2015 GMC Acadia Problems

What owners report

Owners of the 2015 GMC Acadia most often describe power steering that becomes stiff or quits at low speeds, and air bag warning lights that come on intermittently, often alongside questions about open recalls and parts availability. Another recurring theme is water getting into door and liftgate wiring and shorting out audio and lighting circuits, with a smaller group describing rough or shuddering transmission shifting. Reported mileage varies widely: steering and electrical complaints cluster in the 40,000 to 90,000 mile range, while air bag reports often arrive well past 100,000 miles.

1. 1
   Steering

   Power steering stiff or failing at low speed

   • 27 complaints (11%)
   • median 56,000 mi at 4.5 yrs old (24 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $1,000 (median of 8 quotes)
   • filed 2015–2024

   Owners describe the steering wheel becoming very hard to turn, usually while parking, making a slow turn, or pulling out of a space, and in some cases the assist drops out completely. Many report grinding, whining or squealing noises beforehand. Complaints say shops diagnosed a leaking or failed power steering pump, and sometimes the pressure hose or rack, with repairs commonly quoted around $1,000 or more. Several owners note the assist returned after restarting the vehicle and that dealers or the manufacturer declined assistance once the vehicle was out of warranty. Mostly reported between roughly 30,000 and 70,000 miles, with several owners describing the problem getting worse over a period of months.

   What to check: During a test drive, turn the wheel lock to lock at idle in a parking lot and listen for whining or groaning, then check the power steering fluid level and color. A service bulletin describes flushing and bleeding the power steering system to address noise or fluid leaks in extremely low temperatures.

   2 excerpts from owner complaints in NHTSA records

   “Vehicle started making grinding / squealing noises while driving when I turned. Steering was very tight and hard to turn wheel. Brought vehicle into shop and power steering pump was leaking. $1,100 dollars later my vehicle was fixed and I was told that I could have lost my steering all together if the power steering fluid was depleted anymore.”

   NHTSA complaint #11253063, filed 2019-09, 60,000 miles

   “Power steering reverts to manual. This occurs generally at low speeds when turning in any direction. This could be extremely dangerous if the problem occurred at highway speed. The problem feels like the steering is locked. I have read numerous complaints about this problem. Hopefully we will not wait until someone gets killed before Gmc issues a recall.”

   Air bags

   Air bag warning light on; recall parts delays

   • 102 complaints (42%)
   • median 91,841 mi at 6.2 yrs old (16 state mileage)
   • 4 mention a crash, fire or injury
   • filed 2016–2026

   Complaints describe the service air bag light coming on and going off for days before staying on, with no crash involved, and in some cases a seat sensor is diagnosed as the cause. Several owners mention receiving notice of a driver-side inflator recall but being told the remedy parts were not yet available, so the light stayed on. A few report air bag material deploying inside the driver's seat or dashboard trim breaking loose without an impact. Quoted repair costs for the warning light have been reported around $1,500. Reports span a wide mileage range, with many filed past 90,000 miles and several between 40,000 and 70,000 miles.

   What to check: Ask the seller for proof that the open air bag recalls were completed and have a dealer check the campaign numbers against the VIN. Watch the air bag light through a full drive cycle, including with a passenger in the front seat, since intermittent lights are commonly described.

   2 excerpts from owner complaints in NHTSA records

   “Within the last week, my service air bag light came on and then would go off, either while driving or sitting. I could be driving down the road, the light would come on, stay on for a minute, go off for a minute and come back on. It did this for several days. Now the service air bag light stays on all of the time. The vehicle has not been in a crash.”

   NHTSA complaint #11363786, filed 2020-10, 88,683 miles

   “Service air bag light has been coming on and off for a few months now. It doesn't consistently stay on. It comes on sometimes when I have my purse in the passenger seat. The car can be moving or idle. I've seen other complaints regarding this same subject. I got a diagnostic test at the dealer and they said it would be $1566.00 to repair it.”

   Electrical system

   Water intrusion shorts door wiring and audio

   Mentioned in 7 of 60 sampled complaints

   Owners report water collecting near the door hinges or inside the rear doors and reaching the wiring and amplifiers, after which the radio, turn signal clicks, seat belt chimes and backup sensor sounds stop working. Others describe the rear hatch opening on its own at random, which some attribute to water in the liftgate switch, followed by battery drain and headlight trouble. Complaints say repairs run around $1,000 and that the problem returns because the drainage path is unchanged. Typically reported between about 40,000 and 105,000 miles, often noticed after several days of rain.

