Known issues on the 2020 CT5. Four recalls are on federal record for this model year. The first covers the roof rail side-curtain air bags, which may have been installed incorrectly and can deploy improperly in a crash. The second covers the electronic brake boost system, where sensor connection contamination can interrupt communication and cost the driver brake assist, requiring extra pedal force to stop the car. The third covers a lighting control module software issue where the daytime running lights may fail to deactivate when the headlights are on, causing glare that reduces visibility. The fourth covers the 10-speed automatic transmission, which can sustain internal damage that locks up the wheels while driving. Owners have filed 38 complaints for the year, and no technical service bulletins are logged for the year. The factory diagnostic and repair procedures behind each of those systems are here.
Whether you're chasing a brake-assist warning, a DRL that won't shut off, or a transmission fault code, it keeps you on the OEM procedure and the correct specification for your specific 2020 CT5.
