Chevy Bolt Is Chevrolet’s Most Reliable Vehicle Consumer Reports is out with its latest car reliability study, which gives us a chance to visit the oft-repeated statement that electric vehicles are more reliable than their internal combustion counterparts. Here, in the case of the Chevy Bolt, we find this to be true. Though the Chevy brand only ranked 18th in reliability overall, its Bolt was its most reliable model (the Camaro was its least). That's great new for Bolt buyers. Not so great are the electric reliability marks for other marques. BMW's i3 got ranked its least reliable model. BMW was 5th overall, so reliability is strong across the brand, with its 2 series taking the lead. Taking that into consideration, the i3 probably is pretty good when compared with models from other brands, but it's a little weak within it. (From what I've read, though, the i3 seems to be pretty well for owners. There have been some problems, expected when you have a new vehicle, constructed in a new way with new materials -- the i3 has a carbon-fiber body shell -- but since the motor mount issue has been dealt with, it seems solid for most owners.) Which brings us to the Tesla Model X. Ranking a lowly 21st place overall -- actually up 4 places -- with only two models the X has been notorious for issues with its falcon wind doors. Especially early on. Ultimately, Elon believes in the power of engineering, so while he's unlikely to put these doors on the upcoming Model Y crossover, the X's of the future will probably have them. Hopefully more reliably engineered ones. Anyway that's three of top EV brands. The Leaf is neither the most or least reliable Nissan. All that to say, it's probably wise to take proclamations of EV reliability with a grain of salt. Yeah, they have a lot fewer moving parts, but the components and software they lean on don't have the century of development that internal combustion vehicles do. Also, as we see with the Model X, problems aside from drivetrain can arise when new companies get into the game and try novel approaches to various aspects of automobiles.
