I recently bought a used f350 from Pearson. I was told that the vehicle had been through the shop and had no problems. When I test drove the truck there was no faulty engine lights or anything. Once I signed papers and drove off the lot. A TBC fault happened on the dash. I looked it up and figured that this isn't an issue to be concerned about. 3 days later an engine check light came on while 90 miles away from home. I had to drive it to get back home for it was 9PM and I couldn't just stop in the middle of nowhere on a Sunday. I checked all fluids the next morning and cleaned the battery terminals, thinking that this might be the problem. 3 days later the check engine light came on again. The next morning I started the truck up to find it was blowing white smoke. I didn't drive the truck any more. I went to Pearson Ford and all the would offer me was a free diagnosis. This in my opinion is BS. I know that I bought as an as is vehicle, but after doing more research about the TBC FAULT this can be reset by Fords IDS scanner. I honestly think that I was bamboozled. I went to what I thought was a reputable dealer and ended up paying over a grand to repair this truck. (That's only parts, not all the time that it took me to do it). I am writing this as I am agitated. When talking with the salesman, he assured me that the truck had been through the shop and nothing was wrong. Their shop didn't even take the time to clean the battery terminals or change the oil. Which was disgusting. When you pay $14000. + you should expect something to last more than 8 days.
