6.7 Cummins owners report

Hello everyone. I'm looking into purchasing a newer truck and I really like the current Dodge trucks but I've seen and heard so many problems with the dpf, terrible fuel mileage and emissions b.s. on the 6.7 2007+ that I've kinda kept what I've got. I have driven one 6.7 with the automatic and I really love the power in stock form as well as the exhaust brake. This truck will be left stock and not touched with tuners or extras. Can i get a real deal answer from current owners please? I've also considered finding a good used 2006 or 2007 5.9 6 speed but they are harder to find. Any honest comments would be greatly appreciated. I don't know why Ford and GM offer so much more as factory as bumper to bumper warranty on their trucks compared to the dodge as well. Any light that would be shared would be greatly appreciated! Thanks, Jake

the most of the problems seem to have been solved with the newer flashes . i have an 07.5 and only had problems with mine one time a few months after buying the truck new . since then i have stayed current with all new flashes and have had 0 problems . as long as you leave it totally stock , you shouldn't have any problems . if you ever plan to use a programmer , you would be better off to do the deletes . as far as the fuel mileage : i get 18 on road empty 14 around town and 10 - 12 with a 13k fifth wheel . i know some people have had problems with fuel mileage and the emmissions crap cuts down on mileage but , too many people try to compare these 350 hp trucks with a 185 hp 12 valve .the 12 valves would get 22 + mpg i know because i had one . but , that is not a true comparison . for a 8500 lb . 350 hp truck i am pleased . i can remember the day back in the 70's and 80's when all we had was big block gassers that would'nt get over 8 mpg and wouln't pull a greasy string out of a cat's butt . i love my truck . as far as getting an older 5.9 : the transmissions won't hold a candle to the ones behind the 6.7 's and there is no exhaust brake without adding one . neither of my 5.9's would'nt stand a chance pulling against my 6.7 .

started with 1996 2500 4x4 auto
then a 2004.5 2500 4x4
now have a 2007.5 6.7 4x4 3500 drw mega cab 3:73 rear G56

I have a 07 6.7 with auto. Like any vehicle some will have issues and others won't. I am completly stock and have 57,000+miles. My only problem was a water pump leak and that was covered by warrantee. I get 19+ mpg on freeway and 14.5 in city type driving. My every day weight with tools is 7700lbs, so I am not "empty" weight wise. Pulling my 5th wheel, 12,000lbs I get 10+ mpg when towing thru the mountains and will get 13+ on the flats. A lot of my driving is short drives stop and go right here on the ranch, but on the road I tend to have a heavy foot. Never have seen the "plug dpf" on the overhead warning.
Bottom line is I have no complaints

You said it was staying completly stock then get a brand new one with some good rebates buddy has a 09 he already got 20k almost and no problems. Im going to say it but i think the reliability is getting close to a 5.9. I mean it basically is a 5.9 wit POS exhaust system and a bigger stroke. You prob dont want to hear this but within 2yrs of being out the 6.7 has laid down damn near 800hp on fuel only now thats impressive. Do yourself a favor and get a new 6.7 you will enjoy

Couldn't be happier with mine even with the issues, but overall I am very happy. They tow extremely well. I get about 14.5 in the city and 16-18 on the hwy and 10.5 towing our toyhauler (10.5K) the truck its self weighs in at 7860lbs with toolbox loaded 5er hitch etc. so its not a light truck. If I had it to do over I would.

I haven't logged that many miles with mine yet, so I can't speak for long term reliability. but I am extremely pleased with my truck so far. Going between 75-85mph the other day I pulled 19.3mpg hand calc'd on a 300mile trip. My truck is completely stock and no where near the 20k break in point that everybody speaks of, for getting better mileage.

I'm sure you will be very pleased with the truck if/when you pick it up.

19MPG @ 75-85MPH!?!?!?!?!

Wow, that's better than your 2000 can do. Likely any 2nd Gen really. That's really really good mileage. Too bad I can't afford a 6.7!

i love the truck but there is a power issue. no cel, no lights nothing just no power what so ever.

No problems with mine 26,000 miles so far. mileage going up a little now but the power towing my 13,500 lb. fifth wheel and the control with the exhaust brake is amazing. my old 12 valve doesn't hold a candle to it in towing.

2007.5 DODGE 6.7 1-TON 6-speed stock for now. B&W turnover ball.
1994 DODGE 5.9 3/4 TON AUTO, DD4 injectors,191 DV's, 0 plate,3K GSK,Timing at 16.5, Volant air intake, Straight pipe 4", BD tranny.
1999 VW jetta TDI 5-speed 50 M.P.G. +
2006 Jayco Talon 5th wheel toyhauler 36'
1969 Chevy stepside still stock but not for long
