The automatic passenger side window does not work anymore, it went out a couple months after I bought it. I have always done maintenance on my vehicle, oil changes, tires, etc. and the timing chain went out on it for some unknown reason. Very pricey to fix. I would hate to be stranded with my 6 grandchildren with. With all the complaints on the timing chain, this should be a recall.

We just purchased this 2012 gmc acadia about 30 days ago and every day we drive it we have this issue.. from a complete stop when pressing the gas the truck feels like it has no power starting to go until the rpm-€™s each maybe 4500 then the truck will jerk and studder through the intersections. i feel like we are going to be in a MAJOR accident while proceeding through intersections. the dealer states there is nothing they can do. there is absolutely something wrong when it jerks and stutters to move

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..

My 2012 Acadia only has 112,000 miles on it, and I am having transmission issues. It started as a vibration (washboard sound) for about 5 seconds when you were traveling at 55 to 65 mph. I have had my vehicle serviced regular. After having it in the shop 3 times for the same vibration, I was finally told it could be the transmission. It is sad that I have such a nice vehicle and will have to trade because GM will not do anything about the faulty transmission. To replace the transmission it will cost at least $5,000. This could keep me from purchasing another GMC. The problem is on going unitl I decide, repair or trade.

The torque converter is failing per dublin GMC. That is the cause of the stuttering. In addition, the rear lift gate has failed and will not stay open in either power or manuel mode. Apparently my vehicle manufactur date is out side the recall months for this recall (per dublin GMC and self check on this website) recall # 5420 and nhst #15V415000. How do I get the mfg to pay for this potentially lethal failure (it almost got me when it failed as I was taking groceries out of back)

The transmission is slipping or shuddering under certain conditions. Most frequently noticeable around the shift points between 2nd&3rd, or 3rd & 4th, especially when the engine is downshifting to climb a hill. There is a strong vibration and RPM bounce a bit before it finally engages after a couple seconds. I have recently learned that Acadias have a long history of transmission problems, notably the torque converter and wave plate.

The contact owns a 2012 GMC Acadia. The contact stated that three days after the vehicle was purchased, the contact was unable to start the vehicle. The contact also stated that the check engine warning light later illuminated. The vehicle was taken to kindle auto plaza Ford (523 stone harbor blvd, cape may court, (609) 465-5000), where the starter, the timing chain and the transmission were replaced.

The sensor failure recurred several times and the dealer referred the contact to the NHTSA. The manufacturer was not made aware of the failure. The vehicle was not repaired.

Well GM strikes again. I just submitted a transmisson with my 2014 Silverado but it looks like my 12 Acadia has the same transmission issue. We bought this Acadia used and within the first year of owning the transmission failed due to a known issue by GM. I almost got rear ended today because the transmission shuttered significantly enough that the car wouldnt go. I am extremely annoyed. I think its time we go to another manufacturer...the 35R clutch wave plate is junk and sends metal throughout trans and destroys it.

The car sputters and hesitates when changing gears. I took it to a GMC dealer and found out the torque converter and transmission were bad. I researched and found multiple complaints of this happening with the GMC Acadia. I received a price of approximately $4500 to correct the issue. I did contact GMC and was told no assistance would be offered.

While driving at highway speeds last week my 2012 AWD Acadia having a major malfunction. 1. while driving, door locks engage/disengage 2. trans appears to slip into neutral (high rev/ no power) 3. on the dashboard digital readout the transmission "blinked" into P from D (while driving) 4. traction control engages/disengages and the vehicle lurches forward and hard stops 5. trans enters some sort of limp home mode where it allows me to drive only up to 60mph, @4000 RPM (like 3rd gear) this process repeated continually for over an hour drive to the dealer, normal operation appeared to occur at speeds below 45mph, but only temporarily and the issue continued again at the lower speeds. I call onstar and they pull codes for me while enroute to the dealer: ECM code =U0101 tcm code= none (failed to probe module) ABS code= U0101 ABS code= C0561 (issue with traction control system)- "service within 7 days" a quick search in automotive forums reveals several other people with almost the exact same issue, with no specific solutions.

The engine misses and has severe carbon buildup on the valves. The intake boot and intake manifold are covered in oil residue from the breather tube for the motor. The transmission started having issues at 100K. It hesitates, shutters, and fails to change gears while driving at highway speeds. The transmissions are a known issue and I dont understand how this is not a recall.

The contact owns a 2012 GMC Acadia. The contact stated that the transmission had been slipping in any gear from shifting out of park. The contact had to apply the emergency brake to prevent a potential failure if it may progress with no warning while changing gears. The vehicle has been inspected by an independent mechanic who suggested that the vehicle be taken to a dealer for inspection, diagnosis and to determine if there was a recall to service the transmission. A dealership has not been contacted yet. The manufacturer was contacted, had issued 38 tsb on power train and no recalls for power train/transmission yet. The vehicle was not repaired yet. The VIN was not available. The approximate failure mileage was 115,116.
