The short answer
NHTSA received General Motors LLC’s report on Aug 2, 2018. Copied from NHTSA on Oct 19, 2026.
Every line below is in NHTSA’s own words, with its source beside it.
What’s wrong with it?
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.
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.”

What the record doesn’t say

- Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
- How many have been returned or fixed isn’t in the notice.
