“I was driving down the road, got a quick message. It said something about lean and to pull over (on dashboard). And by the next stop light the engine stopped. The truck no longer turned on. It did put my life in danger because it left me stranded in between two lanes. The truck was inspected by one of my mechanic friends who owns a shop. He let me know my engine is seized.”

“Complete engine failure. Absolutely insane. All lights on dash, engine seized while driving!!!!!!!!!!!!!! Unbelievable that GMC keeps making us fix issues and pay for it! They won't cover the cost. This has been happening too much and putting my family at risk!”

Should you keep driving it?

This page can't tell you that. 0 of 37 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
