General Motors recommends 2019 to 2022 model-year Cadillac XT4 owners use the vehicle’s winter grille cover in extremely low temperatures to prevent the charge air cooler from accumulating ice.
The winter grille cover is included with 2022 model-year Cadillac XT4 models that were ordered with the block heater (RPO code K03). Using the cover will prevent ice from gathering on the charge air cooler, which may “restrict air flow, resulting in a loss of power, hesitation on acceleration and other poor performance conditions,” according to GM.
The automaker referred to a service bulletin issued for the Buick Encore in April of 2019 that sought to address owner complaints of power loss, a stalling condition and other issues in extremely low temps, which were eventually tied to the charge cooler freezing over.
A one-time installation of the grille cover is covered under warranty for up to 12 months after vehicle delivery for 2022 models, but owners can also install the grille cover themselves. Installation information is included in the grille cover instruction sheet and the Owner’s Manual, the automaker says. The winter grille cover should only be used in extreme cold weather and should be removed when the winter season changes and temperatures rise above temperatures above 0°F or -18°C.
Customers who own a Cadillac XT4 without the winter grille cover can order it via a GM dealership. As noted above, the winter grille cover is included on 2022 model-year Cadillac XT4 vehicles that were ordered with the engine block heater, which is a $100 option.
GM recently launched the online configurator tool for the 2022 Cadillac XT4, allowing prospective buyers to customize the crossover and view a complete pricing breakdown. Just as with the previous model year, power in the 2022 Cadillac XT4 comes from a turbocharged 2.0L I4 LSY gasoline engine, which mates to a GM nine-speed automatic transmission. Front-wheel-drive is standard while all-wheel-drive is available for a price premium.
The 2022 XT4 is built at the GM Fairfax Assembly plant in Missouri.
