Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My car will not turn all the way off to be able to remove the keys from the ignition. I understand there is a recall on 2000 models and up. And there is a recall for the same issue on the 1999 lumina - but not on the Monte Carlo, given that the mc is so similar to the lumina, I think there has been a mistake not including the mc. It has happened on several different occasions and is getting worse. I believe the 1999 should be included in the recall also. Please let me know, thank you. If you are not the right people please point me in the right direction.”
NHTSA complaint #10916644, filed 2016-10, 85,000 miles“Brake pads need to be replaced every 3 to 6 months. Rotors were cut and then new rotors replaced. I live in a rural area not bumper-to-bumper, city traffic. I also do not ride my brakes. There seems to be a major defect in the Monte Carlo brake system. I just had to have a new alternator replaced on my 1999 Monte Carlo. I am very unsatisfied and will definitely not buy another GM product.”
