HAD WARPED ROTORS WITHIN FIRST 2,000 MILES. FORD WOULD ONLY GROUND ROTORS BUT DEALER REPLACED THEM AT NO CHARGE. I HAVE ALSO EXPERIENCED A LOUD, THUMPING NOISE WHEN I AM MAKING A SHARP TURN TO LEFT OR RIGHT AT A VERY LOW SPEED. ALSO, OFTEN WHEN PUTTING CAR IN REVERSE MANY TIMES THERE IS A LARGE THUMP AND VEHICLE APPEARS TO SHIFT HARD. FINALLY, WHEN STOPPED ON A STEEP HILL, AFTER REMOVING FOOT FROM BRAKE, VEHICLE ROLLS BACKWARDS MANY TIMES. *JB

This investigation is being closed based on several considerations.By the most inclusive counting of all alleged rollaway incidents (i.e., counting all alleged rollaway incidents and assuming a singular failure mechanism), the incident rate is low, however during EA09-013, ODI identified a number of different failure mechanisms in 180 incidents related to the alleged defect.The highest rate for any particular failure mechanism, the failure of the Automatic Transmission Parking System, was 4.4/100K.The next-highest failure rate was for the BSI System, at 3.4/100K.For all identified failure mechanisms there has been a drastically declining trend including very few incidents occurring in recent years.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.For additional information regarding this investigation, see the complete closing resume in the document file for EA09-013. The ODI reports cited above can be reviewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification (ODI) numbers:10168454, 10279630, 10280078.
