2 Transmission Failure problem

Failure Date: 12/23/2011

On Feb 2010, I signed a 3-yr lease on a 2010 Mercury Mariner. On Dec 23, 2011, after 8hrs of driving, on the way to my relatives, the vehicle started jerking. With 22,250 miles on the vehicle, my transmission failed; very harsh engagements, vehicle jerks hard between gears, looses power and pops forward when driving steady speed and when approaching an intersection to stop or turn. Safety concerns due to unknown if power failure will occur when there is oncoming traffic or if vehicle will pop me into oncoming traffic or hit someone ahead of me in traffic. Transmission issue also causes poor gas mileage. On 12/24/11, I took it to a nearby Ford dealership and they have had my truck going on two weeks and they are just repairing the transmission. Since I leased this through Ford motor credit, I contacted them last night in hopes that they will at least pro-rate my lease for the month. To no avail, they said they can't. The dealership said that there is no recall for this problem but it seems like I am not the only one experiencing these issues. What can I do?.

3 Transmission Failure problem

Failure Date: 10/16/2010

I purchased 2010 Mercury Mariner at the end of may 2010, approximately 21 weeks after purchase date my transmission failed; very harsh engagements, vehicle jerks hard between gears, looses power and pops forward when driving steady speed and when approaching an intersection to stop or turn. Safety concerns due to unknown if power failure will occur when there is oncoming traffic or if vehicle will pop me into oncoming traffic or hit someone ahead of me in traffic. Transmission issue also causes poor gas mileage. Ford dealership replaced transmission in 10/16/10 (13 days with dealership) and stated vehicle issues were corrected. I returned vehicle to dealership for continued transmission safety issues (same as noted above) on 12/06/10 (4 days with dealership), again on 1/11/11 (16 days with dealership) after I had submitted 30 demand letter on 12/15/10 to repair or repurchase vehicle and dealership advised each time transmission repair completed. Yet each time transmission issues/concerns still remain. Dealership service manager drove vehicle and agreed there are transmission issues/concerns. Ford customer relations advised a TSB would be issued prior to end of June 2011 that would correct transmission and offered an extended power train warranty of 60 months or 100,000 miles. I have sent emails to Ford customer relations inquiring on the TSB on 6/27/11, 6/29/11 and 7/7/11, no response received. No TSB to date. Ford motor company is not standing behind their vehicle production nor the consumer that purchased this vehicle.
