ENGINE 'DIED' (VEHICLE LOST ALL POWER) WHILE TRAVELING AT HIGHWAY SPEED. I HAD TO PULL VEHICLE OVER ON SIDE OF THE ROAD WITH NO POWER ASSISTANCE STEERING OR BRAKING.

I WAS TOLD THAT MY FAILED CAMSHAFT SENSOR IS DIFFERENT AND IS NOT COVERED BY THE MANUFACTURER, EVEN THOUGH IT PRODUCES THE SAME SYMPTOM/RESULT AS A FAILED CR…

TRANSMISSION MODEL 722.9 FAILURE WHILE DRIVING. CREATES AN EXTREMELY DANGEROUS SITUATION THAT COULD LEAD TO FATAL ACCIDENTS. TRANSMISSION COMPLETELY DISENGAGES BRINGING CAR TO STAND STILL, OR IT DOWNSHIFTS WITHOUT ANY WARNINGS AT HIGH SPEED. FEELS LIKE THE ENTIRE TRANSMISSION IS DROPPING OFF THE CAR. MY CAR HAD ONLY 45K MILES ON IT WHEN IT FIRST EXHIBITED THIS PROBLEM. NOW IT COST MORE THAN RETAIL VALUE OF THE CAR TO REPLACE THIS TRANSMISSION.
