What 447 owners told NHTSA about the 2014 GMC Acadia Denali

Vehicle went from running fine to stalled out instantly. Restarted ok and ran rough for a moment then perfectly fine again. Third time was in a busy intersection nearly causing an accident. Got it restarted and took it to service. The code reported is for the engine fuse box and the part was on backorder. That got me curious so I did a search and see this appears to be a recurring problem including a lawsuit that was dismissed for some reason this Spring. Clearly, this is a problem and a potentially very dangerous one. The more I read, the more I see this exact issue popping up across multiple GMC lines using the same configuration. This needs to be investigated before someone is involved in a major accident.

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.

I purchased my 2014 GMC Acadia Denali July 29th, 2021. It has been back to the dealer five times, with repairs not being completed. Within weeks of purchasing it, the Service Air Bag light came on, and won't go off. The low tire light came on. The serpentine belt broke and had to be replaced, and the power steering pump started making horrendous noises and leaking fluid. I bought an expensive service contract, and of course these repairs are not covered. I also had them repair tires twice, and ended up having to replace the two front tires, after being told there was nothing wrong with them, except one had a screw. They also said that tire rotation was causing the lights to go off, and wasn't reset, and supposedly they reset it to reflect where the tires are on the vehicle in relation to the TPMS's. Well, two tires lost air constantly, and there were numerous leaks. I finally took the vehicle to a real tire store for tire replacement. The estimate for the driver's side airbag system replacement is $1400 pre-tax, and the power steering pump replacement is $1100, pre-tax. So within two months, I've had nothing but trouble; spent $380 on two new tires, and will have the cost of these repairs on top of the extra $2200 I spent on a service contract. The vehicle is beautiful, and seemingly was well-maintained, but it immediately began breaking down. I've had very limited use of it since July 29th when I bought it. (it's now October 6th, 2021). I have a meeting with the owner of the dealership tomorrow, October 7th, at the suggestion of the dealership's repair manager, as well as the salesman.

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.

Tail lights/brakes light/blinkers The light kit cover seals break allowing water into the light kit. Water collects and shorts out the bulbs causing a dangerous hazard when rear lights fail to work in the proper manner. I have called to several places and am being told, yes, GMC has a defect on their rear tail lights. Seals were not done very well and supply cannot keep up with demand. The lights are over 300 each which is absolutely ridiculous. A part that is necessary to keep one safe and be able to signal to other drivers should not be this expensive when the manufacturer did not build a good product.

The contact owns a 2014 GMC Acadia. The contact stated that while her son was driving 40 mph, the vehicle struck a curb and all the air bags deployed. The contact's son did not sustain any injuries. A police report was not filed. The dealer and manufacturer were not made aware of the failure. The failure mileage was 115,000.

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.

THE DASH REMAINED ON AND GAVE THE FOLLOWING WARNINGS: TRACTION CONTROL OFF, ENGINE POWER REDUCED, SERVICE STABILITRACK.

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.

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!
