Engine Bearing Failure (V35A Twin-Turbo V6)

Est. Cost: Covered under recallFront Brake Squealing
Some 2024 GX 550 vehicles exhibit front brake squealing noise when driving forward or in reverse. The noise is present from new and is caused by the brake pad compound and rotor interaction. This is the same issue documented on the related Tundra platform.
Lexus issued a TSB to replace the front brake pads with an updated formulation and install improved anti-squeal shims. A brake rotor resurfacing may also be performed. Contact your dealer for the updated components.

Some 2024 GX 550 vehicles may exhibit a condition where the front passenger seat massager becomes inoperative. The massager tube becomes disconnected during use, disabling the massage function.
Lexus issued a TSB for dealers to reconnect the front passenger seat massager tube and secure it with an improved retention method. The repair is performed under warranty.

Some GX 550 vehicles built before a certain VIN (prior to a production change) exhibit abnormal hood fluttering or vibration at highway speeds. The hood moves visibly up and down, which is both distracting and concerning for owners.
Lexus issued TSB L-SB-0009-25 in February 2025 for abnormal hood fluttering. The dealer installs an updated hood cushion or adjusts the hood latch and bumper stops. Vehicles built after the production change VIN already have the improvement.

The multimedia touchscreen display may get stuck on either day mode or night mode and fail to transition automatically based on ambient light or headlight status. This can result in a too-bright screen at night or a too-dark screen during the day.
Lexus has released a software update to correct the automatic day/night mode switching logic. The dealer reflashes the multimedia head unit. As a temporary workaround, the display brightness can be manually adjusted in the settings.
