is regen problem solved on 2017 models?
 

Is regen problem fixed on 2017 6.7s

What kind of problem are you talking about?

LOL what issue as far as the seventeens goes mine has not exhibited it at 13000 miles so far. My first 16 was actual lemon law after 8 days of ownership with such bad regeneration that would shake the truck to the core. The replacement 2016 exhibited it 27,000 miles at which point they traded out the head after changing valves didn't help as I stated I'm glad to report the new truck has not had any issues fingers crossed other than this ****y seat take care LOL

What regen issue?

High altitude regen issue?

I think the OP is referring to the jackhammering/shaking during regen problem. Some of the '15s and '16s were plagued with this issue. I haven't heard of any '17s doing it yet.
