What owners say
The car takes off as if it doesn't want to allow shift change. It automatically changes on it's on. Transmission starting to slip.
Heard a popping sound near the center front of the SUV. Thereafter noticed some grinding going on when the SUV was accelerating. Took it a dealer to have look at the brakes. Turned out to be the front axle assembly broke and got metal filings in the differential causing the transmission to slip. Repair cost thirty-three hundred dollars. Replaced the differential and front axle assembly.
On 04-06-2009 at 10:30 am I was driving south on md rt. 4 . The transmission then slipped out of gear while decelerating. Followed by a loud grinding noise, my RPM's raced and then slammed into gear almost causing a serious accident.
