What can fail
The tire pressure monitoring system (TPMS) isn't calibrated correctly. Tire pressure was increased to 40 PSI, but the TPMS settings weren't updated to match, so it may not alert you to pressure problems.
What the fix does
Dealers will adjust the TPMS thresholds to the correct pressure levels to restore proper monitoring.
