Known issues on the 2022 CT4. Two recalls are on federal record for this model year. The first covers the roof rail side-curtain air bags, which on certain CT4 and CT5 vehicles may not have been installed correctly, so a crash can trigger improper deployment and a higher risk of injury. The second covers a lighting control module software issue in which the daytime running lights may fail to deactivate when the headlights are on, creating glare that reduces visibility and raises crash risk. Owners have filed 6 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

From an air bag module inspection to a DRL software check or routine turbo-engine service, it keeps you on the OEM procedure and the correct specification for your specific 2022 CT4.
