My experience of warranty claims with Lr has been excellent, nerver had a claim knocked back under warranty. Even had steering wheel replaced.
I have known of Toyotas owners having claims knocked with various excuses (it's normal, wear and tear, vehicle abuse etc.)
I would say Toyota are not the worst for warranty claims but they are not easy and sometimes owners have to fight.
I think Toyota will fix if they have to to keep an issue quiet? (like most manufacturers)
