2012 GMC Acadia: engine stalls while driving

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.

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.

No warning light when transmission went out. Traction control/stabiltrac service light came on, doors locking and unlocking, not stating what gear acadia was in. Check engine light eventually came on, after it stalled twice on highway. Vehicle is at gmc dealership service department and they are saying its not communicating and are checking wiring harness wires. I have replaced transmission and torque converter and now i dont know what to expect now. Only had it for 3 years so far. I almost got rear ended when it stalled twice before backfiring and a rough swift shift.

The car stalled, cut off while pulling into traffic

Was waiting on dealership to catch up to bring in for a transmission problem. I know it is transmission related due to not wanting to shift properly and the fact my friend has same make and model only about 100000 more miles than mine does was doing same symptoms and she took to 3 or 4 mechanics and all said nothing wrong..no codes show up...needless to say after about 2 months it stalled out on her on interstate with speed limit 75 and she barely moving. I myself was at a sharp curve in turn lane waiting on traffic and when I braked to stop it made horrible sound and felt like brake was pushed through floorboard. When I was clear to go i push accelerator down to the floor and am barely inching along and am now stuck in the road in a 90 curve where its hard to see traffic coming. This was very scary and traumatic having this happen. I'm just glad it was only myself and the other drivers were being observant and paying attention to the road. This has happened a lot compared to research on blogs car complaints websites. The common problem is it doesn't give a code when diagnostic checked. 99% of cases show they best guess or find something else wrong and you pay 3 or 4 charges until you finally convince them its the transmission and then you're out 5000. Not counting the average 4500 you've already pd due to not listening to the driver of their vehicle and causing unnecessary charges and leaving you without a vehicle too long that isn't necessary.

When it is parked and idling it sounds like it wants to stall. When I am driving it it shifts hard and the transmission starts slipping. I took it to a reputable mechanic for an assessment of the problem and he said his computer said that it was the traction control module in the transmission and that it would cost about $1500 to repair it including labor. He called the dealer to see if it was in stock and they said they had many of them. I would assume that they would not stock a $700 part in that quantity if they were not having quite a few problems with this part. Other SUV's have been recalled and I was wondering why mine was not. I would appreciate it if you could look into this matter for me and get back to me with an explanation. Thank you for your time as I may be getting stuck somewhere with my wife and children in the car..

After filling up with gas the vehicle failed to start. My husband jumped the car off and once started the check engine light came on with an error code of p062f. Now, it happens randomly but is becoming more frequently in last week' it will fail to start then the check engine light will appear with the same error code, while driving at times it will begin to stall until the gas petal is engaged again. Per the gmc dealership it's the chassis electronic control module however my vehicle year model doesn't fall under the recall, by one year.

Took my car into garage because engine light came on and I almost stalled out multiple times before I made it to the garage. My car was trailing smoke. The code said the timing belt was affected. He said that usually means the whole engine needs replaced. My car just turned 80,000 miles. He said car engines last much longer than that, it should not have anything wrong with it. He told me that many gm motors are recalled, this model and age should've been recalled with as many customers he's seen in his shop with the same problem. I bought my car brand new in 2012, I know how it was taken care of. The engine should not be breaking down just as the payments came to an end. Do the right thing and recall the engines.

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.

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.
