612 Road Vibration and Shake in Idle

You may need a re-alignment or there could be an issue with ball joints / tie rods, which are known to fail.

I've driven mine over the less than perfect roads and it is very stable and vibration free - and it is scheduled to have the the tie rod ball joints replaced in a couple of weeks.

Did the Ferrari mechanic actually drive the car or did you just speak with him only?

Best thing to do is drive the car WITH the mechanic in the car as well.

 

You need to get it looked at..... I have never had any issues like you've described. The 612 is supposed to be what you expected and that is what my experience has been.

 

Could be a bad motor mount on the vibration. What are the dates on the tires? Old tires can be a problem, too.

 

Any squeaks when you press down on each corner of the car?

 

The two issues you describe would most likely be related, and if so, then tires and alignment are probably not the issue. I would say it is an engine/drivetrain issue.

One thing I would definitely not do is take it to that so called Ferrari mechanic. What you are experiencing is not normal.

 

Agreed, not normal. If car is left and not started for a few days or more you may get a mild shake for 5-10 seconds after start up but should go away immediately. And on the road it should be smooth like silk. That's sort of the point of the 612 - a refined GT

 

I notice a little bit of vibration at idle, but it's smooth on the road. I think I'm more sensitive to the idle vibration because my other car is a Tesla...

 

Check the balancing on the rear tyres - vibrations in general come from rear wheel balancing.
Also check if the car pulls when no hands on steering and car moving.
Also check bushes, track arms and rods... But i feel that it will be the rear tyres that need balancing

 

Just another thought: it might simply be a faulty spark plug that fires occasionally only. I had that once (550, the faulty plug brand new from Ferrari, by the way, I was already afraid that something more serious had been done wrong...) and the driving experience was quite similar to yours.

 

As he stated in the beginning, the vibration is there in idle, not only when the car is in motion.

 

I'd also tend to think along the lines of a misfire, timing issue, spark plug wires, plugs etc. An engine not firing right, can vibrate like crazy.

 

- At highway speeds, there is too much vibration in the cabin. I changed tires and rebalanced the wheels. It's definitely not a rebal issue. I can feel the steering wheel and the seats communicate very small road surface irregularities that my eyes can't see when I look at the road. Believe me, roads in Dubai are silky smooth, yet the car is continuously telling me that they're not. Again, I expected a GT that is built for covering large distances to be more comfortable than this at highway speeds in 6th gear.


"At Highway Speeds"!!!

 

Misfires to the point of causing a vibration should throw a code and set the CEL - doesn't sound like the OP is having a CEL...
