1 Exterior Lighting problem of the 2015 Ford C-max

Failure Date: 05/23/2025

When I went to the garage, I noticed my brake lights were on, but the ignition was not. I tested the car, it started without me stepping on the brake. I could also move the car out of park without stepping on the brakes. I thought the switch on the brake pedal had failed and so I took it to my mechanic for replacement. The mechanic tested the switch and found it okay. However, he had seen the same problem in other Fords (recall # 22v-011 or 22s02) and it involved the pedal stop bumper deteriorating. The recall indicated it would replace only the pedal stop bumper. My mechanic said that replacement part wasn't available to them. So, I took it to the dealer hoping that since I had the same problem, I was included in the recall. My C-max was not listed. They said that that the pedal stop bumper replacement part wasn't available for my car, and that they would have to replace the entire brake pedal system for an outrageous $1400. I had little choice, and so I agreed with the hope that Ford would provide some relief. They didn't. Instead, they said hang onto the receipts and maybe someday there will be a recall, and I'll be reimbursed. So now I'm writing you. Clearly, this was considered to be a safety hazard in the other Ford products, and I believe it to be exactly the same in mine: brake lights always on are a safety hazard as well as being able to shift the car out of park or start the car without depressing the brake. Moreover, the battery will run down unless I disconnect it at night. Basically, my car is unsafe to drive without this repair.
