It does not help that many new vehicles are built like shit and have complexity for the sake of complexity. Electronic door latches, pop-out door handles, having everything controlled via a clunky, outdated, atrocious GUI, etc etc. These problems are not unique to EV's but a lot of EV's are going to have them just because they are brand new vehicles.
Two of the larger EV companies are new and I think both have quality control issues. I suspect that is probably the bulk of the gap. Im willing to bet that Hyundai Ioniq 5 has far fewer reliability problems than a Rivian.
Just the idea to have to replace a 12k $$ battery pack sends shivers down my spine. I will have to pass on that for now. + the trend with these cars being spy computers on wheels doesn't make it a desirable vehicle for me.
Ok even if the statistic isn't wildly misleading. It's not such a bad thing. How long have we been doing gas cars? How long have we been doing ev's? How does the scale of the two match up.
Tons of resources have gone into the reliability of gas cars. EV's do not have the same amount of time and resources pooled to it. It's not a fatal flaw of the concept.
CR is known for buying cars for its own test fleet, but for its annual auto reliability survey, the organization cast a wider net.
Hybrids have 19 potential trouble areas—all the above minus the charging problem—and EVs have just 12, since they go without things like internal combustion engines, fueling systems, or transmissions.
And as our data has consistently shown, reliability-minded consumers would be best served by forgoing brand new vehicles in their first model year," said Jake Fisher, senior director of auto testing at CR.
Tesla, despite a legion of horror stories, finds itself very middle of the pack in terms of overall reliability, and in general it builds dependable EV powertrains—less so bodywork, paint/trim, and climate systems.
In general, the Asian OEMs dominate the upper end of the reliability chart, although Mini, Porsche, and BMW also made the top 10.
As noted, Tesla placed pretty solidly mid-pack, along with other domestic brands like Buick, Ram, Cadillac, Chevrolet, and Dodge.

This may be anecdotal or a result of them being new and having less documentation/etc, but in my experience when they do have problems it's way more of a pain in the ass to deal with too.
