Hi all I have a 2014 i40 and under acceleration at about 2000-3000 revs the car wobbles and u can really feel it if your legs resting against the centre console. You can't really feel it in the pedals more engine/body if u know what I mean.crusing you can't feel anything and it's only when accelerating not slowing down, its just got its 4 yr health check all fine, hyundai mechanic said wobbles down to wheels need balancing.. I thought otherwise and recently reconditioned all 4 wheels plus new tyres and wobble is still in it. Its got 96k I know high mileage but full service history with leaseplan it's been very well maintained. Its the 1.7 diesel 116bhp.anybody any ideas? Flywheel imbalance maybe?
