My 2014 GMC Acadia constantly displays “Service Stabilitrak,” “Service Traction Control,” ABS, brake, and check-engine warning lights. The vehicle will not accelerate past 40 mph under normal driving. Recently, the vehicle began showing “Engine Power Reduced” randomly without any warning, and the vehicle loses power suddenly. The OBD2 code P1682 (Ignition 1 Circuit/Relay failure) appears every time. This issue has caused the vehicle to jerk, lose acceleration, and even stall in the middle of an intersection during rush-hour traffic while my children were in the car, creating a serious safety hazard. These warnings and symptoms are constant, and the power-reduction events occur unpredictably. No official inspection has been completed by the manufacturer. The failed component is still in the vehicle and available for inspection. The malfunction affects traction control, stability control, braking systems, and engine power, putting occupants and other drivers at risk.

2014 GMC Acadia Denali When accelerating the car is sputtering and slipping. The RPMs are increased. There is a delay in shifting and it is rough. The car jerks and has a pause when accelerating. This is an expensive repair. Is GMC going to help or make it a recall? My local mechanic suggests it gets repaired as soon as possible or sell it - am not comfortable selling it with a bad issue. Unsafe. GMC needs to correct this. GMC - do your part and make this right for your customers. I read many complaints regarding this issue. How many complaints does it take before GMC will make a recall on this issue? I also have a recall on the airbag. I have been having an issue with the light on for 2 years and called many times on it. Last year they said there was no active recall. I see now that there is one. I called and was told that I should have received a letter. I never received a letter of the official recall and the repair is covered. I am now waiting 4-8 weeks for the dealer to get the part in and for them to then call me to schedule an appointment. Why do they not have them in stock? I have been scared every time I drive my 2014 GMC Acadia knowing at any point the airbag could go off at any moment or if I was in an accident it may not inflate to save me. This is terrifying as a driver. Especially knowing that serious injury or death can happen. I hope GMC is going to do the right thing and make the transmission issue a recall and have parts on hand at dealers to get repairs fixed. What is GMC going to offer me and other customers to help pay for this serious issue to be fixed? As well as, pay for a rental car while waiting to get the issues resolved.

Vehicle stalls intermittently. Due to an earlier recall of the same model but not including the one I own. There is electrical shorting inside the fuse box in the ignition circuitry that causes this problem. This is a huge problem as there is no preemptive warning. Whether you're driving 5 mph or 55 mph it happens suddenly and without any warning. The incident is stored in OBDII codes. There are no warning lamps until after 5he vehicle stalls out. #PIT5643.

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.
