Poll for loss of acceleration issue

[E3 in 2020]

[

Recently purchased a 2026 GV70. On a couple of occasions, in "Comfort" mode at low speeds, the acceleration hesitates. I have to depress the accelerator about half way down and then the engine jerks and accelerates. If it continues I will bring car in to have it checked.

Update on 10/3/25: Brought car in to Genesis dealer where purchased. It's been there almost 2 weeks with no definitive diagnosis. Very frustrating!
Wondering what my options will be if not fixed very soon. "Lemon Law" ???
Purchased only 3 months ago, with 4K miles on it.

So problem here on a 2025 GV70 with 6000 km

Did they resolve the issue?

Returned the car to me claiming it was repaired.
Driving the car home, problem was still there within 15 minutes!
Will bring to a different Genesis Service Center.

I just had the same problem on my 2024 gv70 15,000 klms. Started my car this morning and very rough idle. Drove off but wouldn’t accelerate. Would only do 30 Kohl’s and maybe 3,000 rpm. Had to park it. Got an appointment for Tuesday I’ll get them to row it in.

Got home 3 hours later tried the gv70 started up and drove normal? I have an appointment Tuesday for unrelated isue, a recall: sofrware update? I report the issue we shall see.

Experienced the same with my '22 GV70. Turned out to be the low pressure fuel pump in the fuel tank. Dealer repaired. No issues since.

had the same trouble of no throttle response at initial step down and then all of a sudden rpm would go to 4000 rpm and trans would sound like it down shifts I would have to get out of the pedal so engine would not overspeed, has been to 2 different dealers and told nothing wrong. HELLO !!!!!!!!! there is definitely something wrong the thing can't be driven without playing with the gas pedal .This is a 2006 with 2000 miles on it. HELP

Has anybody figured out a guaranteed way to duplicate this behavior? I am taking my car in for maintenance in a month or so and I thought I'd report it to them. It seems like it should be a recall issue for sure due to the safety concerns. It has happened exactly twice to me this year. I fix it by using the paddle shifter to upshift.

just got my 2026 gv70 back from the shop and they fixed the hesitation problem by replacing the coolant pump.I don't know what that pump has to do with it bit the suv now runs perfect

Thanks, my question was about how to duplicate the problem so that my dealership can see it, otherwise it's just a transient problem that will be difficult to repair unless witnessed. From reading the thread, it appears that there have been several solutions that seem to fix it which also makes me wonder if everyone is talking about the same issue or a different one.
