Will be driving down the road and horn starts going off, all the electricals flash off and on. Windows, door locks, and rear hatch becomes non operational. Only way to stop is to pull over immediatly and shut car down but not always effective. Alarm will go off all on it's own sporadically.

The passenger side, low beam, headlight has stopped working. The bulb, fuses, and wiring connections have been examined and all appear to be fine. Approximately a month later the stereo electronically locked itself as if it had been placed in another car without a matching VIN. I have been pulled over by the police for a headlight out. Upon entering a search online I see many instances where other owners have reported electrical problems with these vehicles. Some include flashing headlights, failure of door locks, stereos and security lights turning on/off. I see from the various posts that some owners have replaced the bcm as well as wiring harness' that have moisture. There doesn't appear to be a solid fix as I see some posts are recurring. Thankfully I have only received warnings from police about my failed light, however, I don't expect it to remain that way. While a loss of a stereo or electric locks are a convenience loss, the loss of and/or intermittents headlights are a true safety hazard.

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.
