Read complaints for PETERBILT 389 (2017)
Heat from the new def requirements are causing problems. The heat off of the def system stays trapped under the vehicle. Which is causing early wear on electrical harnesses along with axle seals.

And the manufacturer will not accept responsibility for this. *dt
