2012 GMC Terrain

On June 1, 2020, the Office of Defects Investigations (ODI) opened PE20-009 to investigate instances of a momentary increase in steering effort after the vehicle is driven in a straight line for a period of time due to an issue with the steering gear in model year (MY) 2010 through 2012 Chevrolet Equinox and GMC Terrain SUVs.If the electric power steering system fails to operate as intended, the driver will experience momentary increased effort when attempting to turn the steering wheel from the straight-ahead position. For this condition to occur, the driver would need to have traveled in a straight line at a sustained high speed, without turning the steering wheel, for approximately 30 minutes or longer. The steering gear contains a servo unit that includes a worm gear with a worm and a worm wheel. General Motors (GM) stated that the primary root cause of the increased steering effort is the supplier's inconsistent application of grease in the interface between the worm and the worm wheel. The grease may have been applied in a location on the worm wheel that didn't interface with the worm, depriving the worm gear of proper lubrication.On November 1, 2014, GM issued Special Coverage 14232 to address the power steering stick-slip issue in MY 2010-2014 Chevrolet Equinox and GMC Terrain; MY 2011-2014 Chevrolet Cruze and Volt; MY 2012-2014 Buick Verano; and MY 2013-2014 Chevrolet Malibu vehicles. GM notified consumers via mail.The Special Coverage repair includes the replacement of the steering gear with an improved internal worm gear greasing process for MY 2010-2012 vehicles. For the MY 2013-2014 vehicles, the Special Coverage repair includes a reprogramming of the steering gear control module. The new software has an anti-stick feature which senses and reduces the friction between the worm and worm wheel by oscillating the worm gear. GM stated that the difference in remedy is due to the inability of the MY 2010-2012 steering gear control module to accept the new software.The remedy implemented in GM Special Coverage 14232 appears to be sufficient in addressing the safety-related concerns of this issue. Considering the low complaint and warranty rates of steering rack replacement as well as the field exposure time for the subject vehicles, the potential safety consequences of this issue are very low. To date, there have been no reported crashes, injuries, or fatalities related to this issue. ODI has not identified a safety defect or defect-related failure trend in the subject vehicles. In view of the Special Coverage, low rate of failure, and low potential hazard to drivers, this Preliminary Evaluation is closed. The agency reserves the right to take additional action if warranted by new circumstances.Review the ODI reports cited above at nhtsa.gov under the following identification numbers:11424633,11421725,11229647,11101375,10919921,10689932,10671557,10664687,10663350, 10593429,10592065,10585476,10585365,10576237,10575693,10532766,10490295,10434128, 10417845,10412535,10403168,10395532,10395171,10391948,10384211,10375515,10366297, 10360999,10360599,10345626,10319530,10305569,10304769,10299745

On December 13, 2019, the Office of Defects Investigation (ODI) upgraded RQ18-002 to an Engineering Analysis (EA19-005) to further assess the MY2010-2016 Chevrolet Equinox and GMC Terrain windshield wiper failures. Due to a prior recall, 16V-582, addressing this issue in the MY2013 subject vehicles, MY2013 was not included in the analysis. To date, ODI had received 998 complaints with allegations of the front windshield wiper failing in adverse whether conditions, while the vehicle was in motion.General Motors (GM) initiated Safety Recall 16V-582 on August 3, 2016 to address windshield wiper failure in the Model Year (MY) 2013 Chevrolet Equinox and GMC Terrain. Failures were attributed to water and debris intruding into the windshield wiper assembly ball joints, leading to excessive wear and eventual detachment of the affected ball joint resulting in loss of windshield wiper function. ODI?s review focused on 2010-2012 and 2014-2016 Equinox and Terrain vehicles. Owners were reporting a high rate of failures of the windshield wiper system. These failures were the same as that addressed by recall 16V-582. ODI's review of data supplied by GM as well as its own confirmed a high failure rate in model years 2014 and 2015. On March 17, 2022, GM filed a defect information report recalling all MY2014-2015 Chevrolet Equinox and GMC Terrain vehicles to remedy the potential failure of the front windshield wiper transmission assembly.General Motors is also conducting a special coverage program, N192266181, for MY2010-2012 and MY2016-2017 Chevrolet Equinox and GMC Terrain vehicles. The special coverage is for a period of 15 years or 200,000 miles, whichever comes first.Both the recall, 22V-165, and the special coverage program, N192266181, address windshield wiper system failures on the subject vehicles. The dealership will inspect the front wiper assembly for ball joint wear. Depending on the degree of wear, the wiper links will be replaced, and a water shield installed or the entire module will be replaced.In view of the recall and special coverage, ODI is closing this Engineering Analysis (EA). NHTSA reserves the right to take additional action if warranted by future circumstances.The ODI complaints cited above can be viewed at www.nhtsa.gov under the following ODI identification numbers in a separate attachment.

