Jazz vibration

[Shahid1973]

Hi my 2011 Jazz automatic has started vibrating alot when I hit 70 plus on the motorway what could this be and how do I rectify it? Thanks

Here's an odd one for you.
I had a similar problem which turned out to be a carbuncle on a front tyre (inner wall). Luckily I found it before the tyre blew.
I doubt that is your problem but worth looking at just in case.

It can have many causes: tires, imbalance in wheels, drive shaft issue or even a cvt problem. Basically anything between engine and road surface.
I would start checking tires and continue from there. Should be easy to locate!
Can you think of something that happened between now and when you did not experience the vibration? E.g. hitting a pothole or driving through Belgium ? That might pinpoint a possible cause.

Definitely check the inner (and outer) tyre side walls as a matter of urgency for any 'carbuncle'  bulges.  I too had one (many years ago).   You might also spot a grubby mark where a tyre balancing weight has dropped off, in which case it might be possible to fix the vibration by having just one wheel balanced. Although alloy wheels are  typically balanced with glue on weights  I have seen clip-on rim weights (of the type used on steel rims) used on the hidden inner side of alloy wheels. 

BTW I have also had wheels temporarily vibrate due imbalance caused by  mud  adhering to the hidden side of the wheel after driving in a  field .    So if you are able to safely check the wheels yourself for bulges, missing weights and  mud   it might be worth doing so.  But ultimately it may be safer to have the car checked at a stop and steer specialists.
