2012 Gmc Terrain Recalls, Issues & Maintenance

The 2012 Gmc Terrain carries 4 open NHTSA recalls — most recently covering ignition and power adjust. Owners report 4 recurring issue clusters, led by “Windshield wiper motor and linkage failure.” 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.

4 Open Recalls

ELECTRICAL SYSTEM:IGNITION

Campaign #16V502000 · May 7, 2016

Issue: General Motors LLC (GM) is recalling certain model year 2016-2017 Buick Verano and 2016 Chevrolet Malibu as the electronic park lock lever may allow the ignition key to be removed without the transmission being in PARK. Also, certain 2013 Buick Encore, 2011 Buick Regal, 2013-2014 Buick Verano, 2011-2016 Chevrolet Cruze, 2010-2013 Chevrolet Equinox 2013-2015 Chevrolet Malibu, and 2011-2013 GMC Terrain vehicles may have been serviced with similar defective replacement electronic park lock levers. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 114, "Theft Protection and Rollaway Prevention."

Risk: If the key is removed without the transmission in PARK, the vehicle may rollaway as occupants are exiting, increasing the risk of injury.

Fix: GM will notify owners, and dealers will inspect and if necessary replace the key cylinder lock housing, free of charge. The recall began on October 14, 2016. Owners may contact Chevrolet customer service at 1-800-222-1020, Buick 1-800-521-7300, and GMC 1-800-462-8782. GM's number for this recall is 50490 and 50491.

SEATS:FRONT ASSEMBLY:POWER ADJUST

Campaign #14V447000 · Jul 23, 2014

Issue: General Motors LLC (GM) is recalling certain model year 2011-2012 Buick LaCrosse, Regal and Chevrolet Camaro, as well as certain 2010-2012 Cadillac SRX, Chevrolet Equinox and GMC Terrain vehicles, equipped with power height adjustable driver and passenger seats. In the affected vehicles, the bolt that secures the driver's and passenger's power front seat height adjuster may fall out causing the seat to drop suddenly to the lowest vertical position.

Risk: If the driver's seat unexpectedly drops, the distraction and altered seat position may affect the drivers' control of the vehicle, increasing the risk of a crash.

Fix: GM will notify owners, and dealers will replace the height adjuster shoulder bolts, free of charge. The manufacturer distributed interim letters to owners on September 11, 2014. The recall began on December 26, 2014. Owners may contact GM customer service at 1-800-521-7300 (Buick), 1-800-458-8006 (Cadillac), 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC). GM's number for this recall is 14271.

TIRES:PRESSURE MONITORING AND REGULATING SYSTEMS

Campaign #11V511000 · Oct 19, 2011

Issue: GENERAL MOTORS (GM) IS RECALLING CERTAIN MODEL YEAR 2012 CHEVROLET EQUINOX AND GMC TERRAIN VEHICLES, MANUFACTURED FROM JULY 18, 2011, THROUGH SEPTEMBER 6, 2011, FOR FAILING TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NUMBER 138, "TIRE PRESSURE MONITORING SYSTEM" (TPMS). THE TIRE PRESSURE MONITORING SYSTEM IS DESIGNED TO ILLUMINATE THE TIRE PRESSURE WARNING LIGHT WHEN THE PRESSURE IN A TIRE IS 25% BELOW THE RECOMMENDED COLD TIRE PRESSURE. ON THESE VEHICLES, THE LIGHT WILL NOT ILLUMINATE UNTIL THE TIRE PRESSURE IS MORE THAN 25% BELOW THE RECOMMENDED COLD TIRE PRESSURE.

Risk: UNDERINFLATED TIRES CAN RESULT IN TIRE OVERLOADING AND OVERHEATING, WHICH COULD LEAD TO A BLOWOUT AND POSSIBLE CRASH. THE RESULTING CRASH COULD CAUSE SERIOUS INJURY. UNDERINFLATED TIRES CAN ALSO RESULT IN PREMATURE OR IRREGULAR WEAR, POOR HANDLING, AND POOR FUEL ECONOMY.

Fix: GM DEALERS WILL UPDATE THE BODY CONTROL MODULE FREE OF CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN ON OR ABOUT NOVEMBER 9, 2011. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438 AND GMC AT 1-866-996-9463.

EXTERIOR LIGHTING:HEADLIGHTS

Campaign #22V137000 · Aug 3, 2022

Issue: General Motors, LLC (GM) is recalling certain 2010-2017 GMC Terrain vehicles. A reflection caused by the headlight housings may illuminate areas above the vehicle and outside of the driver's view with excessively bright light. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."

Risk: The bright reflection may cause a glare for other drivers, reducing their visibility and increasing the risk of a crash.

Fix: Dealers will install headlamp appliques, free of charge. Owner notification letters were mailed September 8, 2022. Owners may contact GMC customer service at 1-800-462-8782. GM's number for this recall is N222363740.

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

~$85–$115

DIY

~$25–$55

Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.

~$85

Shop

~$60

DIY

Free

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

~$85

Shop

~$60

DIY

Free

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
