Lighting-headlights - while driving at night, my headlights (both low and highbeam) will go off altogether a few seconds after I switch to my highbeams. After emergency stopping due to lack of vision, it comes back on after sitting a few moments only to happen again and again. This is a very serious defect that almost caused a head on collision and my family to loose our lives. 2) parking brake - while parked in 4 wheel drive, motor off, on a close to flat surface, my Blazer's emergency brake disengages and my vehicle has to be moved back into its paking place. Electrical system:battery - battery goes dead if I leave my door open for 10 minutes to sweep out the inside. Even after factory battery was replaced for the same reason. Exhauste system: Cvs valve replaced soon after driving off the showroom floor at dealership. Brake:hydrolic anti-lock brake assembly: Unable to stop vehicle while in 4 wheel drive causing a crash into guardrail in order to get stopped. Brakes also fail when trying to come to a stop and running over a bump in the road...causes brakes to make a clicking noise and loose braking hold...have to reapply for vehicles brakes to work.
