2021 Cadillac Ct5

The 10-speed automatic transmission control valve is susceptible to excess wear, resulting in harsh shifting and, in rare cases, momentary front wheel lockup. This recall affects 2020-2021 CT5 models (some early 2022 production may also be affected). The worn valve causes a gradual loss of internal pressure leading to erratic shift behavior.

NHTSA recall for TCM software update. Dealers install new software that monitors valve performance and detects wear approximately 10,000 miles before lockup could occur. The transmission is then limited to 5th gear to prevent the lockup condition. Transmission valve body replacement for vehicles with detected wear.

The DRLs may not deactivate when the headlights are turned on, affecting 2020-2023 CT5 models. This violates FMVSS requirements and creates glare for oncoming drivers, reducing visibility and increasing the risk of a head-on or lane-departure crash, especially on dark two-lane roads.

NHTSA recall for BCM software update. Dealers update the body control module, or the fix may be applied via OTA update. Free of charge.

The roof rail side-curtain air bags may not have been installed correctly at the factory on certain 2020-2022 CT4 and CT5 vehicles. Incorrectly installed air bags may not deploy properly in a side impact or rollover crash, significantly reducing occupant protection.

NHTSA recall. Dealers inspect both left and right roof rail air bags and reinstall them correctly as necessary. The repair is performed free of charge.

The Cadillac User Experience (CUE) infotainment system can experience significant lag, freezing, and unresponsive touchscreen behavior. Owners report the navigation system crashing, Bluetooth phone connections dropping, and the system requiring a hard reboot by holding the power button. The wireless phone charger may also overheat and stop working.

Infotainment system software update to the latest version. Hard reset of the CUE system. In persistent cases, replacement of the infotainment module. Wireless charger module replacement if it overheats or fails to charge.

CT5 models equipped with the 2.0L turbocharged four-cylinder engine can experience oil consumption between changes. The turbocharger seals and PCV system are potential sources of oil loss. Low oil conditions can damage the turbocharger bearings and engine internals if not caught early.

Monitor oil level regularly. Inspect turbocharger inlet and drain for oil seepage. Replace PCV valve if excessive crankcase pressure is detected. GM may authorize piston ring or turbo seal replacement under warranty if oil consumption exceeds acceptable thresholds.

General Motors LLC (GM) is recalling certain 2019-2020 Cadillac CT6, 2020-2021 CT4, CT5, and 2020-2022 Chevrolet Camaro vehicles equipped with a 10-speed transmission. The transmission may become damaged internally and cause the wheels to lock-up.

Wheel lock-up while driving increases the risk of a crash.

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 daytime running lights (DRLs) may not deactivate when the headlights are on. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."

DRLs that do not deactivate as intended may result in a glare, reducing visibility, and increasing the risk of a crash.
