2008 GMC Yukon Denali Problems

The upper dash may crack, most commonly on vehicles in warm climates and exposed to a lot of sunlight. The common repair is to replace the upper instrument trim panel. Information on a technical service bulletin or extended warranty is not available at this time.

The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault. The warranty has been extended on some of these units to 7 years or 70,000 miles.

A Loose or worn gas cap may cause Check Engine Light to illuminate.
