I dropped my car off yesterday for the 6 month service and to have them revisit the brake squeal again (they replaced the brakes about 5 months ago, but the squeal came back). I just got a call from the SA saying there's a possibility that the noise is coming from the Spidertrax spacers I have on the wheels. I call BS, but I think they're preemptively making up an excuse to not have to warranty it if they can't fix it this go around. I can't imagine how wheel spacers could be causing the problem, but maybe someone here smarter than me can chime in?

I would love to hear the dealer explain how a spacer could squeal lol

Same. Supposedly they have corporate techs looking at my car. Waiting to hear back.

I run Spidertrax spacers. Brakes squealed before I put them on and continue to do so.

Still waiting on my new brakes

A little update. They said my car has the updated parts from the replacement from a few months ago. They can’t reproduce the squeal, but they’re not saying it’s not present (it 100% is). They’re keeping the car over the weekend and tearing the brakes apart to do more diagnostics. Said something about sending pictures of the parts somewhere.

GX has been sitting for a week. Electric parking brake.........don't think it released fully causing squeals in reverse. GX felt like a drag on it starting to back out of garage.. Since the brake is automatic you would have it all the time after parking and starting. Going to keep attention on the dragging and see if that could be the cause. Seemed to go away once I step on the pedal. ??

Dealership said they got Lexus corporate involved. They’re trying to figure out why the updated parts are still squealing. Kinda using my car as an R&D.

My brake have made loud squealing noises since delivery of my GX 550 Overtrail. I have had my car about 3 months. I had similar issues with my 4Runner TRD Off-road with KDSS. The Toyota dealer eventually replaced my brake pads and the noises went away. My Lexus dealer has had my GX for over a week and are now replacing my entire brake system - pads, rotors, even my brake lines. I thought this was excessive, but I have not been told why they are doing a complete brake replacement. Lexus obviously knows more than they are telling me. Hopefully the parts will arrive soon and I will get my GX back and the noises will stop. My GX has approximately 2500 miles on it.
