My wife drives a 2013 MDX that just rolled 59,000 miles. We’ve recently noticed that when you’re cruising between 40 and 55 or 60 mph and you’re pressing the gas to where the transmission is slightly pulling at the 1,500 rpm range, the rpm’s will just fluctuate between about 1,300ish and 1,700ish. It’s annoying enough that you either have to let off the gas and let it slow down a little or just press it harder to get it to speed up and drive through it. I’ve also noticed that it shifts WAY harder in all gears now, especially your lower gears when starting from a stop. Anybody got any ideas what the issue is?
