What's wrong, in plain English

On vehicles fitted with certain dealer-installed 20-inch wheels, the tire pressure monitoring sensors use the wrong wireless frequency. Because of this, the system cannot turn on the low tire pressure warning light when tire pressure drops below the recommended level.

2. Contact a Cadillac dealer at 1-586-596-1733.

Official notice

Component: TIRES:PRESSURE MONITORING AND REGULATING SYSTEMS
Summary: General Motors LLC (GM) is recalling certain 2020 Cadillac CT6 vehicles equipped with dealer-installed accessory 20" x 8.50" wheels (RPO 5JO or SHH). The tire pressure monitoring system (TPMS) sensors use the incorrect wireless radio frequency and cannot illuminate the low pressure warning light when the tire pressure drops below the recommended level. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 138, "Tire Pressure Monitoring Systems."
Safety risk: Drivers may drive the vehicle with low tire pressure without a low tire pressure warning, negatively impacting the vehicle handling and increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will replace all four TPMS sensors with the correct sensors, free of charge. The recall began December 3, 2019. Owners may contact GM customer service at 1-586-596-1733. GM's number for this recall is N192279200.
