NHTSA Campaign: 23V339000 SAFETY RECALL
668.2K Vehicles Affected
Recall Date: May 11, 2023
Safety Issue:

General Motors, LLC (GM) is recalling certain 2020-2023 Chevrolet Equinox and GMC Terrain vehicles. The four rear-seat lower child seat LATCH anchorage bars may have excessive powder coating, which could prevent a child seat from being installed with the anchorage bars. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 225, "Child Restraint Anchorage Systems."

Potential Risk:
The inability to install a child seat with the LATCH anchorage bars could result in an unsecured child seat, increasing the risk of injury in a crash.
FREE Recall Solution:
Owners are advised to install child seats using the vehicle's rear seat belts until the remedy is complete. Dealers will inspect the latch anchorage bars, and remove and replace the finish, as necessary, free of charge. Owner notification letters were mailed June 2, 2023. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is N232403240.

SEAT BELTS

Potential Consequences:

Driver seat belt exhibits signs of fraying in area of belt hidden from view when not in use. When extended, hair-like fibers extend out, primarily from the car-forward side of the belt in the area coming out of the B-pillar and from behind the trim. It is available for inspection. Concerned that this may continue to degrade the integrity of the seat belt over time. There could be something sharp in the retractor, or flash on a piece of plastic trim hidden from view causing this. My understanding is that if there is a small nick on the edge of a safety belt it can tear across, and concerned that this condition could lead to a similar outcome over time and if the vehicle were involved in an accident. Upon taking to local dealership, was advised that this is a normal condition and not a concern. Advisor said technician told him that it is not fraying, it is a normal condition that can be exhibited by the belt fibers, especially towards the edges. They said the central portion of the belt is not exhibiting a similar condition and therefore not a concern. The fibers seem to have grown in quantity since vehicle purchase. I first recall seeing them during the pandemic, although became more concerned over time and finally took in prior to warranty expiration for review.

ENGINE

Potential Consequences:

I just purchased this vehicle about 2 weeks ago, and was driving through the fog/cold weather and my check engine light came on. Went to O'Reillys and had them check the code. Came up as P0299 (My car was telling me that the engine power was decreased) I had a loss of power I could feel while driving as well. The code said turbo under boost. After I got back into town and the weather was warmer and no fog was present, the turbo started working again. I brought my vehicle into the dealer where I bought it from and they took it to their mechanic and supposedly performed an "update". I will see if I continue to have the same issue in cold weather as I live in Idaho and go to the mountains often.

SERVICE BRAKES

Potential Consequences:

My service brake assist light came on and then within seconds my vehicle then said engine power has been lowered and my vehicle pretty much shut down no steering no brakes couldn't do anything. Took it into the repair shop and my vacuum pump has shattered and now damaged my camshaft. I am aware there's been many other vehicles recalled with GM's vacuum pumps and I'm not sure why my year and model has not been included when it's doing the same thing and not to mention I have seen countless other cases of people saying same things happen to them with their GMC terrains.

POWER TRAIN

Potential Consequences:

In January 2022, I purchased a 2020 GMC Terrain from a local GMC certified dealership along with an extended warranty. In July 2022, I started to experience intermittent acceleration issues. The issue only presented itself upon vehicle startup and was very sporadic. Upon startup, the vehicle was very slow to accelerate even with the gas pedal depressed to the floor. The vehicle would move at an extremely slow rate of speed for approximately 10 to 15 seconds before the vehicle would engage and actually start moving forward at the expected rate of speed. This would happen 4 to 5 consecutive times before things seemed to "warm up" and run smoothly. It proved to be dangerous at intersections if making a left hand turn into oncoming traffic or during heavy traffic times. From the beginning of July to Aug 9th, this has happened on 5 separate occasions. The story is the same, I start the car after it has been sitting for a bit (it's been from several hours to several days) and the issue will present itself without warning. There are no fault or error codes. I've taken the vehicle to my mechanic as well as the dealership where I purchased the car and both have run diagnostics on the vehicle with no luck. My mechanic did drive the car and he experienced the issue first hand but he could not figure out what was wrong. In the event other Terrain owners are experiencing this same sporadic acceleration issue with no fault or diagnostic codes, I wanted to make sure we documented our issue. I did not record the dates of the first few instances but the last two have been July 24th and August 9th.

It also can cause a delay when pulling out into heavy traffic. There is currently no way to temporarily or permanently defeat the system on this GM model according to GM service department. Though I am sure it is operating as designed for certain owner driving styles and traffic conditions this can be a serious hazard. Car makers should be required to either disable the feature permanently by owner request or have a method for the owner to bypass the system. With less than 250 miles I have experienced 2 incidents of almost hitting the car in front of me from a stop and 1 of almost being hit pulling into heavy traffic from a stop. I see many other similar complaints and hope this can be addressed before someone is hurt or worse due to it.

Defect Description:

FUEL/PROPULSION SYSTEM

Potential Consequences:

I had been fishing at the lake and went to leave and when I got in my car I put it in reverse and backed up then put in drive to pull forward, only I pushed the throttle all the way to the floor and the vehicle was completely unresponsive. I put it back in reverse and backed up a little more then put back in drive and same thing happened. I then put it in neutral and have it gas and with the pedal to the floor it barely revved the engine at all. I put it back in drive and floored it again and started turning the when from side to side still nothing. I put it in park then back in drive and with the gas pedal to the floor it barely started to creep forward. It continued to creep for about 40ft then all of a sudden the throttle worked and vehicle jerked forward. 2 days later I was driving in town with my daughter in the car and slowed down before turning up a steep hill and the vehicle did the same thing. Gas pedal to the floor and wouldn't accelerate. Only this time I almost got rear ended. I have contacted the dealer and told them I need a loaner while my vehicle is fixed and their response was "I don't know what to tell you we don't have any". I called GM and they said they would contact the dealer and see if they just don't have any loaners available or of they don't offer them and said they would call me back. The end of the next day I still haven't heard from them so I reach out to them again this time being told "an owning advisor has already handled your claim, sorry you haven't been updated yet". I don't need updates, I need a safe vehicle for me and my kids! My car has only 57XXX miles plus I bought a 100,000 extended warranty. Please hold GM accountable for their poor quality of vehicles and even worse customer service!
