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?

At 51,000 miles engine overheating when stopped at traffic lights. Added antifreeze, but did not fix the problem. At same time ac failed. Then electrical system started failing. Alarm going off for no reason, doors locking and unlocking themselves, rear hatch opening, and all gauges lighting up then going blank for 5 - 10 seconds. Took to dealer who stated that I had a failure in the intake manifold gasket, a leaking fuel filter, a shot ac system, and needed to replace the body control module. Dealer also stated that they have had to do the same work on many Azteks. Took to my regular mechanic for verification and repair ($600 less than dealer wanted). Paid $1156 for intake manifold, fuel filter, and ac check. Mechanic doesn't believe that there is anything wrong with the ac system, but the problem is related to the body control module. Can not fix the module at this time - have been given estimate of $800. Seems to me that this module is a safety issue and that NHTSA should issue a recall and have GM reimburse those that have already had the problem fixed. This issue has been brought up by many Aztek owners both on this site and others. It is really alarming to be driving at highway speeds when suddenly all the gauges go blank, even if just for a few seconds, not to mention doors locking and unlocking themselves and the alarm going off for no reason. By reading other complaints I should look forward to replacing wheel bearings also. Please look into this and do something about it.
