General Motors has issued a recall for 81 units of the 2020 Cadillac CT6 over installation of an incorrect tire pressure monitoring system sensor. All affected units are located in the U.S., although some of those vehicles are in dealer inventory or in transit to dealers.
The defect: Affected vehicles may have been equipped with tire pressure monitoring system sensors that use the incorrect wireless radio frequency to transmit information to the vehicle. As such, the warning light may not illuminate when the tire pressure is too low. Symptoms include a tire pressure monitoring system malfunction warning light that will illuminate after driving over 28 mph for 18 minutes.
The hazards: Without a properly functioning tire pressure monitoring system, drivers who do not manually check their tire pressures may be operating a vehicle with insufficient tire pressure. Low tire pressure can negatively affect a vehicle’s handling, or result in tire failure, increasing the risk of a crash.
Affected components: Incorrect tire pressure monitoring system sensors, as installed on 2020 Cadillac CT6 vehicles equipped with certain dealer-installed accessory wheels, RPO codes 5JO and SHH (20 x 8.5 sizing, aluminum construction).
Affected vehicles: 2020 Cadillac CT6.
Number of affected vehicles: 81, all of which are located in the United States. Some of the vehicles affected are in dealer inventory and in transit to dealers.
The fix: Dealers will replace all four tire pressure monitoring system sensors with the correct sensors free of charge.
Owners should: Customers will receive a letter in the mail with notification of the defect and any special instructions needed. Concerned owners may also check their Vehicle Identification Number (VIN) for field actions in GM Owner Center here, or at the NHTSA’s website here.
