Risk if Unfixed
Wheel lock-up while driving increases the risk of a crash.
Free Fix
Dealers will install transmission control module monitoring software, free of charge. Owner notification letters were mailed April 7, 2025. Owners may contact Cadillac customer service at 1-800-333-4223 or Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N242480630.
The tire pressure monitoring system in your vehicle has a problem with the sensors that detect low tire pressure. They're using the wrong frequency and won't alert you if your tire pressure is low.
Risk if Unfixed
Driving with low tire pressure can affect how your vehicle handles, which can increase the risk of an accident.
Free Fix
You'll get a notice from GM, and they'll replace all four tire pressure monitoring sensors with the right ones for free. This will happen at a dealership, and it's completely free for you.

Original — What Happened
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."
Original — Risk if Unfixed
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.
Original — 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.
