Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While driving at approximately 35 MPH both bottom rear cradle mounts failed due to corrision, causing motor to fall and disconnect steering mechanism, resulting in a crash. Consumer contacted gmc, and gmc insisted that consumer's vehicle did not fall under recall 00v189000 because it was manufactured after specified date. Front mounts also showed indication of failure.”
NHTSA complaint #893251, filed 2001-08“After placing vehicle in the park position while vehicle was turned off for about 15 minutes, consumer smelled smoke coming from outside.

NHTSA complaint #892438, filed 2001-07“While driving during day time vehicle was fine. But, at night noticed vehicle would idle high & start to overheat. Vehicle would stutter like it was stalling.

NHTSA complaint #875432, filed 2000-11“Engine head had been replaced once, and had cracked once again. Dealer has been contacted.
