2018 Newmar Dutch Star Other or unknown Problems

“Since purchasing this RV new, I have had the DEF Head fail twice. 1st time was Sep 2019 with a mileage of 14066 and the 2nd time was April 2021 with a mileage of 16018. Both times DEF Header Assemblies were replaced. When these fail the motor can de-rate at any time. Very dangerous when traveling down the highway. Both times the low DEF warning and check engine lights came on.”
