Hey Everyone! I have an 2018 MDX with 20,500 miles on it. I bought it new. In the past couple of months I have noticed it shifting hard to the point that I look in the rear view to see if someone has bumped me from behind. This hard shifts occurs around 30-40 mph in slow moving traffic/neighborhood driving after the transmission heats up. It also only occurs in normal mode never in comfort or sport. I have taken it to the dealership and was told this is normal, and to just drive it in the other modes. Anyone else have this happening? What other routes can you take to get this issue solved because it is definitely not normal? Any advise would be appreciated. Thanks.
