What 447 owners told NHTSA about the 2014 GMC Acadia Denali

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 many problems relating to this vehicle, for only owning it for a year. Inaccurate Fuel Gauge Reading- My fuel gauge is inaccurate. 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). I have taken to many shops, 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 with no good reason/cause. My vehicle was difficult to start and would require several attempts before starting. Power lock/unlock fob doesn't work, replaced battery multiple times. My windows and sunroof power windows do no work and unable to fully close on/off at times. 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, some have not been able to pin point the problem for some of these issues or have been charged unaffordable amount before fixing, and only diagnosing problem. There are recalls out for many of these problems and my vehicle needs to be on the list for serious safety issues!

While driving at 70mph legal speed limit the engine lost all power and ability to brake or steer with and power assistance, mechanic has since told me the timing chain failed and destroyed the engine. Vehicle had aproxmitly 99k miles on it and in good repair. No warning that it was going to fail and was told that this is a common failure with the engines in most gmc / chevy / buick mid size svu.

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.

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.
