Haunted. Yes. Haunted.

Now I have your attention, does anybody know why or have the same issue as this?

My Brake lights decide to stop working occasionally. Like they will be on and fine for a while, then they stop working and start working again when they feel like it. We have replaced light bulbs, fuses and the switch multiple times and have had Mechanics and Auto Electricians look into it with no answers. 9/10 I take it in and the lights are working fine so they can't do anything. I've had an auto electrician check wiring and it appears to be fine. Also had somewhere near the switch solded, which fixed the issue for a few months but now it's turning off more often so that hasn't helped either.
This issue has been going on for a year now and I'm well and truly over it.

Factory, nothing has been added or removed from the car. All the lights go out so 5 in total. They won't work for say an hour then when I drive the car again they will work. Nothing says it's not working. I can only tell at night due to reflections, signs etc

You have all the brake lights working fine or no brake lights when the BL system goes down.

It looks very much like the brake pedal is intermittently not activating the brake light switch for some reason so none of the BRAKE lights come on when you press the pedal. If you have changed the switch itself then that unit should not be suspect.

Id have thought the brake light switch but since you have replaced all of that its probably time to go looking at the wiring harness. If its got a tow bar, check the trailer plug wiring where it splices in first. Then on to the earths....and then the rest.
I had a grand cherokee that was similar...turned out the wiring harness had worn through where it ran under the drivers seat...interior lights would do wierd things. Took an age to find that little sucker.
