Cadillac CT4 Recalls

The Cadillac CT4 has 8 recalls covering 2020 through 2023 model years, with the most serious affecting 2020-2021 vehicles equipped with the 10-speed automatic transmission, where internal damage can cause the wheels to lock up without warning while driving.

The 2020 model year carries the heaviest concentration of issues. The roof-rail curtain airbags on 2020-2022 models may have been installed incorrectly and can fail to deploy properly in a crash, leaving occupants with reduced head protection. On 2020 models specifically, the electronic brake boost system can lose communication with its sensor due to connector contamination, causing the brake pedal to require significantly more force than normal to slow or stop the vehicle. A software fault on 2020 models can also prevent the low-beam headlights from activating at dusk when the switch is in the off or parking lamp position, and can shut off the daytime running lights while the vehicle is moving, reducing visibility in both directions.

The 2021 model year has a separate issue where the communications gateway module misreads a sensor signal and causes the airbag warning light to behave inconsistently, potentially masking a real airbag system fault without alerting the driver.

Across the full 2020-2023 production span, a software issue in the lighting control module can keep the daytime running lights active even after the headlights turn on, creating glare for oncoming traffic.
