In cold weather my gas pedal sticks. Even after I have started my car and let run for 10-15 minutes. When I get in, reverse to forward position and try to accelerate- the gas pedal sticks. I have to slam on it for about 2 minutes before it actually works. This has happened while driving as well, not just the initial start. It definitely happens more in cold weather. What can I do? after research this sounds like it's a common problem with 2008 Mercury Mariners. I believe it's definitely a safety issue.
Without warning the gas pedal sticks, will not function. This happens intermittently and seems to disappear when the car warms up, but also has happened when the car is warm. Very dangerous when trying to accelerate or just drive normally. This seems to be a widespread problem with both the Ford escape and the Mercury Mariner. We have been stranded several times. This needs to be fixed by the manufacturer.
