2012 GMC Acadia: won't start

Filed Jun 24, 2025 · Electrical · MA

This 2012 GMC Acadia denali with close to 160k has been in the shop several times due to it randomly stalling out It kept basically locking me out from starting the car a "service anti-theft system" would flash across the dash followed by a flashing check engine light along with a lock and key symbol. A local GM repair shop had it in 3 times for them to tell me they couldn't figure it out or get the vehicle to "act up" they cut me two new keys and tightened up what they claimed to be loose battery cables just for the vehicle to die/stall with a no crank no start happen literally 10 minutes down the road after paying almost 600$ for repairs and that it was towed back 3 times for the same issue spanning over two months of them not being able to figure out the issue. Salvador ended up replacing the anti-theft control module after the 3rd time having to tow it back and forth just to leave the shop and I couldn't start the vehicle the next day after handing over almost another 400$ and less than 15/20 miles of drive time. GM needs to get this issue figured out!!! There anti-theft system locks people out from starting their vehicles more than it does actually preventing actual theft. This will eventually end up causing a major crash at an intersection or highway if the anti-theft system keeps failing it just randomly cuts out power to the engine while driving.

I was driving along [XXX] . I stopped at Walmart and shopped for about 2 hours. I was Leaving Walmart and was stopped at a red light at the exit from Walmart [XXX] and traction control light comes on and a message came up and stated traction control off and to service stability control and the vehicle loses power right at the light. I checked everything I could and dis connect the battery for about 30 minutes and connected the battery back up vehicle still would not start. After sitting there for 3 hours the vehicle starts up. A week later the same thing happens again. I had to go through all the steps again so after a couple of hours. The vehicle started up. A few days later it happens shin but this time I'm at a stop sign on a busy road. I called Road side service for a tow. No one showed up so I went through Ll those same steps of disconnecting the battery and hooking it back up after a couple of hours and it stated up. I drove it home and started doing some research and found something saying to change the brake pedal position sensor so I done that and it worked for a few days and started doing the same thing all over again. S week later I drive it to the store and got almost home and the vehicle shut down again and would not start back up. I had it towed to my uncle shop Nd he done a diagnostic on it and got about 4 or 5 codes. All of those things are very expensive to purchase. I just ran the Vin to check for recalls on the vehicle but couldn't find any but it should have been a lot of recalls because there are so many of these vehicles the exact same model and year with trouble with stability control ND brake and traction control issues. All the issues they hD on this car thT I have should not have been sold to anyone except the manufacturer. I wish I could just get my money back that I paid for it. $4700.00 not included in the work I had done like the cv axles replace on both sides in the front.

On 2/6/20 after getting into my vehicle and turning on the ignition vehicle wouldn't start so the same day I had my vehicle towed to a certified dealer in union. At the dealer they first stated the ground wire to starter was chewed up so they replaced the starter and then a few hours later they stated no comunication with ECM & bcm. They then stated theyfound water intrusion on passage side fuse block that shorted out the ECM and bcm. At dealer they replaced fuse block, ECM and bcm. Well after $2027.05 later they was able to get my vehicle running again but now the car radio and my onstar in vehicle don't work, also traction control,,stabilitrak , ABS & airbag service lights are on. Two weeks later my car battery died so I replaced dead battery with a new one. My thing is this if all these are issues that people all over are complaining about I truly think all these issues should be addressed and fixed a.s.a.p. Before someone gets hurt or killed. By the way I just brought 2012 gmc arcadia on nov.27,2019 and I shouldn't have to be going out of my pocket trying to get all these issues fixed.

Lift gate would not open, tried to open my driver door to open it from there and it still would not work. Tried to crank car and it made a lot of clicking noises and looked as if the battery was dead but then all of my doors started making clicking noises. Won't start. Won't release key.

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. Was informed with the number of miles on vehicle, 60,100, I should not be having these issues. Car stalled again on september 10 and will not restart. Will need to, again, bring in for service. Complaint is in regard to vehicle recall for my year and model, but not for my specific VIN, even though recall problem exists with my vehicle. Have had car serviced at gm dealerships twice at expense of over $1,000 for the same issue and issue persists. Gm has not responded and gm dealerships have been unable to solve problem.
