Known issues on the 2020 CT6. Two recalls are on federal record for this model year. The first covers the tire pressure monitoring system on vehicles fitted with dealer-installed 20" x 8.50" accessory wheels: the TPMS sensors transmit on the wrong wireless frequency and cannot illuminate the low-pressure warning light, so drivers may keep driving on underinflated tires without warning, degrading handling and raising the risk of a crash. The second covers the 10-speed automatic transmission, which can sustain internal damage that causes the wheels to lock up while the vehicle is moving, again raising the risk of a crash. Owners have filed 11 complaints for the year, and no technical service bulletins are currently logged. The factory diagnostic and repair procedures behind both of those systems are in this manual.
Whether you're tracing a TPMS fault after a wheel change or working through the 10-speed transmission, it keeps you on GM's own procedure and the correct spec for your specific 2020 CT6.