   1 related service bulletin

   What to check: After rain or a wash, check the carpets, door sills and spare tire well for dampness, and test the radio, chimes and turn signals. Ask whether door or liftgate harnesses have already been replaced.

   2 excerpts from owner complaints in NHTSA records

   “The issue started with my back hatch opening on its own at random times. Found out this was caused by water entering the lift switch. That problem lead to the battery eventually going bad and then the headlights being blown due the bad battery. Not sure how water got in the back hatch ruining the sensor but this is costing me about $1000 to fix.”

   NHTSA complaint #11386658, filed 2021-01, 63,000 miles

   “It appears that the electrical system to the car radio has shorted out. It effects the sound to the blinker as well as to the radio. I am very concerned that it may have other electrical problems. Is this covered under any kind of recall. I have heard that the whole dash could be effected and my car just stop running. The car was not running when this happened. I open the passenger side front door and it made a loud noise which sounded like it was shorting out. The vehicle runs but am very leary about taking it on a long trip. …”

   Other or unknown

   Air conditioning blows warm or loses charge

   Mentioned in 5 of 60 sampled complaints

   Owners report the air conditioning blowing warm air, often within the first few years of ownership, with shops diagnosing a leaking compressor hose, a failed evaporator that requires removing the dashboard, or a system needing a recharge every year. Some say the concern was raised at the dealer early but could not be duplicated at the time. Repairs are described as costing roughly $1,000 to $1,500. Reported from under 20,000 miles up to about 42,000 miles, and most noticeable in hot summer weather.

   1 related service bulletin

   What to check: Run the A/C on maximum for several minutes and confirm cold air from the front and rear vents, and look for oily residue around A/C lines and the compressor. Ask whether the system has been recharged or any A/C components replaced.

   2 excerpts from owner complaints in NHTSA records

   “I just purchased this car three months ago, the A/C is no longer blowing cold air. The air blows but not cold and the heat works just fine. From what I've read online, this appears to be a common issue on this make and model. Please address this..”

   NHTSA complaint #11363946, filed 2020-10, 16,000 miles

   “This could have been resolved under warranty, because at the time I had less than 36,000 miles but the car was at 38 months when the air conditioner went out and blowing warm air when the summer time temps were in the 90s. I took it to my Gmc service dept and was told the evaporator needed to be replaced. The problem was it is a labor intensive repair that requires removal of the dashboard to get to the evaporator. $1500 later I now have cool air in the car I paid $40,000 for. …”

   Transmission and drivetrain

   Rough or shuddering transmission shifting

   • 25 complaints (10%)
   • median 49,000 mi at 3.2 yrs old (13 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2015–2026

   Owners describe the transmission bucking or shuddering when slowing to a stop or accelerating out of a turn, with delayed or abrupt downshifts and sluggish acceleration. Some reports say a solenoid or control module was replaced or reprogrammed and the behavior returned later, while others say a dealer replaced the transmission. Complaints also mention a dealer describing a brief throttle delay as normal. Reports range from very low mileage on nearly new vehicles up to roughly 90,000 miles.

   2 related service bulletins

   What to check: Drive slowly in a parking lot and again from a stop, feeling for shudder or hesitation on downshifts. Ask whether any transmission reprogramming, solenoid or control module work has been done, and keep records if the behavior returns.

   2 excerpts from owner complaints in NHTSA records

   “After picking up our new truck we noticed that the vehicle's engine was short jumping at low speeds, especially when in traffic - at first when this occurs you have to almost ask yourself did I hit the gas pedal instead of the brakes. After only a couple weeks of ownership we dropped off our new vehicle to be repaired. …”

   NHTSA complaint #10759537, filed 2015-08, 1,622 miles

   “Bad shifting in transmission when you slow down or come to a stop and turn right and accelerate at the same time. This happens on the 2014 and 2015 models, tranmission will stutter and abruptly shift into a lower gear. On the Acadia forums it is documented by other owners as well (approx 30-50 other owners). The transmission needs a reprogram to account for this issue. Gm appears to not be doing anything about this common issue.”

   NHTSA complaint #10723577, filed 2015-06, 1,000 miles

Buying note. Before buying, confirm the open air bag recalls were completed and drive slowly in a parking lot to judge whether the steering assist feels normal. Check door sills and the cargo area for water damage and test the A/C thoroughly, since those repairs are frequently described and can be costly.
