Engine Funny Noise problems of the 2010 Ford Escape

Right after the warranty went out the vehicle starting slamming from 1st into 2nd upon acceleration. The idle is very rough and quite loud, the engine makes a funny noise and I take extremely good care of my vehicle, getting all of the scheduled oil changes on time, replacing the air filter, etc. I also explained to them that the vehicle wasn't idling properly and that the engine used to be quiet. The windshield is extremely thin as well, a small pebble hit my windshield causing a 8 inch crack in a matter of minutes to where it was beyond getting it fixed. Then liftgate started giving me problems. When you press the button, it would make the sound, but sometimes open, then on may 17, 2013 it just quit working all together. On may 18, 2013, I took it to reynolds Ford for a scheduled oil change right before a trip to mexico and upon telling them about it, they wanted $250 just to look at it before parts and labor. Now, the rear blinker doesn't work and you can't replace it due to the fact that you can't get the liftgate to open in order to remove the rear taillight assembly. So, when you are trying to make a left turn, vehicles behind you don't know you are turning and almost hit you (safety hazard). You also can't change a flat tire since you can get to the jack, which is in the rear compartment accessed through the liftgate. This is a serious problem as there is no manual release for the hatch to get it open period, once the latch doesn't work, it just doesn't work.

While engine is underload reproduced by pressing both gas and brakes simultaenously; at acceleration and between 30-40 mph the engine makes an audible thumping noise. Ford has been unable to correct this problem and calls it normal. They indicated I should drive more aggresively (faster and forcing the engine to shift gears) in order to avoid this condition. This is dangerous and irresponsible advice that may lead to an accident. The condition may lead to engine failure.
