On our 2017 Coachman Cross Country Motorhome with a Cummings motor and Freightliner chassis with 13000 miles we are experiencing our 4 time with DEF system failure The first 2 times the Motorhome was under warranty and had to be towed to a Freightliner repair facility. On October 6, 2021 on our way to Mississippi lights came on for the DEF sensor with a light saying to shut the engine off We made it to a repair facility that was able to replace the system at a cost to us of $1500.00 On October 5, 2022 on our way to Mississippi again approximately 1year to date the lights signals for the DEF failure came on on the East side of Baton Rouge. We once again were able to go to the same repair facility in Mississippi but this time the repair could not be made and we were forced to camp at the repair facility yard for 3 days due to the weekend and now are told our Motorhome has to be towed to a Freightliner facility 25 miles further East from where we are We understand there is a bypass code through Cummings and don’t understand why we have experienced 4 DEF sensor failures and the previous Freightliner facilities have not corrected the problem on our RV
