Tesla&#x27;s are generally reliably. I bought an original one in 2012, then I upgraded to AWD when that came out. Never had a problem other than &quot;slight amount of moisture in my tail light&quot; which they fixed. There have been a number of reporters who appear to have an anti-tesla bias, notable the NY Times report Broder. His name has become an adjective (&quot;That guy brodered you&quot;). They are physical objects, they can fail of course, but generally they are very reliable, and in my experience owning them over 4 years, have been without issue.
