NO MORE POWER STEERING, NO POWER BRAKES, WHILE COASTING THROUGH A NEIGHBORHOOD. I PUT THE CAR IN NEUTRAL, TURNED THE KEY OFF, BACK ON AGAIN, AND PUT THE CAR BACK IN DRIVE. THAT FIXED THE PROBLEM. THIS IS VERY SCARY AND DANGEROUS!! THIS IS THE THIRD TIME IT HAS HAPPENED TO ME. I AM AFRAID TO USE THE CRUISE CONTROL ON MY CAR NOW :( *TR

THE SECOND TIME I PUT IT IN NEUTRAL AND RESTARTED IT WHILE MOVING. I AM AFRAID TO USE THE CRUISE CONTROL NOW - IF THERE HAD BEEN ONCOMING TRAFFIC WE WOULD'VE HAD A HEAD-ON COLLISION AS I WAS ON A CORNER AND WENT INTO THE OTHER LANE. WHEN THE ENGINE SHUTS OFF, THE POWER STEERING IS GONE LEAVING IT VERY DIFFICULT TO TURN. *TR

THERE IS A CRACK IN THE LIFT GATE WHICH OCCURRED OVER TIME FOR NO APPARENT REASON AS THERE WAS NO ACCIDENT OR COLLISION OF ANY KIND WITH MY MOUNTAINEER.

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.
