GM has released a service bulletin for a fix to a missing structure plug in certain affected 2023 Chevy Malibu sedans, with one of the plugs missing from its hole in the sheet metal structure on the passenger side.
Dealerships are instructed to check for the problem both in 2023 Chevy Malibu units currently in their inventory and on any vehicles brought in for any type of servicing.
The missing structure plug can be readily detected by direct visual inspection of the structure plugs on the passenger side of the 2023 Chevy Malibu sedan dash. Inspection is estimated to require 42 minutes to complete, not counting plug fitment if needed.
Additionally, dealer service personnel should verify the unit’s involvement by checking to see if it is marked “Open on the Investigate Vehicle History screen, available through the GM Global Warranty Management system.
If the passenger side structure plug is missing, the dealership service personnel should install a new plug in the round opening in the metal. GM notes that the problem is rare and the structure plugs have a low supply, so dealers should not order the plug as shelf stock, but wait until an affected 2023 Chevy Malibu is located.
The fix is available free of charge to the Chevy Malibu’s owner until the end of the affected sedan’s New Vehicle Limited Warranty period. Actual installation of the plug requires an average of 6 minutes according to GM, or 48 minutes with inspection included.
