NHTSA recall 18V509000
Tires · General Motors, LLC
Details
What's wrong: 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."
Why it matters: 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.
The fix: 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.
