A couple of days after purchasing the vehicle I noticed very strong odor of gas inside vehicle while in motion and it got noticeably stronger while idling. Took to dealer and they checked it placed me in a loaner. Could not find a problem. This occurred 2 more times over the course of the next week.they repaired what they believed to be the problem but I was back in less than 48 hours later and in another loaner. 4 technicians and 2 service managers later, the bottom half of the engine had to be rebuilt due to a fuel leak due to a faulty O-ring. Car VIN was not included in recall and cost over 1200 to repair.

I purchased this car used. When I first purchased it, I smelled an strong odor of gas/fuel. When I researched the car on the internet, the search revealed there was a recall on the fuel system of the 2005 Pontiac Aztek. After reading more in detail about the recall, the search found that the fuel pressure regulator were produced without an O'ring and retainer, which caused the fuel to leak. I took my car to the dealership to be checked. They found that fuel was leaking and the fuel pressure regulator had to be replaced and the throttle body was choking. I contacted GM and I was told that because my VIN number did not read from an area that had recalls, I would not be helped in this situation. I responded that my car had the same issues as other cars. They also stated that they could not find any recalls on the 2005 Pontiac Aztek, but I have found complaints on the NHTSA web site, as well as on the internet regarding this issue.
