Open the full vehicle complaint log (all categories)Okay, I can press the gas and try to go one speed.And my car will go either way, too slow for that gear or way too fast.For that gear , I have almost been several wrecks , because it's either going too slow , went when i'm supposed to be going to certain speed or it's going to fast one supposed to be going to certain speed
MY CHEVROLET SPARK CANNOT DECIDE WHAT GEAR IT WANTS TO BE IN, CAUSING DELAYS THAT ARE DANGEROUS WHEN PULLING OUT IN TRAFFIC OR TURNING ACROSS LINES OF TRAFFIC. FOR INSTANCE, I SLOW DOWN TO GET INTO THE CENTER TURNING LANE OF A 5-LANE STREET AND THEN WHEN CLEAR, I ACCELERATE TO MAKE THE TURN. THE CAR FEELS LIKE IT MAKES A SHORT STALL AS IT CAN'T DECIDE IF IT NEEDS TO GET INTO A HIGHER OR LOWER GEAR. IT CLEARLY TAKES A LONG TIME AND GOES UP AND DOWN WHICH PLACES ME UNCOMFORTABLY TOO CLOSE TO ONCOMING TRAFFIC. OTHER TIMES WHEN I PULL OUT IN TRAFFIC, THE SAME SCENARIO REPEATS. I WONDER IF IT SHIFTS INTO A TOO HIGH A GEAR TOO SOON THEN DOWN SHIFTS ONE GEAR AND THEN UPSHIFTS AS THE CAR STARTS TO ACCELERATE. SEVERAL TIMES A DAY WHEN I SLOW TO ADJUST TO TRAFFIC CONDITIONS AND THEN ACCELERATE AFTER SLOWING, THE CAR LAG/STALL HAPPENS AS THE TRANSMISSION SHIFTS UP AND DOWN THROUGH THE GEARS. THE CAR JUST CAN'T DECIDE WHAT IS THE BEST GEAR TO BE IN. I FEEL THAT THIS IS DANGEROUS. IT CERTAINLY MAKES ONE VERY UNEASY WHEN YOU PULL OUT IN TRAFFIC AND THEN THE CAR BARELY MOVES FOR A VERY CRITICAL SECOND OR TWO.
