Known issues on the 1991 D21. Three recalls are on federal record for this model year, all tied to aftermarket parts fitted to these trucks. Two cover replacement lighting: certain combination headlight and corner/bumper lamp assemblies sold for these vehicles lack the required amber side reflectors, which can leave the truck poorly illuminated and increase crash risk in low visibility. The third covers the front seat belt buckle release button, which can break and let pieces fall into the buckle assembly, causing it to operate improperly and fail to protect an occupant in a crash. The factory diagnostic and repair procedures behind each of those systems are here.

From verifying replacement lighting compliance to inspecting the front seat belt buckle assembly or working through routine KA24E or VG30E service, it keeps you on the OEM procedure and the correct specification for your specific 1991 D21.
