Hi, im creating this to ser if this is a normal thing or not, we are talking about A220 2019 fwd and the car vibrates at 80-115km/h only when i accelerate if i release the gas pedal vibration is gone. So its only under pressure in the gas pedal, it doesnt matter if im at full pressure or little, the most anoying thing its when i go with 3-4-5 people inside and control cruise at 110 the vibration is pretty insane and if the car its in a bumpy road or sinks in to the road the vibration its expanded in all car.

Thx so much lets see if we can resolve something.

(2019 A250 owner) No, it’s definitely not normal. To confirm it’s driveline and not engine use the paddles to step down a couple of gears. If the vibration changes significantly it may be engine related. If not, it is very likely the driveshaft constant velocity joints.

in any case, get an urgent appointment with the dealer to investigate and fix. If a CV joint comes apart at speed it will cause significant secondary damage.

Hi thx, the gear doesnt matter when it does it does in 4,5,6,7....

The driveshaft joint looks good no grease leaks i dont know

I’ve had a failing CV joint (on other makes) with no external evidence.
