Description of the problem | Was returning from a 300-mile trip on june 17th when i received a "service 4wd" message on the display console. Called gm dealer service shop and set up appt for june 28th (earliest available date). Three days later, pick-up auto-shifted and locked into 4wd. Next morning, june 21st, drove pick-up to dealer service shop. Technician was able to take pick-up out of 4wd, but said he could not guarantee it wouldn't slip back into 4wd. I continued to receive "service 4wd" messages. On june 27th, while making a left-hand turn across oncoming traffic, pick-up again auto-shifted and locked into 4wd. The wheels locked while in the turn, stalling the vehicle with oncoming traffic barreling down on me. I did not think i would survive. Fortunately, opposing traffic was able to swerve around me, and i was eventually able to limp the pick-up through the left-hand turn and out of direct traffic. Vehicle went into dealer service shop the following morning (june 28th), still locked in 4wd. Service shop had the pick-up for 18 days. Final verdict: pin tension issues and fluctuating voltages in connector, which miss-signaled the vehicle to auto-shift into 4wd. This is the third time i've had issues with the 4wd on this pick-up. The first time i received the "service 4wd" message at 214 miles. Vehicle auto-shifted and got stuck in 4wd. Dealer service shop repaired issue. At 5,096 miles, the pick-up again issued a "service 4wd" message and auto-shifted into 4wd. Was diagnosed as an internal short; and the 4wd selector switch replaced. This third time was determined to be another internal short. I filed a report with gm. They determined the pick-up was still safe to drive even though the vehicle had auto-shifted into 4wd on 3 separate occasions and even though the 3rd time almost got me killed. |
