Chevrolet Tahoe

I have 19,000 miles. After each oil change, the engine begins to idol rough, the vehicle violently shakes and the traction control and ABS turn off. The first time this happened it was determined that there was a cylinder (4) failure causing a missfire. This was corrected under warranty.

This is very similar to what is…

This vehicle is subject to Safety Recall N252494000 / NHTSA Campaign 25V274 for a known L87 6.2L V8 engine defect.

On XXX and again on 02/14/2025, the vehicle suffered total loss of propulsion on [XXX], once causing a missed professional licensing exam and requiring emergency roadside repair. The vehicle's…

Engine failure of the 6.2L L87.
