Check engine light appeared. Took vehicle to mechanic and was told the code was in reference to the fuel tank pressure sensor. Mechanic de-activated check engine light. After 2 days, check engine light appeared again. Took to dealer and had code checked. Same issue with fuel pressure sensor. Dealer stated this was a recall issue. Dealer checked with manufacturer and was told this was not a problem. Dealer removed connector at body pass. Check engine light de-activated. After 1 week, check engine light appeared. Traction control and anti-lock brake lights consistency appear and disappear when driving vehicle. This is a daily occurrence. In addition, the automatic door locks will lock and unlock by themselves. Upon starting up the vehicle, all gage lights will flash for a few seconds then go out. A/c stopped working and has not worked since. Steering wheel radio volume button sometimes works and sometimes doesn't. Have already put so much money into repair of this vehicle which was purchased used in 2007 with 57,000 miles. Seriously considering trade-in as this vehicle is a lemon. Have spent half the purchase price in repairs within 1 year of purchase. After searching internet for aztek problems, have found many complaints regarding same issues I have experienced with this vehicle. If these are common issues with this model, why is there no manufacturer bulletin to repair these defects?

I have a 2002 pontiac aztek I cannot drive, we believe the problem is the body control module. 3 mos. In shop, technician called pontiac, dealerships, searched online trying to isolate the problem. I stumbled on www.edmunds.com, was stunned by the #'s of azteks with this problem. The symptoms leading to failure of the bcm-back hatch won't open-key nor button. Eventually it begins working again, but the hatch pops open randomly while the car is in motion, the door locks start turning on and off, the air conditioner blows warm air, the fan won't work. All while the car is in motion. Also, the doors will not lock, the windows will not roll down. The check engine light alternately flashes with a security warning, the odometer quits working. When you turn the car off, all the lights stay on until the battery is drained. None of the dashboard controls work, the only way to turn the lights off and disengage the other electronics is to disconnect the battery. Taking it in for diagnostics produces no results, there is no reading from the computer that will tell a technician what the problem is. Having this failure is a safety issue, a child could open the back doors while the car is in motion, the inability to lock the car is a safety risk to all, the back hatch opening while in motion randomly is also a safety concern. Another issue with the aztek is to open the back hatch with a key requires power to that particular lock, if the lock isn't getting power from the battery, it will not open. I think there are serious safety issues that pontiac should take responsibility for. You can read the number of posts on the edmunds.com website...this is only one site, I am sure there are many others. There is a windshield wiper issue, they will quit working, get tangled during a heavy snow or rain storm.

Service engine light on. Taken to pontiac dealership, told it was the ECM (electronic control module) had gone bad. The ECM wiring harness plugs into a receptacle on the under carriage of the car (on drivers side, in between the front and rear seats), which is exposed to the weather elements and road debris. Corrosion caused the malfunction. No repair available. $934 repair cost to fix/replace entire ECM harness. I went to the aztek owners website and saw several hundred complaints regarding this same item. Some complaints were about the ECM and the bcm (body control module). Ecm supposedly controls all the electronics with the brain/computer of the vehicle. Since a car cannot be inspected with a service engine light on, I was forced to have it repaired$$. Two days later, the awd disable light has come on. The repair agency stated the diagnostic reveals that the awd is fully operational, and no way to reset the awd light! Also, the awd disable light is not an extension of the recently repaired ECM (according to the repair facility), ironically, the ECM deals with all electronics!! Maybe I need a good lawyer? The car performs adequately, but if I want to trade it or sell it some day, I am going to take a "hit" due to the awd light being on. Your website shows no other recalls on this vehicle. I hope this information I type does some good someday. *additional note: vehicle was not repaired at dealership, but was repaired by certified repair shop for $825.

Truck will maintain acceleration, sticking while braking or normal driving. This failure had been checked by dealership which reassured owner problem was fixed. Truck parked in owner's garage not being moved.*ak on three different occasions, the vehicle drives without using acceleration. The brake is used to control the vehicle. After the third repair, consumer is afraid to operate the vehicle. The vehicle also had a fuel gauge fluctuation. The warning bell chimes at different levels before the gasoline is exempt from the tank. The check engine light illuminates. For this matter to be resolved, consumer would like pontiac to buy the vehicle back.
