Wiring problems of the 2007 Ford Focus

Wiring inside of boot to the hatchback (liftgate), powering the third brake light, lock for hatchback, and rear wiper is broken causing shorts.

Tl-the contact owns a 2007 Ford Ford Focus. The contact stated that while driving at various speeds, the air bag warning light illuminated. The vehicle was taken to a dealer where it was diagnosed that the air bag wiring and clock spring needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 100,000. Ss.

Rear taillight bulb blows out as if an electrical short in wiring. Bulb will look black, even the socket has black discoloration. This has been an on-going problem since we purchased car in 2009 with both the left and right rear tail lights. To date I have replaced about 15-20 bulbs to the extent I purchased two (2) boxes of bulbs a socket wrench and correct socket to keep in car to replace bulbs each time it happens.

Dashboard and running lights going out. Replaced blown fuse and then fuse blows again. Opening and closing the hatchback the lights came on and then off again and the replaced fuse was blown. Located a bundle of wires within a rubber hose that runs from the interior roof headline outer rim of the vehicle across to the interior top of the hatchback. We pulled down this rubber protector to find to our complete amazement that the bundle of wires that run to the hatchback brake light and the hatchback windshield wiper was broken and burnt. Thought that there was a possible loose connection that just needed to be snapped back together, but only to find a bundle of broken and burnt wires wrapped tightly together, plus there was no black wiring tape around the wires for extra protection. Just the wires tightly bound together. Little to none flexibility for the bending or movement for these wires. These wires are located in an area where there would be movement due to opening and closing the hatchback. Contacted the local dealership and spoke with the service manager. He stated that the wire bundle have been made short in some vehicles. Our concern:potential fire hazard and still maybe until fixed; concern are for other individuals who may own this type of vehicle that may be transporting passengers (to include children in car seats) in the back seat (which there is no back side passenger doors) that could have a difficult time exiting this vehicle should it go on fire due to these bundle of wires possibly catching on fire and igniting the interior roof headliner of the vehicle. We have not taken our vehicle into the dealership as we are waiting on a response from Ford motor company. Additionally, the dealership stated that we would have to pay a portion to repair (what we believe to be a faulty design and defect) to correct this problem. Pictures available. ## VIN failed ##.

The contact owns a 2007 Ford Focus station wagon. The contact was driving 45 mph when he noticed that the tail lights and marker lights were no longer illuminated. The vehicle was taken to a mechanic who informed him that the wiring harness was chafe and had a short circuit. The vehicle was not repaired. The dealer advised that there were no recalls for the failure however, there was a technical service bulletin under NHTSA item number: 10023297 (electrical system: wiring). The contact did not order the service bulletin for additional information. The failure mileage was 120,000.

2007 Ford Focus wagon with all the wires (about 10 of them) in the body to liftgate wiring harness cracked or broken. Found due to brake lamp fuse blowing repeatedly, causing loss of all brake lights and a/t shift lever interlock operation. It might have gone unnoticed if it wasn't for the interlock not working. Car is off warranty so Ford will not fix unless I pay for it. This is a definite safety item in my opinion. I will replace the wires myself as I am an aircraft electrician. I will use a better quality wire too. The stuff Ford uses is not meant to move and flex repeatedly. Wiring should last the life of a car.
