Differential Unit problems of the 2008 Nissan Pathfinder

Airbag light had come on indicating an issue, but also light and controls on the steering wheel are failing. Vehicle has never been in an accident and there is no reason for this failure. Abs brakes activate randomly without warning preventing and causing the inability to stop. Abs can not be stopped unless I stop and turn off my vehicle and start again. Very dangerous. Cant stop when I need to. During city driving on a dry surface and approaching a stop light my brakes failed several times with the abs activating and making it impossible to stop. Random and without warning. Front differential cracked for no apparent reason and didn't provide any warnings, pinion seal leak appeared less than two years. In addition vehicle was in service for evap system 11 times in the first year without resolve. Gad consumptions was horrible and below any suggested mpg. Tire sensors have never worked and failed to alert low pressure in tires. Tire pressure has been unstable no mater what tires are installed or how many sensors are put on. Stability in steering is sloppy when going over any kind of bump in the road. Unstable when driving. Speed can cause problems when driving curves. Rollovers are definitely possible without much speed when on ramps and curves. Use extreme caution.

I am the one owner of this vehicle which I purchased new in quincy, massachusetts in 2008. I began to sense a clunk or slippage in my transmission about two weeks before the incident. I immediately took the car to an oil change place and had my transmission and differential fluids replaced. Cost $150. Attendent noted magnetic plug had metal shavings and some discoloration in transmission fluid but nothing conclusive to work on. Approx two weeks later while driving up a grade, I experienced a serious "clunk" and immediately pulled into the next service station I could find. I was 100 miles from home. After leaving the car for diagnostic work, I went online to find other similar complaints concerning radiator coolant leaking into the transmission and causing catastrophic failure with no warning. I called the mechanic to report what I had found and asked him to check this condition first. He reported back that this is exactly what happened and I may have caught the defect in time to save the transmission. The mechanic worked on the car for two days to fix the problem. Cost $1100. I have put about 300 miles on the car as of this writing and I now have only an occasional/minor "clunk. " I believe this is clearly a defective Nissan part and note that other people are finding Nissan uncooperative in taking responsibility for this defect. I have receipts for my work done and will provide them if needed. Sincerely kevin meagher.
