What's wrong?
The left-side front-wheel-drive half-shaft on the 2023 Chevrolet Traverse and Blazer is a metal drive shaft that carries engine power from the transmission area to the front wheel. A retaining ring is a small locking ring that helps keep the half-shaft seated in the correct position. When it is present and fitted correctly, the shaft stays aligned while the suspension and steering move.
On affected vehicles, the left-side half-shaft assembly was built without that retaining ring. GM traced the issue to a supplier quality control error during a short July 2022 manufacturing window, which allowed affected assemblies to pass inspection. Without the ring, the shaft is not held the way it was designed to be held, so movement at the front driveline can create abnormal contact or noise.
Drivers can hear a grinding or clicking noise from the front of the vehicle. That sound is the warning sign GM identified for this defect.

A matching 2023 Chevrolet Traverse or Blazer does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific SUV.
What's the safety risk?
A missing retaining ring can let the half-shaft inner joint separate. That can cut drive power or let the vehicle roll away after it is shifted into park. Either failure increases crash risk. Listen for grinding or clicking from the front of the vehicle, then schedule the repair promptly. Repair is free at any franchised Chevrolet dealer.
What should I do?
- Check your VIN to confirm your 2023 Chevrolet Traverse or Blazer is included in this recall.
- Contact a franchised Chevrolet dealer to schedule the free left-side half-shaft assembly replacement that fixes the missing retaining ring and prevents inner-joint separation.
- Bring the owner letter if you have it, and reference recall number 23V042 when you call.
- Limit driving until the repair is complete, and set the parking brake each time you park.
What happens at the repair
At the dealer, a Chevrolet technician replaces the left-side half-shaft assembly with a corrected assembly so the retaining ring issue is addressed. The replacement parts and labor are free under the recall. Out-of-pocket repairs already paid are handled through the existing warranty, not through a separate reimbursement program, because the covered 2023 Traverse and Blazer vehicles are under warranty. If you have prior repair paperwork, ask the service desk how the vehicle's warranty applies.
