My 2012 has 2400 miles on it and until recently I have not given it much attention as far as maintenance, I would get it to the dealer once or twice a year for service and do nothing in between except check oil and water. I have had a total of 5 issues, the temperature sensor, oxygen sensor, horn switch, U-joints and rear shock absorbers. When the u-joints went bad it caused the rear differential to flex up and down until the mounting bracket fatigued which caused a part of the bracket to break loose, I welded in a new mounting plate and changed the u-joints and all is good, the rear shock reservoirs were pressing hard against the edge of a plastic body panel and the edge of the panel was literally sawing into the aluminum reservoir, I cut away about 3/8" of plastic about 4" long to give the reservoir some space, the shocks are fine but I don't think it would have taken much more time before the reservoirs would have been punctured, I did a post with pictures on this problem a few days ago. I feel that the mounting bracket was too thin and the shocks rubbing the panels was a QC issue, the other items were minor and you will find that with any ATV, car, boat etc.
We hear about the problems on this forum because some like myself had a problem and came here looking for an answer, I would think that the number of problems posted on this forum is very small in comparison to the total number of units that CFMotors has produced over the years.
