Open the full vehicle complaint log (all categories)Complete loss of brakes while driving. thankfully it was very soon after leaving home. Brake pedal was extremely stiff, and the brakes would not work. Upon investigation it was found the camshaft coupler screw broke inside the camshaft and the vacuume pump had failed. This is an extremely dangerous design due to 0 warning lights on dash, and no prior warnings. Just a complete loss of brakes abruptly.
I WAS DRIVING IN THE LEFT LANE, OF A MULTI-LANE INTERSTATE. I HAD THE CRUISE CONTROL ON. THERE WAS A STANDARD-SIZED DUMP TRUCK IN THE LANE NEXT TO MINE, UP AHEAD. THE ROAD WAS STRAIGHT, WITH ONLY A SLIGHT INCLINE. THERE WERE NO VEHICLES IN FRONT OF ME FOR AT LEAST A HALF OF A MILE OR MORE, AND ALL TRAFFIC WAS RUNNING SMOOTHLY. AS I PASSED THE TRUCK, THE CAR SUDDENLY JAMMED ON THE BRAKES. I'M NOT SURE, BUT I EITHER INSTINCTIVELY HIT CANCEL ON THE CRUISE CONTROL, OR I PUT MY FOOT ON THE BRAKE. EITHER WAY, IT ARRESTED THE HARD BRAKING SITUATION. I NOTICED THAT THE SUN WAS AT MY 2 O'CLOCK POSITION, AND AS I BEGAN TO PASS THE DUMP TRUCK, ITS' SHADOW WAS THROWN ONTO MY VEHICLE. I'M SURMISING THAT PERHAPS THE COMPUTER THOUGHT THE SHADOW WAS AN OBJECT AND TOOK ACTION. REGARDLESS, THIS WAS AN ENORMOUS SAFETY ISSUE. HAD THERE BEEN A VEHICLE CLOSE BEHIND ME, IT WOULD HAVE CERTAINLY RESULTED IN A MASSIVE ACCIDENT. IF THIS CAR CONTAINS AN EVENT RECORDER, I WOULD BE HAPPY FOR YOU OR LINCOLN TO DOWNLOAD THE DATA. I HAVE LOST ALL CONFIDENCE IN THE "SAFETY" FEATURES OF THIS CAR, PARTICULARLY THE ACTIVE BRAKING SYSTEM / COLLISION AVOIDANCE SYSTEM. I HAVE NOTICED IN THE PAST, THAT IT WILL JAM ON THE BRAKES AS IT'S COMING AROUND A CURVE ON A MULTI LANE ROAD, WHEN IT DOESN'T "SEE" THAT THE CAR AHEAD OF ME, IS ACTUALLY IN ANOTHER LANE. I HAD LEARNED TO ANTICIPATE THAT BEHAVIOR, BUT NOT THE BEHAVIOR EXPERIENCED YESTERDAY, WITH THE ALL-OUT PANIC BRAKE. IF THERE IS ANYTHING I CAN DO TO HELP INVESTIGATE THIS INCIDENT, PLEASE CONTACT ME ASAP.
