Vehicle lost engine power on the road. Light display came on stating engine reduce power. It would not pull the trailer. Had to pull over and the display went away only to appear again later. We brought vehicle to chevrolet dealer . The part needed to hopefully fix is on backorder. There is also recall with no available remedy. This is a revenue generating vehicle. We had this problem happen on and off. Dealer didn't want us to bring in until the light physically stayed on dashboard for them to assess vehicle. It was now been in shop for over 2 months

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
