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.

Loss of Motive Power
On September 15, 2023, the Office of Defect Investigation (ODI) opened this Recall Query (RQ) after receiving 98 consumer complaints alleging loss of motive power in model year (MY) 2012-2018 Ford Focus vehicles. The RQ focused on the effectiveness of the remedies of Recall 18V‑735 and 19V‑515. In October 2018, Ford issued Recall 18V‑735, which updated Powertrain Control Module (PCM) software in MY 2012-2018 Ford Focus vehicles equipped with 2.0L GDI engines built prior to April 13, 2017, and those with 2.0L GTDI engines built prior to February 2, 2018. The recall addressed vehicles experiencing a malfunctioning Canister Purge Valve (CPV) that can stick open and PCM software that does not adequately detect a stuck-open CPV condition. A CPV that is stuck open can cause excessive vacuum in the fuel vapor management system, potentially deforming the fuel tank, collapsing on itself. This deformation of the fuel tank can cause a Malfunction Indicator Light (MIL) to illuminate, an inaccurate or erratic fuel gauge indication, drivability issues, and/or loss of motive power. In July 2019, Ford issued Recall 19V‑515, which addressed certain MY 2012 and MY 2017 Ford Focus vehicles equipped with 2.0L GDI and MY 2013-2014 Ford Focus vehicles equipped with 2.0L GTDI engines whose PCM software had been reprogrammed as a part of recall 18V‑735. The updated software calibrations for these subject vehicles were not properly installed by Ford at the time of production. Approximately one year after this RQ was opened, on September 25, 2024, Ford initiated a customer satisfaction program (24N07) for MY 2012-2018 Ford Focus vehicles equipped with the 2.0L GDI and GTDI engines toâas ODI learned during this investigationâaddress a different issue with the CPV from the primary focus of the safety recalls (18V‑735 and 19V‑515).  Ford stated the CPV may not operate as intended in these vehicles. A failed CPV on its own merit, may cause drivability concerns such as engine hesitation, running rough, or stalling at low speed, which will be accompanied by an illuminated MIL. This program provides a one-time replacement of the CPV for vehicles with 15 years of service or less (with no mileage restriction). This coverage will automatically transfer to subsequent owners. It is to be noted that the customer satisfaction program being taken by Ford to address this RQ investigation results in a much different and significantly less severe problem than the safety action taken to remedy 18V‑735 and 19V‑515. ODI found no further issues with the combined scope and severity related to 18V‑735 and 19V‑515 therefore, ODI is closing this Recall Query. The agency reserves the right to take additional action if warranted by future circumstances. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to

What 2018 Ford Focus owners say
Most recent owner complaints, unedited.
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.
Car doesn't start after putting in gas, has to revved to start. Leaking fluid on right front driver side. Car doesn't start in intervals throughout the day.
The contact owns a 2018 Ford Focus. The contact stated that the vehicle intermittently stalled with excessive fuel consumption. As a former Ford independent mechanic, the contact diagnosed the vehicle with a deformed fuel tank. The vehicle was taken to the dealer, where the canister purge valve was replaced under the federal safety agency Campaign Number: 18V735000 (Fuel System, Gasoline); however, the manufacturer denied coverage for the fuel tank replacement. The contact stated that the failure reoccurred. No warning light was illuminated. The contact later received notification of the federal safety agency Campaign Number: 26V369000 (Fuel System, Gasoline), and the vehicle was taken to the dealer, where the canister purge valve was replaced a second time; however, the failure persisted. The dealer notified the manufacturer of the failure. The vehicle was not further repaired. The failure mileage was approximately 180,000.
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 unauthorized bills on a federal safety recall file. I have already escalated this to Ford Corporate under Case # CXH-0831-1568-S8L7B8
Purge valve sensor and canister is malfunctioning causing my car to stall out
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 the federal safety agency 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.
The dual clutch PowerShift DCT transmission has failed. When placed in reverse, the engine RPM increases when accelerating but the vehicle does not move at all. While driving forward, the vehicle struggles to reach 10mph and the transmission slips severely. The vehicle is essentially undriveable. The vehicle has gotten stuck on neighborhood roads on 3 separate occasions due to complete loss of reverse function. I was stuck for 30 minutes to an hour which put me in way too much preassure and possibly, I could have ended up in danger. The vehicle had to be physically pushed by hand to move it. This created a dangerous situation for myself and others on the road. An independent mechanic diagnosed and replaced the clutch actuator assembly and fuel pump. After repairs the problem persists unchanged. The mechanic has noted the vehicle requires a full transmission replacement. This is a known defect with the Ford PowerShift DCT transmission affecting multiple model years. Repair costs have exceeded $1,500 with no resolution. The failed transmission puts safety at risk as the vehicle cannot accelerate properly in traffic and has no reverse function. Problem has been confirmed by an independent service center. Vehicle is available for inspection.
