2020 Cadillac CT6 recalls

Power train: automatic transmission

NHTSA campaign 25V148000 · reported March 6, 2025 · General Motors, LLC · 90,081 vehicles potentially affected

The risk: Wheel lock-up while driving increases the risk of a crash.
The fix: Dealers will install transmission control module monitoring software, free of charge. Owner notification letters were mailed April 7, 2025.

Tires: pressure monitoring and regulating systems

NHTSA campaign 19V731000 · reported October 15, 2019 · General Motors LLC · 81 vehicles potentially affected

The problem: 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."
The 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.
The fix: 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.
