NHTSA's recall notice
As NHTSA's recall record states it for campaign 18V509000.
Defect description
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."
Safety consequence
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.
Manufacturer remedy
GM will notify owners, and dealers will check the PSI information on the remote control door lock receiver (RCDLR) and tire placard match, and if the information is different the RCDLR will be reprogrammed. This repair will be done free of charge. The recall began August 27, 2018. Owners may contact Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GM's number for this recall is 18255.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
