Acceleration

Asked by Jul 28, 2017 at 06:35 PM about the 2006 INFINITI QX56 4dr SUV 4WD

Question type: Maintenance & Repair

I have a 2006 infinity qx56 (basically a Nissan
Armada) with 150,800 miles that seems to be
experiencing some acceleration problems. Today on
the way home I noticed from a stopped position my
car had nowhere near the normal getup the large
engine in the car usually supplies. When I push the
gas, even to the floor, I max out at about 2200 rpm,
and have trouble getting over 30 mph. It also seems
like once I hit 30, the car no longer wants to shift. In
park and in neutral, I can easily get it up to 4500+
rpm. The car has always been meticulously
maintenanced, as I am the original owner, oil
change and transmission flush less less than 1000
miles ago. Hoping this is not a major transmission
problem, if anyone could provide any insight before
I have to start writing checks for it that would be
great.
