Brought GX in today for 5000 mile complimentary service. I advised that my brakes were squealing loudly when puling out of the driveway in reverse. I was advised there is a TSB regarding this issue and they are keeping my vehicle overnight. Can someone link this TSB, please? I could not find it. so far, these are all I could find:

Club Lexus TSBs

Additionally, the gasket around cargo opening is slipping off just above the bumper. Appears to be an adhesive issue.

I also complained about the wind noise of the factory roof rack.

Dealership did not contact me, so I called them. they still have my GX with only 5K miles. They are ordering parts and could not tell me more. I assume it is the brake squeal but no one can tell me the substance of the TSB. WTF.

I still canot find the TSB but, according to dealer, there is one coming up for improper brake pads and shims. They are replacing the shims and pads on LCs and LXs. Parts are on order.

My GX550 OT has the same brake squealing when backing up. My service advisor at Lexus dealer wasn't aware of any TSB or service advisory for the brake squeal, so i've had to dig into the issue and try to educate them...very frustratig. Only thing i've found about it is from the Lexus GX550 Forum ( Squealing Brakes 550 Overtrail - https://www.lexusgxforum.com/threads/squealing-brakes-550-overtrail.635/ )where it's been discussed at length. The attached screen shot is from the GX550 Forum and shows TSIB # L-SB-0036-24:

My OT had the singing brakes. Parts were on back order for a couple weeks. Longo completed my GX yesterday (25 Oct) per the bulletin. Issue resolved.

Squeaky brakes here too. Took a few thousand miles before I noticed. Dealer replacing front rotors, pads, and shims. Lexus has a kit for this. It's a 2-part visit. One for confirmation of the issue. Another for the replacement once your individually ordered kit arrives. Lexus supposedly doesn't let the dealers stock kits: it's truck by truck; part order and a wait for each.

New cars get washed a LOT at the dealership. Decent chance they washed the grease off the backs of your brake pads where it contacts the piston.

Nope. It is a design problem. still have not had mine repaired.

The brakes on my 250 were squealing loudly when backing up. Took it in and they found built up brake debris between one of the rotors and the pads. Cleaned that out and they are quiet again. Will post up if it isn't resolved long term. They also resolved a rattle with one of the long covers to the side of the hybrid battery. A little felt tape and all is right in my world.
