4 recalls across 4 model years
The GMC T Series has 4 recalls spanning the 1984–1993 production run, with the most serious being a transmission defect on 1993 models where an internal clutch piston can prevent the park pawl from engaging, meaning the transmission may not lock the vehicle in place when shifted to Park.
On the brake side, 1984 models have a rear brake backing plate that can corrode, allowing the wheel cylinder to rotate out of position and causing partial or total loss of rear braking, which lengthens stopping distances. On 1991 models, the windshield bonding adhesive can fail to hold adequately, meaning the glass may not stay secured to the body in a crash. The 1986 model year has an incorrect tire and rim information label, which is a compliance issue rather than a mechanical defect.
