OWN A 2005 MERCURY MOUNTAINEER. SINCE I'VE PURCHASED IT I'VE HAD ISSUES WITH THE AIRBAG LIGHT STAYING ON, THE SEATBELTS NOT REGISTERED AS BEING UNDONE AND THE GAS NOT REGISTERING (I FILL IT UP AND IT SAYS THE LAST AMOUNT AND WILL NOT SAY IT'S FULL UNTIL SOMETIMES 2-3 DAYS). I'M MOST CONCERNED ABOUT THE AIRBAGS AND THE SEATBELTS. I SEEN THAT EARLIER MODELS AND 2006 HAVE ISSUES WITH THE AIRBAG NOT DEPLOYING. THE DEALERSHIP HAS REPLACED THE SENSOR 3 TIMES FOR THE AIRBAG AND PUT IN A NEW SEAT BELT SYSTEM ABOUT 15 MOS. AGO. THE DEALERSHIP WILL NOT COVER IT AGAIN AND SAYS I NEED TO PAY FOR IT. THIS HAS BEEN AN ONGOING PROBLEM AND FROM THE WEB RESEARCH, IT'S NOT PROBLEMS THAT MERCURY/FORD IS UNAWARE. THESE ARE SAFETY ISSUES. *TR

TL* - THE CONTACT OWNS A 2005 MERCURY MOUNTAINEER. ON 11/20/06 THE CONTACT'S HEATER ON/OFF SWITCH WOULDN'T ALLOW HER TO TURN THE HEATER OFF. THE CONTACT HAD TO DRIVE WITH THE WINDOWS ROLLED DOWN. THE CONTACT ALSO ATTEMPTED TO TURN THE VEHICLE OFF AND RESTART AND THE FAILURE CONTINUED TO OCCUR. WHILE DRIVING ON 12/18/06 AT 35MPH THE ENGINE STALLED AND THE VEHICLE SHUT OFF. THE WARNING INDICATOR LIGHT READ CHECK ENGINE, LOW PRESSURE PRIOR TO THE FAILURE. THE FAILURE ALSO OCCURRED ON 1/19/07. EACH TIME THE FAILURE OCCURRED THE CONTACT WAS USING THE CRUISE CONTROL. THE VEHICLE HAS BEEN DIAGNOSED AND FOUND THE VEHICLE TO BE OPERATING NORMALLY. THE MECHANIC HAS ALSO DRIVEN THE VEHICLE TO DIAGNOSE IT SINCE THE LAST FAILURE AND HAS EXPERIENCED NO FAILURES. SHE WAS ADVISED THAT THE SERVICE MANAGER WOULD CONTACT HER RE: THE FAILURE AND AFTER THE INITIAL CONTACT, SHE HASN'T RECEIVED ANY CALLS FROM HIM. AFTER 15 TO 20 MINUTES, THE VEHICLE WILL RESTART. THE MOST RECENT INCIDENT ALMOST CAUSED A COLLISION WITH A HEAVY DUTY TRUCK. THE MECHANIC ALSO STATED TO HAVE THE VEHICLE TOWED IF THIS REOCCURS. THE CONTACT DOES NOT WANT TO DRIVE THE VEHICLE DUE TO THE SAFETY RISK INVOLVED. THE CURRENT AND FAILURE MILEAGE WAS 13,000. THE MECHANIC ALSO ASKED IF A LIGHT WAS PRESENT ON THE WINDSHIELD AT THE TIME OF THE FAILURE.

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.
