Electrical System problem #1

Purchased vehicle at the end of 2018 and this is the third time I have had to replace the horn. It's not a fuse, it's not wiring, it is the actual horn that either shorts or dies with no notice.

Electrical System problem #2

Trunk randomly pops open during driving. Or when you put it in gear.

Electrical System problem #3

My neighbor has been hacking my radio frequencies of my car and has now hacked into my car. He’s following me and controlling my car. I’m afraid he is obsessed with me and will cause my car to have an accident. The police will not and have not helped me and this guy lives right next door to me.

Electrical System problem #7

For the past 6 months, the brake lights do not come on properly and occasionally the battery drains. When this was looked into, it was found to be a bad body control module. This seems to be a common part failure issue for Ford. We need this replaced/fixed. Brake lights not working in stationary position, work sometimes while moving and battery to car drains while stationary overnight.

Electrical System problem #8

The electrical system shut down completely on the 2018 Ford Fiesta. No power, no engine, no lights, no electrical component functioned. No hazard flashers in rush hour traffic at the intersection of an interstate highway and a state highway. The car coasted and I steered it between lanes to as safe a spot as I could reach. The situation was dangerous with a high potential for harm. Fortunately no one was hurt and no accidents resulted. After a two week repair on a new car I had owned for only two weeks the cause was found to be a broken cable connector under the battery.

Electrical System problem #9

The contact owns a 2018 Ford Fiesta. The contact stated that while shifting gears after refueling the vehicle, the vehicle hesitated before returning to normal operation. The contact stated that the accelerator pedal sometimes had to be depressed multiple times before the vehicle accelerated properly. The vehicle also displayed several electrical shortages. The vehicle was taken to the dealer and diagnosed with a defective canister purge valve. The canister purge valve was replaced and several unknow repairs were performed; however, the failure persisted. The manufacturer was made aware of the failure. The approximate failure mileage was 20,000.
