2015 Ford Mustang: check engine light

Filed Dec 5, 2025 · Fuel system · CA

With only 32,885 miles, engine light came on due to (P0456) EVAP small leak. Went to an auto shop and Ford dealer for diagnostic scan. Both technicians found that there is a bit of smoke coming out from the top of the fuel tank due to a small stress crack at the port near the canister vent hose as well as a small crack below fuel pressure sensor tube. New fuel tank replacement was recommended as the crack could not be repaired. Cost to fix is $1,400 parts and $1,200 labor. This small crack nears the fuel tank seems to be a major concern for owners as it could increase the risk of vehicle fire and should be a recall by Ford for immediate remedy.

This car has been in the shop and repaired almost every year since purchase for the same part/problem. The evaporator assembly has been completely replaced twice. The first time was 6 months after purchase and only 9000 miles on the car. The most recent time this part has went out, 11/23/2021, the cabin filled with smoke while I was driving. Smelled like a camp fire so I was concerned the car was on fire. I believe if I hadn’t pulled over, the car would’ve been engulfed in flames with me inside. This is a definite safety concern, and wonder why there has been no recall on this part. Especially if the car can actually catch fire. No check engine or warning lights appeared. Just a cabin full of smoke. Ford is now saying it’s the evaporator assembly, again, and it will cost $2600 to fix. I feel this should’ve been fixed the first time. This is an ongoing problem with this car from what I’ve read and believe Ford needs to do something about it. How many lives should it cost? Mine is worth more then $2600. Should be an easy fix for a multi billion dollar company!!!
