That is the kicker. I tend to keep my vehicles for a while outside of warranty. If something goes wrong on a gasser, you're looking at a few hundred or a grand to fix it. If something goes wrong on a diesel, you're looking at 2, 3, 5, 7k to get it fixed.

 

Seems I've seen a lot of repairs (fuel pump, etc) which run in the $9-10k range. Oh well, I guess you could always get the Geico MBI insurance...just another bill to pay.


The gas station thing can be true - you need to find a station with pumps parallel to the road. Unfortunately, most are perpendicular. Then again, a lot of the diesel pumps are truck nozzles at a high flow rate. Sucks filling the 26 gallon tank in about 10 seconds with fuel spilling all over the place, lol.

 

So ya'll talking about all of the expensive fixes obviously happening outside of the Powertrain Warranty. Are we talking about folks that drive the truck for a living and are on the road all day or just normal daily driver use? I am still baffled by the feedback about them having problems, I have never heard that before. Granted, they don't get compared to a 7.3, but I have to get my 99' 7.3 fixed every now and then too and it only has 180k on the clock.

 

Just FYI...if you unknowingly get some water in your load of diesel you pump in from the station, and it makes it past the water separator and into the fuel pump, the lack of lubrication can damage or ruin the pump. This sends metal fragments from the pump down the fuel system to the injectors, potentially ruining them as well. Some metal might make it back in the return line to the tank to be "recycled" again.

If this happens within the warranty period, Ford will deny you warranty because it was the "water" which caused the problem, and that is not their fault.

In fact, even if the water never made it out of the separator, but triggered the WIF light, that event is permanently stored in the computer, and could well be the cause of a warranty claim deny down the road.

Rare, but possible. Some users here have had warranty claims denied because of water in the fuel.

 

That does sound like a nightmare. I think I would lose my mind if a dealer tried to charge me a dime within my warranty window. But I have my own 1000 gal diesel and gas Ag. tanks here at home too so hopefully I can dodge that bullet.

 

I use my truck daily for work. When I'm not working I want to be hunting/fishing/camping. I need a truck I can count on 24/7. I cannot afford shop time or "down time" with my truck. Warranty or not, I don't want to be without my truck. I see plenty of newer trucks in the shop at my dealer, there are just not 6.2's. IMO, owning the 6.2, you have the best chance out of all the new trucks today, of never seeing the shop.

 

And people DO sometimes have their head parked in a dark place. Filling a diesel with gasoline, or dumping exhaust fluid in the fuel tank, then think they can start the engine and that maybe it will not hurt!!!!!! These kind of screw ups WILL take the HPFP out! When I had problems with my '15.... said oops, you got a bad unit and has to warranty it, but after the third time, I no longer trusted the truck, and had it at the dealer where I bought it and used my problems as a little leverage to make myself a better deal on the '16.
So, with all that being said, is that not all cases of the fuel pump going out are denied warranty by Ford! If one is diligent when fueling, and adding fluids, doing the proper maintainance, etc. there are way too many of these 6.7's out there running trouble free to make me worry about the dependability of them!
But, to each, their own

 

Good feedback, I agree there are some goofballs out there that are a danger to themselves and will find a way to break something.

I suppose I am such a die-hard diesel guy that it's a no-brainer for me what engine to pick. There was zero thought around it, I just checked the box and moved on.

 

And having had the 6.2, and know about its dependability, I know it is a long shot......but.....the 6.2 is not exactly a cheap engine to rebuild! I did find a couple places online for crate engines, in excess of $6000, and as these engines get more and more miles on them, we WILL eventually start seeing failures on them! Not trying to be a nay sayer, but the idea that one can be rebuilt for a grand is out on these engines!

 

Nobody said it could be rebuilt for a grand.

 

I just don't think a 6.2 will handle my trailer. With the warranty denials on the 6.7, I am thinking of switching to Ram.

 

If you think Ram will be any different on warranty, you're in for a rude awakening.

It's not a persistent problem as some are making it out to be. It's mostly just the potential to have a problem that is causing many to switch to gas. There are so many more expensive things to replace on today's modern diesel engines than there were in the past. The potential for issues is so much greater than with a gasser.

With that being said, the 6.7L has been a tremendous engine with great durability and reliability.

 

Its going to get worse at Ram. My Ram dealer told me they are in the process of implementing a new photo check-in system at all dealers for service/warranty work. He worried what they may turn down in the future if you dont look bone stock. Im not sure how far out the system is but my dealer knows about it.

 

Its possible the 6.2L is not suitable for your trailer. Get the diesel. RAM and GM are not impervious to these same issues - and chances are, they will deny your warranty claim just the same as Ford.

In fairness, if I pump a load of watery diesel into the tank, even though its not my fault, its not Ford's either. There was no defect in material or workmanship. But its hard to go after the fuel dealer.

It is also true not all fuel issues are warranty deny. But you can bet, with the costs involved, Ford will absolutely take fuel samples to try to detect water, and they will scan the computer to see any WIF events.

Running PM22 theoretically helps add lubrication to the fuel, which helps the pump. Draining the water separator monthly also helps catch small water problems early. Some people go so far as to put an additional water separator / fuel filter in-line.

Others simply pump in diesel and never drain anything and never add additives, and never have a problem.

I drove 200 miles straight last night with my 6.7L. For the first time in awhile, it performed a regen in the middle of the trip, on the highway. Normally it does it a mile from my house. Fuel economy (reset for the trip) was up to 21mpg. After the regen, it was down to 16.9. By the end of the trip, it had recovered to 19. Granted, all unloaded. I was very pleased.

The 6.2L will not get that kind of mileage. Maybe 15 on the same trip, unloaded. But I bet with 3k oil changes, that engine will last to 250k or more miles...at that point it will be time for a new truck.

I know many of us buy these trucks because we haul or pull heavy loads...but I actually love taking my truck for a cruise, without load or trailer, down the highway.

 

Well, sir, I mean no disrespect, but then who wrote post #31?? And what was the implication?
While I understand some people hesitation for going to a diesel (I was there for a long time myself) the diesels have come a long way since the advent of the 6.0 and its problems!
Have a great day!
