Buick LaCrosse engine shuts off during hard right turns, ongoing issue on Buick LaCrosse

Some Buick LaCrosse owners report experiencing engine stalling issues, particularly when making hard right turns, which may be linked to problems with the fuel system and ignition. Symptoms can include dashboard alerts such as "reduced engine power" and "starting disabled" when the engine unexpectedly shuts off. These incidents raise significant safety concerns, as losing power steering and brake functionality can create dangerous situations, especially in busy traffic. In certain instances, owners may find that turning the key off does not immediately stop the engine, necessitating multiple attempts to shut it down. Repair costs for addressing these engine stalling issues can vary, with estimates around $310 for the 2008 model at 53,000 miles. It is recommended that affected owners have their vehicles inspected by a qualified mechanic to diagnose and resolve these issues promptly for their safety.
