Owner reports
Selected complaints filed with NHTSA by 2012 GMC Acadia owners, lightly cleaned up (personal details are redacted by NHTSA).
I was driving 40 mph, when warnings appeared on my dash. "Service Stabalizor control", "Traction control turned off", "power is reduced", and the check engine light came on. I lost power as if engine quit, no acceration, but then came back intermittent. If I had been on a highway going 65 mph, in heavy traffic, there may have been an accident. Power steering remained on. I took to an auto service business, and they were unable to find the problem. Code indicated a fuel pressure problem.
My 2012 GMC Acadia has had numerous issues that all lead to the fuel pump assembly. Three separate times, my cars ignition has just shut off while driving. When trying to accelerate from a stop, the car will struggle to move then jump forward nearly hitting the car infront of me. Stabilitrak warning comes on. Car randomly jerks while driving. Car will randomly not want to start but eventually does after multiple attempts.
Ratle sound in the engine thinking it may be the timing chain. Code p0430 came on stating catalytic converter bank 2 needs replaced. We replaced o2 sensor downstream on bank 2 code was cleared by shop. After driving a few miles same check engine light came on and i took it to the shop they hooked it up to run the code and it was the same p0430 again
Automobile stalled while driving and would not start. Service completed at Chevrolet dealership on June 12 to replace fuel pump control module, which was a recalled part on GMC Acadia's. I called GM and was informed my VIN was not part of recall and was told I would be called back with an explanation why. I never received a return phone call. Car stalled again while driving and would not start. Service completed at GMC dealership on August 12 to replace fuse block that controls fuel pump. Approximately 2 weeks later car stalled while driving, then restarted. Returned car to Chevrolet dealership for service. They held car 8 days but could not find source of problem, though thought it was the fuel pump. Car stalled again on September 8 then restarted. Brought to Chevrolet dealership for service but again they found no service code. …
Chassis electronic control module internal contamination - GMC recall 14515 - this is a recall on a lot of GM cars and trucks which includes the 2012 GMC Acadia but my VIN doesn't qualify. This control module is exposed to water and all of the elements which is why there is a recall. Ours failed yesterday at highway speeds and the car died at 60 MPH. We were lucky to be heading to the exit when it died and not involved in a crash. I've spoken to 3 GMC service centers in the area and the GMC assistance center and they tell me that my VIN does not have any recalls. Very dangerous situation that occurred and all of these vehicles need to be fixed.
Today with the fuel gauge showing 1/2 tank full, my Acadia ran out of gas and I was forced to the side of the road. I have seen recalls for other year models for this exact problem, but the year my Acadia is does not matter to GM. This is a very serious problem that could cause a severe accident. GM's recall number is 14007. In the affected vehicles, the engine control module (ECM) software May cause the fuel gauge to read inaccurately. An inaccurate fuel gauge May result in the vehicle unexpectedly running out of fuel and stalling, increasing the risk of a crash.they know there is a problem why not fix it.

2012 Acadia needed a replacement of the number 2 fuel injector in 2015, number 4 in 2016, and at the end of 2017 required all 6 replaced, plus the fuel pump. All 3 times these issued occurred while I was driving on the freeway when the vehicle warnings of service stabilitrak, service traction control, and reduced engine power started going off. The car then began to smoke heavily from the exhaust pipe and it was required to limp off the freeway, praying that I wouldn't be hit as I went from 75 to 40 in seconds.
