2009 Mercury Mariner. The rear end of the vehicle makes a squealing noise upon acceleration I took the car back to the Ford dealership in hillsdale. The vehicle was in the shop 12/9/2009 through 12/16/2009. Unable to fix the noise, Ford Motor Company had them tear down the transmission and replace the drive chain. When I picked up the car I was told that the noise was still there and that Ford engineering said it should not be a problem. The noise was still consistent and has grown increasingly louder. Since this initial complaint I have received a recall notice for the transmission solenoid regulator valve. The vehicle has been accelerating when it shouldn't and not accelerating when it should, like when merging into traffic when the transmission would not perform properly.
