Here to vent. The adaptive cruise control on my 21MYLR has NEVER worked properly since buying new in Oct 21. From day one it slams on the brakes when passing a semi truck on the interstate. Happened again this morning with my family in the car- Had my own lane to pass the semi, but the car slams on the brakes for NO REASON. Reported it to Tesla service and of course the said a fix is coming- Well, fact is I bought a $57k car TWO YEARS AGO and have never had a properly functioning CRUISE CONTROL. This is so absurd, and I'm tired of giving Tesla the benefit of the doubt on this issue. Give my car a properly functioning cruise control or give me $$$ back on my purchase to account for TWO YEARS of putting up with this dangerous driving behavior.
