2009 GMC Acadia driver assistance complaints
Page 2 of 2: complaints 11 to 15 of 15, newest first, as owners wrote them.
Vehicle had a slight misfiring when climbing incline. We replaced two spark plugs. Misfiring calmed down. A couple days later misfiring resumed. Husband was driving daughter to daycare when car had multiple dts codes appeared (stability track, check engine, reduced power) with car suddenly stalling while on a highway leaving barely enough time to coast off the road and out of the way of traffic traveling 60mph. Gmc refused to assist us on this issue until we found online a tsb about the timing chain which had broken. Due to the constant misfiring (direct result of the timing chain) two of my catalytic converter became clogged. Those have now been replaced out of my pocket however when driving vehicle home while it does run smoother it now misfires all the time even when not going up hills and idling very low and misfiring while idling. I am scared that while driving my vehicle this may happen again because the issue has become worse.
As my wife pulled out of the driveway, she heard a "clunk" noise, and she had to apply a lot of effort to straighten out the vehicle. My wife has stated that this is almost a common issue with the steering and many times she has to use a lot of force to steer the vehicle in a straight line. We took the vehicle to the dealership who stated that this is a common occurrence and that it would cost $400 to repair this problem. We declined the repair and felt that this was as safety issue and that it should be repaired without any costs to us. We have filed a complaint with the general motors company however we have only received a form type e-mail indicating that our complaint is in their files. We have also information from other web sites that this is a common issue, however nothing has been done at a federal level. We only have 35,000 miles on this vehicle and now we are really afraid to take any kind of long highway trips for fear that this would happen at highway speeds and that this may result in serious injury and or death of ourselves and our loved ones. Please advise as to what other actions we can take to resolve this safety issue. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)
First problem was the timing chains needing to be replaced at 18000 miles. After that repair was made the gas mileage was averaging 11 mpg. It was a one year old car! After that, it was a multitude of problems. Steering rack/power steering replaced and 'fixed', electric stabilitrak lights going on and off, dvd player not playing properly. All things the dealer had said they fixed (after they whispered that I should not have bought an american car.) now the transmission is acting up. Rolling down an incline when I was trying to back out of a parking spot. The dealer told me it was fine and they could not duplicate the issues I was having. I've written two letters to gm corporate to complain about the sub-standard vehicle. They were helpless and will not assist in any replacement of the car. They even told me that this would be a difficult car to trade in considering the problems I have had with it. Who is kidding who? I would never recommend this car and hate to continually put my family in it .it is unsafe. Period.
I believe I have some type of electrical issue. I started testing different parts of the dashboard lights such as the driver seatbelt. I purposely drove several miles in my neighborhood with the seatbelt over me, but not engaged and the light did not come on. My airbag service light came one for service, they serviced it, it came back on, they replaced a seatbelt component, the light was off, but came back on, they did another replacement and the light is now off. My frontend was making funny noise when making turns, they replaced my rack and pinion. My service stabilitrak light, service traction control light came one, they fixed it, they came on again, they kept my vehicle for a day and fixed it. They are back on again along with the ABS light and now I'm told that I probably need a break job. Breaks were not mentioned the other times. My electronic key pad deteriorated and no longer works, they said it was user handling, my other key pad is not malfunctioning, you can see were the pad is begining to sink in, but they said it's my handling. The case is chipped and the chipping has occurred in the same place on both key pads. My middle seat passenger side case came apart twice, each time they fixed it, it's now broken, and I was told they don't repair broken parts. I am still under the bumper to bumper warranty, but gmc will not replace my key pads, and the service tech says he will try really hard to get my seat covered. The tint on my windows have been replaced three times and still is not correct. My dvd player does not play correctly and has not been fixed since it's been in my vehicle. My vehicle is a 2009 acadia. I had a leak in the trunk, they fixed that. Air pressure will not stay consistent, was told by service advisor to over inflate to compensate, which is different from what the owners manual states. Tire pressure issues needed sensor replaced after several trips to service department. The vehicle is an expensive piece of junk.
