What owners wrote

“My vehicle is under the L87 Recall from GM for engine failure. In September 2025 it was given the recall “fix”, different thicker oil. But on July 1 2026, my engine seized while I was driving 60 mph on the highway. GM has since replaced the entire engine and the radiator. But the “fix” obviously did not work.”

Should you keep driving it?

This page can't tell you that. 0 of 30 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.
