We purchased a 2023 GMC Acadia AT4 new in October 2023. There is currently a little over 19,000 miles on the AT4. As of today November 13, 2024 the SUV has been to Blaise Alexanders, for at 3 times with same issues. Between the speeds of 50-65 there is a shudder, which in August 2024, the Chevy garage changed the fluid However, You can now feel this at any speed through out a trip. The SUV was return to the shop for increasingly worse shudder between 50-65 and a new issue of "hunting" between 25-35. There are times that the SUV does not want to propel forward (like the AT4 cannot get out of its own way) Also, when making a sharp right turn followed by an immediate left turn, onto uneven surface, the AT4 acts as though it is confused as to what gear it should be. The garage was then notified that I know have whining sound. At one point the garage had the AT4 for a week, the general manage drove it, did not feel anything. I then returned, took him for drive and he felt it. Left the car for him to take one of the "transmission" repair individuals out on a drive with the scan tool hooked up. Results of that test drive---"the car did it once, slightly but it was not picked up on the scan tool." Troy, from the service desk informed us they called GM to have their traveling engineer come look at the AT4 in a few day. GM's representative stop at the garage, DID NOT look at the car or speak to us, but has Troy tell us to keep driving the car. We are now in November and unfortunately, I got a little behind on bugging them due to the loss of my brother, father and step -father. But then again they have made no attempt at resolving this issue. This is frustrating. We are asking for any assistance that you can provide. I find it hard to believe that we are the only individuals that are experiencing these issues. I love my car. Why did they change the fluid if nothing was wrong the first time?? It has progressively been getting worse and winter is coming......

What owners say
Whining noise from rear axle when 4x4 engaged.
Looses power while driving. Cannot jump the battery it needs to be recharged every time. Power steering stops working while driving( low rpm and when stopped) dangerous for merging or lane changes. Engine shudders when trying to accelerate. TCM/ ECM replaced 2020. Problem still persists. Whining noise upon start of the vehicle. Auto start will not work. traction control light, check engine airbag and
Loss of power steering: bought NEW late 2017: In 1st month a whining noise was present while turning the steering wheel in any direction (driving or in park) even when slightly turning the wheel. At the time, didn't seem to effect anything. Difficulty started around 80k miles & continued to get worse as time went on. Each time varies on type of turn, speed of turn, how long the car has been in use. On average: it starts (& continues to get worse) after the first 10/15 minutes of driving. Loss of steering comes & goes (not only happening while turning) for at least 4 -15sec. In the last year (mid 2021 - 2022) went to mechanic -couldn't find an issue. Husband checks fluid levels monthly (no changes/no leaks are visible ). As of May 2022 (130k miles) turning into parking lots/spots/driveways/etc I have NO power steering, my husband is barley able to turn the wheel during these events. Its unsafe to drive. Doesn't seem to be as bad if speed is 20mph or faster. Shudder issue (maybe @60kmiles): *We had this issue w/our 2012 Acadia too. Multiple GMC Certified mechanics have been used to correct this. Only one mechanic was able to witness the shuddering. All things tried have failed to correct it. First started happening between 35 - 55mph (now its at any speed: 10 - 80mph), speeding up used to make it shudder less, turning traction control off USE to make it shudder less. Plenty of forums abt this issue including all things tried & failed. No resolution. Shudder causes car to not accelerate at times. RPM jumps high & bounces around. AC would stop working (started @20k miles) it makes an air releasing noise when AC is in use. *2012 Acadia did this too. Adding Freon helps for limited time. No leaks. Mechanics "CND", its still not fixed. "Tighten fuel cap" warning comes on randomly. When checked, its tight. Automatic start fails randomly, since day 1. "Ck Engine" light comes on & off randomly. Main issue was the shuddering *Reporting date used for loss of power steering.
2007 gmc acadia, has had problem steering issues since purchased, loud whining noise from power steering, steering was fine for a along while even with the noise but now power steering, issues in electrical system, windows not always rolling down. Blinkers work but no sound and radio doesn't play. Makemodelyear gmc acadia 2007
45,000 miles. 2014 acadia slt2 awd. Power steering failure. Fluid driven power steering is failing, loud whine noise from hydraulic fluid pump. Fluid is full. Steering is very hard to turn, no power assist especially at slower speeds or at a stop. Slightly better if raising engine speed above 2500 rpms
When I slow down to make a turn regardless if I turn right or left it's very hard to steer. Sometimes it makes a whining noise that it's never made before until now and as of this past weekend any time I try to turn its extremely hard. I almost got hit several times just trying to get my car home from a friend's house. My husband checked the power steering fluid and it's full.
2016 gmc acadia slt-1, 58,000 miles. Total loss of power steering backing out of a parking space with no prior symptoms. The car would barely turn at low speeds and made a loud howling noise when wheel was turned. I took the vehicle to the dealer and they tell me I need the power steering pump, rack and pinion and all new hoses. No prior wrecks or issues. This is ridiculous to be hit with a $4100 bill with no explanation of why this could happen.
Steering wheel making a whining/rubbing noise. Fluid leaking under the car. Took to the dealer and was found to have tack and pinion is bad spraying out power steering fluid everywhere. Was told that the steering will lose power and become either hard to turn or not turn at all causing danger to ourselves and others. This is a known issue that has not been recalled by gm.

Power train: automatic transmission
- What is wrong
- General Motors LLC (GM) is recalling certain model year 2014 Buick Regal, LaCrosse, Verano, and Enclave, and Chevrolet Impala, Malibu, Cruze, and Traverse, and GMC Acadia vehicles equipped with automatic transmissions. In the affected vehicles, the transmission shift cable adjuster may disengage from the transmission shift lever. As such, these vehicles do not conform to Federal Motor Vehicle Safety Standard (FMVSS) number 102, "Transmission Shift Lever Sequence, Starter Interlock, and Transmission Braking Effect." They also fail to conform to FMVSS number 114, "Theft Protection and Rollaway Prevention."
- Risk
- If a vehicle's shift cable disengages from the transmission shift lever, a driver may be unable to shift gear positions and the indicated shift position may not represent the gear position the vehicle is in. Should a disengagement occur while the vehicle is being driven, when the driver goes to stop and park the vehicle, the driver may be able to shift the lever to the "PARK" position, but the vehicle transmission may not be in the "PARK" gear position. If the vehicle is not in the "PARK" position there is a risk the vehicle will roll away as the driver and other occupants exit the vehicle or anytime thereafter. A vehicle rollaway increases the risk of injury to exiting occupants and bystanders.
- Remedy
- General Motors will notify owners, and dealers will inspect and replace any affected transmission shift cable adjusters, free of charge. The recall began on April 10, 2014. Chevrolet owners may contact General Motors at 1‑800‑222‑1020, Buick owners at 1‑800‑521‑7300, and GMC owners at 1‑800‑462‑8782. General Motors' number associated with this recall is 14048.
