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. *TR

I HAVE HAD THREE MAJOR PROBLEMS WITH MY AZTEK. WHEN THE VEHICLE WAS ONLY A FEW MONTHS OLD, THE COMPUTER SYSTEM WENT OUT AND HAD TO BE REPLACED. THIS, OF COURSE, WAS COVERED BY THE WARRANTY, BUT WAS A HARBINGER OF THINGS TO COME. BOTH THE CONDENSER AND THE COMPRESSOR HAD TO BE REPLACED, NEITHER OF WHICH WAS COVERED BY THE WARRANTY; I WAS WITHIN THE ALLOTTED TIME, BUT HAD A FEW HUNDRED MORE MILES ON THE VEHICLE THAN WHAT WAS ALLOWABLE. VERY EXPENSIVE. SHORTLY AFTER THAT, I BEGAN TO HAVE TROUBLE WITH TRANSIENT OVERHEATING. THINKING THAT THE THERMOSTAT MIGHT BE STICKING, I TOOK IT TO THE DEALER, WHO AT FIRST SAID NOTHING WAS WRONG WITH THE CAR. WHEN I WENT TO PICK IT UP, THEY TOLD ME THAT THEY HAD DISCOVERED THAT THE INTAKE MANIFOLD GASKET WAS LEAKING AND THAT THE CAR WAS NOW INOPERABLE. THE REMEDY DUE TO LABOR WAS CLOSE TO $1000. I WAS QUITE UPSET, AND TOLD THE DEALER THAT, SINCE THEY HAD SOLD ME THIS CAR, WHICH HAS HAD NUMEROUS PROBLEMS, THAT I THOUGHT THEY SHOULD EITHER FIX IT OR PROVIDE ME A FAIR TRADE. THEY TOLD ME THAT THE CAR, WHICH I PAID $26K FOR, IS NOW ONLY WORTH ABOUT $6K BECAUSE OF ITS POOR RESALE VALUE. I REALLY FEEL LIKE A VICTIM AND THAT THE LEMON LAWS SHOULD BE REVISED TO INCLUDE VEHICLES THAT HAVE MULTIPLE SYSTEM FAILURES. *NM

THE LOCAL DEALER ALSO UNDERVALUED MY CAR'S TRADE-IN VALUE WITHOUT KNOWING THERE WAS A LEAK. IT WAS NOT VISIBLE.
