Dodge 2006 5.9L Issues

Leaning towards an 06 with the 5.9L engine. Read somewhere there were problems with the lift pumps in the '04's but were they still a problem with the '06's?
Are the injectors and turbo's a big problem with the 5.9's?
I bought my '07 used but with the ECM problems wife think we're jinkxed. She says buy a 1 ton so leaning towards an '06.
Thanks

I have two '06 Dodges. One had the lift pump go out at 30k miles. Had it replaced. truck has 99k on it now, and haven't had any problems since. My other Dodge has 112k on it. Hasn't had any problems with the lift pump. I think it's just a hit miss kind of deal too. The only problem that I've had was the transmission throttle control valve. Thats a common problem with the 48RE tranny,…common enough that the dealers usually keep the part in stock. It's any easy fix too. If you've never done it before, you can have it done in 30-40 mins. After the 1st time, you'll have it swapped out in about 20 mins or less. Also the steel fuel line for the #4 cylinder is known to spring a leak too. That's a DIYer job too.

You can take what this ^^ guy says with a grain of salt. Research his past posts and make your own decision on whether or not you can trust his advice when it comes to RAM/Dodge/Cummins...

His posts regarding Ram/Cummins/Dodge are usually a 4 to 5 on the scale.

Turbos aren't an issue with these trucks.
Injectors are hit and miss, guys running 5 micron (or better) fuel filters seems to have fewer problems.

Baldwin makes a 5 micron drop-in filter.

I had one injector go out under warranty.
And a second replaced under warranty when its performance came up a bit short on the dealer's diagnostic computer.
Have not had any issues since switching to a better fuel filter (knock on wood).

All of the diesels prior to 08ish have seen some injector issues but I honestly don't think that is restricted to the brand of truck. My 06 was purchased by me with near 180K miles. I have had one injector fail open.
I now have near 200K and no other issues. The only issues were with the trans. The transmission is capable of handling only the stock engine. If you increase power you will without a doubt burn out the trans. How fast obviously depends on your driving style. My engine is stock but I know the truck pulled alot in its life since I know previous owner. Trans makes noise but still fully functional. When it dies I will rebuild it with midly upgraded parts.
I disagree with the "all diesels" statement. Mine is 10 years old now with 160k and no injector issues, or lift pump(external) problems. Only major cost has been a transmission rebuild at 154k,three sets of tires in 155k and a water pump for a grand total of $6200. That equates to $ 620 a year or $.04 a mile. I did not include oil,filters in this which are minor cost. JME.

Thanks all for the replies. Sounds like a pretty solid and reliable truck. We do regular maintenance on our vehicles so that's not a problem for us. Our concern is reliability especially while we are towing our fifth wheel.

I have been told by various service people that the '06 5.9 Dodge was their best truck so far.

No issues at all with mine, but I take care of it. Oil changes per book, flush trans, replace coolant, diff oil changes, ect.

I had an 07 5.9 and it towed a lot of miles with no problems. As was said the weak link in I think the 03-06 was the tranny. Never heard a lot of problems with the lift pump. But if I had one that went I would put an aftermarket one in, problem solved.

mine has been rock solid. had some failures (radiator/injection pump) early in life, but I also wrapped the truck around the tree at 12k miles and these components failed within 6 months of getting it back.

so from an engine/tranny point of view no concerns. Like any Dodge, have had to have front end work (ball joints/u-joints) done .

I have 120k on it now, going strong..
