What owners say about the electrical system

Verbatim from NHTSA complaints, newest first
“Battery randomly died. When battery was replaced at the mechanic, it caused a glitch or broke something in or connected to the transmission. Car couldn’t reverse nor go faster than 1st gear. Had to drive 11 mph all the way to the Ford Dealership. Both Meineke AND Ford Service Manager said this is a KNOWN problem with Ford Focus’ and confirmed it is a common problem. I am now being quoted $10,000 to replace the transmission.”

“I’ve had this car since 2021 and it’s been worked on 3 times for the same issues. My clutch and a couple other things for the transmission. I just recently had it worked on for transmission problems and paid $1100 for a belt replacement that didn’t even fix the issue. I told them it was clutch A like the code readers pulled (multiple times might I add) and they did a test and charged me for that test and said it was just the harness belt. Today my check engine light came on, and I had a code pulled and it was clutch A like I told them (P0902). I’ve had the actuator replaced at least twice and the power module has also been replaced. My cars engine light is on and it’s shifting hard and is taking a while to even shift. I have the invoices to show that each time it’s been worked on it’s been an issue with the transmission. My VIN number needs to be recalled before something worse happens. Each time it’s been worked on it costed me too much money especially to keep having the same problems. I’ve also done research that proves this particular issue is an issue with a lot of ford focus cars.”

“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 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.”

“While driving, the transmission went into limp/safety mode and became difficult to control. Diagnostic scan confirmed codes P0806 (Clutch Position Sensor A Circuit Intermittent) and P2872 (Clutch A Stuck Engaged). The failure is electrical — wiring harness damage near the clutch position sensor. This has happened multiple times. The vehicle is a 2018 Ford Focus SE with DPS6 PowerShift transmission. Repair estimates range from $1,500 to $2,600. The manufacturer has declined goodwill assistance despite this being a known defect on this model.”
