Hello all,
Just bought a 2012 F350 6.7 4x4 in the beginning of March. After about 500 miles the "Exhaust Fluid System Fault - In 50 miles, speed limited to 50 mph" message displayed. So first thing that occured to me was maybe it was low on DEF, so I added approximate 1.5 gallons as it had some already in there. I also called the dealer who said "well it just needs to be driven on the highway" hmmm, that sounded weird but I did it anyways. After that I started the truck and the message was gone. I thought that fixed it. - Nope, at about 1480 miles I got the same error message again.
So after getting the message again I just kept driving and the message went away. I thought ok. Yeah right! Now in the past few weeks I have been noticing that the truck almost wants to stall and begins to shudder when going over a slight incline and shifting from 5th to 6th at about 45mph. When I accelerate it makes a knocking noise. If I let off the accelerator, let it slow down, it downshifts into 5th and I then accelerate and it goes away.
And today... I decided to go for a nice ride. After about 10 minutes of driving I get the ole "Exhaust Fluid System Fault" error again. Crap! Again, I keep driving and after another 15min - I get that shutter and knocking noise. Now I am thinking "WTF". anyway I drove until the the truck displayed "Speed limited to 50mph on next restart. I just kept driving and the error message mysteriously disappered again.
Oh and I did call the dealer that I purchased the truck from. They cannot see it until Tues.... Crap! The dealer did mention that TSB for the RECALL 12B33 had already been performed. I had him print me a copy.
Anyone else have any of these problems?
Sorry for being so verbose...
