Owner report 10340338 · 2010-06-28 (June 28, 2010)

IN A HARD-BRAKING SITUATION, BRAKES FAILED - NO DISCERNIBLE DECELERATION AT ALL, PUSHING HARDER THAN I'VE EVER HAD TO BEFORE. THIS MADE FOR REAR-ENDING THE GUY AHEAD OF ME. FORENSICS INVESTIGATOR W/ MECH FOUND ODB DTCS SHOWED ONLY P0A8D AND B1318 - ONE OF WHICH SHOWS A LOW VOLTAGE TO ABS SYSTEM. MULTIPLE REPORTS OF THIS WITH ESCAPE HYBRID OWNERS.

Owner report 10306742 · 2010-02-05 (February 5, 2010)

I HAVE A 2008 MERCURY MARINER HYBRID 4 WHEEL DRIVE. ON OCCASION THE STEERING WILL LOOSE POWER ASSIST WHILE TURNING. THE LOSS OF POWER LASTS FOR A FEW SECONDS BEFORE THE POWER ASSIST RETURNS. THIS PROBLEM IS DANGEROUS AS I HAVE TO COMPENSATE FOR THE LOSS OF STEERING ASSIST BY TURNING THE STEERING WHEEL HARDER, THEN WHEN THE POWER ASSIST RETURNS THE VEHICLE TURNS MORE THAN I WANT BECAUSE THE WHEEL IS EASY TO TURN AS I AM APPLYING A LOT OF PRESSURE TO THE STEERING WHEEL. THE DEALER AND FORD HAS NOT BEEN ABLE TO DETERMINE THE PROBLEM OR SUGGEST…
