I can smell a gas leak coming from my aztec. I do know there was a recall on the fuel system and it was never honored because there was none at that time. There is now a leak as well as a major smell of fuel coming from it. I did call about the recall and they don't want to honor it even thou it was never replaced the first time. It is going to cost me about $1500 to have it replace....I do believe the recall should be honor. I call the dealership where it was bought brand new. And spoke with the owners. And they said they never received the letter to have it replaced. The dealership said it out of warranty and they will not cover it even thou the recall was never done on it.

Not exactly sure of the date of these incidents, but I can smell fumes coming through the vents when I am driving, had to get this checked a few weeks ago. The mechanic said the gas was leaking replaced this part. I am still smelling something in the engine area. I am not sure what and why. The vehicle also feels like it is shaking when I apply the brakes, and the brakes are fine. It usually does it when I am braking and also when I go past 40mph. It has gotten really bad that I am thinking about getting rid of vehicle and not having a vehicle. Also, I can hear a cranking noise in the steering column when I am turning that makes me think the vehicle is breaking in half. I have had to replace the gas cap last year as well for fumes.

The contact owns a 2003 Pontiac Aztek. The contact stated that the brakes did not always respond and needed to be applied repeatedly in order to function as normal. The contact also stated that the anti lock brake warning light illuminated. The vehicle was taken to a repair shop, where faulty sensors where replaced; however the warning light remained illuminated. The vehicle was then taken to a dealer, who found a leak on the fuel injection system. The contact replaced the fuel injection system. The vehicle then experienced difficulty driving uphill. The vehicle's speed decreased and the contact was unable to accelerate. The mechanic stated that the pivotal joints in the rear wheels were defective and caused unusual tread wear and tear of the tires. The vehicle was included in the recalls associated with NHTSA campaign id numbers 07E021000 (fuel system, other:storage:tank assembly:pressure relief devices) and 07V349000 (fuel system, gasoline:storage). The manufacturer was made aware, however no assistance was provided due to mileage on vehicle. The failure mileage was 150,000. The current mileage was 160,000.
