Selected complaints filed with NHTSA by 2003 Chevrolet Cavalier owners, lightly cleaned up (personal details are redacted by NHTSA).
I own a 2003 Chevrolet Cavalier ls and on dec. 25 when I turned on the rear defrost button smoke started to come out from inside the steering wheel column. I could not get the rear defrost to turn off so I had to turn off the car and remove the fuse to it. Shortly after this incident the power windows have stopped working and the fuse to them is still good, I replaced it just in case but the windows still do not work. The odometer has also stopped working so I have had to guess my speed. I feel that this is a huge safety concern since the rear defrost does not work I cannot see out the rear window on cold days, I also cannot tell how fast I am driving which can cause an accident, and the power windows have stopped working. The car is due for inspection next month and I cannot afford to fix these problems, this is my only vehicle and rely on it to get to and from work everyday. …
Tl* the contact owns a 2003 Chevrolet Cavalier. The contact was driving 30 MPH when the defroster was engaged and the contact began to see black smoke coming the vents.

A police report was filed. The vehicle was destroyed. The failure and current mileage was 90,000. The VIN was unavailable. Updated 9/27/11 updated 3/29/12
The tires shake and vibrate around sixty miles/hr. So I took them to sam's club to their tire center in December of 2003. They rotated and balanced the tires. I drove the car for one month, then the tires started doing the same thing over again. About one month later, I went back to sam's club and they balanced my tires again. So here it is March of 2004, the tires are doing the same thing again shaking and vibrating around sixty miles/hr. I called Goodyear , they told me to bring the car in. They looked at the tires, and said that the rear tires were worn on the inside, and that I would have to take the car back to the dealership to get the tires fixed. They could not diagnose the specific origin of the vibration. Basically, for a brand new car, we should not have these kind of problems at 24,000 miles (as stated by mechanics from Goodyear, sam's club and Firestone). 5. …
Problem started same week I purchase vehicle brand new. GMC would not exchange vehicle, they just kept repairing it as it broke down. I feel very unsafe in this vehicle, they did not care. Clutch was rubbing against main line, failed twice. Rear lights burned out 3 times, springs on seats popped out 3 times, gas pump went out once, heater/ac went out twice, locks would not open, 3 times, pain chipped off bumper, once. Rear seat clips snapped, once. Headlights, water leaked in. Twice I had a head on collision in June/2007...air bag did not deploy.
The front defroster/defogger would not blow air. The ventilation control cable was replaced because there was a "kink" in the cable that caused the air to not be directed to the defroster. The service tech recommended that I not use the recirculate function on my ventilation system as it seems that when the control is in that position, the cable will start to "kink." this is unacceptable as I should be able to use every function on the ventilation system.
While turning on the turn signals the turn they failed to come on. Consumer took vehicle to the dealer for inspection, and the mechanic replaced the bulb and socket. The consumer informed the mechanic that this problem occurred more than once and had not been resolved. The right and left rear turn signal failed, there was shaking in the dash when the blower was on due to the A/C accumulator.
Defroster control broke due to freezing weather (about 30f). Defroster no longer functions so it is difficult to clear windshield in cold or damp weather. Dealer attempted to repair, but could not for original estimate of $477. Wanted to charge another $630 to fix the problem (for a total cost of almost $1100). I feel the cost is outrageous to repair a necessary safety item.
While driving at any speed heater did not work. Vehicle was taken to the dealer, and heater was replaced. Also, on two different occasions dealer replaced wiring harness and connection wires. On another occasion entire brake light assembly was replaced along with the sockets. In all, vehicle had been to the dealer six times in seven months.
I want to make it clear I have taken over payments of this car and will have title when it is paid off. The car had been running great except for the A/C no longer works, and I was driving getting up to 40 MPH and the car just died, I couldn't get it to restart it ended up being the fuel pump went out, it was quite expensive to fix.
I bought the car brand new arround 04/2003 Chevrolet Cavalier 2003 since then I reported several times back to the dealer ship with the following problems:drivetrain - clunk noise during low speed turns A/C - difficult mode/temperature setting operation . Steering - momentary loss of power assist. Steering - rattle/knock when turning wheels - front/rear wheel squeaking noise ---all those complaints are never been taken care off - they allways had some "low excuses for me - like the wheater/rain/dirt on the wheels (I live in the city ...not on a dirt road..) anyway the only complaint they taken serious is that I brought in the car now for the 3rd time to repair the right signal light - last time just today! I reported again all the other problems, with the sucess that they at least orderd now a "new part" for the A/C, everything else is again been "played" down. …
