disease), a neuromuscular disability limiting mobility; we were incapable of quickly evacuating the vehicle or reaching safety up the embankment, leaving us trapped in a highly dangerous position. No official inspection…”

“All the specific details are unknown, but I had a mechanic work on my car and the problem that he had to fix. He stated that it should’ve been detected, but it was something wrong with my car, letting me know that I had the problem and also I have to keep replacing my camshaft timing Solenoid my car keeps giving me error codes P0011 and P0128”

The contact had the vehicle towed to a local dealer, where it was diagnosed and determined that the engine had seized and needed to be replaced. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 170,000.”

“The charging system in my vehicle is no longer working. There's been a recall done for the charging system. It was fixed back in 2013 before long before I bought the vehicle. It's only been nine years since it's been fixed and now it's not working again. I'd like this matter to be looked into as I believe it's faulty at no fault of my own.”
