general problems of the 2015 Ford F-350

2015 Ford f350 6. 7 liter diesel turbocharger with only 58,000 miles malfunctioned while accelerating on to freeway without any prior warning indicators or symptoms. Immediately engine acceleration was reduced drastically causing freeway cars to nearly rear end my vehicle and other cars swerving to avoid accident. A message showed up simultaneously while reduced acceleration occured on vehicle’s dash display indicating something to the effect “reducing acceleration” and a yellow check engine icon lit up on dash display. I limped the vehicle to the side of freeway and shut engine off. Upon restarting engine discovered engine and turbo operated properly and was able to drive vehicle to a non-Ford service center to be repaired. The technician could not find anything wrong with the operation of the engine-turbocharger and cleared the trouble code. Drove vehical for approximately 500 miles and the same reduced acceleration problem re-occurred while accelerating on to freeway. Pulled vehicle over to safe area, shut engine off, re-started engine, engine and turbocharger operated properly, drove home and then to Ford dealership (check engine icon still lit). Discovered vehicle can not be smog tested with this intermittent problem due to check engine icon. My safety, my passengers safety, and others safety while driving on the freeway were put at high risk. The reduced acceleration problem does reoccur. Ford diagnosed the vehicle problem to be a bad turbo with an estimate of $5,100 dollars for removal and replace with new Ford turbocharger which only has a two year warranty. The repair work is currently in process. I consider this turbocharger to be pre-mature failure and a safety risk! this turbocharger intermittent failure in my opinion should be a mandatory recall and paid 100% by Ford.

This vehicle developed a fuel leak in the area of the top of the engine which resulted in a fire that destroyed the vehicle. I spoke to the Ford motor company and they said that there are no recalls or technical service bulletins regarding this. I just wanted to make you aware of my experience so if anyone else experienced this it may show a pattern. Thank you.

1/4/2022 – traveling to southern ohio in F-350. Engine light came on. Truck info screen showed exhaust fluid system fault – indicating truck would lock to 50 mph within a certain number of miles, then possibly shut down. Finally got in touch with Ford dealership in chillicothe and took truck there. They determined it was a def heater and pump causing the issue, and that it would be covered by Ford as an extended warranty issue. Ford decided our truck was not covered. On 1/11, Ford added a new campaign – 21m01, reductant heater and sender assembly, covering the cost of replacement of these items. We were told we needed to pay the repair and Ford would reimburse. To this date, we have not been reimbursed - in fact have pretty much been ignored. The sensor recalibration they did caused the particulate filter to fail. Ford has said they won't replace, even though service manager has said the filter failed because Ford had them recalibrate the sensor. We could have been stranded 140 miles from home because of this design fault that Ford knows about - but is not being forced to take care of. Our truck has less than 64000 miles on it and was purchased new by me in April 2014. Will you please strongly encourage Ford to stand by this defective equipment they have installed in their vehicles, as their 'customer satisfaction campaigns' do not adequately encourage them to fix these faulty issues. Volkswagen and Audi both stand by their defective equipment.

I was driving out of state (NY) when an alert stated "low fuel pressure) and the vehicle slowed to 5-10 mph while traveling on the interstate. Upon exiting, the vehicle stopped running leaving me and my family stranded. I had it towed to a local shop which informed me the bosch high pressure fuel pump was not delivering the required pressure (/,000 psi). Upon contacting the Ford dealership where the vehicle was purchased, I was informed the vehicle exceeded warranty miles (100,000/129,239) and the cost of the pump was $1,245 with exchange prior to labor charges. In all, Ford dealer wants nearly $5,000 to repair the pump which was poorly designed.

Had vehicle 8 months. Driving on interstate 95 pulling my camper, "low fuel pressure" light came on, pulled over immediately. Saw smoke, then fire. Got out of truck with my dog and called 911. Report attached.

We purchased the vehicle brand new (33 miles). At 65,142 miles (07/09/18) the engine quit running and we pulled to the side of interstate 15 barely off the freeway. It had to be towed to the dealership. At 69,345 miles (12/26/18) the engine blew up while we were traveling at 65 mph on interstate 10 towing a 5th wheel trailer. Just made it to the beginning of the off ramp in indio. Towed to the dealership where a short block engine was put in under warranty. At 80,029 miles (08/14/19) the engine locked up, would not turn over. Dealership put in a long block engine also still under warranty. At 115,000 miles (09/06/23) the engine quit running and we had it towed to the dealership where they stated we needed a new engine (#4). Unfortunately, the engine is not available and is no longer under warranty. It has scared us each time there is an engine failure and do not trust the vehicle to keep us out of harms way. I have all of the service order receipts. Thank you for your time.

When vehicle is going thru regen runs extremely rough shaking and bucking .

At 40 to 50 mph the truck can experience loss of power and severe "shuddering" we have 2 2015's that we purchased last September and both are experience the same issue it's very sporadic seems to happen a few times a week. I'm concerned for the safety of my company as we can be pulling trailers and can not have this type of behavior when on busy roads. Ford knows there is an issue as stated in TSB 16-0041, but they will not attempt to correct it unless their techs see it happen. . I have already had it into the shop and they couldn't see the problem. If you look on the internet it appears to be a problem on quite a few 2015's. . Read more...

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.

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.

The vehicle is a 6. 7 Ford power stroke. During a process called regen, where is cleans the diesel particulate filter, the engine would shake violently. It got worse overtime, to the point it started doing it wile I was merging onto interstate, pulling a piece of equipment (9000lb) on a trailer. It was dangerous with the loss of power. I have since traded it back to dealer as Ford has said it is normal operation.
