Since the most recent upgrade my Model S85 thumps and vibrates for seconds every 20 seconds while in park or drive and not moving. Tesla service picked up the car today, checked it out (no charge) and told me this is a normal function of the AC compressor and is caused by the recent software upgrade. This upgrade is supposed to improve climate control. I presume the flaw occurs only in Legacy model S vehicles. I am not happy. I like the quiet of the vehicle. Quiet was on my list of reasons to spend $100,000. Unfortunately, this is not reversible.
My love for the vehicle wanes with each of the many maintenance issues I have had which are numerous and I fear will soon cost thousands as the vehicle is now out of warranty.
