Driving on the freeway the check stability control warning flashes and the motor gets really loud. Cleaned the ground wires and the motor is no longer making the loud noise or jerking but not my seat heaters no longer work and now the battery light flashes but just 2 months ago I replaced the battery and alternator! all of this happens while driving!

2007 GMC Acadia, service traction control and stabilitrack keeps popping up. It loses the power steering off and on if you drive it in the rain at any speed. Windows can not be controlled by drivers master buttons. Vehicle has 173000 miles on it. Purchased used from buckeye Nissan. Noticed issues right away but their mechanic said there is nothing coming up when they hook up the diagnostics. No warranty when purchased used, this is my first vehicle purchase. I was able to drive the vehicle for a year then got the service traction control and stabilitrack reading and the vehicle would not go over 5 mph. Still paying payments on the vehicle, I could not afford to take it to a mechanic so I purchased a cheap car from a friend and the Acadia sat in my drive way for 2 years. After I paid it off I started to look into repairing it. I put a new battery in it after it sat for so long and it started right up and drove like there was never an issue. I have since replaced the torque converter. Still get engine light and traction control turns off and service stabilitrack reading but has not had it slow down to 5 mph again. Now if I drive in the rain the power steering cuts in and out and is extremely dangerous as it happens at any speed. I have seen several reviews on this vehicle that say the same as mine. The worst part is that GM is aware of these issues but will not assist in repair if the vehicle has over a certain amount of miles on it.

Driving on highway and loss all powers to transmission at 65mph. Car would not move.

- New Haven, CT, USA

Overdrive function faulty in transmission. During cold weather stability trac kicks in and will not regain power even though there is no bad road conditions (such as snow, ice, or rain) it seems to activate when the weather is cold. It barley moves inhibiting normal traffic flow which is very dangerous. Fixed moon roof leaks causing the electrical components to malfunction and rain water drips on passengers and thoroughly soaks the carpets leaving a mildew smell.

While driving at 55 mph three warnings came on "reduced engine power" "service stabilitrak" and "traction control off" then, the speed began to decline and I could not go more than 35 mph. Got the car to a safe place to stop and when I put in park a sputtering in the engine could be felt. I turned off and when I started it to bring it in for service it ran fine but check engine light was still on. A very similar incident occurred just over a year ago. Repair was to replace the throttle body. Also mention of the tps sensor on the throttle. I have not had the current issue fixed yet.

Bought this vehicle in 2010 with 89000 miles in 2013 timing chains went out took to GMC dealer and even though this was a recall about the timing chains cardinal in hazard ky would not fix this recall because they said if the vehicle had over 120000 miles the recall was expired..so timing chains go out and I read from this site the recalls never expire ?? no the vehicle has major problems

- Jackson, KY, USA

Within 24 hrs of buying the vehicle my exhaust system fell off going down the highway. All the lights but the check engine light works on the dashboard. When you stop or accelerate the driver's seat moves forward or backwards slightly. Traction control does not work after the second week of owning it. When receiving for loaner vehicles all of them did not have working engine lights.

- Oconto Falls, WI, USA

The contact owns a 2007 GMC Acadia. The contact stated that the stability and traction control independently turned on and off and the indicators for each illuminated on the instrument panel. The contact stated that the vehicle jerked when coming to a stop or making turns. The vehicle was not diagnosed nor repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 114,000.

While traveling down highway, car displays message "service stabilitrack engine power reduced". car slows down and shakes. Turning car off for a few minutes then turning back on clears issue, however, happens multiple times daily. Very dangerous while traveling on highways or freeways.

