INDIANA – GM has issued a new service update for the Chevy Equinox, Chevy Malibu, Chevy Trax, and Chevy Cruze related to an icing issue for the engine charge air cooler.
Certain units of the Chevy Equinox, Chevy Malibu, Chevy Trax, and Chevy Cruze may exhibit a condition wherein ice or sludge will accumulate in the Charge Air Cooler (CAC) or Closed Crankcase Ventilation (CCV) system while driving in extremely cold weather, or rather, 0 degrees Fahrenheit and below.

If ice or sludge accumulates in the vehicle’s CAC or CCV system, it may result in a number of engine issues, including performance loss, an oil leak, incorrect boost levels, or various Diagnostic Trouble Codes (DTCs).
To address this issue, a GM technician will install a TCV thermal wrap on the engine and, if needed, reprogram the Engine Control Module (ECM). A new turbocharger wastegate regulator solenoid valve may also be installed. GM technicians are instructed to remove the turbocharger wastegate regulator solenoid valve, test, apply the thermal wrap, and either recalibrate or verify the ECM programming, as well as clear any possible DTCs that may have triggered.
The number of affected vehicles is unknown at this time.
Owners can contact Chevrolet directly with any concerns they may have using the contact information listed below. GM has stipulated that this service update applies to vehicles in dealer inventory and customer vehicles that return to the dealership for any reason.
