2018 TRD Pro with 25k miles
1) The steering wheel is peeling
2) Brakes needed replacing at 20k miles (granted I do have armor, front and rear bumper, larger tires and use it offroad a good amount)
3) Intermittent bluetooth issues between phone and Entune (this can probably be fixed with software updates on both Toyota and Android/iOS)
2016 4runner : passenger pillar squeaking. Never could get it silenced.
2019 4runner: passenger pillar still squeaking but less prominent. Front suspension squeak, dealer replaced control arms.
