Just got a f350 2011 6.7
What is the buzzing noise when I open the doors? It will also buzz when its just sitting there. I was in garage about 40 mins after i drove it and I heard it.
Second I was parked in my driveway which is an incline slightly. I tried to put it in gear to pull in garage and it acted like it didn't want to go. I could hear a very slight grind when I would gas it. I didn't gas hard just shifted in nuetral and rolled back some then put in gear and it seemed to go.
Third sometimes when i start to press on gas slowly it acts like it is struggling for fuel or something. Happens usually first couple minutes of driving.
Any help or ideas? Has anyone heard any problems?
Bought truck new and it had 120 miles on it which pissed me off but thats the color and everything I wanted.

 

oh yeah. Also when I shut off the truck there is a real high pitch noise for about 15 to 20 seconds after I shut it off. I have seen the complaint on other forums just haven't seen any responds.
