2003 Pontiac Aztek Owner Comments

problem #10

  • miles


Dash losing different component operation. Started with fuel gauge and temperature gauge then affected radio lights and lcd display. Now vehicle speedometer has become erratic and untrustworthy. Radio lights and display an inconvenience but the combination of fuel and now the speedometer not reading properly is causing a concern for safety. At the rate this is going the whole dash will be malfunctioning soon. According to what I see the parts alone can be $300 - $500 plus the repair charges. Internet has countless entries about the electrical problems on the Pontiac Azteks but no service bulletins on the NHTSA web site and no mentioning of any recalls by Pontiac. Why isn't the NHTSA looking into this with so many problems being shared on the internet" why are the owners being required to pay for these repairs since it's such a widespread Aztek issue"

Leakage from the fuel tank inlet filler pipe (inlet check valve). Similar issue as to NHTSA recall campaign number 07V349000. However, 07V349000 only included vehicles for the Pontiac Aztek built in May 2003 for the recall phase. I purchased my Aztek in Feb 2003.

Our gas tank inlet check valve is leaking on our 2003 Aztek. There was a recall on this exact part in 2007. We were not the owners at that time and they owners did not take care of it. It is now leaking and GM is refusing to let us use this recall. They are saying it may be covered under a special coverages policy but that we have to pay to take it in. They will not haul it in, but we will have to drive it which is very unsafe for a leak that excessive.

2003 Pontiac Aztek - fuel smell for several weeks with no obvious cause. Weather warmed during this period and smell became stronger with increased ambient temps. About three or four weeks later, fuel was found on the ground beneath the filler vent tube beginning with a small damp spot and eventually becoming a puddle (only when tank was filled). Took it local dealer where they informed me that there were no recalls for the 2003 model year and it would cost me $1200 to replace the tank. I was informed that they would accept no responsibility for the vehicle or accidents if I chose to drive the vehicle in this condition. I went home, researched the recalls and discovered that there was a recall for the 2004 model year. My vehicle was manufactured in may of 2003 and the recall began in October of 2003 for the 2004 model year. I returned to the dealer, told them that they had 12 hours to make up their minds on how they wanted to handle it. My family had to go to duluth that weekend and we had no other transportation. I told them that if anything happened as a result of that trip, they could claim all they wanted that they were not responsible but a jury would certainly see it much differently. They called me the next morning and scheduled an appointment to replace the tank and I agreed to pony up $100 of the cost just to be fair. The vehicle had about 60,000 on it at the time.

I just bought a used 2003 Pontiac Aztek yesterday from a used car dealer, and today the fuel system is leaking gas. The dealer said that the car had not been wrecked. I have not ordered a carfax to verify him. There are a couple of recalls for this problem already but a Pontiac mechanic said over the phone that my vehicle is not affected. It seems like my vehicle should be added to the recall list because of so many similarities. There are approximately 21,000 units affected by the current recalls. It just does not seem accurate that all of those fuel systems were considered faulty and that my Aztek's fuel system is considered fine when it is leaking gas. My Aztek was manufactured in November 2002. The service engine soon light is on and stays on most of the time. The dealer swore the problem was just a loose gas cap and there was nothing else wrong with it. When I bought the car, the tank was filled just above empty and I filled the tank that evening with 15.8 gallons of 87 octane gas and woke up today with the entire inside of my home smelling like gasoline. My husband was able to see that the gas is leaking from around the joint between the filler hose and the fuel tank. The leak is not heavy or flowing it is just steadily seeping. The vehicle still drives really smooth. But I am not sure how explosive a gas leak is and I am not driving it until I do. I have a scan gauge and it estimates the car getting around 7mpg. The vehicle has 92,500 miles on it and only one previous owner. All of the complaints that I have researched online seem identical. I just want to know if this fuel leak is from a common faulty part that the manufacturer is responsible for.

The contact owns a 2003 Pontiac Aztek. The contact smelled a strong odor of fuel outside the vehicle. He also observed a small amount of fuel spilling from the lower portion of the fuel tank. The failure occurred without warning. The vehicle has not been taken to an authorized dealer for repair. The VIN was excluded from NHTSA campaign id number RQ06009 (fuel system, gasoline:storage:tank assembly:filler pipe and cap), although the failures were identical. The failure and current mileages were 74,000.

1)when I removed gas cap to fill tank with gas, I heard a hissing sound coming out of the gas tank. When trying to fill tank with gas, hose kept clicking off and would not allow me to put gas in the tank. I went to a different gas station and the same thing happened. I have since been unable to use the car as I can not fill the tank. 2)this second problem has been ongoing since I purchased this car. The "service engine soon" light keeps coming on a regular basis. I have had this checked out each time and the mechanics always have a hard time identifying the problem. This has been extremely costly. Further more, the vehicle can't pass inspection with that light on. 3) this third problem has also been ongoing. I have to replace my brakes at least twice a year. They wear down quickly and make an awful grinding noise. The mechanics cannot understand the reason for this either. Except to tell me this car is defective. 4)in the last year or so, when I make a turn in either direction, there is a grinding noise. My transmission fluid levels are always good when this happens. 5) the hatch does not open when the automatic opening button is used, must always have someone in the back to open it as I simultaneously push the button. 6)when I press the brakes to stop, it feels like the brakes disengage or the anti-lock brakes kick in and this happens when road is dry this car has been a piece of junk since the day I bought it and has caused multiple financial and emotional problems with all it's defects. I will never buy a Pontiac or GM car again!!!!!!!!!!!

(1) 2003 Pontiac Aztek, 41500 miles in service 2 years 3 months, with no identifiable cause started to leak gas at the filler neck. (2) gas leaked very quickly when tank was filled. (3) due to warranty being only 36000 mi dealer examined leak for $100 diagnostic charge, but not part of tsb and normal bumper to bumper warranty expired due to mileage, dealer wanted $900 to fix it. After appealing to Pontiac corporate, goodwill extension of warranty got tank replaced. Dealer kept part. I personally think if no cause of leak is found (as in collision type damage/vandalism) gas tank should be covered as part of emission control system (5 years/100,000 miles I think...). what good is an evaporative vapor collection system if you are leaking gas all over highway?
