Weird shake and sound when the car is cold

[Mma178]

Hi everyone, I have a 2021 Stinger with 9k km on board and for about 2 weeks now when the car is cold and I put it D or R and keep the brake down, the car and the driving wheel shakes ( strong vibration ) and also there is an awful sound, there is no problem when in N. The problem goes away after hitting 90 degrees Celsius in temperature. I went with the car at the dealership but there was no error on the tester and the "experts" have no clue about the issue. Did anyone had the same issue?

Well. It sure sounds like a torque converter issue. Or low idle when stopped and in gear.

Find a real mechanic.

Howdy and welcome. I can't offer more than that, sorry. But I'll read any developments with interest (always learning). Do you drop it in gear right away? Because I always wait till the RPMs come down before driving off.

I wait for a couple of min for the RPMs to come down and after that I drop it in gear.

Hi, another member had experienced similar symptoms as you are describing .

And the cause was a faulty torque converter.

Engine Mounts - vibrations

Hi guys! For the past year I've been struggling with a problem that my dealer is simply unable to fix. I have the 2.0 T-GDI. When I start the car in the morning, the engine idles very rough when the car is in gear (D or R). The idle in N/P is normal. After the engine warms up (15 min or so), it...

He is Romanian, I would suggest reach @7Andrei7 to go to the same dealership to diagnose your car.
