General Motors issues a recall on certain 2018 GMC Savana and Chevy Express vehicles with certain combinations of front tire and gross vehicle weight option codes. The tire pressure monitoring system may be incorrectly calibrated, causing the TPMS warning light to illuminate when tire pressure reaches 37 psi, not 41 psi.
The RCDLR will be reprogrammed to obtain the correct calibration. According to the bulletin, only about 94 vehicles were affected.
