Start-Stop causing damage?
How many of you use the start-stop system on a regular basis? I had issues with vibration in my 14 prestige at idle and it was determined that the motor mounts and / or transmission mount were bad. All 3 were replaced and the issue seems to have gone away.
Though driving today with the start-stop, I had a thought about the engine turning over repeatedly and possibly causing damage to the mounts. There was no explanation about the mounts being bad, just that it could be a defect. Thoughts?

There are tens of thousands cars with the start stop system. If using it caused damage to the mounts, the mounts would be made stronger.
Sounds like you had one bad engine mount which transferred more force onto the other two. The dealer elected to replace them all.

I also have a 2016 3.0T. *** comes on by default but can be coded off permanently, as we did last year. Search this forum for the thread with the specific instructions. I posted in it, so that would be one way to search. As I recall, it was a quick and simple matter of a value originally set to "20" being changed to "16", saved, and *** never came on again, and the LED indicating the off status stays illuminated.
