“Traction control” does not use the brakes “non-stop” to control traction.
Generally, “traction control” leverages the ABS function to stop wheelspin, which will only happen in limited situations, and then only for a few seconds. Each instance where traction control engages will put less wear on your brakes than a normal stop would. So, unless your wife is doing mad smokey burnouts all the time, it’s not the traction control that has done in your brakes.
You mentioned turning the rotors. That shouldn’t be needed in most instances. Likely, all you’re needing is new pads; the shop should check to make sure the rotor is still within tolerance, but it’s unlikely they need to be turned.
If your pads are gone within 30k miles and your wife doesn’t do a lot of stop-and-go driving, it’s more likely your wife is riding the brake with her left foot, thinking it will make her “faster” to hit the brakes in an emergency. This is a bad (and potentially expensive) habit and should be eliminated.
#14 are you proposing eliminating his wife?.... : )
