GM has issued a product recall for certain units of the 2023 Chevy Blazer due to a missing left-side half-shaft retaining ring.
The problem:Â vehicles built without this retaining ring have the potential for half-shaft inner joint separation, which could result in a loss of drive power or a vehicle rollaway while the affected vehicle is parked.
The hazards: if the half-shaft inner joint were to be separated, affected vehicles have an increased risk of a serious crash.
The fix: certified GM technicians will be instructed to inspect half-shafts and add the retaining ring necessary, all free of charge.
Affected components: left-side half-shaft retaining ring.
Affected vehicles:
Number of affected vehicles: GM believes there are only 10 vehicles affected with this issue, although the Chevy Traverse is also included in the recall.

I just did a search and so far it seems like mine is unaffected. It may just not be updated yet though. I have a 2023 2LT with a 2.0T that was built in August 2022. It was one of the first ones to hit the lots. I am thinking that it could be unaffected because it is a 4 cylinder. Since the Traverse is also affected I am thinking it may only affect the 3.6L. I may be wrong, but I don’t believe the Traverse is offered with the 2.0T. This recall is probably more dependent on the transmission than the engine, but even though both engines have a 9 speed automatic they are actually different transmissions depending on the engine.
This recall could also be dependant on when the vehicle was built. With mine being such an early model that could also be the reason it is unaffected. I hope everyone who is affected is treated well and the fix is easy. It sucks having to take your new vehicle in for something like this and the dealership try to keep it for 3 or 4 days.
This will cause an accident. Waiting for a 2nd reply on a denied claim by GM not standing behind their faulty transmissions.
How can nobody notice this before installing it in the car.
Sad part caused my daughter boyfriend to crash at low speed. Gm denied the responsibility that or the investigation was lack there of. Now there should be no question asked. Gm dealership should never reject to fix a warranty item. If I show you the damage of this car you would be floored on how airbags blew at such a low speed. Transmission locking up caused airbags probably caused the deployment. The report of airbags said it rolled over.
I am a retired chassis manufacturing engineer with 35 years experience working at two OEMs. I know this issue well. It has nothing to do with the transmission. On the inboard end of the halfshaft spline there is a retaining ring. On the powertrain dress line, an operator picks the halfshaft out of dunnage and inserts it into the transmission with enough force to seat the retaining ring into the differential spur gear. Their assumption is that the part is good as received from the supplier, ie: the retaining ring is in place. We developed a special spade tool for the operator to pull back outwards to confirm the ring is seated. This tool is tied to the conveyor line control so if it fails to confirm a seated ring with an ‘OK’ signal, the assembly line will stop in station and alert the team leader.
This recall leaves two questions. Why was the retaining ring missing and why did the assembly line error proofing not catch it?
Without a retaining ring the axle halfshaft spline could slide out of the spur gear at some later time. If this doesn’t happen before the end of line vehicle roll test, then it could happen in customer hands . One front wheel will free spin, the other is no longer locked to the transmission. It is the same scenario as if one wheel was on glare ice. The vehicle can not drive forward. Worse yet, if an owner puts the car in Park, it can roll because the spur gears will spin.
The transmission has nothing to do with it. The fix is simple – install the missing retaining ring on the end of the halfshaft. The tough part is disassembling the lower control arm and knuckle to pull the halfshaft out for inspection.
Thanks for the break down. The car didn’t roll it hit a parked car because the car swiped. Happened 2 doors down from my house. Transmission fluid leaking prior to impact of parked car. Transmission explode transmission parts all over the ground. The guy damage is nothing more than a minor scrape. Gm denied repair. Sad on the dealership part. Warranty issue. I report on failure never presented.
Made in Mexico.
This should have been made in Lordstown.
