When traveling at about 35 MPH, all systems failed -- steering, braking, electrical. The dealer indicates that this is a "catastrophic engine failure."
2011 GMC Acadia engine complaints
Page 3 of 3: complaints 41 to 56 of 56, newest first, as owners wrote them.
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.
Tl* the contact owns a 2011 gmc acadia. The contact stated that the passenger side running lights malfunctioned and the vehicle was taken to the dealer. The contact was informed that the headlight assembly melted and cracked, which causing the running light to malfunction. The light bulbs were replaced but the same failure recurred on the driver side light assembly. While driving in the rain, the vehicle suddenly began to hydroplane and the traction control light and check engine light illuminated. The vehicle was taken to the dealer who diagnosed that water was present inside the engine and the number five coil was damaged. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 32,000. ...updated 05/14/15
Ses light came on, trac control light came on/ vehicle lost power. Traveling southbound on state route 83 near wooster, ohio two lane highway with nearly no pull offs. Lost power going up hill. Went from 55mph to barely 20 MPH within seconds.
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!!!
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 fianc is driving,on a highway at 65 all of those same lights come on and my fianc announces, ?omg [xxx], 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.

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.
Driving vehicle, temp gauge got over 240 degrees stopped and found water pouring out of from the front of the engine.after further inspection found the water pump to be leaking badly.
Air condition not working, light on control blinks 3 times and goes out. Could be evaporater coor. Known problem with this model. Why is this not covered under warranty.
Over the past month and a half I have been noticing that when I attempt to push the gas to make my car go faster that it doesn't accelerate. It is usually when my vehicle is already in motion and I attempt to go faster. I can hear it making a noise like it's trying to go faster but there is definitely a delay before the vehicle actually starts to go faster. Usually I am on a normal streets going anywhere from 35-55 MPH (depending on the street and post speed limit), so it's not always a huge deal when it happens. I do a lot of highway driving and this is where my concern comes into play. A few weeks ago I was merging onto 696. There was more then enough room in the first lane for me to safely merge into traffic, however, when attempting to accelerate my vehicle it would not go above 35mph for a good 30 seconds and a car that was in the right lane probably going at least 70mph almost rear ended me. There was another instance when I was merging onto the vandyke expressway where the posted speed is 70mph and the exact same thing happened. Trying to merge into traffic with a post speed of 70mph and my vehicle not going above 35mph is not safe. My vehicle was recently in the shop because my air compressor literally melted and started smoking as I was driving my car. When it was in the shop this problem was mentioned to them and we were told "the problem would be like finding a needle in a haystack" the air compressor was fixed along with the current air bag recall, however, this acceleration issue was not addressed whatsoever. To me this is the most pressing issue and should have taken priority. I should be able to know that when I am merging onto a highway with fast moving traffic that my car is going to accelerate and not potentially cause a major accident.
For two weeks leading up to the 3/27/14 incident, every time we started the car the air would not come on and we would have to manually turn the air on. When we turned the car off, the air would stay on. Two weeks later, when I was operating the vehicle, the gauges on the instrument panel started going haywire displaying dozens of messages, and the all of the gauges would shoot up, then bottom out at 0, then shoot up again, etc.. I turned the car off, and when I came back later to start it, the car wouldn't start but the electrical stuff came on. After several attempts to get the car to start, I roll down my windows and then try it again, and the car started. I drove it straight to the dealership. The dealership replaced the body control module and some wires and said they fixed the problem. Less than 48 hours later, the same thing with the gauges and warning lights happened. We immediately sent an email to the service department since it was the weekend and they were closed. On monday, the car died again, but the radio kept coming on/off....I fiddled with the radio and the car started. I drove it straight to the dealership. They can't get the car to "mess up" again, and are waiting for it to do the same thing it did for me, so they can figure out how to fix it. I am concerned that the car is showing significant electrical problems that include safety equipment, yet gmc is ready to turn the car back on the road. Note: all recalls are up to date and the dealer has been in communication with gmc.
My car skips as if the engine is not getting enough gas. I will be driving along and the acadia will shake and do a little skip jump. It does this at least a couple of times a week. I also have to constantly add oil to the truck even when I am 1000 miles out from my next oil change.
Service stabilitrak, and the engine power low warning lamps illuminated followed by the vehicle slowing to 20 MPH. Vehicle taken to the repair facility where the technician diagnosed that the throttle body was defective and needed to be replaced. This same incident occurred several times previously. Engine reverting to low power is a hazard and safety issue.
While driving on interstate 17w going to deposit, ny, I suddenly saw an error message on the dashboard that read "service traction control", then it read "traction control off" and then the last thing that read was "engine power is reduced". That's when my car dropped from going 60 MPH on cruise control to 20 MPH and I could not accelerate. Thankfully, I was already in the right lane and was able to pull onto the shoulder. At that point, I turned off the vehicle and waited, thinking that the error message would go away and it's just a computer glitch, as this is common with this model vehicle. I started the vehicle again and it had full power but the error message to "service traction control" was still on and alternating between that message and "traction control off". This incident occurred three separate times on the same day along the same highway and at one of the times, there was a large vehicle behind me and thankfully, the driver was able to quickly move to the next lane because I the engine reduced power and I could not accelerate. I put my hazard lights on each time it happened. Thank god my children were not in the car with me when this happened. I have had many difficulties with this vehicle since it was first leased in 2011. I think that all the gmc acadias should be recalled as it poses such a tremendous danger to motorists.
