clean abs sensors at each wheel.

Do you hear a clicking sound around the engine when it doesn't start? Have someone try the starter while you listen carefully under the hood for the source of the clicking. If it comes from the starter/solenoid area, you will need a voltmeter or test light to test for 12 volts at the battery side of the solenoid (light on or 12 volts always while attempting to start). If light goes out (12 volts goes to zero), then replace the positive battery cable that connects at the solenoid. Next test is at the solenoid other heavy terminal that connects directly to the starter motor. If the light never goes on (12 volts never appear) during start, the solenoid is bad and should be replaced. If light comes on (12 volts appears), then the starter motor is bad and should be replaced. (It likely has a dead spot in the commutator.)

Rapid flashing is generally down to a bulb being out on the side it effects, due to the resistance being altered, does the side repeater and the front flasher flash fast as well? Try changing all bulbs on that side

Ranjit,

I have the same problem with my 2008 Hummer H3. I had the front and rear rotors resurfaced. I am now thinking of getting the rotors replaced with bigger more durable rotors. Solution about the sticking brake caliper sounds about right if you hear a grinding noise as you drive without even touching the brake pedal.
