So how many are happy with their L5P?

So how many are happy with their L5P? In the market for one asap, but for anyone reading all of these threads, one might say buyer beware. How many have them that are actually happy with their 2017? My last Duramax was an LBZ, so I have been removed from the scene for quite a few years.

Don't get caught up in the Internet Amplification Factor - I love my L5P -


Have not seen a single major mechanical failure - the issues we're seeing are likely related to putting a new engine in an old platform, and relearning the steps to make sure it's all hooked up. We're seeing issues with a new build, not engineering issues.

Charge pipes, NoX Sensors, Loose Wire harness, faulty or misaligned Down pipe clamp and TCM resets are the Major issues.

If working out some bugs is a major annoyance for you, I'd wait till 2018, if not, get in on the L5P goodness. It's a different animal for sure.

Absolutely love my L5P, it's a beast for towing... Haven't had any of the issues others are talking about so far, knock on wood. There are hundreds of satisfied owners out there already that you'll never hear from because 1. they're satisfied, and 2. maybe they're just computer illiterate and can't tell us about the goodness...

I am at 65 miles, it had 12 from the factory. So far I love it, not noticing the issues that others have pointed out on here. I think my shift points are good, and it does not act like my old truck in tow/haul mode like others are stating. Mine was built on 2/15 so they might have changed something during the build.

Current:
2014 BMW 535i XDrive, M-Sport

Yours was built on 2/15 and you already have it? Dang, that seems quick.

It sure is nice to hear some positive comments regarding the 17's. Like I said, my last one was the LBZ, and I had an 03 with the LB7 prior to that, both were trouble free; granted I only had the LB7 for a short time.
