Hi all, Now that the weather is colder I have noticed some strange shaking with the regen breaking on my 2013 model s. On cold mornings when I start driving it will start to shake pretty hard at low reg braking speeds (no feet on either pedals). The moment I press the brakes it stops. It appears to only happen on downhills and tends to go away once I’ve been driving a while. Has anyone ever experienced this or can they share any thoughts or advice? Since it only happens under specific conditions it’s hard to demonstrate to the service center and they have not been able to help. thanks!
