“A couple of days after purchasing the vehicle I noticed very strong odor of gas inside vehicle while in motion and it got noticeably stronger while idling. Took to dealer and they checked it placed me in a loaner. Could not find a problem. This occurred 2 more times over the course of the next week.they repaired what they believed to be the problem but I was back in less than 48 hours later and in another loaner. 4 technicians and 2 service managers later,the bottom half of the engine had to be rebuilt due to a fuel leak due to a faulty o-ring. …”

“I was leaving school and I started to smell gas, so I stopped and checked to see if there was any leaking and there wasn't. A week had went by and I didn't smell the gas anymore but my radio and dash lights had quit working. So I had the fuses changed and the speedometer started working again but not the radio. Several months later my temp gauge started shooting all the way up to hot right after it was cranked. So I had it checked and my vehicle wasn't running hot. The one night I was driving home from town and my car shut off and a temp light was blinking. …”

“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.”

NHTSA complaint #11205581, filed 2019-05, 115,000 miles

“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.”
