I had a 2014 ecodiesel, and enjoyed the economy, but got scared off from the early issues. Currently in a Hemi, but can get a decent zero percent deal on a new 2019 classic. Trying to decide if I should do it or not. Have always been a diesel fan, and miss it greatly. Is the 2019 still subject to all of the issues the early models had? I primarily drive in town only, and truck has 3.92 gears. Thanks for any feedback. My 14 got 22 in town and 31 hwy hand calculated with 3.55 gears, not sure what 3.92 would get?
