Q&A

I bought my vehicle used in July 2010. It had 31,000+ miles, and now it has 44,100+ miles August 2011. The service department tells me that I need a tune up because it is a HEMI vehicle. My friends and family members who drive SUV's stated that they have never heard of such and that the truck isn't even "broken in" yet. I have always leased and never had to go through this. However, this time I'm keeping the vehicle and want to keep it in good condition. What do you suggest??
Also my brakes are beginning to squeal and I had rotor replacement and brake pads changed. There is a lot of brake dust on the front rims? What does that mean?
