MY MOUNTAINEER STALLS WITHOUT WARNING WHILE GOING ABOUT 35 MPH BUT AFTER A FEW MINUTES CAN RESTART. IT HAS DONE THIS 4 TIMES OVER THE LAST 3 OR SO MONTHS. IN ADDITION TWICE IT WOULD NOT START (IT HAD BEEN ABOUT 30 MINUTES SINCE I DROVE IT) AND IT HAD TO BE JUMPED. I REPLACED THE BATTERY THINKING THAT WAS THE PROBLEM BUT IT PERSISTS. I BROUGHT IT TO A REGULAR GARAGE ONCE, WHO KEPT IT FOR A DAY AND FOUND NOTHING WRONG. I THEN BROUGHT IT TO A MERCURY DEALER WHO KEPT IT FOR 2 DAYS BUT FOUND NO CODES OR PROBLEMS. IT JUST STALLED AGAIN TWO NIGHTS AGO WHILE I WAS DRIVING 35 MPH WITHOUT AND RESTARTED A FEW MINUTES LATER. THE DEALER HAD IT FOR A DAY BUT AGAIN FOUND NO CODES OR PROBLEMS. SO FAR I JUST PUT IN A NEW BATTERY AND THEY CHANGED THE OIL AND FILTER. *TR

EA09013 · Vehicle Rollaway Allegations

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.
