hmm...cluster...maybe its not working properly...meaning maybeeee someone changed the cluster...or pulled it out for whatever reason....check the vins...because dsc lights and brake light...i would say faulty brake line or brake changing...or lack of fluid...but you would tell automatically if there is no pressure in the brakes...next..the speedo not clocking...would ck the accelerator or throttle to see why its not sending a message to the car, but it seems simple...the cluster may not be in properly...problably forgot to plug in a harness...like when you do the chrome guage rings =D
sorry for any generalizations...but i had a friend that bought a great car from a not so great dealer.
