What 2005 Pontiac Aztek owners say
Most recent owner complaints, unedited.
The vehicle will cut completely off while coming to a stop. While in motion and applying the brakes to come to any kind of stop, it turns completely off. It happens on a daily basis since I purchased it in 2015. Whether coming off of the highway, or just coming to a stop sign on a city street, the vehicle cuts completely off.
Ignition keep getting stuck in accessory mode or the key get stuck in ignition
All-wheel-drive disabled and anti-lock brake lights came on, in my car I have no power can really make it up a hill doesn't want to go anywhere, it just started happening don't know what's wrong with it. And this happened while I was driving home from work
Tl* the contact owns a 2005 pontiac aztek. The contact discovered that the entire fuel system was corroded and leaked fuel. The vehicle was taken to an independent mechanic, who diagnosed that the fuel filler neck fractured. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 98,000.
My main temp gauages is acting haywire. The radiator temperature gauge is supposed to be in the (based on a wall clock) 0 (12) to 6 hand position with 0 being hot and 6 cold. Gas gauge is from the 6 to 12. The temperature gauge has flipped over to the 10 or 11 position such that when the gas tank is full, that needle can't even go all the way to the 12 position because it is blocked by the temperature guage. I have no idea if my car is overheating or if the temp gauge is affecting the gasoline level gauge.
I actually got on the site to research recalls on another vehicle we recently purchased and out of curiosity included the aztec we still own. No recalls showed? I couldn't believe it since it has been nothing but trouble from day 1. Just as all others described the ignition messes up all the time. My gauges go crazy! Will show no gas and it will be full or it will go way over full into other gauges. Speed goes crazy I could be doing 25 and it will say 80. The belt...,,,, I have litter ally replaced it every 4 months after owning the car a year and everyone says "you sure it is'nt recalled ?" so glad I do not have to drive it anymore but if someone else does they will be in just as much danger as we were! Now we own a jeep that has a recall that was recalled in 2014 but they don't have the parts to fix it with!!! Oh and yes it's the ignition.
The vehicle has seemed to stall twice. Upon further discussion with the driver, the steering also locked. This seemed similar of the same as the gm recall for faulty ignition switches and key slots. Pontiac was contacted but the response was that the vehicle was not under a recall, was out of warranty, and that repairs would be the expense of the owner. Pontiac did not seem concerned about a potential extension of the gm recall list. Wouldn't you think that gm would be very interested in understanding if the pontiac aztek is affected. We are now very concerned about driving the pontiac aztek.
When the radio is turned on an extremely loud screeching sound is heard. The noise continues even after the key is turned off. There is an electrical crackling sound in the dash and when the brake is depressed there is a loud crackling sound. No gauges work correctly. They either peg out or operate out of the expected range of operation. The airbag light flashes off and on. The awd light is on all the time. The gas gauge always below "e".
Both the antilock brake warning light & the awd lights are on & no one can determine why.
