One problem related to carrier/rack has been reported for the 1999 Chevrolet S10. The most recently reported issues are listed below.
The cable that holds the spare tire to the underbody near the rear of the truck box broke. Fortunately, the truck was parked in my garage and I found the spare tire on the floor under the truck. If the cable holding the spare tire had broken while driving, the spare tire would have been a serious hazard to traffic following me. I have never used the spare tire hoist assembly. The cable that holds the spare tire broke for no apparent reason.
