18255 Tire Pressure Monitoring System Not Properly Calibrated – 2018 Chevrolet Express & GMC Savana

NHTSA Campaign Number: 18V509
Manufacturer General Motors LLC
Components TIRES
Potential Number of Units Affected 94

 

Incorrect TPMS Calibration/FMVSS 138

If the low tire pressure telltale is not illuminated at the correct tire pressure, the driver may have less time to react to a low-tire-pressure situation, which could affect the driver’s ability to control the vehicle in certain situations and could increase the risk of a crash.

 

Summary

General Motors LLC (GM) is recalling certain 2018 Chevrolet Express and GMC Savana vehicles with certain combinations of front-tire and gross-vehicle-weight option codes. The Tire Pressure Monitoring System (TPMS) may be incorrectly calibrated, causing the TPMS warning lamp to illuminate when tire pressure reaches 37 PSI, not 41 PSI. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 138, “Tire Pressure Monitoring Systems.”
