My aztek started to sputtering one morning, bringing my car to a stop. The car stalled and I would have to restart. It seemed like I couldn't go over 40 MPH. It's just kept hiccuping. I took it to a mechanic and got a new fuel and air filter. Still having problems, I replaced the idle air control valve. That didn't fix the problem. My car continued to get worse and couldn't even get anywhere. Took it to have the catalytic converter replaced, and it ran ok for about two weeks then it began to do it again. Took it back to the shop, and diagnostics read that it needed a new o2 sensor. So I replaced that and it seems like it has only gotten worse. The shop that replaced the converter and o2 sensor spent 6 hours or labor trying to find the root of the problem and they couldn't figure it out; and refused to replace anything else because they were uncomfortable with charging me more money and the car not getting fixed.this morning (about a little over a month this all started) I tried to make it into town where I could take it to another shop, and my car completely gave up. The key wouldn't even turn over. So that has racked me up a nice towing bill. Over 1000 doll as s in the last month, and my car is completely dead. Seems like my problem is the same as everyone else's on the internet with an aztek.

Aztek is 5 yrs old 70,000 miles. Have had problems with stalling after the first few months (was bought brand new!) couldn't find any problem! 9/4/08 was driving late from a game and broke down in the middle of the highway. Had diagnostic done - misfire in cylinder 6. Took it to dealer - costing me $4000 to fix! Needs 2 new heads!!!!

While driving at approximately 60 MPH gauges malfunctioned. The temperature gauge went way up, and the vehicle overheated. Steering wheel locked up, and vehicle stalled. Driver had to wait 20 minutes to an hour before the vehicle would start up again. Owner drove the vehicle back to the dealer, and was informed that the computer wasn't talking to the diagnostic. Dealer told the owner that the defects were taken care of. Yet, these problems still existed. Also, owner was informed that the intake manifold was defective. Vehicle was out of warranty.

Aztek has stalled out without warning while driving. Stalls have taken place during low speeds (usually 10-15 MPH) and always while turning. Has resulted in stalling in the middle of a busy intersection as well as other unsafe situations. When stalls the battery light comes on and steering freezes and must restart car. Starts back up with no problem and no problem lights indicated on dashboard. Service department unable to replicate problem and find no codes set for incidents in vehicles computer. Stalling has now occurred four times, always unpredictably and inconsistently but always on full tank of gas. Vehicle has 30, 000 miles and is in very good condition otherwise.
