RV with Cummins 450 engine with 20k miles new, goes into limp mode on major interstate. I limp into a Freightliner and they clear the code do a def burn for and hour but it doesn’t really do it ,charges me 500$. Had to deal w this all this stress afraid to go any further all summer long last year searching for Freightliner repair shops along the way, diverting our trip to be close to a shop, finally take it to Cummins they charge me 4,000$ for fuel rail torquing that they did 2 years prior on a recall, and won’t fix the def problem. I had to take it another 200 miles to another Freightliner where they replace the def head for 1500$ and tell me it’s going to happen again! You guys have to do something about this. If not the people will put Cumming out of business. It’s no way to run a country letting this crap get by. Please fix it!
