What's wrong?
The tire pressure monitoring system on the 2020 Cadillac CT6 uses sensors inside the wheels to send tire pressure information wirelessly to the vehicle. When tire pressure drops below the recommended level, the system is supposed to turn on the low-pressure warning light so the driver knows to check the tire.
On affected CT6 vehicles, the problem is tied to dealer-installed accessory 20 x 8.50 wheels, RPO 5JO or SHH. The sensors installed with those wheels use the wrong wireless radio frequency for this vehicle. Because the car is listening on the intended frequency, it does not receive the low-pressure signal correctly. That means the low-pressure warning light does not turn on when a tire is underinflated.
An owner can still see a different warning. A TPMS malfunction light will illuminate after the vehicle is driven over 28 mph for 18 minutes, which points to the sensor communication problem rather than a specific low tire.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific sedan.
What's the safety risk?
A TPMS fault can leave the driver without a low tire pressure warning, so the CT6 can be driven on an underinflated tire until handling is affected, increasing crash risk. A TPMS malfunction light comes on after sustained driving over 28 mph. Schedule the sensor replacement promptly. Repair is free at any franchised Cadillac dealer.
What should I do?
- Check your VIN to confirm your 2020 Cadillac CT6 is included in this recall.
- Contact a franchised Cadillac dealer to schedule the free TPMS sensor replacement that restores the low tire pressure warning for the accessory wheels.
- Bring the recall notice if Cadillac mailed one. If not, reference recall number 19V731 when you call.
- Check tire pressure manually until the repair is complete, and keep the tires inflated to the recommended pressure.
What happens at the repair
At the dealer, a Cadillac technician replaces all four tire pressure monitoring sensors with the correct sensors so the low pressure warning system uses the right wireless frequency. The recall repair is free, with parts and labor covered. Out of pocket repairs already paid are handled through the existing warranty, not through a separate reimbursement program, because the covered vehicles are under warranty. Ask the Cadillac service desk how warranty coverage applies if you have prior repair paperwork.
