Two problems related to brake disc rotor have been reported for the 2002 GMC Sonoma. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2002 GMC Sonoma based on all problems reported for the 2002 Sonoma.
On my 2002 GMC Sonoma truck the front driver side brake pad was worn off and the rotor severely scored and ruined by 14,000 miles, to the extent that the GMC dealer declared it unsafe to drive. Mean while the passenger side front brake pad was largely intact and the rotor perfect. Also the abs system failed to stop truck promptly or smoothly on several occasions.
The front/rear brake rotors wear out prematurely, causing extended stopping distance. Dealership repaired the problem.
