2018 Gmc Acadia Recalls, Issues & Maintenance

The 2018 Gmc Acadia carries 2 open NHTSA recalls — most recently covering fuel pump and driveshaft. Owners report 5 recurring issue clusters, led by “Shift to Park warning with vehicle in park.” GMC trucks and SUVs use the GM Oil Life System (OLS) — the same algorithm as Chevrolet. Because GMC's lineup is exclusively trucks and SUVs, severe-service intervals apply to most owners (towing, hauling, off-roading). The schedule below surfaces the items most relevant to GMC's truck-focused buyer.

Issue: General Motors LLC (GM) is recalling certain 2018 Chevrolet Equinox and GMC Terrain vehicles and 2017-2018 GMC Acadia vehicles. The right front intermediate driveshaft may fracture and separate while driving.

Risk: If the front right intermediate drive shaft assembly separates while driving, the vehicle will lose propulsion, increasing the risk of a crash. If the assembly separates while parked on a grade, without the park brake engaged, the vehicle may move unintentionally, increasing the risk of a vehicle roll-away.

Every 7,500 mi

Change oil when OLS reaches 0% or every 12 months. dexos1-approved synthetic required on Sierra 1500 5.3L/6.2L; dexos2 specified on Duramax diesel.

Estimated cost — typical U.S. ranges

Dealer

~$120–$160

Shop

~$60

DIY

Free

Often free at the shop where you bought the tires — worth asking before paying.

Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.

Estimated cost — typical U.S. ranges

Dealer

~$180–$200
