My vehicles are doing it to - wobbly lightbar 

Got the exact same issue and I know a few others have as well....

Same thing is happening to me but only with Bleep999 models

Ive seen on some other threads that "I encountered this today with one of my models...Found the culplrit to be a copy of chassis in the hierarchy. " - from flwpheonix what ever he means by that

It means that in zmodeler I had accidentally had a copy of the chassis in my hierarchy, which caused everything to wobble like described.

ah right, well take it there is still no solution still then that im aware of

Easiest way to tell is open the model in OpenIV and see if there are two chassis in the list...if there is, then that is the culprit

righty and how you go about fixing it then, im useless unless its a drag and drop situation if you dont mind helping me 

If it does have 2 chassis' in the list....then you are S.O.L. unless you have the original model, or the model is unlocked.

well... damn alrighty then well cheers anyways

Now we just wait

Has anyone found  a fix for this issue yet? 

I'm encountering this too. Not just Bleep999 models. It's very odd indeed.

Is there a fix?

There must be fix somewhere. Some sort of setting in a file that needs modifying.

Also having the same issue. @Double Doppler did you find a fix?

It's a model problem that only the model authors can fix as they have the unlocked files. I've messaged Bleep999 about it and he replied that he has no intention of fixing them. I've since switched to new models. 

@Double Doppler It can't be a model problem if they weren't doing that in the first place. There has to be a file that was modified in the December patch that changes something to do with car model extras or something similar.
