A winter grille cover is available to restrict airflow in extremely low temperatures.

Some owners of 2019-2021 Cadillac XT4 vehicles equipped with a 2.0L gasoline turbo engine may comment on one or more of the following conditions when driving in extremely cold weather (zero degrees Fahrenheit or less):

- Loss of power

- Hesitation on acceleration

- Stalling condition

- MIL illuminated

DTCs P0299 and/or P2227 may be set.

This condition may be caused by ice accumulation in the charge air cooler (CAC), restricting airflow. A winter grille cover has been released to address this issue.

After the technician initially installs the grille cover, the customer needs to be educated on the removal process after winter season ends and how the customer will reinstall the cover the following winter season. The winter grille cover is available as P/N 85513002.
