Defect investigations
Front Wiper Transmission Inoperative
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). the federal safety agency reserves the right to take additional action if warranted by future circumstances.The ODI complaints cited above can be viewed at under the following ODI identification numbers in a separate attachment.

Windshield Wiper Transmission Failure
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.

Most recent owner complaints, unedited.
Tailgate lifts by itself
I am submitting this complaint regarding the engine timing chain failure in my 2015 GMC Terrain because I believe it presents a serious safety hazard. Before the failure, the vehicle began experiencing intermittent symptoms, including engine jerking, shaking, rough operation, abnormal engine noises, and an intermittent check engine light. While driving on the highway, the engine timing chain failed, causing the vehicle to suddenly lose power. I was traveling at highway speed and had to safely maneuver the vehicle out of traffic. The unexpected loss of power placed me and other motorists at risk of a collision because I could no longer safely maintain the flow of traffic. The vehicle was towed to an independent repair facility, where the engine was diagnosed with a timing chain failure. I was informed that the engine had sustained significant damage and required replacement. After purchasing and installing a replacement engine, that engine also began exhibiting timing chain-related symptoms immediately after installation, including abnormal rattling noises and unstable engine operation, resulting in additional repairs and the vehicle remaining unsafe to drive. I am concerned that timing chain failures in this model can occur without sufficient warning and can cause a sudden loss of engine power while the vehicle is being driven. A sudden engine failure at highway speeds creates a significant risk of a crash, injury, or death. I am requesting that this issue be investigated to determine whether it represents a safety-related defect affecting other 2015 GMC Terrain vehicles.

See attached document for complaint.
The contact owns a 2015 GMC Terrain. The contact stated that while driving approximately 40 MPH, there was an abnormal rattling sound coming from the engine compartment. The vehicle was taken to the residence. The contact stated that when the vehicle was started the following day, the rattling sound from the engine compartment returned. The vehicle was taken to a dealer on several occasions, and it was diagnosed and determined that the engine was low on oil and was consuming 2 quarts of engine oil every 2-3 weeks. The contact stated that the oil level was topped off. The manufacturer was notified of the failure. The failure mileage was approximately 94,000.
Oil consumption, causing high pressure furl pump to clog. It also causes catalytic converter to clog. No warning of oil loss. Causing stalling out while driving. Caused the engine to seize. New engine replaced and still same problem s
2015 gmc terrain sle awd. Suv was taking in for oil change found excessive rust on frame under all four doors. On both sides rust and holes near the front of both rear wheels. I believe its called the "rocker" I'm unsure. I bought the car at a little over 71,000 miles in 2022-2023 now just getting to 94,000 in February 2026. If there was rust which there probably was the car should have not been sold if the rust was enough to cause problem later on. I may need to go purchase a new car while still owe some money in the car loan. Rust and hole in the rear control arm. The amount to replace and repair all the parts with labor exceeds current value.
The radio dead out randomly. Which means the back up camera is non working. I wasn’t able to see a stump and hit it. Doesn’t seem safe. Like what would has happened if it was a person instead and they like the stump was in my blind spot while backing up. I feel like this is a safety issue. I have looked it up online and found out this is a common issue with these vehicles.
