Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2015 F350 6.7 diesel with 46,000 miles that is down because hpop is defective and spreading medal through system. Ford has inspected and said it is because of water in fuel, even though no warning lights or codes are available. Ford pulled sensors out of engine and rejected repair because of tarnish on sensors. The only codes were for (low fuel pressure & reduced power). No other codes. Initial inspection revealed about 3/4 inch of water in water separator but no light or code. The warnings occurred when truck was started and it ran about 100 ft before being shutdown and towed to dealership. This appears to be a common problem since Ford offers a repair kit for this issue. Total cost of repair is between $9500,00 & $12,500 dollars and this on a truck which is still under warranty that Ford will not honor. The truck wasn't a year old until May 2016 and has been down for over four months because Ford will not repair. This is the Bosch C4 series pump.

I have a F350 2015 vehicle, having an engine knock noise and hesitation problems right after the engine knocks. I have experienced these concerns five times. The dealership is saying is a characteristic of the vehicle due to California regulations. There is a tsb to the concern that I am having, but I don't think my vehicle should have the heads rebuilt since I just purchased it back in Dec 2015. What is the state doing to have this concern resolve" I brought it in two days ago to the dealership and since after the 4th time of the engine knocked the check engine light came on they ended up replacing a sensor. I picked up the vehicle from the dealership yesterday and on my way home, the engine knocks to happen again. I am waiting on fmc to call me and tell me what they are going to do now. The vehicle has two other problems a windshield noise at 60 to 70 miles per hour on windy days. They resealed the windshield the problem exists. They are telling me, that unless they duplicate the issue, they can't do anything. I showed them a video that I recorded during the concern happening, but they are ignoring it. I showed them a video that someone else posted on you tube same concern. However, since they cannot duplicate they cannot do anything that is their answer. I also have a problem of the transmission, harsh shift as slow speeds same thing can't duplicate is what the work order from the dealership states. What can I do to have this vehicle looked at for the concerns I am having" it has been in the dealership four times since I bought it.

During regeneration of the diesel particulate filter the truck loses power and operates roughly. This last occurred as I was merging into traffic on the highway during slick road conditions. This could have very easily resulted in loss of traction and/or collision as I was unable to accelerate to speed.

Engine stopped once in the road pulling a 40 ft.R.V..intermintley severe loss of power and trying to overheat. Comeing down a 7200 ft. Mountain I lost the R.V. brakes, engine brakes & the tow haul mode (to help slow down) all I had was the truck brakes going around 80 M.P.H. by the time I got stopped all 4 wheels were smokeing cooking the related parts, rotors, brake pads, calipers, wheel bearings in my opinion.later in a town going slow and stopping the brakes pulled violently to the right, a few more traffic lights then violently to the left. Failing to clean the diesel exhaust filter as needed. Sometimes the wipers come on one time when starting the engine. 3 attemps to fix the engine problems and in my mind it is not fixed yet, most of these problems happened at higher altitudes. All this information should be in the trucks black box, since I could have gotten killed twice I have not let the dealer have the truck again as it is running O.K. now and I have ordered a new truck because I am afraid of this truck. The dates are approximate, the dealers and I have a copy of the repair attemps. I was on the same roads two years ago with a 2011 F-250 same engine and a heaver load and did not have any problems.
