★ Top Answer
The 2011 Buick LaCrosse is equipped with dual catalytic converters for added reliability. A catalytic converter in the exhaust system helps reduce emissions by processing harmful gases. While converters typically last over 10 years, they may become contaminated, clogged, overheated, or damaged over time. These issues can lead to poor engine performance, trigger a check engine light, and even result in engine shutdown. Overheating of catalytic converters can be caused by factors such as misfiring spark plugs, leaky exhaust valves, or a malfunctioning oxygen sensor. Often positioned beneath the vehicle, catalytic converters, like other exhaust system components, are vulnerable to damage from road debris or hitting a curb.
