Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“We are dealing with a problem with the ignition switch/ security system on our car at least once a week now. This issue began about six months back and is definitely worsening. We are experiencing wait times of about ten minutes to clear the security system before we can start the car and have been told this will eventually end up completely failing soon. Now this problem has caused the instrument cluster lights to fail and we cannot judge speed at night without a flashlight. I judge this a safety issue because this is my wife's car and she often has to depend on the car at nights and alone.”

“Bought Impala 2003 the trunk would not open properly, returned to have fixed, said it was working. It was not working properly. During warmer months the back doors would not open, had to open from front door reaching around to back. They noted nothing wrong with them.. My warrenty ran out, two months later passanger side back door handle broke off in my hand. 6 months after the other drivers side back door handle broke off in my hand. This seems to be a big problem, very very cheaply made. The front door handles at times stick and are also hard to open. …”

“Dt: the consumer stated that the trunk latch on 2003 Chevrolet Impala was designed incorrectly. When he put a suit case in the trunk or anything heavy, the latch stuck very high, bent, and eventually the trunk would not shut. The dealer changed the latch once. The foreman and the mechanic at the dealership told him that there was a problem with this model. The warranty was soon to run out. (11/18/05) per invoice, the driveability seemed to idle high.”

“- on december 25, 2006, the contact was driving 35 MPH when her child got out of the child safety seat and opened the passenger door. The contact immediately pulled over and secured her child. The contact stated that this was the first and only time that this has happened. The contact has since called thorobred Chevrolet from whom she purchased the car to find out why the car did not have child proof safety locks. The dealer tried to sell her a new car instead of providing her with information on how she could get some child proof safety locks for this car. …”

“I own a 2003 Impala. Ever since I have owned the vehicle I have had problems with the door locks. The first time I had a problem all four doors locked on their own. The first time this happened my grandson was locked inside on a hot summer day. My dealership in conjunction with GM has tried to fix this several times, without success. In addition to all doors locking {has not occurred recently} sometimes the doors do not lock when the vehicle is put in gear. The driver side door locks sometimes from just closing the door. I do not beleive I can not get more information on this problem. …”
