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

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.
