Acceleration & cruise controlEngine & cooling

Engine rpm surges to over 3000 without warning. This often happens when the car is initially placed in drive after starting the engine. The driver may need to suddenly apply the brake if behind a car. The high rpm also acts as an undesired "cruise control" system, though the vehicle is not equipped with "cruise". The driver must also firmly hold the brake pedal down while stopped as the car will lurch forward. *Tr

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. *Tr

I was driving about 4 mins. I stopped at light and car cut off. Car never cut on after. I just purchased car on june 26 2013. I was told there aren't ant problems with the car and if I have any problems to bring it back I brought it back to find that they didn't value their word. They wouldn't accept car back and exchange for my purchase. Although I am unable to drive car til this day. *Tr

It started running on its own and the rpm's went up to 3000 in park gear. I took it back to colonial service department. They looked at it and decided that I needed to have my iac - idle air control motor replaced. The next day 4/28/11, I picked up my car and drove it home. It seemed as though everything was fixed and working fine. Until, I drove my car on 4/30/11. That is when my car's rpm went up to 3500 in park gear. I was able to drive my car from south boston, ma all the way to the car dealership in watertown,...

ma without stepping on the gas pedal at a speed of 40 mph. Now the dealership is saying I need to replace the tps - throttle position sensor. I am not sure this is going to fix my problem but I know that I needed to report this to nhtsa. Most likely you will be received another email from me shortly. This is something that needs to be address and resolved. I do not want to be in my car and have an accident because of this problem. I don't want it to seem like this problem was never reported to pontiac or nhtsa. This can save a lot of peoples lives. Please have someone research this problem and get back to me. Previous email sent to [email protected] on 4/24/11- dear sir or madam, I am presently having a problem with my 2003 pontiac aztek. Within the last four days, while driving my car it started coasting/driving on its own with me not having to press the gas pedal. Like on 4/24/11, I was driving at a speed of 40 mph on the road. I took my foot off the gas pedal and the car continued to drive by its self at that speed and I was not using the cruise control. Matter of fact I never use the cruise control. When I stopped the car and it in park the rpm needle went between 2000 -3000 rpms. Surge or reving my engine very loud. I believe this is very dangers and would like for you to tell me what needs to be done to fix this problem. I took it to the colonial gmc car dealership in watertown, ma on 4/18/11 and 4/23/11 because this problem is not showing up.

2003 Pontiac aztek. Took in due to fluid leaking into oil and causing it to look like a "milky" substance. Told that these vehicles are known for this issue and that the problem was with the intake manifold gasket. Had that replaced (over $1,000) - then discovered still a leak - now they are saying it probably needs an engine. The vehicle is not even 10yrs old. I read another description similar to this. How many individuals have to be gouged before something can be done about this. If this is a known problem with these vehicles, seems like something needs to be done to stop the manufacturer from preying on their customers. *Tr

The engine started to run hot and after investigating the problem at home we discovered that the engine cooling fans were not working. We did not find any leaks or disconnected belts or hoses. We have not had a professional look at it yet but we are very certain that the fans are not coming on. *Tr

I bought my grand prix from chip banks in duquoin, il. In august of 2006 and it had only 39,500 after owning it for 4 months the head started to misfire. I had someone look at it and they said it had been healy coiled to just temporarily fix the problem. I contacted the dealer I bought the car from and they said they would fix my car but I had to pay for it. I did not buy the extended warranty for my car because I could not afford it and it did not have very many miles on it so I thought it would be okay. I had it...

healy coiled to repair it and it held for 8 months and now all the other rocker arms are needing healy coiled in because they are worn out and they are dropping the push rod into my head. I bought a new head for my car and had it installed and now the other head is doing the same thing. Please help me. I am the mother of four and I am low income I called chip banks and they will not help me and I have no way to get my kids around. One thing about my car is advanced auto where I got my head from had to special order it because it had a 8 mm bolt pattern so I don't know if that helps answer any questions you may have or not. I gave $13,000.00 For this car and I cannot afford another car and I don't want another car I love my grand prix I just need to know if the heads have been recalled or something. I tried to go on car fax.Com and it said my car had eleven reports on it but I do not own a credit card so I cannot purchase it to find out what has happened to my car. The dealership did not tell me if the car had ever been wrecked or the engine messed up or anything. Thank you. *Tr

Car stalled on me while on a busy road. Ended up being related to the cars passlock system. Cost $500 for towing and repairs. Problem appears to be happening again as car stalled on me while on the road again on 12/11/2007 and would not start up again. Apparently this is a widespread problem on late 90's early 2000's gm vehicles. If this were to happen to someone on the interstate, I would hate to imagine what would happen as everything shuts down on the car (i.E. Power steering). Very dangerous!!! *Tr

I bought a used 2003 pontiac aztec 6 months ago, and found out recently that there is a lot of known problems with the orange anti-freeze eating away at the tubes and gaskets of the engine. We are currently having to pay over $700 to fix this known problem. I think someone needs to investigate this issue and a recall needs to be done. *Jb

Then when it wouldn't start at all, had it towed. The garage I had it towed to had been the one to check the heater a couple of weeks prior to it breaking down, they had given it an oil change also. After the tow, they informed me that anti-freeze had been getting into the intake oil(head gaskets),and they would have to take it all apart(labor!!!)---And that the...

and they agreed. I also feel that I should be reimbursed for the intake manifold gasket and labor since this was obviously not the problem in the first place and they took advantage of me. There is no proof that the intake manifold gasket was leaking, and even if it was, it should be on a recall from gm because it is a common problem for gm motors. When is anybody going to take responsibility for this. *Nm

My vehicle should have fallen under the lemon law due to several problems, resulting in 21 visits to the dealer in less than 3 months. Besides all of these problems, I later had to take it back because when I made a short left to right turn the vehicle would die leaving me to try to steer it to safety. It was supposed to be fixed, but recently it started doing it again. This is a dangerous problem, and is threatening the lives of everyone.I am a single mom, and this is my only transportation.

81,000 miles on it, and is out of warranty. This is obviously an ongoing problem, and I can't afford to have these repairs done.I would like to turn in all of my vehicle information and problems that it has had to someone. I tried to work with the dealer and pontiac's customer service for the first year, and was finally told by walt grayson at grayson pontiac that maybe I should consider an extended warranty. Instead of offering to assist with the situation. I have back up for everything that has been done to the vehicle. Can someone please help me?*Ak

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.
