Example complaints
One per model year, chosen for length and detail. Personal details are removed. They are consumer reports, not findings.
2004: “Low beams on lighting goes out for no apparent reason. This has happened two times in the last two weeks. Dealership says they just can't find anything wrong. Although they had another vehicle there with same problem. This seems to be a recurring problem with GM SUV's. My 1994 gmc did the same thing and I heard reports of other gmc's doing the same thing. Not good on interstates at night.”