2007 GMC Acadia...it has 62000 miles on it & just in March we had a problem with a metal on metal scraping sound(& you could feel it when you braked) like it needed new brakes but brake pads were like new. And the service airbag light is on, then service traction control message, & service stabilitrack message came on too & it started jerking when you hit the brakes like the ABS brakes were kicking in. So we took it to robinson's & they turned the rotars & rotated my tires & when I got it back it rode like a dune buggy. Took it back & said it needed new struts cause "something" stayed in a locked position or another. So then we got it back & the scrubbing noise/feeling came back with the brakes again so then they finally just put new brakes on it & so far so good $1000 later! now, this morning I was in a drive thru & it felt like my car was in neutral when I tried to go forward & I had to look to see if I moved the gears & then I noticed the orange engine light was on. It barely wanted to go & the rpms just kept getting higher & higher & it was struggling to move so I pulled over & had onstar run diagnostics & codes PO700 & PO716 power train detected malfunction transmissions & transmission not performing as expected!! I noticed after she ran the test my car sounded like it changed back to normal while running so I cut it off & back on & it drove ok back home but now we have to have it looked at & I'm just sick to my stomach over this! it looks like it's gonna be a broken wave plate & ending up resulting in a new transmission I can not afford!!! I know it's 2007 but with such low mileage & in great condition I wouldn't think it should have all these problems especially with the transmission!! I have read so many reports on the same issues which are beyond ridiculous considering how much you pay for these vehicles!!!! this is totally unsafe & needs a recall asap!!!

My car would not go over 40 mph on a highway and the rpms were shooting up to 9,000. I safely made it to a parking lot and when I went to leave the car would not move in reverse! I had to push the car, with my 5 children in it, out of the spot!! (I'm a tough chick but this was crazy!). I got the car out of the lot and was able to slowly make it home. My car is only 10 months past warranty and we will be stuck with a big bill. I think it should be covered or GMC should reimburse the repair fee.

While driving on the interstate, I had to brake quickly because of accident ahead. At this time, the stabilitrak service message and brake message started alternately flashing on dic. Brake and stabilitrak warning lights also came on. The car decelerated like when you shift down on a manual transmission when I tried to accelerate again, no response. Tried turning stabilitrak button back on and off, but this did nothing. After a few seconds the car started to accelerate, the engine light came on. I was in heavy traffic and was difficult to get over to shoulder. I had about 10 miles to get to my house, so watched the engine temp gauge, and made it home. Engine light remained lit. The engine gauge indicated the cars temperature rose about 15 degrees above what it usually is.started the car the next day without any warnings or messages displayed and took the car to my mechanic, he ran the codes on cars computer. It showed no errors, was a little low on water. He said to drive it and let him know if it happened again. The vehicle had been in operation for another 45 days, with no more signs of problems. 46th day, the vehicle's service message for stabilitrak and brake flashed again, with warning lights for these coming on as well, after car was driven approx. 4 miles and parked for about an hour. The vehicle operated fine. I parked the car again for about one hour, warning lights came on after about a mile the next day the same episode. Now I'm into the 2nd week of the brake and stabilitrak warning lights coming on and off. Will call the dealer because at this point I'm afraid of another gear down like the first incident and being in heavy traffic-that's not safe however, I've been to the dealer before about the passenger airbag sensor saying it's off when there is a passenger sitting there. Checking cars computer said "codes? showed nothing wrong? are the "codes" infallible"

My 2007 GMC Acadia has always had very poor traction on wet roads and sometimes on dry roads. Yesterday I was driving on the freeway in heavy rain when the steering wheel suddenly jerked to the right as though my right front tire had run over a large object. A few minutes later it jerked right then left then right again. Each time the steering wheel would lock for an instant. I found myself partly over in the other lane. A very dangerous situation. I didn't notice any warning lights. This problem occurred twice more before I realized that it seemed to be happening only on upsloping parts of the road or when I tried to accelerate. As I had always suspected, the traction control system on this car is faulty and dangerous. Faulty power steering cold also be a possibility. I tried to drive home at a steady speed and had no further problems. About a year ago I told my local GMC dealer that I thought the car had very poor traction and the system should be looked at. They told me they checked it out and there was no problem.

2007 GMC Acadia produced message stabilitrack off. The car started to slow. Looked in owners manual, it said to pull over shut off the engine and wait 15 seconds and restart. I did that but waited 25 seconds tried to restart, nothing happened. When this happened all the gauges malfunctioned and the engine light came on. Was towed to dealer, dealer did diagnostics, and said could not find nothing wrong. This happened once before without the consequence of not starting. Just came off of the expressway 10 minutes prior to this occurrence.

2007 GMC Acadia all warning lights come on and sterring gets very hard to turn. This is third event since Oct 2009 and the dealership has "fixed" it each time.
