GM has issued a safety recall for certain units of the 2024 Chevy Equinox, 2024 Chevy Blazer, 2024 Chevy Blazer EV, and 2024 GMC Terrain that may be equipped with defective door strikers that were given an incorrect heat treatment during manufacturing.
Chevy Equinox, GMC Terrain, and Chevy Blazer and Blazer EV units with the defective door strikers could have their doors come open during a crash or during normal driving, raising the risk of injury to vehicle occupants. A stop delivery order was placed on December 18th, though at that time the reason was not made public.
The problem:Â affected vehicles may have door strikers that do not meet GM hardness standards for these parts. The strikers were given an incorrect heat treatment during production by the supplier.
The hazards:Â the incorrectly heat-treated strikers may fracture if placed under stress, including during crashes and during ordinary driving. If the door striker fractures and breaks, the door may open up unexpectedly during a crash or at a random time while the vehicle is in motion. This increases the risk of injury to occupants.
The fix:Â dealers are instructed to replace all four door strikers preemptively on potentially affected Chevy Equinox, Blazer, and Blazer EV units as well as on affected GMC Terrain vehicles. The GM Warranty Parts Center can supply the four necessary strikers and the necessary door striker bolts to hold them in place, offering the components as a kit.
GM has placed all vehicles indicated in the safety recall on a stop delivery order (stop sale) until the problem is repaired. Vehicles on stop delivery must not be sold, delivered to customers, used in demonstrations, or traded to other dealerships until the fix has been correctly applied and entered in the system. Repairs to customer vehicles are to be carried out free of charge to the owner.
Affected components: door strikers, which are designed to hold vehicle doors closed, and the door striker bolts which secure them.
Affected vehicles:
- 2024 Chevy Equinox
- 2024 Chevy Blazer
- 2024 Chevy Blazer EV
- 2024 GMC Terrain
Number of affected units: A total of 265 vehicles are affected by the recall, including one ICE Blazer, one Blazer EV, 201 Equinox units and 62 Terrain units. These vehicles were all built between September 13th and November 4th, 2023.
Owners should:Â owners of affected vehicles who need additional information can call Chevrolet or GMC at the customer service number listed below, depending on the brand of vehicle they own. The safety recall number can be referenced as needed to identify the issue.
- GM recall number: N232429911
- Chevy customer service: 1-800-222-1020
- GMC customer service: 1-800-462-8782

What kind of quality control protocols does gm use?
I have worked in metal fabrication at both job shops and shops that do fabrication and assembly.
Hardness is one thing that is usually checked on a regular basis at the production level.
When supplier parts or parts produced off-site come into receiving each lot should be checked again before being released for use by assembly.
In the real world screw ups like this people pay the price via corrective action, demotion and termination.
Budlar is correct. I work in the aerospace industry and quality control for 34 years. We always performed quality audits on our suppliers on an annual basis and always did quantitative QC checks of supplier parts. If we didn’t, our customers and the FAA would shut us down when they audited us. I am curious what type of quality control the big three have over their suppliers.
Sounds like GM was relying on the part supplier to handle QC checks. How the parts received an “incorrect heat treatment” is somewhat suspect, given that ISO certifications were most likely required of the supplier. Don’t know what the QC check parameters are, so it is hard to say if testing would have caught it. A simple test for hardness does not necessarily mean toughness. That would require a “test to failure” of randoms sampling of parts.
I would be surprised if a shear test is not supposed to be done.
These cars aren’t made by the UAW.
But … but ….. but I thought the UAW was responsible for ALL the defects and failures in ALL vehicles. Guess I was misinformed.
….. that’s what I get for reading the “Arkansas Trailer Park Gazette”.
AGAIN, low quality suppliers provide low quality parts. Where is your QC GM?
What did someone do? Attempt to cut cost by reducing the amount of material used to create the door striker, thinking it will still hold. Or is it truly a bad batch of parts that someone failed to check?
I’d bet it’s a combination of the two. They probably tried to get away with the cheapest possible part, but for that to work it left very little room for flaws.
Sort of like the roof on those trucks.
Yet another reason to replace Mary Barra. SMH.
