General Motors has issued a voluntary emissions recall for the 2018 model year Chevy Equinox due a problem with the airflow calibration for the vehicle’s heating, ventilation and air conditioning (HVAC) system.
The problem: according to a GM document, vehicles affected by this recall were service programmed with the incorrect HVAC calibration settings. Vehicles operating using this HVAC mode may unnecessarily deactivate the vehicle’s engine start/stop system in order to maintain cabin temperature. This may only happen in certain weather conditions – likely when the outside temperature is very cold.
The hazards: this is an emissions recall and not a safety recall, so while this problem poses no safety risks to drivers of these vehicles, the affected vehicles may emit higher-than-usual exhaust emissions if they are not repaired.
The fix: GM dealers will reflash the HVAC control module with new software. These repairs do not require any replacement parts and will be performed at no cost to the owner.
Affected components: HVAC control module software.
