Then why did Edmund&#x27;s car need FOUR drive units in two years?<p><a href="http:&#x2F;&#x2F;www.edmunds.com&#x2F;tesla&#x2F;model-s&#x2F;2013&#x2F;long-term-road-test&#x2F;2013-tesla-model-s-drive-unit-iv-the-milling.html" rel="nofollow">http:&#x2F;&#x2F;www.edmunds.com&#x2F;tesla&#x2F;model-s&#x2F;2013&#x2F;long-term-road-tes...</a><p>That&#x27;s the FOURTH drive unit (3rd replacement) their Model S needed.<p>The fact of the matter is, my Ford Focus (and most people&#x27;s Toyota Camry from the 90s) has needed less maintenance than than the two-year test Edumnds did on the Model S.<p>Unless you like paying $90,000+ for a car that dies in the middle of the highway as the drive unit completely craps out, I&#x27;m not sure if the Tesla Model S is actually a sign of Tesla&#x27;s manufacturing prowness.<p><a href="http:&#x2F;&#x2F;www.edmunds.com&#x2F;tesla&#x2F;model-s&#x2F;2013&#x2F;long-term-road-test&#x2F;2013-tesla-model-s-stuck-on-the-freeway.html" rel="nofollow">http:&#x2F;&#x2F;www.edmunds.com&#x2F;tesla&#x2F;model-s&#x2F;2013&#x2F;long-term-road-tes...</a><p><a href="http:&#x2F;&#x2F;www.edmunds.com&#x2F;tesla&#x2F;model-s&#x2F;2013&#x2F;long-term-road-test&#x2F;2013-tesla-model-s-is-the-third-drive-unit-the-charm.html" rel="nofollow">http:&#x2F;&#x2F;www.edmunds.com&#x2F;tesla&#x2F;model-s&#x2F;2013&#x2F;long-term-road-tes...</a><p>And considering the widespread reports of issues with the &quot;simple electric&quot; Drive Unit, I&#x27;m thinking the electric drive unit is a lot more complex than Tesla&#x27;s marketing slides indicate.<p>---------<p>Worst part is that this isn&#x27;t anecdotal evidence.
