The start/stop accumulator endcap may have missing bolts.

What could happen. Missing bolts on the start-stop accumulator endcap could result in a transmission oil leak and may progress to a loss of propulsion, increasing the risk of a crash. A transmission fluid leak in the presence of an ignition source may increase the risk of fire.

Air bags: air bag/restraint control module (18V340000)

Filed May 24, 2018

What is wrong. General Motors LLC (GM) is recalling certain 2018 GMC Terrain vehicles. The sensing diagnostic module (SDM) that senses a crash and deploys the necessary air bags may not power down correctly when the vehicle is shut off, causing it to be inoperative when the vehicle is restarted.

What could happen. If the SDM becomes inoperative, it will not detect a crash or command the necessary air bag deployment, increasing the risk of injury in the event of a crash.

The fix. GM will notify owners, and dealers will reprogram the SDM with updated software, free of charge. The recall began June 29, 2018. Owners may contact GMC customer service at 1-800-462-8782. GM's number for this recall is 18179.

What is wrong. 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.

What could happen. 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.

The fix. GM will notify owners, and dealers will replace the right front intermediate drive shaft assembly, free of charge. The recall began August 25, 2017. Owners may contact GMC customer service at 1-800-462-8782 or Chevrolet customer service at 1-800-222-1020. GM's number for this recall is 17329.

Check that your car is on the list

Most campaigns cover only cars built in a certain date range or at a certain plant, so a 2018 GMC Terrain may or may not be included. The VIN is the only sure test. It is 17 characters, on the dashboard by the windshield and on the driver door jamb sticker. Look up your VIN.

How to confirm the repair is free

Call any authorized GMC dealer service desk and give them the VIN and the campaign number from the list above.
Ask them to confirm the campaign is open for your car. If it is, the parts and labor are covered.
If the dealer says the part is not in stock, ask for a written note with the date, and ask about a loaner if the notice says not to drive the car.
Keep the repair order. It shows the campaign number and proves the work was done.

If you already paid for a repair that a recall later covered, GMC may owe you a refund. Ask the dealer or GMC customer service about reimbursement, and keep your receipts.
