I have a Lexus now, had a tundra before. My in-laws are on Lexus number 3. He eats with guys that have a couple of Toyotas and lexuses in their friend group. They all return to the dealership for maintenance. The overwhelming consensus is that brand family is quick to develop pulsation. With both my truck and the lex, going aftermarket pads and rotors has been the way to go. their consensus is that 30k is about what they get before the dealer has to “do something” again. I’ve certainly offered to help my in-laws, but not all their friends. Don‘t want the responsibility there.Meh, I have seen no difference. Just had a 2010 RX350 come in. I did the front brakes exactly 10K ago with aftermarket pads and rotors, checked runout during install, etc. Awful pulsation. No one has touched it but me. Had a similar issue with my wife's Accord after 7K. Some combos of brake systems, pad selection and driving conditions result in this issue.
