14,795 miles....Only problems were side body moldings bubbled, rearend driver's side seal leaked. Fixed under warranty. Truck has lots of power. Great fuel mileage (which I will not list because I do not want to argue how good my mileage is with a LLY owner). Very pleased with overall performance.

127,000 miles regular maintenance and running great. Injectors went south around 93K miles other than thatn runs Great! Running Hypertech 90 24/27....after injector failure and no issues. I tow a 3 horse trailer loaded all the time and have been extremely happy. Plus I get 17.5 around town and up to 21.5 on highway running the 285s Used to be a dodge owner.....1 ton SST diesel....dog...dog....dog... love the allsion transmision. The ally and duramax are the only reason I would not switch brands. I love the duramax too but I run whatever gets me to where I am going reliably.:)

26K for me too. Only engine issue is periodic idle surge, but it won't do it when I take it in so they won't/ can't fix it.

27,200 so far and no engine problems. The only thing I have encountered is a broke drivers sear back that would pop when I accellerated from a stop.They replace the seat back. Also the passenger side front boot over the steer linkage was torn. They replaced it also no charge.

64K no majore issues. Reflector on LR door panel (inside) came off and replaced by GM, radio know paint came off as well as behind drivers climate controller, (Just started last month), Starter solinoid was not engaging GM replaced whole starter at 29k, last week the light behind drivers side climate controller quit. Duramax / Allison no problems.

30,000 and going strong had some warranty work done on the 6 speed maual tranny twice, recently developed a windshield leak that puddles up under the clutch pedal. But heck that what rags are for.:rolleyes:

80k+ miles, & I haven't had a single problem (knock on wood!). One of these days I need to take it in to get the tailgate cables replaced, but I've never needed to go back to the dealer for anything.

Brett, go look at Broker's list of trucks in his sig....

I think GardnerTeam also ran up huge miles on his.....

Lots of guys around the site with LB7s that run perfect every day. I'm one.

SRODE,
What symptoms did your LB7's injectors give you? I just turned about 15,300 on mine and just noticed this week that it is starting somewhat harder in the morning and it is vibrating more noticeably at idle in gear. Seems to run perfectly other than that with good power and no visible smoke. My dealer is a 100 mile round trip so I don't want to just run down there scared. My truck is bone stock except for a high flow panel filter and I changed the fuel filter at 15K. I cut it open and it looked fine. Thanks

Mine was a little slow starting and I could smell a hint of fuel in the morning then a week later while towing it was knocking and blowing clouds of white smoke under a load.

SRODE,

Wow, that happened quick. Mine has started fine the last couple of days and I don;t smell any fuel. Thanks for the info.

'01 3500 dually with 194,000. 5 new injectors at 120,000 and just went in the shop for low power and mileage. Other than that it's been flawless.
