PURCHASED A NEW 2005 MERCURY MOUNTAINEER IN 7/31/2005 THE FIRST TIME THE CAR ACCELERATED WHEN THE BRAKES WERE APPLIED AND THE CAR HAD TO BE PUT IN NEUTRAL TO STOP. THE DEALER REPORTED THAT THERE WERE NO KNOWN FIXES FOR THIS PROBLEM AT THIS TIME. THE SECOND TIME WHILE PULLING INTO MY DRIVEWAY WHEN THE BRAKES WERE APPLIED THE CAR ACCELERATED AND CRASH INTO MY GARAGE DOOR. THIS TIME THE DEALER BLAMED MY WIFE AND SAID SHE MUST HAVE PRESSED THE GAS AND BRAKE PEDDLES AT THE SAME TIME. THE CAR SUSTAINED FRONT END BODY DAMAGE AND MY GARAGE DOOR NEEDS TO BE REPLACED. THE CAR HAS BEEN AT THE DEALER SINCE THE ACCIDENT HAPPENED AND WE ARE STILL WAITING TO FIND OUT WHAT IS FORD'S DETERMINATION OF THIS ISSUE AND WHAT THEY WILL DO TO GET US OUT OF THIS CAR AND INTO SOMETHING ELSE. *NM

2005 - MERCURY MOUNTAINEER. THIS VEHICLE HAS WHAT I BELIEVE IS A BRAKING DESIGN FLAW. I HAVE BEE COMPLAINING ABOUT THIS BRAKE IN THIS VEHICLE FORM DAY ONE AS WE FIRST THOUGHT THAT THE BRAKE ROTORS HAD TIRE DRESSING ON THEM. THIS WAS NOT THE CASE. IT NOW APPEARS THAT THE BRAKE PEDAL IS DESIGNED FOR THE SHORTER PERSONS, AROUND 5 FT, 2 IN. THE BRAKE PEDAL WITH A PERSON OF THIS SIZE WOULD SIMPLY PUSH THE BRAKE PEDAL ALMOST STRAIGHT DOWN DOWNWARD TOWARDS THE GROUND. A PERSON OVER 6 FT LIKE MYSELF (6 FT, 6IN), CANNOT PUSH THIS BRAKE PEDAL DOWNWARD IN THE SAME FASHION AS THE SHORTER PERSON. THE TALLER PERSON LIKE MYSELF PUSHES THE BRAKE PEDAL TOWARDS THE FIREWALL. THIS BRAKING ENERGY IS NOT TRANSLATED PROPERLY TO THE BRAKE PEDAL, CAUSING FOLLOWING: THE VEHICLES BRAKES WILL NOT TO STOP THE VEHICLE IN A TIMELY MANNER. THE VEHICLES BRAKES APPEAR DRIVE AS IF THE BRAKE ROTATES ARE GLAZED. THE DRIVER OF THE VEHICLE LEG WHILE DRIVING IN CITY TRAFFIC WILL FATIGUE QUITE EASILY. THIS MAKES IT EVEN HARD TO STOP THE VEHICLE AFTER YOU HAVE DRIVEN IT FOR A TIME. PLEASE NOTE THAT I HAVE CONTACTED MY DEAL WHERE I PURCHASED THE VEHICLE AND MOTOR COMPANY. THEY ARE ALL AGREE, THAT THERE IS A DIFFERENCE BETWEEN DRIVE SIZES IN THIS VEHICLE. THIS IS NOT IN DISPUTE; THE FIX OR CORRECTIVE ACTION IS IN DISPUTE. FORD AND THE DEALER WANT FOR ME FOR ME TO PAY OVER $3,000.00 IN ORDER TO UPGRADE THE SAME VEHICLE EXCEPT THIS ONE WOULD HAS THE $120.00 ADJUSTABLE PEDAL OPTION. IT APPEARS THAT IS OPTION IT REALLY NEEDED TO BE STANDARD IN ALL VEHICLES OF THIS TYPE. NOTE PER FORD BOOKLETS, THIS ADJUSTABLE PEDAL IS DESIGNED FOR SHORTER FOLKS AND NOT TALLER FOLKS. I AM TRYING TO WORK THIS OUT WITH THE DEALER AS FORD HAD BECOME DEAF TO MY ISSUE. NOTE THERE TAKE IS WILL NOT ASSIST IN ANY WAY. WHAT A GREAT CAR COMPANY.

EA09013 · Vehicle Rollaway Allegations

Opened Aug 18, 2009 · Closed Feb 12, 2013

Status: closed (inferred from source dates) · Power Train:automatic Transmission:gear Position Indication (prndl); Power Train:automatic Transmission:lever And Linkage:column Shift; Steering; Steering:column; Steering:column LOCKING:ANTI-THEFT Device

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.
