The failure pattern owners describe
Owners of the 2007 GMC Sierra report three main body problems. Dashboard cracking is the most common complaint: cracks appear on the passenger side above the airbag or on the driver side, sometimes as early as 20,000 miles on garage-kept vehicles. Plastic pieces break off and fall into the instrument panel, and owners cite sharp edges as a safety hazard in a collision. Replacement costs run around $1,000. GM has issued no recall and offered no solution.
Frame and undercarriage rust develops prematurely, even on garage-kept trucks, particularly those driven in the Northeast with road salt exposure. One owner reported extensive rust on a truck at 20,000 miles, with rust present on frame edges, holes, mounts, and brake lines—worse than a 1991 model they traded in. Dealers blame winter conditions but have taken no corrective action.
Driver door locks have failed on some trucks, leaving owners unable to unlock from inside. One repair quote exceeded $1,200. Owners report this is a known issue in the Sierra TK community. None of these issues carry an active recall.
