Recall 18V509 covers 94 2018 Chevrolet Express and GMC Savana vehicles for incorrect TPMS calibration. Repair is free at any franchised Chevrolet dealer.
Chevrolet is recalling 94 2018 Express and Savana vans because the tire pressure monitoring system is calibrated to turn on at 37 PSI instead of 41 PSI. The late warning can leave the driver with less time to respond to low tire pressure, and Chevrolet dealers will complete the recall repair free of charge.

What's wrong?
The tire pressure monitoring system, or TPMS, watches tire pressure and turns on a dash warning lamp when pressure drops below its calibrated limit. On 2018 Express and Savana vehicles, that lamp is supposed to warn the driver before the front tire pressure falls too far below the recommended cold tire inflation value.
On affected vehicles, the calibration was set to the wrong pressure value. GM changed the recommended cold tire pressure for these vehicles but did not properly update the TPMS setting. The warning lamp turns on at 37 PSI instead of 41 PSI, so the system waits 4 PSI longer than intended before alerting the driver.
There is no warning sign before failure. The first owner-facing sign is the TPMS warning lamp, but on these vehicles it illuminates later than it should.
Who's affected?
Covers the Express and Savana van nameplates, both tied to the tire pressure monitoring system.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific van is included.
What's the safety risk?
A low tire pressure warning that does not illuminate at the correct pressure can leave the driver with less time to react to underinflated tires. In certain situations, that affects vehicle control and increases crash risk. Schedule the dealer repair soon. Repair is free at any franchised Chevrolet dealer.
What should I do?
- Check your VIN to confirm your 2018 Chevrolet Express or GMC Savana is included in this recall.
- Contact a franchised Chevrolet or GMC dealer to schedule the free TPMS calibration check and RCDLR reprogramming.
- Bring the recall notice if Chevrolet or GMC has mailed one. If not, reference recall number 18V509 when you call.
- Keep tire pressures checked by gauge until the repair is complete, since the TPMS warning lamp is calibrated to alert at the wrong pressure.
What happens at the repair
At the dealer, a Chevrolet technician checks that the tire pressure information stored in the remote control door lock receiver matches the tire placard. If it does not match, the technician reprograms the receiver so the TPMS setting matches the placard. Parts and labor are free under the recall. Out-of-pocket repairs already paid are handled through the existing warranty, not through a separate reimbursement program, since all covered vehicles are under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
