NHTSA campaign 19V515000
Hazard
Ford Motor Company (Ford) is recalling certain 2012 and 2017 Focus vehicles equipped with 2.0L GDI gasoline engines and 2013-2014 Focus ST vehicles equipped with 2.0L GTDI engines, previously recalled under 18V-735. The affected vehicles did not have the Powertrain Control Module (PCM) updated as intended. Therefore, the Canister Purge Valve (CPV) may malfunction, possibly causing excessive vacuum in the fuel vapor management system.
Consequence
The excessive vacuum may result in an engine stall while driving, without warning and without the ability to restart the vehicle, increasing the risk of a crash.
Remedy
Ford will notify owners, and dealers will reprogram the Powertrain Control Module. Dealers will also check for fault codes and replace the CPV as needed. If the CPV is replaced, dealers will inspect and replace the carbon canister, fuel tank and fuel delivery module as necessary. The recall began July 29, 2019. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 19S22.
