One problem related to loud engine noise has been reported for the 1999 Chevrolet Suburban. The most recently reported issues are listed below.
I was driving and my vehicle (1999 Chevrolet Suburban 2wd) made a loud noise and vibrated for a few seconds, my check engine light came on and my vehicle would not shift into second gear until I let off the accelerator. I took my car to an automotive shop where the hooked up a machine to see why the check engine light had come on. The machine told them it was my transmission shift silenoid. When I went to leave in my vehicle from the automotive shop it would not go into reverse. I then had to take it to a transmission shop have an expensive complete transmission overhaul on a vehicle with only 97,000 mi. I shopped around at several transmission shops and was told this was very common in chevy/GMC Suburban's and trucks made from 1997-2000. If this is the case, why isn't gm recalling the vehicles for repairs?.
