Brake wear!!!!!!!!

2019 Exp XLT. 43000, changed rear brakes pads and rotors, and the inside brake pad was worn down completely to the metal on both sides, while the outside pad on both sides was not even worn down half way!!!!!’.

I have NEVER seen this on any of my previous vehicles. And , normally my front pads have always worn faster than the rear.

There has to be some design fault with these brake calipers!!! A small difference might be expected; however, this was ridicules..

Anyone else seen the same?????

Full size trucks usually have "harder & larger" brake pads on front and "softer & smaller" pads on the rear. Usually, rear pads are worn out faster than front on those vehicles. But inside pads shouldn't have so much difference from the outside pads, no matter on the front or rear.

If the inside pad was worn more than the outside then you caliper is not moving properly. Did you make sure to service the slide pins when you changed our the pads/rotors?

Uneven pad wear indicates an issue with the caliper. Either the guide pin(s) are frozen (as mentioned above) or the piston is bad.

So the lane assist is why the rears wear down so quickly. It uses them to steer the vehicle back into the lane.
The issue with your uneven wear may be that the caliper pins need to be greased properly. There are pins that the caliper slides in and out on, and it could be that the caliper is getting hung up on the pins.

Lane assist most likely isn't the cause. Rear pads wearing faster has just been a thing on a lot of suv's and trucks for a lot of years now. I first noticed it on my 2007 jeep wrangler. Basically, it is what Hellwig mentioned above. It's just normal but if you use a semi-metallic or ceramic pad you should see longer life out of the rear pads. The stock pads are soft and wear fast.

Your other issue is either sticking slide pins, or a stuck caliper. I am betting more along the lines of the sticking pins. Looks like you live in an area with salted roads in the winter, that can corrode those slide pins quick and cause them to hang up. They don't come lubed very well from the factory I don't think. When I do pads on my vehicles, I pull the pins and clean them up and lube them heavy with CRC brake and caliper grease.

If you leave traction control on especially when towing, the constant balancing of power to the rear wheels through the brakes will cause unusual wear for the rear brakes.

Towing isn't really the issue, in fact that might be less of an issue because there's more weight on your rear wheels.
Traction control kicks in (applies the brakes) when there is wheel slippage. In the winter on slippery streets, if you're constantly spinning your wheels (like trying to get going at a green light) those brakes will be working hard to get both rear wheels turning. Unless you have the eLSD...
My 92 Crown Vic had traction control and went through rear brakes faster because of this.

Might not be the OP's issue (or just a small part of it) - that uneven wear points to a bigger issue methinks.
