Example complaints

“My car is again in service due to a faulty gas cap. The wire which attaches the gas cap to car keeps getting caught when the cap is be screwed on. Check gas cap light comes on and then the check engine light comes on. This is the 4th time it is in the shop for this reason. I am told I have to check each time I get gas to make sure cap is on properly and that connecting wire is not caught. I don't believe most people have to do this. I believe the gas tank line was installed improperly and therefore it keeps causing this problem. Thank you.”

“Very dangerous fault or defect found on my car. A fuel line that runs along the top of the engine is contacting an opposing metal bracket. This chaffing condition has resulted in damage to the fuel line. The fuel line is protected with padded silver tape; the tape and padding has been entirely cut by the bracket and has created a cut mark on the fuel line. No fuel leaked because of this condition. Had this gone without discovery, the fuel line would have likely burst and allowed fuel to spill on top of the engine. …”
