After driving for a while (roughly a few hours) the Edge does this hard jerk forward that feels like I'm practically being rear ended. It's like a hard pause, before it jerks forward. Then it gradually accelerates. Also, on a few occasions, while pulling out of a parking lot, the Edge did not want to accelerate though I was pressing on the gas. Mind you, I wasn't going fast because I had barely pulled out of the parking stall when this occurred. It barely accelerated then gradually came to a complete stop while in drive. This has also happened while I was exiting the freeway once. I initially thought my battery was the problem, but I had it replaced the following morning. I took it to the dealership and I was told nothing was wrong with it. This was the same response I got when I've taken it to Ford during the term of my warranty. I have noticed that if the "check engine light" isn't on, nor if you're not paid out of pocket, Ford does not recognize a problem. This problem is quite worrisome considering I'd hate to be stranded with my children in an intersection. I live in a very town (los angeles county) where traffic is steady and aggressive so knowing this problem can happen anytime is unsettling, especially because I have been rear ended once for not being able to proceed with traffic at a green light. 2008 Ford Edge, purchase in 2012.
After starting car, vehicle made loud clunk sound when put in reverse. Car would not accelerate without pressing accelerator more than usual and engine revved high. Dash board went blank except for wrench symbol, airbag symbol and odometer had all dashes. Turned car off, waited a few minutes, turned car back on and everything was back to normal, car drove fine. This has happened about 5 times within the past 3 years, several months apart. Have also had to replace rear tail lights multiple times, sometimes within 2 days of replacement. Have taken car to Ford service, but they can't pinpoint problem. Now car is out of warranty. Seems like it could be electrical or sensors. Have read and seen videos of many others with this same problem with this year, make and model. Wish Ford would help owners like ourselves with a recall to fix this, as our loyalty has gone away with frustration. Have just today, 03/27/14 had my car towed to repair shop to check transmission. The dashboard has returned to normal, but loud clunk when shifting and will not accelerate without flooring it.
