Submission from constituent re GMC executive letter reply in engine stalling/stopping while being driven on the freeway of California. The consumer stated the vehicle stalled several times. Also, the service engine soon light illuminated, due to a faulty ignition coil. The dealer also replaced the ignition switch, as the possible cause of the engine stalling. The consumer continued to experience stalling issues, as the dealer was unable to determine the cause. When the vehicle stalled, the abs and brake warning light illuminated. The dealer found the rear speed sensor connector broken and not sitting properly in the sensor. They repositioned the connector and secured it to the sensor. The consumer discovered a recall, which described the same symptoms he experienced. Recall # 04v289000.

GMC has known that they have intermittent stabilitrak system since oct 1-2008. Don't know if it actually shuts off abs brakes or just sets indicator lights off. Comes on more frequently in cold months. TSB #08-05-25-005 why should consumer pay for either defective steering yoke yaw sensor, reprogramming or new $400 ebcm or $250 dealer service charge each time it comes up. In winter, another article said it was bad connectors. That would be a mfg defect as well. Always comes up in sharp slow speed turns. Already paid for two front hubs as they said it was the speed sensor, problem was not resolved. Braking or known stabiltrak problem over several years should warrant a recall not TSB where the cost is absorbed by the vehicle owner. ,.
