The problem: a supplier provided GM with rear suspension bolts for the rear-suspension outer-camber control arm assembly that may not have been properly heat-treated. These incorrectly heat-treated suspension bolts may weaken during use over time and potentially fracture.
The hazards: the incorrectly heat-treated suspension bolts, which may be fitted to either the right or the left side of the affected 2023 Chevy Tahoe’s or 2023 Chevy Suburban’s outer-camber control arm, may fracture and misalign the rear wheel, increasing the overall risk of an accident or crash.
The fix: since either or both rear suspension bolts can be affected, GM has instructed dealers to replace both rear suspension outer control arm bolts. The General will pre-ship an initial supply of Rear Suspension Adjust Link Bolts, part number 11603317, to dealerships known to have affected Chevy Tahoe and Chevy Suburban units on their lots. This pre-shipment started on September 21st, 2023.
Note: a hold has been placed on all affected 2023 Chevrolet Tahoe and Suburban units currently in dealer inventory until the appropriate fix has been applied and properly registered with GM. Using a potentially affected Yukon for demonstrations, trading it to another dealership, or selling it is illegal under federal law until it has been properly repaired.
Note: GM put a sales hold on all affected 2023 Chevy Suburban and Chevy Tahoe units dealers currently have in inventory until the appropriate fix has been completed and properly reported in the GM system. Using a potentially affected Suburban or Tahoe in demonstrations, trading it to another dealership, or selling it is illegal under federal law until designated repairs have been applied.
