Some thing maybe to check

[RUM4MO]

I've lifted up the rear seat bases to check underneath and found that there is a module on the hatch for the fuel tank and a rubber bung that protects the leads that disappear under the base of the car (floor), due to the way this cabling has been fitted, or the way the cabling has been design or built, the cabling does not sit in the recess in the bung - so it is not getting protected but the bung, from crushing from the seat base, maybe check this out and report back as this is something that could cause problems if left in this way.

No one checked under the rear seat base yet, it might just be that the large rubber grommet needs rotating - if everything else allows that to be done. I've not checked to see if any of the seat base steel frame is located above this yet.

Same issue under my seat. Looks as if they've made one wire too long and one too short.

However, I can't see how these'll get any wear in that location even with people sitting on them, as the seat is so soft it shouldn't be an issue in my view - thanks for letting us know though

I'll get the car up on jack stands later this week (maybe) and see what I can do about this, one other thought - a bit later was, "does that bung/big grommet need rotating to improve things?

I've seen things like that a few times in new models of cars, I seem to remember commenting about a brake flexihose routing/length on an early FWD Escort and that was changed, so either a few people commented on it or Ford wised up. On my 1991 VX Cav GSI 4X4, pumping the brake pedal with the ignition off caused the brake fluid liquid level to rise and flow out of the reservoir - reporting that to local dealer had the techs in stitches at my expense, that got me a bit annoyed, not half as annoyed when the official recall for that came two years later - IDIOTS! The 4WD system used the brake fluid as its control medium, and the diaphragm in a sphere for that control was not designed correctly so allowed air to be admitted. Just to add, the handbook required you to pump the brake pedal 6 times before checking the fluid level, I discovered what happens when you pumped it for longer!
