2014 GMC Acadia: engine stalls while driving

Filed Nov 16, 2025 · Electrical, Engine · OR

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 point it’s dangerous to drive and is a safety hazard.

Fuel gauge is incorrect. It says I went 20 miles when I only went two. Then when car is in park the gauge goes back up but when moving the gauge goes down quickly. This had caused me to run out of Gas when I shouldn’t have and it’s adding miles to my odometer that I never went or it’s fluctuating and that’s faulty. the federal safety agency CAMPAIGN NUMBER: 14V223000 Inaccurate Fuel Gauge Reading An inaccurate fuel gauge may result in the vehicle unexpectedly running out of fuel and stalling, increasing the risk of a crash. the federal safety agency ID Number: 14V223000 Manufacturer General Motors LLC Components ELECTRICAL SYSTEM, FUEL SYSTEM, GASOLINE Potential Number of Units Affected: 51640 Summary General Motors LLC (GM) is recalling certain model year 2014 Buick Enclave, Chevrolet Traverse, and GMC Acadia vehicles manufactured March 26, 2013, through August 15, 2013.

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 many problems with this vehicle, numerous times. Inaccurate Fuel Gauge Reading- It has resulted in my vehicle running out of fuel and stalling, while on road. I have 4 children who are at risk of danger while in vehicle.The fuel warning light has illuminated when the gauge needle says I still have more than plenty of amount (a quarter of a tank or more at times. It differs). It was diagnosed with an electrical and fuel system failure. Electrical shorts and problems- Having electrical shorts on and off. Check engine light comes on/off Vehicle randomly failed to start. My vehicle was difficult to start and would require several attempts before starting. Power lock/unlock key fob doesn't work, replaced battery multiple times.windows and sunroof power windows do no work. Radio and dash turn off and restart. Check airbag light has been coming on and off. Power Train intermittently, the transmission shifts with a loud thump, at various speeds. Vehicle starts shaking and jerking while shifting gears and going different speeds. My vehicle slows down, power reduce engine and steering difficult at times. Other/ water leak- Found water in all of my tail light assemblies, headlight assemblies, sunroof and windows leaking. There is no proper seal or has worn off, causing leaks in and repairs for many replacements, which are expensive temp fixes with no permanent solution. Causes accidents by not having necessary working equipment for driving conditions. Other:Hood doesn't latch and stay open so difficult to even check fluids properly alone. Multiple dealers have inspected problems, and needs to be fixed. There are recalls out for many of these problems and my vehicle needs to be on the list for serious safety issues.

On 3 occasions vehicle will shut off while driving down the road. When restarted goes into limp mode. Have at repair shop now and they stated there was a campaign on the electrical fuse box but my Vin is not included. This is a complete disaster waiting to happen on busy roadways. Waiting for the parts to arrive so they can replace it, stated they see wires arcing. This is a $1000.00 bill that is most definitely a safety issue, perhaps someone jumped the gun on which Vin numbers to include. I am fortunate that I wasn't on the interstate when this happened. Very upset.
