started just a few weeks after purchase. ck eng light comes on went to mhc in jonesboro had it repaired. no charge just a week off. went to ardmore ok ck eng ligth comes on and truck derates. went to mhc there and was down 2 days said it was wiring harness on def filter replaced it and nox sensor. went 50 miles from there ck eng light came and went 25 times before i made it back to mhc in jonesboro ar. they kept it 1 week and said it was repaired. stayed off for a while came on again went back to mhc put computor on it and regen and cleared all codes. work good for a short while, started missing going into chattanooga tn went to mhc there and number one was missing and then cleared up. they said it need overhead ran so 875.00 later they couldnt replacate problem and said it was ok. made it home and back to mhc in jonesboro and they replaced wiring harness on eng and said all good. came back on for 2 months and took back to mhc in jonesboro they had it the 2nd week in nov till after thanksgiving i believe and said my def line was the problem this time, replaced and i didnt get 35 miles before it came on again. week back to jonesboro and had tripped 7 codes and they erased codes and regen and said it was ok. been in my drive way since then.that was nov 2016, it is jan 2017 went outside and started it j1935 data link code eng derate on ck eng ligth on def tank light flashing. i do not recommend buying a kenworth with paccar motor because they mhc cannot fix problems but sure can charge you for it.
