I have had the same problem for 3 years now and have taken my vehicle to a GM dealership many times for the same issue and it is definitely an issue. My car keeps throwing up TCM issue and ECM and I have asked for the modules to be checked. I have reasearched these issues and it seems to be the same with many vehicles like mine so that should be a red flag. My car will slow down, power reduce engine, traction control off, and my steering will be difficult and sometimes I can-??t even get off the road in time, which is very dangerous. I have seen recalls on electrical issues and wonder if my vehicle has damaged recall parts. I am a single mother who has to work and get my child to school and can-??t do so properly with my vehicle doing this all the time. It-??s very frustrating.

My wife was driving at highway speeds (70MPH) on the interstate in Chicago when without warning her cluster lights appeared and her vehicle lost propulsion (stalled, Stall, died). She had no warning and the area had no shoulder for her to pull off into so she had to come to a complete stop in the right lane of the highway. People are doing speeds well above 70MPH, I would hate to think of what could have happened if a person or line of vehicles could not change lanes in time; very serious injuries and possibly death for all invovled. Fortunatly, she had the sense to put the car in park (highway lane) and completed a key cycle thus restarting the vehicle and then obviously accelerating quickly to get out of harms way. As people are swirving out of her lane and honking at her. I put our VIN into the NHTSA site and see the vehicle has no outstanding recalls. Then i search just the model year and come across a recall (14V-614, GM recall number 14515) that appears to be the same issue we may have had. In the vehicle information section of the 573 it lists: Descriptive Information : 2014 GMC Acadia Production Dates : JUN 27, 2013 - SEP 26, 2013 Plugging my VIN into a VIN decoder, i see that my vehicle was built July 26, 2013; this falls within the suspect time of this recall. Why have I not been notified of this recall" Why is the NHTSA tool not show my vehicle as being affected" This could have been a very a tragic ending. I hope you (NHTSA) reach out directly to GM to figure out why my vehicle was not included in the recall. Why my wife was put in harms way.

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.

Air Bag Service code shows up. It can be removed briefly by moving the seat back and forth. I did some research and this is similar to the recalls for older years previously issued with the wiring harness causing the air bags to malfunction. This is extremely dangerous and is well known on many car complaint sites. Why has nothing been done? Thank you.

My fuel gauge occasionally registers as empty even after I fill the gas tank. This typical happens if I let the fuel go below 1/4 tank. This has happened since the first 30,000 miles and I was told by the dealership there was no recall or safety alert for this condition. It gradually goes up as I drive. It is my understanding this is a common problem with this vehicle and model year.

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.

My Acadia has shut off without warning multiple times. Today, I was in a parking lot picking up a prescription. The car was idling while I was waiting in the pick-up lane and then shut off. The dash remained on and gave the following warnings: Traction control off, engine power reduced, service stabilitrack. I tried to restart the engine only to have the car shutter violently while idling. I turned the car off again and then restarted for a second time. This time it restarted as normal and the check engine light came on. I have taken it to a dealer 4 times since October as it has shut off while driving and making a turn. The dealer says there are no codes in the diagnostics and cannot find a problem. I'm terrified to drive the car. I saw a recall from 2014 about an electrical short but I don't know if that was already fixed on this vehicle since I bought it used. I also don't know if this is even related to that recall.

Service side blind detection started going off then the side blind detection stopped working completely. Now the entire electrical system is not working correctly and was told the side blind detection monitors can cause the entire electrical system to malfunction.

Traction control sensor turns on-service stabilitrak-engine loses power-car dies while driving at any speed. Turn the car off wait for awhile and sometimes it will turn over and everything is fine. The issue is slowly happening more often and taking longer to start back up.

Car shut off while driving. All electrical went out. Doors all locked while inside, key stuck in ignition. Started with side detection warning and within a few days car completely shut off while driving! huge safety issue! will not restart and still can't get key out of the ignition. Battery is fully charged but no power. Completely dead. There is a known recall on 2014 GMC Acadias for electronic module failure but not our specific vehicle though this seems to be the exact cause of our problems. GMC said they could not help?!

While driving on the highway my car began shuttering and the warning system went off stating the traction control had gone off. Then it said engine power reduced, service engine, and service traction. The car began shaking and immediately slowed down. I pulled over and turned off the car. Upon restarting the car I received a message that said traction control on. But the engine light came on. This is the second time this has occurred. The first time it happened I took my car to the dealership to which they said they couldn't find anything wrong with it. After doing a google search today, I found that this seems to be a common problem in GMC Acadia and I am shocked that it hasn't be reported/recalled. In retrospect, I have noticed that sometimes when I accelerate, the car will fail to shift gears in a timely manner and jerk forward when it finally does so. I was on the highway with all three of my children in the car when this happend!

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

Engine reduced power. Vehicle will no longer start. I was driving and lost power while driving. I pulled over even though power steering was not working.had car towed to conley automotive, wimberley, tx. Diagnosis from conley said faulty fuse box. They said it was a technical service bulletin problem. I input my VIN# on NHTSA and foind recall on ECM, electronic control module. When I spoke with the service dept at chuck nash Chevy dealership, they said no recalls were noted on my vehicle. I am extremely upset that this in fact is the issue with my car. How do I add my vehicle to the safety recall?

- Wimberley, TX, USA

The electrical issues continued despite hundreds of dollars checking various problems. The fuse block was replaced and for a month things were fine, but the car is still experiencing constant check engine light, difficulty starting, doesn't stop right away when turned off, random stalling, you name it. It feels like a death trap.

Side detection system malfunction

- Richmond, KY, USA

The module for the side blind zone alert notification system, back up camera, tv's/dvd's quite working after it went through the car wash. When taken to the mechanic it was said it module was filled with water. Attempted to have this address in April of 2019 and now other things are getting worse! side mirror lights always on.

- Newton, IA, USA

Side blind zone alert module failure. Side blind zone alert is intended to signal the driver of objects in the blind spot when changing lanes. This 2014 Acadia has a malfunctioning module, resulting in the alert light remaining on in the side view mirror. There is also an error message in the instrument panel. GM refuses to apply existing N172097060 special coverage adjustment to this vehicle, despite meeting the make, model, year, and specific problem related to the module.

First, 2 days after we purchased the car, the engine light came on. Then the front camera needed service and the side warnings stopped. Then the seat heaters quit. The fobs both quit working, would. It properly unlock the doors. We got an airbag needs service warning. A check gages warning. A service tire monitoring system warning. Finally, the engine locks up and won't start, turn over, or anything. Several hours later, the car starts. Then it goes through the whole cycle again over the next few weeks til it doesn't start again and leaves us stranded. Again. The first time, the mcdaniel GMC service department changed out the battery and believed that would fix it. We paid $190 for that. It didn't work. It went through the same cycle again within a month. Now they expect us to pay to have he module fixed, even though they knew there was a recall for it when hey sold it to us.

There is a known problem with the control modules for the driver safety/assist systems and GM sent a letter indicating that they would repair vehicles that met a certain mileage and age criteria. My vehicle did not meet these criteria. The fault drained my battery and I had to have it replaced and the dealer indicated it could be $5000 to fix all the other issues associated with the faulty control modules. As a result, my wife has now has no blind spot monitoring/indicator, the forward/rear crash monitoring/alert system doesn't function and all of the the other proximity/safety systems don't function either. In addition, other electrical issues are now starting to surface and the garage door opener no longer functions. I am scared that this may lead to a serious electrical malfunction, short, or fire that could cause a serious safety issue. As a result, I recently purchased a new vehicle for her but I am now driving the impacted vehicle.
