The contact owns a 2011 GMC Acadia. The contact stated that the vehicle had drastically reduced speed with no warning. Various warning lights flashed on the instrument panel, the service traction control light, the service stability traction control light and then the engine reduced speed warning indicator as the vehicle drastically reduced speed to less than 15 mph. The contact had to coast the vehicle over to the side of the road. The vehicle was towed to an independent mechanic for further inspection and diagnosis. The manufacturer was notified of the failure. The approximate failure mileage was 55,675.

I was complaining about the performance of this vehicle to the dealer for the past three years. Now that the warranty is expired, I had to change the driveshaft, fell out while transporting passengers; transfer case, the transition from drive, the automatic shift would jerk; a passenger I had in the car told me one day I would not make it up a hill. One week later it happened. Transmission, the vehicle wouldn't move even when gas was applied; 6 coils and plugs, the bad smell of something burning was scary. I had to pull off the road because the reduce power light come on. Yesterday, 12/26/16, I went through this again!!! there is a rubbing sound in one of my wheels, don't know what that is yet. I also changed the axels and about to change the tie rods for a clunking noise while making turns on uneven surfaces. I made numerous complaints to GMC hq and the dealer here in the vi from 2013. The dealer changed parts that were irrelevant and told me it was fixed.

My 2011 GMC Acadia would not start one morning. We put a battery charger on it. It started but has a pinging sound. We checked the oil. The oil was reading low. We added 3 qts of oil. We had auto repair shop change oil and install new battery. I still noticed the pinging sound. That evening, as I was driving the engine started making terrible sounds and loosing power. I stopped driving and had it towed to dealer. They said the engine was blown. I had no warning lights come on at all. The dealer is telling me it is most likely the timing chain. The Acadia is only 5 yrs old with 116K miles. This should not be happening to this new of car. I have spoken to several mechanics and they all say this is a known issue with the Acadia and this should be a recall or warranty issue. Equally frustrating, I bought a warranty that I was told was an "extended warranty" that I thought would lover it now I'm being told the warranty was from the date of purchase which is not what the salesmen told me when I bought it. I feel totally taken advantage of as a women.

My vehicle has 136,000 miles and the timing chain is out, I have had to have the front passenger axle repaired, there is an oil leak. I had the vehicle checked while under warranty because the check engine light would come on, the service department said it was because the gas cap wasn't tightened. Now I have no warranty and the timing chain needs replaced. The first day I drove my vehicle the brake system failed, it was brand new. It had had several recalls.

"tamara recall". I received several notices. Initially auto dealership denied recall existed. Now claims it doesn't apply to my car. Original owner and live in South Florida. What engine the heck is going on" do we have to have a fatal injury to get their attention? engine mounts keep breaking, 16,000 mile intervals. First time dealership replaced. Now at 33,000 miles my phone problem? guess we need catastrophic failure before manufacturer engineers better engine mounts"! low mileage vehicle, careful driver on good roads. Please send feedback.

While driving this morning I had a series of messages appear : "traction control off", then "service stabilitrak" and then very soon after "reduced engine power". the car would still run, but would not go above approximately 20mph and struggled to maintain speed. At one point had to pull over and turn engine off to almost "reset" car to be able to continue driving to destination. This is the third time that this has happened and have had to take to the shop. I have small children that are typically in the vehicle when this happens and am concerned for their safety if this issue cannot be resolved.

The car would not speed up. I was driving on a heavily trafficked road (pendleton pike) in indianapolis, in. After passing sunnyside road, it went from 40 mph to 25 mph in a matter of seconds. I hit the accelerator multiple times, but it would not speed up. I turned my hazard lights on. I panicked! I was barely able to pull into a starbucks parking lot and shut the car off. I waited ten seconds exactly, and then turned it back on. It was fine after that procedure.

Acadia 6-cyl

  • 58,000 miles
While driving at speeds ranging from 30 mph to 60 mph, the engine begins to miss, especially uphill. The vehicle begins to shake terribly. When I contacted the dealership regarding the issue, I was asked if the check engine light was on. It was not but the dealership had me bring it in anyway. This vehicle has been in the shop three or four times now. I have paid to have the fuel system cleaned as well as the spark plugs and plug coils replaced. These are expensive processes not covered by extended warranties. In the end, I have been told by the dealership that unless a check engine light comes on to 'map' the problem, they can't help me.

I'm the 2nd owner and so far I've had to have a motor mount & 2 catalytic converters replaced. The ac started having issues with the controls not working & then the ac completely broke and leaked all the refrigerant which made a huge mess. There's a horrible oil leak that can't seem to be stopped. The brake pedel makes a loud squeaking noise. And now there is some strange noise coming from behind the dash, uncertain if it's the radio, cd player or ac/heat. All these problems at under 80,000 miles!!!

Acadia 6-cyl

  • 73,000 miles
June 11th 2014, it was a Wednesday. I drove over a set of railroad tracks and all of a sudden my car starts beeping and flashing all of these lights at me. The park assist off, the traction control off, the service stabilitrak" and the ?check engine? lights all come on. We are in town and not going very fast so I don?T notice the car driving any differently at first. I stop and still everything seems fine, except for all these lights flashing at me. When I try to go again is when I realized that there is a problem. My car will not accelerate. I have the gas pushed all the way to the ground and my car is moving at like snail speed, I?M trying to make a left hand turn, up a hill, to get to the parking lot but my car literally will not move! vehicles are swerving to avoid crashing into us, I call a tow truck and my finance. When we do hear back from the GMC dealership they basically tell us that we?re idiots. They test drove the car and looked it over and hooked it up to their fancy machines and there?S nothing wrong with it. August 16th. My fiancÉ is driving, on a highway at 65 all of those same lights come on and my fiancÉ announces, ?omg samantha, I think it?S happening again. ? sure enough he is unable to accelerate and the vehicle stalls out in the middle of the road. Luckily for us this time we are on flat terrain and we are able to coast into my mother"S driveway. Because it is so late we decided to just go to bed and deal with it in the morning. In the morning, though, we get into the car and it drives perfectly fine. We drive 6 hours back to rapid city, with no issues, although we are sick to our stomachs. Saturday, September 27, 2014 the exact same thing happens. Dash reeds as this traction control off park assist off service traction control service stabilitrak

My son in law was driving, I was in passenger seat, all of a sudden engine raced, tack needle went very high and vehicle began slowing down all at the same time. Son in law remove foot from gas peddle and vehicle acted normal. This has happen to me approximately 20 times prior to this. Two or three times I took it to dealer who stated the computer didn't 'register' anything. It has happened on interstate when I attempt to pass 18 wheeler in heavy traffic, very scary.
