My truck keeps showing lights and is displaying that the crash collision is disabled.
Blind spot warning becomes disabled sporadically? Engine needs to be turned off and restarted to reconnect Blind Spot Warning. This has been an ongoing problem for the last few years. It never shows up when brought into dealer for inspection? Nor are there any computerized “messages” in the system? The below “Additional Details” only reflect yesterday’s occurrence. This problem happens on a regular basis. with no regularity?
DRIVING ON HIGHWAYS OR INTERSTATES WITH THE ADAPTIVE CRUISE CONTROL IS WHEN THIS HAPPENS. THE FIRST TIME I WAS DRIVING ON A SWEEPING LEFT TURN AND COMING UP FAST ON A TRUCK IN THE SLOW LANE I WAS DRIVING IN, SO I PUT ON MY BLINKER AND MADE A QUICK LANE CHANGE INTO THE FAST LANE TO GET IN FRONT OF ANOTHER CAR IN THE FAST LANE BEHIND ME. IMMEDIATELY AS I WAS GETTING CLOSER TO THE TRUCK TO PASS IT - SUDDENLY MY CAR PUT ON ITS BRAKES TO AVOID A COLLISION WITH THE TRUCK SINCE THE SYSTEM WAS SENSING THE TRUCK WAS IN MY PATH ON THE SWEEPING LEFT TURN. FORTUNATELY THE CAR BEHIND ME IN THE FAST LANE WITH ME DID NOT REAR END ME. THIS IS JUST ONE OF MANY TIMES MY CAR MISTAKES OTHER CARS AS A DANGER AND WILL BRAKE. IF I PULL IN BEHIND A CAR THAT JUST PASSED ME - BRAKE! IF A CAR IS TURNING RIGHT AND SLOWS DOWN AT THE INTERSECTION AND IS MAKING THE TURN - EVEN THOUGH I WOULD NEVER HIT IT -BRAKE! THIS IS SUPPOSED TO BE A SAFETY ITEM - BUT SO FAR JUST IS SO OVERCAUTIOUS I AM SURPRISED I HAVE NOT BEEN REAR ENDED SO FAR. I DO NOT USE THE CRUISE CONTROL AS MUCH AS I DID WHEN I FIRST GOT THE CAR. I TURN IT OFF NOW TO AVOID SITUATIONS THAT CAUSE THE INADVERTENT BRAKING.
