2013 GMC Acadia Problems

What owners report

Owners of the 2013 GMC Acadia most often describe electrical and air bag warnings — especially a persistent 'service air bag' message tied to wiring and connector concerns, and a 'service side detection' message from water in the blind-zone sensors. Transmission complaints, particularly hard shifting and torque converter trouble, and sudden engine stalls with multiple dash warnings also recur throughout the sampled complaints, usually from roughly 40,000 miles upward. Many of these reports come from vehicles well past warranty, so owners frequently describe paying out of pocket or being told nothing could be done.

   Air bags

   Service air bag light / air bag wiring problem

   • 22 complaints (16%)
   • median 95,000 mi at 6.8 yrs old (13 state mileage)
   • filed 2015–2023

   Owners describe a 'service air bag' message or air bag warning light that comes on intermittently and then stays on, whether parked, idling or driving. Several say the dealer diagnosed a faulty wiring harness or connector and cleaned or replaced it, sometimes more than once, yet the light returned. Some reports involve vehicles that had side air bag wiring work done under a recall and later showed the same warning again; owners say they were told the recall covered only one repair or that the vehicle was not covered. Reported from roughly 45,000 to 150,000 miles, with many clustered above 80,000 miles.

   What to check: Ask whether the side air bag wiring recall (14V118) was completed and whether the air bag light has come back since; scan for stored air bag codes and confirm the light goes out after the bulb check at start-up.

   “My car keeps popping up the 'service air bag' light. I have had it looked at several times. I was told that the connector needs to be cleaned. They have been cleaned but it keeps coming on. I see there was a recall for certain models but my car doesn't have any recalls currently. It will come on while sitting idle, driving, parker, doesn't matter. Help!”

   NHTSA complaint #11388886, filed 2021-01, 82,000 miles

   “I just purchased this vehicle. It shows a service air bag message. This was covered by a recall. Gm says the recall was completed on this vehicle. But GM also issued a sb indicating some recall repairs may have been faulty. I believe this was faulty in the case of my vehicle. A Gmc dealer looked at it and indicated that the work was not done properly. Gmc is refusing to correct the problem.”

   Electrical system

   Stalls and reduced-power warnings while driving

   • 18 complaints (13%)
   • median 69,945 mi at 6.0 yrs old (16 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2014–2025

   Complaints describe the vehicle stalling or losing power at various speeds, sometimes with the dash flashing 'service stability track', 'traction control off' or 'engine power reduced' messages. Some owners report the vehicle would not restart, or that the dash went dark and electrical functions dropped out. Dealers and mechanics variously replaced the throttle body, battery, alternator, fuel pump module or other parts, and in several cases the problem returned afterward. Spread widely from a few thousand to about 120,000 miles, with many reports between 40,000 and 100,000 miles.

   What to check: Have a shop check for stored codes and look at the throttle body, battery and charging system; ask the seller whether the vehicle has ever stalled or shown reduced-engine-power messages, and test a cold start plus a highway drive.

   “I purchased a 2013 Gmc Acadia from car max on february 16th of this year. After 3 weeks the battery was completely dead, but car max reimbursed the cost to replace. Fast forward to may 24th...as I try to leave from work the vehicle would not start. The dash displayed several messages: reduced engine power, stabilitrak off, and battery saver active. The vehicle was towed to tire kingdom and the diagnosis was a bad fuel pump/fuel pump module. The part was replaced and computer reset. …”

   NHTSA complaint #11109976, filed 2018-07, 44,507 miles

   “I was driving 50 MPH on a very busy city highway when I heard what sounded like a truck putting on air brakes but no trucks around me, I felt shuddering under my foot. Suddenly service charging system or something like that flashed on my dash and I lost power steering, acceleration, everything. I was able to pull hard on the wheel to get into the right lane from the center lane, there was no shoulder to pull off on. Brake was hard to depress, it felt like it was all the way to the floor. …”

   Electrical system

   Blind zone / side detection failure from water intrusion

   • 15 complaints (11%)
   • median 61,500 mi at 6.6 yrs old (14 state mileage)
   • filed 2016–2022

   Owners describe a 'service side detection system' message and blind-spot indicators that stop working or stay lit, which they attribute to water getting into the sensors behind the rear bumper. Some report the modules and a wiring harness being replaced one or more times, with the message returning after a short time. Several mention that a special coverage or bulletin repair applied only up to a certain mileage, and that dealers could not supply the revised harness or declined the repair once the vehicle was outside it. Mostly reported between about 45,000 and 120,000 miles, and several owners note the problem recurring after an earlier repair.

