Poor acceleration and deceleration at low speeds.

Hello all,

New Genesis owner here. Love the car. Think I got a good deal on it, but there's one thing that's really bugging me I thought I'd ask you guys about.

While accelerating slowly (neighborhood driving) through the 20 to 35 MPH range, the acceleration is uneven and the car "bogs" slightly at certain small bands in RPMs.

It feels like:

a) I'm rolling down a road with strips of fresh tar of various widths
b) the fuel injection is dirty
c) the bogging and compression you sometimes feel when you downshift a manual transmission car

Once I hit 40, things feel smoother, but I think that's because it's finally in the last gear.

I feel the same thing while decelerating as well, so am now suspecting the transmission as I've never known an auto transmission car not to smoothly coast to a stop as it slows and downshifts.

Thanks in advance for any thoughts about this.

What model do you have? V6 or V8? And what year is your Genesis?

Honestly you have to get used to driving the car to make it smooth. I almost crapped myself when I got in my 13rspec...now I can drive like an 80yr old lady in traffic or a lot faster when I want.
Just get used to the shift points and the transmission will learn your driving habits also.

Great car and I love mine!!!

Last thing...if you want to drive "sporty" all the time, then drive it hard all the time and the car will learn your habits. Then it will feel more normal to you the next time.
I have noticed if I am very easy when coming home then the next AM, if I try to plant the gas...the computer really holds back.
Whereas if I drive it hard, park and do the same...I can feel the 429HP as I should!

Thanks.

So are you saying the hesitation while accelerating and decelerating is due to the previous owner's driving habits and that the car's computer will even that out as I drive it more? How does that happen if it's receiving no input from me while coasting to a stop?

Thanks in advance. I have a lot to learn about it, apparently.
