![]() This equates to a 99.977% reliability rate, which is exactly at 5 sigma (surprise surprise!) Īuto industries love to claim 6 sigma design and reliability, but few achieve that outside the Japanese, so 5 sigma reliability is probably average for US integrators like GM. So if we assume a properly designed system fails at 1/5th of that 1900, then you have 380 failures per 1,700,000 vehicles, a failure rate of 0.0002235. Per this article, GM issued a recall when they had "double the warranty rate and five times the complaint rate" which was 1900 complaints on 1,700,000 vehicles. My point was that properly engineered mechanical systems (which Tesla has actually shown real competence in executing), will not have a measurable impact on reliability. ![]() I was being a bit hyperbolic, of course adding an additional failure mechanism in series to a system will increase the failure rate.
