Condition

Some customers may comment that the wheels are collecting an excessive amount of
brake dust.

Cause

This is due to two reasons; the brake pad material used for the brakes is a high performance material. One of the by-products of the pad material is black dust. The vehicles also
have large openings in the wheels between the spokes, which highlights the brake dust.

Wheels and Trim -- Aluminum or Chrome
The vehicle may have either painted, aluminum, or
chrome plated wheels.

Copyright 2024 General Motors. All Rights Reserved.

Keep the wheels clean using a soft clean cloth with
mild soap and water. Rinse with clean water. After
rinsing thoroughly, dry with a soft clean towel. A wax
may then be applied.
Notice: Chrome wheels and other chrome trim may be
damaged if the vehicle is not washed after driving on
roads that have been sprayed with magnesium,
calcium, or sodium chloride. These chlorides are used
on roads for conditions such as ice and dust. Always
wash the vehicle's chrome with soap and water after
exposure.
Notice: Using strong soaps, chemicals, abrasive
polishes, cleaners, brushes, or cleaners that contain
acid on aluminum or chrome plated wheels, could
damage the surface of the wheel(s) and/or the finish of
the brake caliper(s). The repairs would not be covered
by the vehicle warranty. Use only approved cleaners on
aluminum or chrome plated wheels.
The surface of these wheels is like the painted surface
of the vehicle. Do not use strong soaps, chemicals,
abrasive polishes, abrasive cleaners, cleaners with
acid, or abrasive cleaning brushes on them because

the surface could be damaged. Do not use chrome
polish on aluminum wheels.

Bulletin No.: 18-NA-067

Notice: Using chrome polish on aluminum wheels
could damage the wheels. The repairs would not be
covered by the vehicle warranty. Use chrome polish on
chrome wheels only. Use chrome polish only on
chrome plated wheels, but avoid any painted surface of
the wheel, and buff off immediately after application.
Notice: Driving the vehicle through an automatic car
wash that has silicone carbide tire cleaning brushes,
could damage the aluminum or chrome plated
wheels. The repairs would not be covered by the
vehicle warranty. Never drive a vehicle that has
aluminum or chrome plated wheels through an
automatic car wash that uses silicone carbide tire
cleaning brushes. The use of wheel cleaners or power
washers directly pointed at the brake caliper may wash
the copper paste off of the brake pads. It may be
necessary to apply the copper paste again if the
lubricant is washed away.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job
properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
