Greetings!
Brand new M3 Dual Motor Extended Range owner. Overall I'm thrilled with the car! But having one issue that I've seen posted on Tesla forums, but not here. I've searched on this forum and don't see any threads about same issue.
When driving over mountain pass in cold weather (<32 degrees Fahrenheit), I can hear and feel a banging/thunking/clunking noise coming from random locations under the car. First time it happened was when I was driving home from picking up the car. I drove 200 highway miles on mostly flat road without single episode. But when driving over a 3000 foot mountain pass in 22 degree Fahrenheit weather, I could hear banging or clunking noises coming form under the car. Worse when going uphill, but happens on downhill too. Roads were slightly wet, and my first thought was this is ice forming in the wheel wells and getting slung against the wheel well or bottom of the car. But since then I've driven same pass several times with dry roads and had same sounds. Sound is random, can come from front/rear/sides of car. It is definitely originating from the "floor" of the car. You can feel the clunk in your feet and seat. One person described it as "oil canning" which sounds about right.
I've seen other descriptions online of similar sound when supercharging. I've only supercharged a couple of times so far, but did feel/hear one similar "clunk" when I was sitting in car while supercharging.
I've seen other descriptions of it sounding/feeling like metal in the battery pack "flexing" due to thermal changes. I've also seen people attribute this to contactors in the battery pack, or battery pack heating/cooling system.
But I would definitely not describe this as a "normal" sound for a brand new high performance automobile. I'm sure it wasn't designed to make this noise. The real question is what is the cause, and what are the potential remedies?
I tried to call Tesla Support the other day when it was doing it, but the hold time was >20 minutes and I couldn't wait. I'm planning to call them again in the next few days when I have more time to trouble shoot with them. I'm hoping they won't want me to bring it in for service since I live 250+ miles from nearest service center, and so far I can only reproduce it when going over mountain pass. Maybe one of their mobile techs will come and I can demonstrate it for them.
Has anyone else had similar experience? Has anyone had productive response from Tesla about this?
Thanks!
Jim
