My vehicle started leaking fluorescent oil from behind the radiator. Apparently, it's the condenser. I have been told that the radiator lines run through the same system, and that if it is not repaired my transmission will eventually fail. This failure was explained to be the transmission locking up, and they said if I'm going over about 30 mph it will be very dangerous. I am about 2,000 miles out of warranty, and the emails I have sent to Ford only get a response that they will be happy to take my money and fix it. Within a few months of buying it, the intake manifold had to be removed to repair something. Then, a transmission solenoid. Then, it was shifting funny -because it had very little fluid-noone could explain why. The vibration in the gas pedal at 42 mph "could not be verified. " the manufacturer was apparently out of satellite receivers, so they just didn't put one in. . . The lack of quality overall proves that the length of the warranty is to prevent them from costly fixes. . . And my "long term investment " makes me feel like I'm putting mine and my family's health at risk by driving it. I spent every dime I saved in iraq on this pos because I knew I wouldn't be able to afford another vehicle until I'm out of medical school.

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.
