Ford Fiesta check engine light comes on

Filed Sep 4, 2026 · Engine, Fuel system · CA

Check engine light illuminated. Dealer retrieved DTC P0457 for an EVAP leak. Dealer performed EVAP diagnostic testing and determined that the canister purge valve was leaking. Purge valve was replaced at owner expense. After replacement, EVAP leak verification passed and DTC was resolved. I am reporting the failure because Ford has previously identified canister purge valve failures on other Ford vehicles and I believe similar failures may be occurring on Ford Fiesta vehicles.

Ford has had a long known issue with 2011-2015-FIESTA ( Cuautitlan ) they issued a Customer Satisfaction Program that ended June 2025. I purchased the car July 2026 used w/o none issues. Checked VIN for recall and Maryland Inspected. Driving it one week and the check engine light comes on. Apparently the TCM recognized a change in driving pattern but FORD will not honor the replacement. How is it not a safety issue with the vehicle can decide not to engage risking a collision? I am willing to pay for the labor of the part but would like the part covered as it should.

I was driving for couple hours then my oil light came on check engine light came on. Vehicle started to shake very badly. I had to pull over and see what happened. I started the vehicle up again and the oil light and check engine light are still on. I know that these vehicles have the wet belt system on the automatics. But they don't have one for the manual transmission. There should be a recall for these just like the automatics.
