Had it installed yesterday, which cost $95.01. The forward PWS sounds like our 2017 Volt and I know from 4+ years of ownership it works for its intended purpose. But I love the sound in reverse.
But as a side benefit when my SA checked me in, he mentioned my VIN is part of a Customer Service Campaign to replace the 3 Pressure/Temperature Sensors that have been associated with Heat Pump failures. So they did that as well. A Mobile Tech couldn't change them.
Very happy camper with our local Tesla Service Center.
