Example complaints

“Automatic transmission will not shift into 3rd or 4th gear, anymore. Roars loudly rather than shifts. When I take my foot off the accelerator at 30+ MPH car acts like cruise control is on - decelerates extremely slow. Rpms stay at 2200+ at 35 MPH. Also now a little higher on temperature gauge.”

“I have had an 99' Oldsmobile Alero for 7 years. It has had almost every problem listed on this website. It has had an over heating problem every year since I got it and I have spent thousands in repairs for the cooling system, fuel pump, poor interior manufacturer, AC/heater blower motor settings failure, fuel gauge failure, transmission leakage, poor springs/struts, gear slipping, hard starting, water leaking in from rain under glove compartment, off alignment (set three times in year), poor gas mileage, overheating or running above normal temperature and sudden overheating without notice…”

“1999 olds Alero gls, bought the car in may,2004 with 23,000 miles on it. From day 1 I have had nothing but problems with it mostly brakes, car has extended warranty on it. The rotors grind, pulsate, squeak, the calipers make cracking noises sometimes brake pedal goes to floor. The dealership refuses to fix the problem or says it will not do it for the mechanic, when I drop it off I allowed the service manager to hear it he also verified the sound, only to get the car back being told it won't do it. The rotors have been replaced 4x the brakes 3x the calipers 2x, I still have the problem. …”

“1999 Oldsmobile Alero (out of warranty) began to have problems with transmission slipping occasionally during the summer. I was told no problem could be found. While driving home last evening, the service engine soon light came on as well as the trac off light and it was very hard to get the car to go more than 30 MPH on a 50 MPH highway very nearly causing an accident. By the grace of god, that did not happen, but now I am told that the transmission may possibly be bad or it could be several other things. In either case, it would seem to me that someone should have found the error before. …”
