I'd suggest running a good diesel additive at every tank. Low sulfur diesel means lower lubricity for the fuel system. No need to waste the money using the AC/Delco stuff, there are good products out there, I ran Optilube in my duramax's and Hot Shots Secret is also a favorite in the diesel field.

I would have to say yes it is normal. I've experienced that too but across the board on various vehicles and trucks including my previous already mentioned units.

Not the newer L5P but my 2018 never idled rough when in a regen. When it is in a regen they will idle about 200 RPMs higher so it is usually smooth. Same thing with my former LML and the 2 LMMs I had.

while people debate oil filters here on forums, others out there are putting 300,000-400,000 miles+ on their engines without oil/oil filter related failures using whatever the dealer or quick lube places are putting on during oil changes.

No shortage. Plenty in production. That store likely didn't order things correctly or someone came and purchased them all for their commercial fleet. Seen it happen a few times at my Wal-Mart. They were generally back in stock within a few days or a week.

is it shifting up or down when doing it?

I know that the transfer case push button switch was a common failure point on the GMT-800s, and were talked about and fussed about all the time on here way back in the day, hell I had to replace the switch in my 99 & 05 1500s. I just replaced the switch on my 04 2500 but am still getting the message to service 4WD. The switch lights up but will not go into 4WD. What were the other common failure points to be looking at? The fluid is fine as it was recently changed. Has 168,000 miles on it now. Am I looking at needing to replace the TC? Thanks

The GMT-900s are more prone to this. Sad to say. See it all over the place here. Rear wheel wells. The GMT-800s were not as bad.

I'd like to see better reliability. The reliability ratings of most of the GM products have dropped significantly over the past 4-5 years. Other manufacturers have suffered too but GM is really taking a beating here.

got around to driving one. Not impressed at all. Too small inside. Not a practical truck. Nothing practical about it except the engine was quite peppy for a little 6.

So looking at the 2019 reviews and reliability ratings from CR: They mention the 2.0 Turbo has good acceleration Good braking Secure handling Gets bad marks for cabin noise, stiff ride, agility, push button gear selector setup, visibility, and interior qualty. poor owner satisfaction (no surprise there) 64/100 reliability rating. Surprisingly, it ranks just 3 notches below the Honda CR-V, (expected it to be worse) but several notches above the Toyota RAV-4. seems to do better reliability wise vs Hyundai, Kia, Subaru, VW, Mazda, Nissan, Ford, and Jeep models.

Go visit the Ram and F-150 forums and you'll see similar posts. Toyotas even have some problems too, but I don't think quite as bad

What is the latest and greatest t-fluid? These transmissions are very sensitive to what type of fluid you use.

Ariens owns Gravely and they make their own mowers. Pretty good ones too. The engines are made by other manufacturers.

This. And it's almost across the board with all manufacturers.
