1991 Chevrolet K2500 problems
The fourth generation of the C/K series is a range of trucks that was manufactured by General Motors. Marketed by the Chevrolet and GMC brands from the 1988 to the 2002 model years, this is the final generation of the C/K model line. In a branding change, GMC adopted the GMC Sierra nameplate for all its full-size pickup trucks, leaving the C/K nomenclature exclusive to Chevrolet.
Internally codenamed the GMT400 platform, GM did not give the model line a word moniker (e.g., "Rounded-Line series" for its predecessor). After its production, the model line would informally become known by the public as the "OBS" (Old Body Style), in reference to its GMT800 successor. In starting a different tradition, the model line overlapped production with both its predecessor and successor; the model line again shared body commonality with GM medium-duty commercial trucks.
Over nearly a 14-year production run, the fourth-generation C/K was assembled by GM in multiple facilities in the United States, Canada, and Mexico. After the 2000 model year, the fourth-generation C/K was discontinued and was replaced by the GMT800 platform (introduced for 1999); the C3500HD heavy-duty chassis cab model remained in production through 2002. In line with the GMC Sierra, Chevrolet subsequently adopted a singular Chevrolet Silverado nameplate for its full-size truck line (which remains in use).
