disgruntled

Hi all I recently bought a A Class aA250 w176 2012 plate with 49 tho on the clock, had the car 3 months when I got a warning on the dash telling me to check pads for wear. So took my car in only to be informed I also needed new disc's as well Grrrrr At a cost of £325.00 I was none to chuffed...

Will this become a normal practice? Asking for compensation because maybe your car is going to blow up. I fell so sorry for Porsche :( Disgruntled Porsche GT3 owners demand compensation...
