Ford’s safety recall 22S17 (22V193). Ford’s Field Review Committee approved safety recall 22S17 (22V193)
on March 18th, 2022 to address potential trailer brake controller concerns on production vehicles. Trailer
brake controller accessory kits can be installed by a dealer, an individual, or an aftermarket third party.
On May 20, 2022, Ford’s Field Review Committee reviewed the concern and approved a field service action.
Ford is not aware of any reports of accident or injury related to this condition.

Description of Remedy :
Description of Remedy Program : Letters will be sent to the dealer principals of the dealerships that ordered
the suspect parts for

updated. There will be no
charge for this service.
Any affected VIN’s identified as part of this program will be added to safety
recall 22S17
(22V193) and remedied under that program.
Ford will also evaluate whether potentially affected vehicles can be
identified via connected data
and subsequently updated via an OTA software update.
Ford provided the general reimbursement plan for the cost of remedies
paid for by vehicle
owners prior to notification of a safety recall in May 2021. The ending date
for reimbursement
eligibility is estimated to be August 31, 2022.
Ford will forward a copy of the notification letters to dealers to the agency
when available.

Chronology :
May 5, 2022: Ford’s Critical Concern Review Group (CCRG) opened an investigation based on information from
Ford’s Customer Service Division that trailer brake controllers sold as accessory parts “Over-The-
Counter” (OTC) for ’21-’22 MY F-150 vehicles may exhibit the same performance concerns as those included in
Ford’s safety recall 22S17 (22V193). Ford’s Field Review Committee approved safety recall 22S17 (22V193)
on March 18th, 2022 to address potential trailer brake controller concerns on production vehicles. Trailer
brake controller accessory kits can be installed by a dealer, an individual, or an aftermarket third party.
On May 20, 2022, Ford’s Field Review Committee reviewed the concern and approved a field service action.
Ford is not aware of any reports of accident or injury related to this condition.

Description of Remedy :
Description of Remedy Program : Letters will be sent to the dealer principals of the dealerships that ordered
the suspect parts for
which there is no traceability. Dealerships will be instructed to contact
customers that received
over the counter parts. Customers who have the trailer brake accessory kit
installed in their
vehicle will have the integrated trailer brake control module software
updated. There will be no
charge for this service.
Any affected VIN’s identified as part of this program will be added to safety
recall 22S17
(22V193) and remedied under that program.
Ford will also evaluate whether potentially affected vehicles can be
identified via connected data
and subsequently updated via an OTA software update.
Ford provided the general reimbursement plan for the cost of remedies
paid for by vehicle
owners prior to notification of a safety recall in May 2021. The ending date
for reimbursement
eligibility is estimated to be August 31, 2022.
Ford will forward a copy of the notification letters to dealers to the agency
when available.
