2014 GMC Acadia engine problems

“The contact owns a 2014 GMC Acadia. The contact stated that while in park(P), the vehicle rolled, requiring the driver to turn off and restart the vehicle, and the vehicle successfully shifted in park(P). Additionally, the contact stated that while driving at various speeds, the vehicle jerked. The contact stated that while driving 60-65 MPH, the vehicle shut off, and the steering wheel and the wheels locked up. The contact was barely able to pull over to the side of the road, where the contact waited before restarting the vehicle. The contact stated that the Check Engine warning light was recently illuminated. The vehicle was towed to two independent mechanics, where several diagnostic trouble codes associated with the transmission and the transmission module and solenoid were retrieved. The contact was then referred to a transmission specialist, where the vehicle was towed and was being diagnosed. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was approximately 160,000.”

“Engine randomly shuts off when driving for no reason. Will restart and check engine light comes on. Has now happened three times , twice to me in traffic. One of those the car went into a limp mode where it wouldn't drive above 30mph at most. This is very unsafe in the middle of highway traffic. The second happened approaching a traffic light , I put the car into neutral and luckily it restarted and check engine light came on. The third time my wife had her friends in the car and it shut off at a light , she had no idea what to do. I had her stay there and brought her our other car. I have read this is caused by a known fuse box issue. They should be made to fix this problem before someone gets seriously hurt driving in traffic.”

“After I put my car in park my daughter and I were still in the vehicle for a few minutes getting our things with the engine still running. I got out to get something from the back seat, my daughter got out the passenger door and made it to the driver side as I was closing the back passenger door. I was about to get back on the car to get the rest of my things and turn the ignition off but before I could my car was rolling backwards out of the driveway into the street. I was able to jump in the vehicle and put my foot on the brake and the put the gear into Park. There’s no way possible I didn’t put it in Park with me getting out already and my daughter couldn’t have accidentally shift the gear because she couldn’t have been able to get out, close the door and make it to the driver side before it started rolling away. Once I got the car stopped, I noticed the driver seat was now all the way to the steering wheel and completely to the floor with the headrest also tilting inwards and now the electrical for the seat will not work. There is a recall for this issue but my vin# is not included. I cannot even drive my car now because the seat is so far up and inclined.…”

“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.”

“Vehicle is randomly stalling or going into limp mode when driving. Has done it in intersections, driving down the hight way and even stopped in a parking lot. No warning but throws codes unrelated to the problem. I’ve been told that it shuts off half of my engine randomly while running and that contributes to the stall. Can cause accident if stalls while turning or even if in wrong lane on high way. You loose all power steering and basically have to coast to safety. Sometimes it re starts some times your stuck there with no reasons for it to not re start. Usually it starts same day when this happens but hours later. Sometimes it stutters and you know it’s coming but not often will you get this warning. I’ve replaced every thing in every code it’s thrown and still can’t go a week without stalling out. Very unsafe for families just trying to go anywhere. Has done in an hour into a trip or three minutes down the road. All weather conditions as well. I’ve had it to two different garages with no luck yet. Have found a bulletin on wiring for the fuse box which seems promising for the issue but am worried about putting more money into something so unreliable. At this…”

“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”