On November 2, 2018, the Office of Defects Investigation (ODI) opened a Recall Query (RQ18-002) to assess the scope of Recall 16V-582.General Motors (GM) initiated Safety Recall 16V-582 on August 3, 2016 to address windshield wiper failure in the Model Year (MY) 2013 Chevrolet Equinox and GMC Terrain. Failures were attributed to water and debris intrusion into the windshield wiper assembly ball joints, leading to excessive wear and eventual detachment of the affected ball joint with an attendant loss of windshield wiper function. The recall remedy addressed these conditions with the installation of an improved windshield wiper motor/transmission assembly and the relocation of a drain hole on the Air Inlet Panel at the base of the windshield.RQ18-002 was opened to assess windshield wiper failure rates in the MY 2010-2012 and MY 2014 - 2016 Equinox and Terrain (subject vehicles).During the course of the investigation, ODI received additional consumer complaint traffic bringing its total to 602 concerning the alleged defect in the subject vehicles. In their December 20, 2018 response to ODI's Information Request (IR) Letter, GM reported 1,303 complaints related to the alleged defect in the subject vehicles. Together, these bodies of data correspond to 1,905 unique Vehicle Identification Numbers (VIN).GM stated the recalled vehicles exhibited double the warranty rate and five times the complaint rate of the subject vehicles and that continuing complaint traffic concerning the alleged defect in the subject vehicles stemmed from publicity surrounding Recall 16V-582.ODI's review of GM's data confirms the stated difference in failure rates between the recalled and subject vehicles. However, ODI believes that the subject vehicle failure rates are nevertheless elevated and that publicity alone cannot account for the continued consumer complaint traffic concerning the alleged defect in the subject vehicles. ODI is upgrading to RQ18-002 to an Engineering Analysis to compare subject vehicle failure rates and engineering practices to those in peer vehicles.The 602 ODI complaints cited can be viewed in a separate attachment.

My car has started stalling and dying when i slow down, take off or when idling. No power when accelerated, and the smell of exhaust comes into my car. I was making a turn from a red light and my car spit, sputtered, and died right in the middle of the busy intersection. I was almost hit from the rear and another car had to go into on coming traffic to avoid T boning me. I took it to 2 different places to get a diagnosis reading and both places said it was a catalyst problem, and I was told that there was a recall about that because of engine oil clogging it up. My car has been using more oil than usual here lately and im guessing thats why. Now, im afraid to drive anywhere because I don't feel like it safe and the fact that my car doesn't run good enough to drive. I was told by more than 1 person that knows mechanics, that its a issue with the catalyst and that it had a recall on it but I never received one. This is a very concerning safety issue, and one that needs immediate attention before someone gets badly hurt (or worse) because of a bad car part . My car is literally just a lawn ornament now until I can get this issue resolved. I need my car to make a living and support my family. PLEASE, get the recall letters out and get this fixed before someone loses a life.

1. The engine suddenly lost power while driving during evening rush hour and the vehicle would no longer accelerate. 2. Because the vehicle could not maintain speed, I was unable to keep up with traffic, creating a serious safety hazard that could have resulted in a major accident. 3. The vehicle has been inspected by an independent service center for diagnosis. 4. During the incident, the “Engine Power Reduced” warning indicator illuminated just before the loss of power occurred. 5. As the vehicle slowed and came to a complete stop at an intersection, it remained unresponsive. When the traffic light turned green, the vehicle would not accelerate at all.

GMC Consumer Relations Subject: Structural Undercarriage Safety Defect – 2012 GMC Terrain SLE Vehicle Information: Year/Make/Model: 2012 GMC Terrain SLE VIN: [XXX] Mileage at Purchase: 148,305 Date of Purchase: [XXX] Location: Rochester, New York I am filing a complaint regarding a severe undercarriage safety defect in my 2012 GMC Terrain SLE. The rear undercarriage of this vehicle shows heavy structural corrosion on suspension brackets and mounts. The condition produces clanging noises during normal driving, and an independent licensed mechanic has refused to work on the vehicle because the suspension integrity is unsafe. When I returned the vehicle to the dealer, I observed additional brackets being attached under the rear subframe area, suggesting reinforcement of compromised structural points. This confirms that the corrosion directly affects suspension geometry, alignment, and stability. This corrosion is not cosmetic. It is advanced structural deterioration affecting the mounting points for trailing arms and lateral links. These components are critical to safe turning, stability, and control. The corrosion compromises the ability of the suspension to keep the wheels aligned, creating serious risks of loss of control or wheel separation. What makes this more alarming is that the vehicle passed a New York State safety inspection on 07/13/2025, yet within days a mechanic refused to perform unrelated service because of the undercarriage condition. This raises questions not only about inspection validity, but also about the underlying durability and corrosion.
