Today, I had my 2009 Colorado 3LT V8 ZQ8 in for it's first oil change and tire rotation.

I also requested have the hammered-on wheel weights removed and re-balanced with the stick on weights. Well, as I suspected the wheels were marred from the hammered-on weights. Why GM would put hammered-on wheel weights on a painted wheel is anyones guess.

The service manager at my local chevy dealer told me that he couldn't replace 'em without GM's consent. So, I contacted GM customer service (800-222-1020) and opened a case.

What I find amazing it that service bulletin #07-03-10-015, instructs exactly how GM should deal with wheel appearance issues.

#07-03-10-015: General Motors New Vehicle Wheel Warranty Coverage - (Nov 6, 2007)

Subject:General Motors New Vehicle Wheel Warranty Coverage
Models:1996-2008 GM Passenger Cars and Light Duty Trucks

The General Motors New Vehicle Wheel Warranty
This bulletin has been issued to clarify warrantable conditions on GM OEM wheels. It is our intent that this one document will answer many of the warranty scenarios you are likely to encounter. Unlike other parts of the vehicle, wheels encounter various road hazards, corrosive substances and abuses that may present questions in both the mind of the customer and the dealer. Eligible conditions are warranted for the full term of the New Vehicle Warranty. Currently for Chevrolet (except Corvette), Pontiac and Saturn, this is 3 years / 36,000 miles (60,000 km) and for Buick, Cadillac, HUMMER and Corvette, coverage is for 4 years / 50,000 miles (80,000 km).

Information Sources for Wheel Issues
The following GM Service Bulletins contain information useful to minimizing possible damage, and reducing customer concerns that may arise through incorrect servicing and improper cleaning products.
• #00-03-10-002D - Chemical Staining, Pitting, Corrosion and/or Spotted Appearance of Chromed Aluminum Wheels
• #04-03-10-012A - Pitting and Brake Dust on Chrome Wheels
• #06-03-10-004 - Proper Use of OEM Service Wheel Weights, Marring and/or Damage Due to Use of Non-OEM and/or Incorrect Wheel Weight Installation
• #06-03-10-010 - Information on Proper Wheel Changing Procedures and Cautions

What is NOT Warrantable
GM provides many different styles and finishes for our passenger car and truck wheels. You will find both steel and aluminum wheels with painted, polished or chrome finishes available. While each of these types must meet GM durability standards for road impacts and finish appearance, there are conditions that are not warrantable.

Curb Impact / Scrapes
Wheels that have been damaged through abuse are not warrantable. Finish scraping and wheel flanges that have been damaged due to curb impact are not warrantable.

Bent Wheel Flanges / Cracked Wheels
Bent wheels and cracked wheels due to road hazards are not warrantable. In many cases bent and cracked wheels result from driving on low tire air pressure or a flat tire. Low tire pressures dramatically reduce the impact protection the wheel has and lowers the threshold where damage may occur.
Finish Damage / Streaking / Pitting / Corrosion

There are many different types of finish damage possible, resulting from aggressive cleaning products, road chemicals, poor tire changing practices, or manufacturing processes. Some of these are warrantable while others indicate abuse. See the Finish Damage sections below, which give examples of the different types of specific finish concern issues you may encounter.

Warrantable Issues
Any defects in the finish, balance, or structure of the wheel resulting from improper manufacture are covered under the New Vehicle Warranty for the full time and mileage limits of that warranty. Typical covered finish issues that you may encounter are:

• Flaky or pitted chrome on the visible wheel surface indicating poor adhesion of the plating.

• Polished or machined aluminum wheels that exhibit Filiform Corrosion (chalky white lines under the clear coating) This condition is warrantable, unless it is caused by incorrect wheel weight application and use.

• Wheel center caps that exhibit similar conditions to warrantable wheel concerns.

• Thin or poor paint finish quality on painted wheels. Bubbling / Flaking of the paint.

• Paint damage incurred during stick-on wheel weight changes. (See Stick-On Wheel Weight Paint Damage or Paint Flaking/Peeling Backside of Wheel)

• Flaking or peeling on backside surface of wheel indicating poor adhesion of the plating (See Stick-On Wheel Weight Paint Damage or Paint Flaking/Peeling Backside of Wheel).​

You'd think this would be a no brainer.
I'll let you know my outcome.
