My 2021 Hino L6 is wearing me thin

Bought a brand new L6 thinking I'd get a few worry free years but I've had more warning lights than a Christmas tree. Is anyone else dealing with regen problems under 40k miles?

You're not alone in this and as far as I've been able to see, it's a problem with trucks that don't see a lot of highway time. Sustained speeds for about an hour or so help with passive regen, so it's something you might think about. Also, it's a new truck, it'd be heading to the dealer in a heardbeat

You nailed it. Most of our routes are local stop and go so the truck rarely sees long stretches. Brought it in the first week and the dealer ran a forced regen and diagnostics. Is there a way to monitor how often passive regen is actually kicking in?
