2015 Murano "bucks" at low RPM
Just bought our fourth Murano, a 2015. I notice that when going up even the slightest grade, the engine "bucks" or jumps. My theory is that the tranny is programmed to shift too early to get the maximum EPA fuel mileage rating as I can manually downshift (unload) the engine and it smooths out.
Our last 'Mo (2009) had a strange problem for almost the life of the SUV. Still have it. For many years, the CVT would not "grip" when you put it in drive until you mashed the accelerator pedal some. As if the transmission charging pump wasn't turning fast enough at idle. Well, just before we bought the new 'Mo, we took the '09 in for service (I'm a DIY'er, so my cars don't visit dealership shops often). When we got the 'Mo back, the "grip" problem was gone. Completely. It drove like a different, and better, vehicle.
My theory on all this is that Nissan, as I stated above, initially programs the trannies to get the maximum fuel mileage when they are new. Then after the active year model passes and responding to all the bitching and griping from owners, they update the software to fix the problem.
Anyone else had similar problems?
