Summary

Some 2022 Maverick and 2020-2022 Escape vehicles equipped with a 2.5L full hybrid electric vehicle (FHEV) powertrain may exhibit an idle surge and/or rough idle with high temperature in the catalytic convertor and sulfur odor in the cab. This may be due to the software installed in the powertrain control module (PCM). This condition does not affect vehicle durability and no additional diagnosis or service is required for this condition at this time. Inform customers that they can continue to drive the vehicle and engineering is currently developing a software update that is expected in the last week of March 2022. Once the software update is available, contact the customer and schedule a follow-up appointment for repair. Monitor OASIS for updates.

Owners of these vehicles have filed 257 complaints in the electrical category.
