2011 Ford Fiesta electrical system problems

“I am having issues with the fuse box under the hood. I keep shorting out on my headlights ans AC clutch relay. I've purchased new head lights (bulbs), replaced them and they still didn't work. I checked the fuses after investigation online and they have blown. I had my AC completely fixed and it ran fine for a while, then stopped working. I had it checked and was told the AC relay clutch fuse was loose. I replaced it. Three weeks later it shorted out, again.”

“I am reporting a serious mechanical and safety issue involving my 2011 Ford Fiesta. After receiving a partially state-funded engine replacement in June 2025, my vehicle began experiencing serious transmission problems shortly after. Within a month, it went into limp mode multiple times, and warning lights appeared: the wrench light, incline warning, and “Transmission Malfunction – Service Now” messages. A diagnostic scan revealed multiple DTCs related to the Transmission Control Module (TCM), Input/Output Shaft Speed Sensors, and Clutch A disengagement (P286F) — which I understand are linked to known issues with this model’s transmission. These failures make the car dangerous to drive. The vehicle has lost power unexpectedly, putting me at risk of an accident. I’ve also been told by the repair shop that I may now need a new transmission and/or TCM, despite just receiving a major engine repair. I am unable to afford another large repair and this situation has severely impacted my ability to travel safely. I am requesting an investigation into the Ford Fiesta’s transmission problems and to confirm whether this should have been covered by a recall or warranty…”

“The contact owns a 2011 Ford Fiesta. The contact stated while driving at approximately 65 MPH, the vehicle stalled. The contact stated that the engine malfunction, ABS, and Hill Assist warning lights were illuminated. The contact had taken the vehicle to an independent mechanic where it was diagnosed; however, the contact was unaware of the diagnostic result. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the same mechanic who again diagnosed the vehicle and informed the contact that the vehicle was repaired. The contact stated that the failure reoccurred, and the vehicle was taken to a local dealer. The dealer diagnosed the vehicle and determined that the throttle body, engine electrical harness, and engine mounts needed to be replaced. The vehicle was repaired. The contact stated that the failure had reoccurred, and the vehicle stalled with white smoke coming from the exhaust pipes. The contact had not taken the vehicle back to the dealer. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 144,000.”

“The contact owns a 2011 Ford Fiesta. The contact stated that while attempting to start the vehicle, the vehicle failed to start as intended. No warning lights were illuminated. The vehicle was towed to an independent mechanic, who determined that there was abnormal corrosion around the wiring harness, causing an electrical fault. The vehicle was not repaired. After investigating the failure, the contact related the failure to Customer Satisfaction Program: 22N11. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 105,000.”

“I have a 2011 Ford Fiesta. The vehicle has a really serious issue relating to the fuse box that is mounted under the hood. This issue has a recall and I scheduled it for service at the Ford dealer in bryan, ohio. (Bryan Ford) I have issues with this vehicle that make it extremely unsafe for me and my family to drive. The headlights randomly go out while driving, both passenger and drivers side are affected by this. The doors will not lock and I have no horn now either, making us a target for car jacking. About a month before I found out there was a recall for this I hit a racoon and it knocked off the plastic wheel cover. After I took it in to have the recall fixed Bryan Ford refused to repair this recall due to the missing plastic. I believe my family and I are going to be seriously injured in this vehicle because of the electrical problems related to the recalled fusebox. I blow a headlight approximately once a week and the fuses blow constantly. I believe they do not want to fix this because it is a very time consuming repair that they feel isn't worth thier time. The anxiety I have while driving this car after dark is excruciating and i feel that my…”

“The low beam headlights do not turn on, all the other lights work as normal including the high beams. The fuses have not blown and there are no warning lamps or messages. This is a known problem with this make and model, there is a recall in Canada for this issue. The safety of others is put at extreme risk in any kind of low light condition (fog, rain, etc.) As well as my own safety by not being able to see in front of me. It is illegal to drive with high beams on in residential areas so I am just unable to drive at night. The vehicle has not been inspected yet. I suspect this is related to the design of the fuse box which allows debris and moisture to get into the relays, again, see the Canadian recall.”
