OK, let's assume for the sake of discussion, that some percentage of 2015 Honda CR-Vs vibrate at idle to such a degree that it's noticeable and irritating to those driving the vehicle.
From where I'm sitting, there would seem to be two likely outcomes to the complaints reflected by this thread: 1) Honda agrees the issue is significant enough to require corrective measures of some sort; or 2) the company considers the issue and determines that it doesn't require corrective measures.
With regard to the first possibility, "corrective measures" would (IMHO) require the re-design of the rubber insulators (motor mounts) that are installed between the engine block and chassis when the vehicle is assembled. (This assumes that the company will not increase the idle speed of the engine for the reasons previously discussed -- namely, that "fix" would require EPA re-certification. Not going to happen.) With regard to the potential for a re-design of the motor mounts, this possibility would require analysis, prototyping of replacement components, lab and field testing, and then, depending on the outcome of testing, development, manufacturing and, eventually, distribution of replacement components for installation. Best case scenario: This work would require at least six months of very intense, expensive engineering. And that's assuming the complaints reflected here are significant enough to require corrective measure. Therefore, unless and until HMC determines that there exists a significant problem affecting "X" percentage of Honda CR-V owners -- and I humbly suggest this thread hardly reflects that is the case now -- we are ready to move to outcome number two above.
Finally, it is worth mentioned that Honda's CR-V sales numbers rose 12.6 percent in December on sales of 32,369 units, and 10.2 percent YTD on sales of 335,019. Consequently, those who are urging others to take their complaints to various forms of social media, such as Facebook, may wish to take a moment, reflect on those sales numbers, and re-assess whether their perceptions of this issue are nearly as significant and widespread as they may think.
