Hello everyone.
I have a 2017 Suburban Premier, I purchased it used CPO w/ 37k miles about a 3 months ago and I’ve notice when city/commute driving when I push on the pedal to accelerate it gets very boggy…
I noticed that when I do this, it feels and looks (on the tach) as if she’s upshifting. If I hit the pedal hard enough then she’ll downshift and take off but to just increase a little speed to keep up w/ traffic she gets very boggy and you can hear it just as you’re driving a manual car on high gear and low speed << does that make sense?
Any idea what could be happening or what’s wrong? Gas mileage is absolutely terrible. On the highway she seems to do better on gas but not by much.
There are no engine lights nor warning on the dash.
Thanks for the help – anything would be appreciated.
Thanks.
