The Tire Pressure Monitoring System was not programmed correctly at the factory
This could lead to an accident due to improperly inflated tires
Only the vehicles equipped with 20 or 22-inch tires are affected
The issue is that the Tire Pressure Monitoring System (TPMS) could fail to warn the driver of low tire pressures, which could lead to an accident by altering the handling characteristics of the truck. Driving with low tire pressures can also lead to premature and irregular wear of one or more of the tires.
According to Ford, the problem is caused by the body control module that has been improperly programmed in vehicles equipped with 20 or 22-inch wheels. This amounts to 2,666 electric pickups in the United States and 220 in Canada. The standard 18-inch wheels are not subjected to this campaign.
The module in these trucks was programmed to set the low tire pressure warning light threshold at 35 psi instead of the correct 42 psi, which means that a tire could lose up to 7 psi of air before the driver is notified of the problem.
The automaker briefed its dealers yesterday and drivers of the affected trucks will begin receiving letters through the mail and notifications on the FordPass app today.
Owners who want an immediate fix can visit their local Ford dealer who will reprogram the body control module free of charge in about 20 minutes.
For those who prefer not to have to go to the dealer, Ford says it will make the fix available for every affected truck in an over-the-air update that will be released in the next 30 days.
