Loud "thunk" coming from driver side somewhere?

Is it you AC compressor kicking in? Mine does that too and I can hear it loud and clear inside the car but when trying to hear it from the outside it's just a very quiet click.

Congratulations on your new car!
There will be a lot of new sounds, feelings, experiences you'll encounter for the first time with this car that you may not have in the past with others. One of those is the HVAC compressor. You'll never notice it at speed, only when stopped or almost stopped will you be able to hear and feel it. It's definitely startling when it happens, and it doesn't happen all the time. There are many of us here who have confirmed it. There have been times where I have sat in the car with it turned on for 30 minutes or more. I'll notice it happen a couple times, then turn off the climate control, and it stops. Turn the climate control back on, and it randomly starts happening again.

Thanks for posting what happened at the SvC. I am confused though. I thought you indicated you heard the noise (thunk) when you were coming to a stop and not accelerating.

Both ways but when stopping the noice was not always as loud as when taking off. On the testdrive the tech just pumped the acceleration pedal all the way and it was obvious. I never did that test. This was the reason to notice the noice on acceleration only
