2014 GMC Acadia: sudden loss of power

Filed Sep 15, 2025 · Acceleration, Electrical · LA

Got onto the interstate and suddenly my car stopped but didn’t kill. My traction control light said off and then it said reduced engine power and my fuel went down to E. I couldn’t go but my car was still running. I killed it then waited a minute and started it again and it started moving slowly. Then it said service stabliltrak and traction system but since the light have went off. Around the same time I started hearing popping and crackling sounds from my speaker and now I have no interior sound at all just popping sounds no matter if my car is started or not. I’m scared it’s going to catch on fire or something

I have taken this vehicle to 2 different mechanics for "stuttering" during driving. Many times it will state a problem with stabilizer and lose power causing me to pull over in traffic as soon as possible. When this happens in snow it has become dangerous. Lately it just stutters without stabilization. No one has been able to find problem and sensors have already been changed. These occur at speeds of 2 mph to 75 mph intermittently

I have been having the same issue with my car for 11 months now. My car has been in the shop more than in my possession. I have paid for repairs that did not solve the problem as well as thousands in car rental fees. When I am driving my car at over 70 MPH on the expressway the dash board lights up with a check engine light and then reads traction control turned off, service stabilitrak and the reduced engine power. The car then reduces down to just over 30 MPH right in the middle of the expressway. I've barely missed several accidents that could have killed someone. I have been in and out of the dealership as well as contacted GMC directly. This seems to be a common issue in this make and model of GMC (2014 ACADIA) and I am getting no where with any help or compensation from them. I was just quoted today for another almost $1900.00 repair that may not even solve the issue. I am still paying on this vehicle and am a front line worker who relies on this vehicle as I am a traveling Occupational Therapist. I don't think it's right that big business can just run over the little guys like this, not to mention the safety aspect and possible death can result in this issue. They have also not fixed the recall on the air bags which can lead to death as well. Please tell me there is something can be done about this.

My wife was driving our 2014 GMC Acadia to work. She stopped to fuel up her car about 4 miles from home. She left the gas station and proceeded to head to work. She called me (her husband) in a panic because she had lost all power steering and could not turn the wheel through an intersection. I asked her if she had made it to work and she said she was about to pull into the parking lot, but was going to have to park aways out from the building as she couldn’t turn into a park spot. I went and checked out our car when she was inside working and sure enough the cars power steering fluid was all over the ground under the driver side of the car. I trailered the car back home where I could get a better look at things. The rack and pinion had failed without any warning and was spraying fluid out of the top of the rack. No warning lights or indicators on the dash, warning of low fluid or anything malfunctioned. Still when you start the vehicle there is still no warning lights of low fluid or anything. Of course we are dealt to deal with the repair and expenses ourselves because the extended warranty we have doesn’t cover anything to do with steering components with our car that we have owned now for 1 1/2 years.

First problem is the trunk door. About a week ago I was getting something out of my trunk and accidently hit the button and the door started to close so i tried to get away from it and somehow my arm got caught and there is absolutly NO sensor to stop the trunk from crushing my arm. Unforunately, i did have some injury to my arm from the trunk coming down and have pictures of the brusing on my arm. A sensor to stop the trunk from closing on a body part or anything for that matter needs to be better made or put in the vehicle. I took pictures of my arm days later because i was in to much pain to take them when it happened. It was not a fun injurying. Saturday night iced it, sunday had to have it elevated because it was so swollen, didnt take the picture until Wednesday when it finally had calmed down. There is bruising and swelling still on Wednesday. this happened July 9th Second problem i recently had an issue with my wiring i guess it was. Specifically it was reduced engine power message displayed and my engine stalled out on me. I was told that this is a common problem with Buick Enclaves, Chevrolet Traverses, and GMC Acadia's which is the car i have. Being that this is a common issue wouldnt this be something that would be concerned a RECALL? i dont know how recalls so im more curious about it. my car stalled out on me in the middle of traffic on July 16th

While traveling approximately 75mph the Service Traction Control light came on followed closely by the Low Oil Pressure Stop Engine Immediately light. We attempted to travel to a more safe area along the interstate. Within seconds the engine immediately shut off causing the loss of power steering and power brakes. The steering wheel locked in place causing the total loss of steering control. We were able to bring the vehicle to a safe stop, I would attribute this success to my being a Defensive Driver Instructor and Transportation Safety Professional. The risk associated with the issues we were faced with could have easily ended in tragedy especially at this speed (75 mph, 80 mph zone) The diagnosis of the vehicle was inconclusive due to the number of codes that were shown. The vehicle was no longer functional and had to be replaced. No documentation, other than the bill for towing is available. Diagnosis was done at no charge.

A code p1682 -ignition switch circuit will pop up. I've had the problem for a year, the vehicle will seem like it doesn't have a lot of power at times. The engine light will come on, reduced engine power and traction control off. The battery voltage drops below 13 . I have changed the battery, alternator, throttle body, gas pedal sensory. It does all of that while driving, and starts to stall on me. That code popped up once last year and I took it to the shop and they said it wouldn't come up and it's doing it a lot more. I have did research and have seen many issues with a fuse block and ignition switch.

When turning on the car it immediately gave a check engine light, began violently shuddering, and ran "service stabilitrak" "traction control off" and "reduced engine power" warnings. We have taken it to 2 different dealerships and they keep telling us nothing is wrong with the vehicle. We have even called gmc service line directly and explained that this occurs while we are driving the car and the vehicle will sometimes completely shut off. This time the vehicle was parked and initially turned on. We restarted the car and it took two tries before it appeared to start "normally." the check engine light is still on.

While driving coming to our destination stop, at bout 1000ft left, my 2014 acadia just started shaking, and misfiring and losing power. On the steering column, the notification states, traction system light came on, and check engine light. We then came to a complete stop and put in park, then started driving again and went off after 2-3 minutes. Then powered off and check engine light remains, and others off.

2014 gmc acadia went abruptly into what they call limp mode. The engine lost power, with a massive shutter throughout the vehicle, numerous warning lights on dash, saying reduced power, low voltage, traction control/stability control and check engine light. I have done some online research and seems to be a big issue for the acadia! A recall to general motors is in order so all these safety issues get addressed as soon as possible. There are stories that the dealers have fixed them but a week or two later the issues returned. Please help us
