Thinking of trading for 2015 rubicon

I am thinking of trading my 2013 Can-am 500 et for a 2015 Rubicon 500 dct eps. The dealer agent said that after 100 miles it has to be brought in for a valve adjustment and so on. Also has there been any issues with this machine in the past. I don’t like the engine braking on the outty plus it doesn’t have a good traction lock system, I’m a new member to the forum. I have had 5 different atv’s, any info would be appreciated. Thanks
