Cadillac, Chevy, GMC Diesel SUVs May Leak Fuel

NHTSA campaign 25V619000 · Reported 2025-09-18 · General Motors, LLC

critical How serious is it? About this label

Potentially very serious because a leak after a rollover can lead to a fire; the notice does not tell owners to stop driving, but get the tank checked promptly.

What's wrong, in plain English

Some of these SUVs with the 6-cylinder diesel engine had their original fuel tank replaced with the wrong one at some point. The incorrect tank can let fuel leak out if the vehicle rolls over in a crash. Leaking fuel near anything hot or sparking can start a fire. A dealer will check which tank is on your vehicle and install the correct one if the wrong tank is found, at no cost.
