Hey everyone, new here obviously, looking for some info not exclusive to Tremors but just overall reliability on '17+ Super Duty. I'm talking about the ones that have put 200k+ on them here. I put a lot of miles on and I'd really like to know from anyone else who has done this with late model 6.7 powerstroke/Super Duty trucks what kind of issues you've seen and at what mileage. I've been driving my '09 Ram 2500/6.7 for a while and want to see how a super duty would compare in upkeep. Not talking about oil changes fuel filters or scheduled maintenance here. I'm looking more for things like fan clutch, water pump, hvac actuators, fuel pumps, major mechanical engjne/trans/driveline or suspension issues. I'm looking at potentially a 6.7 PSD truck because after owning a diesel so long I could never go back to gas. I'm addicted to the power and efficiency of diesel. If you're a gas truck owner feel free to comment as well. Help is much appreciated here. I've been happy with my Dodge for a long time and had a few really bad experiences with older Fords but the new trucks have me considering giving them another shot, I just want to know what I'm getting myself into first to compare with my firsthand dodge ownership experience. Please don't make this a dodge vs ford debate that's not what I'm looking for. Just tell me what issues you've had if any and at what mileage. Also tell me how many miles you personally put on the truck please. I don't need someone who's bought it with 225k but only put on 1500 miles telling me they've never had any issues because that info is obviously not very helpful.

so i can only give you suggestions go check out this video he is a hotshot drivers so drives like crazy and uses alot of 2020 6.7 F350 dually to hotshot he has been through 3 of them and already got one to 75k miles in a few months

he had a few dodges but he has nothing but good things about the Ford and had a few problems with his dodges but to be far the dodges are a little olders and have more miles but he is doing nothing but towing and that is the ultimate torture test.... check out his channel i really watch to see how the fords are doing

Guess I am going to find out first hand. I don't have the miles but I choose the Tremor because, I felt Ford would stand behind it and they have a lot evolution in their products to insure long lasting reliability. I got away from the Cummins trucks because they did not hold up over the long haul. Rusted out, tranny problems, wiring problems, front end, brakes, cooling lines to transmission. The axles were great and of course the Cummins.
There are more Ford dealerships in my area and areas that I travel to so I feel confident if there is an issue I can get it resolved.

Pretty much anything holds up for 75k these days though. That's why I'm looking for high mileage. You really don't need to do anything serious to any of the current diesels until they start getting over 100k.

Pretty much all the modern diesels are going to have the same potential problems. The most common are the emissions systems and fuel system. The scary thing about a fuel system failure is that it can contaminate the whole fuel system if the high pressure pump fails, which can be thousands to replace all the components. Typically warranty will cover it, but on some occasions if bad fuel is determined to be the cause, it is not covered.

This is the actual reason you need to use a high quality Fuel Additive ! Fuel is the key to any make diesel and it needs to be conditioned. Adding this will lubricate the pump and keep the fuel system clean. The high mileage diesels get there by using good fuel and good fuel system maintenance.

I would say emissions, fuel pump/injectors, turbo, and sensors would be the biggest concerns. The downside, is none of it is cheap or easy to fix when out of warranty, any one component could be thousands to repair, a turbo I would bet over $5k to replace. If I had a diesel I would probably opt for the longest warranty I could get and probably consider replacing it once out of warranty. I know people say just to delete all the emissions but the only thing I would warn is that unless you know a good private mechanic or have a very good relationship with the dealer, some might not work on a deleted diesel. I know personally of a few situations that a repair on equipment was denied because all the emissions were removed. In one case it was added back on before the repair/diagnosis would even be allowed.

One of the reasons I'm considering a Ford even though I've had a few bad experiences with them in the past is because I have a very good relationship with my local Ford dealer. I don't plan to delete, I was a Dodge mechanic for years but I'm out of it now and only work on my own truck when necessary. My hope is that I can trust my Ford dealer to do a good job on repairs if I buy a Ford so I don't have to roll around in the driveway every time something goes wrong. My Dodge has been good but I love the looks of the F250 Sport/Tremor combo. I owned an F350 OBS that I really liked as well even though it was constantly broken. The new F250/Tremor reminds me a lot of it. I just don't want the new one to be a money pit or in the shop constantly. I put 30k+ on a year so it's not like I'm hot shotting with it but it's definitely more than average. When you're putting 100k on every three years it always feels like "didn't I just fix that?" The Cummins is friggin bulletproof so I've had no real issues. It's all the little stuff on the truck that has been an issue. Nothing that leaves me stranded ever just a steady stream of minor annoyances. Wondering if I can hope for as good or better ownership experience of a current model Ford. I know they have made quite a few improvements over the years...

I had 150+k on my 2015 that I traded for the Tremor. Only issues I had were a charge hose that failed early on, replaced under warranty, and the DEF pump? (I believe .. something DEF related for sure). Otherwise I just kept up with the regular service and maintenance intervals and it ran like a top.

It finally came down to the decision to either a) keep the truck and run it into the ground, or b) trade it while there was a decent trade value. I opted for B and piked the Tremor up.

Pretty much where I'm at as well. Although my trade value isn't great I can sell it outright for at least some reasonable amount because diesel trucks are highly desirable in my area. If I go much over the mileage I'm at though the value will plummet so I'm considering going with the Tremor. The new "Ram" is not the most stylish IMO and if I'm spending 60-80k on a truck it had better look badass.

I couldnt agree more , back when I had 6.0 powerstroke every fill up I put stanadyne in it just part of the ritual. when and if I get back into a 6.7 its going to be the same!
