The sound or drop in engine rpms doesn't happen on idle only under load. The noise sounds like a muffled grinding, maybe, but when it on the cars jerks really bad and revs drop low. If I release the gas pedal it stops and the car just cruises. I changed the spark plugged and the air intake, new air filter and ran injector cleaner in the fuel system. The oil level is good in transmission and engine. A mechanic suggested a misfire but there is no check engine light on, pluss it doesn't happen on idle. So far it seems to do it soon after starting to drive the car. I started the engine and let it worm up, drive in my subdivision for aprox 3 minutes and the noise and shaking was very bad but then subsided. It will still do it but not as bad while driving to work. One option is to drive it until it breaks down completely but I would prefer not to waste my money on a tow truck or unneeded repairs because this was not treated in time. Any advice is greatly appreciated. By the way, a friend connected a computer to the engine to see if there are any codes but none showed up.

My Edge has keyless entry and start. Sometimes when I get in the car and start it up, a warning comes on saying "No Key Detected." The car starts, but why does it tell me this?

When I am driving on the highway I turn off the Brake Assist setting and Collision Warning because I don't like it. However, I notice when I drive above 55mph, the car will randomly brake, even with no other cars around. It will slam on the brakes, and it will even send a warning message saying, "Collision Warning Not Available." Why is it doing this? And what can be done?
