Example complaints

“Consumer complained about a fuel injection system problem. There was 50,000 miles on the vehicle, and it was no longer under warranty. The defect was the result of poor gas that was used in arizona. Consumer had the fuel injectors cleaned and flushed. Several weeks later the problem recurred.”
NHTSA complaint #10101235, filed 2004-11, 50,000 miles“My car has had a continuous problem with my fuel injections, specifically injections 3 and 4. Number 3 has been replaced twice and 4 once. This started 11/14/2001 with the most current happening on 11/12/2003 after supposedly being repaired on 11/5/2003 and 10/17/2003. I have spoke to GM on separate occasions with the same response. Because my car now has 98,200 miles on they can't help me. The first time that the injections started to give me a problem it was covered under an extended warranty and at that time I only had 64,047 miles on my vehicle. …”
NHTSA complaint #10046875, filed 2003-11“Since I have had the car I have had repeatedly had a problem with the fuel injectors. In the beginning while under warranty the injectors were replaced after the third time I was told that they just clean injectors now and it's caused by bad gasoline. In all my other cars I have not had any problem using standard oil gas. Even the dealer buys the same gas at the same station for all there cars. Lately when I had the injector problem again they quoted me $140 to fix the problem when I said I had it done the other times for less they automatically reduced the price to $64. …”
NHTSA complaint #10069962, filed 2004-01“Consumer is having problems with fuel injection system:injectors. One year ago she had them replaced by the local mechanic, then twice they were cleaned by the dealer. Afterwards, she had to have 3 of them replaced. All of this because the engine light came on, stating that engine needed to be serviced soon. All of this started when vehicle started to jerk, and she had it checked. Consumer would like to have help with all of this servicing.”
NHTSA complaint #10033977, filed 2003-08“Hose disconnected from the gas filter caused gasoline to leak from the vehicle. The consumer managed to reconnect the hose to the filter which temporarily remedied the problem. At a repair shop, a new filter was installed when the mechanic installed the fuel filter. Consumer noticed the connection from the rubber hose to the filter was only a plastic snap and not a solid connection like the other end of the filter that goes to the engine. Consumer felt the plastic snap could snap again and cause serious or deadly injuries.”
