“I have been having issues with my azrek shutting off on me in the middle of driving and now it wint even start. I have replaced the fuel pump and vapor sensor due to it not getting any fuel pressure. I have researched and there are 2 different recalls for my vehicle which have not been done due to my VIN not being acnowleged with the recall”

NHTSA complaint #10649959, filed 2014-10, 125,000 miles

“In the middle of turning on a busy road I suddenly lost all power to my car. It seemed as if my car was shut off but the ignition was still in the on position. I almost hit/side swiped 3 different cars. This has been a recurring issue since about feb. 2014. I have gone to different shops and no one can seem to tell me what is wrong. First it was an o2 sensor, then possibly a bad seal on my gas cap, no check engine light comes on. I've gone through fixing everything they say and now everyone seems to be at a loss. I've had this issue both while driving and while slowing down to turn.”

NHTSA complaint #10599033, filed 2014-06, 125,000 miles

“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. …”
