What owners say about the fuel/propulsion system
Verbatim from NHTSA complaints, newest first
“when the vehicle accelerates too quickly or up a very gradual hill, barely any slope, it will slow to a stop. this is in line with the current recalls with other Ford focus 2018s likely caused by the Canister Purge Valve. it has the exact same symptoms, poor fuel economy, rough idling so much so the entire vehicle shakes, and the dangerous part- stalling. I have now stalled 4 times and have been in and out of multiple mechanics for this issue and no one can seem to identify the root and it's getting costly. now they are saying it might be the canister purge valve but if it is I think it should be covered despite my vin not being perfectly aligned because it's ultimately the same issue with the same vehicle, make and model.”
“There was supposedly a recall of 2012-2018 Ford focuses such as mine, which is a 2018, but somehow my car is not included in this recall even though it seems to be affected by the same problem. I believe it to have a faulty purge valve (forgive me if I am not precise in my terminology) as it stalls after I get gas and try to start it up. I have to rev the engine to get it to stay on. I cannot stop after I get it started because it roughly idles and seems like it will shut back off if I do, which makes this a little dangerous as well as damaging for my car. I am distressed that my car is not included in this recall because I desperately need to repair it before I ruin my engine but I cannot because I don't have any money.”
“I am adding a major update to my safety recall complaint because this dealership just tried to pull an illegal financial ambush on me.After my 2019 Focus started stalling out on the highway right after they did Recall 18V735, I brought it back. I explicitly told them in writing on our text thread: 'I do not authorize any standard diagnostic fees, parts, or repair charges.' I just wanted them to show me proof that they didn't pinch a wire or glitch the software during the recall work.Instead of showing me proof, they sent me a text message today saying my vehicle was 'ready for pick up' just to lure me down to the lobby. When I got there, they slapped an unauthorized invoice for $988.82 in front of my face for parts and labor. They did nearly $1,000 worth of work after I told them 'no' in writing, clearly trying to quietly fix their botched recall mistake under the table and force me to pay for it.When I showed the advisor the texts proving I denied the charges, the staff panicked and couldn't answer who authorized the job. I refused to sign it or pay it, and I walked out. My car is currently stranded on their lot because they are holding my keys hostage over…”
“The plastic gas tank was warped by heat and a faulty purge solenoid. The warped gas tank is a known issue for the 2018 Ford Focus and other versions of the car are covered by the recall, but my VIN apparently was not despite experiencing the same issue at less than 50,000 miles. The warped gas tank caused a dangerous car shutoff in traffic.”
“The vehicle was serviced for NHTSA Recall 18V735 (Canister Purge Valve/Fuel Tank stalling hazard). Immediately upon pickup from the dealership, the vehicle began severely stumbling and stalling while driving on the highway. It died while driving on the street. The dealership's diagnostic paperwork confirmed an 'O2 sensor logic error causing the vehicle to stall' right after they performed the mandatory computer software flash and valve replacement. The dealership is refusing to verify if their technician damaged the adjacent wiring harness or glitched the software flash, leaving the vehicle an active highway stalling hazard. As for my experience, The car died in Clear Lake by Baybrook Mall. Extremely high traffic, almost got hit. (Yelled at by several drivers). Constant stalling happened in Baytown. Scariest incident was going over the very tall Fred Hartman bridge. My 10 year old daughter and I felt sure it was about to die and we were going to roll backward down the bridge becauseit kept dropping power. We took the ferry home because we were so scared.”
“I replaced my canister purge valve prior to TSB or recall (18S32). Once I received the letter for reimbursement, I sent my paperwork to the dealer that performed the work (Pierre Ford Seattle on 01/05/25). They said they were going to reimburse me for the work that they did but did not. I went back to the dealer on 04/22/26 with my paperwork again. They made a copy and said they were going to submit my reimbursement. After a week or two they said that the recall reimbursement program had expired earlier this year.”