   What to check: Check that both mirror indicator lights and the side detection warning behave normally in wet weather, and ask whether the sensors or waterproof harness have been replaced and under what coverage.

   “The service side detection system has appeared in the dic due to water intrusion in the sensors. They were originally replaced per the tsb16-na-178 in april of 2019. The issue has since re-occurred 2/18/21 while driving, which jeopardizes my safety. I also understand that this may lead to additional electrical issues and may cause the vehicle to enter limp mode.”

   NHTSA complaint #11398958, filed 2021-03, 57,980 miles

   “Service side detection system problem bulletin no. 16-na-178 --- as described GM has a moisture problem getting in to the sensors-- how ever they refused to repair mine completely, in fact can not get a wiring harness to prevent this problem from re-occuring. Some song and dance about my ven is not included in this--how ever I had to have it repaired multable times?? Help? A car beside you and detection does not alert you- that is why you purchased it!”

   Transmission and drivetrain

   Hard shifting and torque converter problems

   • 23 complaints (17%)
   • median 103,000 mi at 6.3 yrs old (13 state mileage)
   • filed 2017–2026

   Owners report shuddering or harsh shifts, delayed upshifts to high engine speed, and in some cases the engine dying when coming to a stop. Complaints describe diagnosis of a failed torque converter, a broken drum and snap ring, or a transmission module that made the vehicle behave as though it were in park, with quotes in the thousands of dollars for a rebuild or replacement. Several owners say they were told there was no recall and that the repair would be at their own cost. Typically reported between about 45,000 and 120,000 miles, generally after the vehicle was out of warranty.

   2 related service bulletins

   What to check: Test drive from a stop through several upshifts and feel for shudder or hesitation, check the transmission fluid condition and service history, and ask whether the torque converter or transmission has been replaced.

   2 excerpts from owner complaints in NHTSA records

   “My 2013 Gmc Acadia car just started having shifting issues and turns out to be a transmission issue. The dealer states there is no recall and recommendation I replace the transmission which would cost about $4600. This is absolutely absurd. I just learned that Acadia's have transmission issues. And of course, nothing can be done because there is no recall on 2013 vehicles. Terrible business.”

   NHTSA complaint #11060743, filed 2018-01, 116,000 miles

   “My Acadia engine light came on when I put it in drive won't go anywhere. Acadia doors keep unlocking and locking was at my house in driveway. Engine light went off everything is fine. Took it to dealership and they said it's the transmission module making car think it's in park but can't fix it unless my engine light is on when I get it to them. Question from me is if it's thinking it's in park what if I'm driving 55 and it thinks it's in park I'll wreck. …”

   Steering

   Power steering whine and loss of assist

   Mentioned in 4 of 60 sampled complaints

   Owners describe a whining power steering pump and steering that becomes very heavy or briefly drops out, particularly at low speed, when stopping, or when the belt or pump gets wet. Some report the dealer identifying a leaking pump and recommending replacement, with the repair not covered once the vehicle was out of warranty. A few also mention the telescoping steering column moving or clicking on its own. Mostly reported between about 39,000 and 118,000 miles.

   1 related service bulletin

   What to check: Listen for pump whine at idle and while turning, check for fluid leaks around the pump and hoses, and test low-speed steering feel, ideally after the vehicle has been driven in rain.

   “My power steering pump is failing and my car is jolting forward when moving from a stopped position. The power steering is whining and has been for 6 months. The technician at my car dealership said it is a known issue, so why hasn't there been a recall on it? I travel highway a lot and fear for my safety and the safety of my children.”

   NHTSA complaint #11150140, filed 2018-11, 110,000 miles

   “At low speeds or stops the power steering get super tight like I don't have any power steering. Took it to the dealership and they said the pump is leaking and it should be replaced. I haven't even had it a year and it not covered. They even know its an issue. Seen a lot of other people have the same problem. Why is this not fixed ????”

   NHTSA complaint #11268620, filed 2019-10, 112,000 miles

Buying note. A pre-purchase scan for air bag, side detection and powertrain codes plus a thorough test drive covering stops, upshifts and low-speed steering will surface most of what owners describe here. Ask for records showing whether the air bag wiring recall and any side detection sensor work were completed, since repeat repairs are a common theme in these complaints.
