2014 Kenworth T680 Engine problems

Apparently there is a failure of the fuel pump in most models of this cummins isx15 motor, tha when it does fail, shuts the truck down on highway, or worse, lik eit did to me....Send metal shavings into the rest of the motor destroying the motor. There have been recalls for ceramic plungers, which I don't have...And recalls on many years this model was manufactured. I have an extended major component warranty that cummins will not honor since the fuel pump failure is not covered.....Dealer has witnessed many...

A vibration is felt during warm up and becomes very noticeable after shifting into 8th gear. If the air compressor kicks in while the engine is below 1300 rpms this also increases the vibration , again real bad shifting into 8th and air compressor running .Note: I just bought this truck from kenworth sales company , salt lake city, ut I aint even put 2,000 miles on the truck, what kinda of deceitful ethics violations are practiced from this dealership?

Bunk wiring harness is shorting out causing truck to not be able to shut off with the key....And also causing problems with the def system....Shops are telling us that there are trucks burning down from this faulty harness...And there has been a recall for this but kenworth is not fixing this harness and expects the owner to fix it ....
