“I own a 2004 Hummer H2, and my boss owns a 2003, and my brother also owns a 2004, and all three (3) trucks have the same problem with the running boards rusting and also the wheel wells. For the money that you pay for a truck it shouldn't be rusting out, I hope that you could address this problem, I had brought my truck in for service and there was nothing they could do they gave me this site. Please contact me at your earliest convenience. Thanks for your prompt attention to this matter.”
