TRANSMISSION IS NOT ABLE TO BE FIXED. THREE REPAIRS AND GM CAN'T FIX. TRANSMISSION JERKS, SLIPS, CLUNKS. UNCOMFORABLE TO DRIVE. I AM STUCK WITH SUBPAR VEHICLE. GM HAS BEEN HORRIBLE TO WORK WITH. 17 RECALLS? WHY CANT GM MAKE A SOLID RELIABLE VEHICLE AFTER 100 YEARS IN BUSINESS?
WHEN COMING TO A STOP, APPLYING A STEADY AMOUNT OF BRAKE PRESSURE THE TRANSMISSION SHIFTS AND LOSES ALL FORMS OF ENGINE BRAKING CAUSING THE TRUCK TO SPEED UP AND OVERSHOOTS THE STOPSIGN.
INTERIOR DASH LIGHTS GOES OUT AND A FEW MINUTES LATER THE ENGINE CUTS OFF WHILE I'M TRYING TO PARK. EACH TIME WHILE I WAS BACKING INTO MY PARKING SPACE. AFTER SITTING FOR ABOUT 30 SECONDS THE LIGHTS DASH BOARD LIGHTS COME BACK ON, THEN I RESTART THE TRUCK. SOMETIMES WHILE DRIVING THE DASH BOARD LIGHT BLINK OF AND ON.
STARTING THE VEHICLE I'M PUTTING THE TRUCK IN REVERSE, THE TRUCK LUNGES BACKWARDS. ALSO A VIOLENT JERK OF THE VEHICLE HAPPENS. THIS HAPPENS A MAJORITY OF THE TIME. PUTTING THE VEHICLE INTO GEAR TO DRIVE I HAVE A VIOLENT JERK AND A LOUD NOISE. THE TRUCK DOES NOT LUNGE FORWARD WHEN PLACING THE TRUCK INTO DRIVE. THIS HAPPENS A COUPLE OF TIMES A DAY. THIS IS NOT AN ISOLATED INCIDENT.
