catastrophic engine failure catastrophic engine failure catastrophic engine failure

While driving on the freeway, the truck suddenly displayed a flashing check engine light along with multiple warning/error messages. I was able to limp the vehicle to the nearest mechanic, where they inspected it and confirmed catastrophic internal engine failure ($13,XXX). Upon removing the oil pan, they found large copper-colored metal chunks and metallic glitter throughout the engine oil, indicating severe internal bearing/component failure. The vehicle is no longer safe to operate and now requires major engine repair or replacement.
