I took my 2012 f150 in for an inspection because I was concerned about the way the transmission was shifting. I originally was going in for a level 1 inspection, but the service writer suggested I should probably go for a level 3 after I listed all the different issues the vehicle was having. $350 later I realized I had traded my previous vehicle for a lemon, but called and thankfully I was able to reverse that trade. Now, I realized the vehicle was in poor condition when I brought it in, but what I didn't expect was for the coolant hose to be left completely undone from the reservoir when I got it back. I drove the vehicle halfway to where I was trading it back when the ECU engaged cylinder head protection and the truck started shaking violently. I was able to reconnect it and add a gallon of premixed coolant at the gas station I pulled in thankfully. I highly recommend you look under your hood when picking your vehicle up from this place.
