My dealer looked at my 40 month old 23kmi '15 CRV for $140. Upon the need for the TSB to be performed the inspection charge was waived. I'm pretty happy with it. Mine was like mode 3. However TSB 16-053 might be a newer bulletin on the same issue. I just got this done last Wednesday. And you will lose 0.7mpg. It feels so much better to drive I wish I had complained sooner. Since day one I referred to this drivetrain as weird and twitchy. Feels better, to me. Or in my head. PleasedI purchased a 2015 EX AWD in April 2018 with 26,000 miles to replace a 2009 EX totaled in a black ice accident. In October, when it starts getting cool in South Central Pennsylvania, i noticed a vibration in the seat between 40-50 mph at 1100 RPM - traveling on flat roads. I found after a wed search TSB 15 046 that describes a repair to my problem exactly. Does anyone have any experience with this repair? Did it solve the vibration issue? Did it affect gas mileage?
