Consumer Reports is useful as bird-cage liner. I'm on Chevy Bolt internet forums and facebook groups, for obvious reasons. Both the Bolt and the Kona were subject to main battery replacement (same supplier) and this means someone whose battery was replaced has to answer that the car was in the shop because of it. Black mark.
In the facebook groups, the most common "actual problem" seems to be a bad 12V battery. These cars have been on the road for up to 6 years ... 12V batteries are same as any other car, and they don't last forever. Undervoltage from a dying 12V battery causes all sorts of wierd things to happen, and the symptom of slow cranking doesn't make it apparent before it goes critical as with a combustion-engine vehicle. (Other EVs including Teslas have the same situation.)
They have some glitches; it seems that if you press power-on and too quickly select reverse or drive, it gives a "conditions not correct for shift" fault and you have to power down and try again. Yeah that's probably a programming glitch. But waiting for the "ready" indicator to actually light up "ready" before doing this, works okay. As someone who grew up with VW diesels ... waiting for an indicator light to say that the car is good to go before doing the next step, is something I already do by habit. (Diesels you have to wait for the Rudolf Diesel memorial moment of silence a.k.a. glow plug warning lamp to go out before cranking it, or it won't start)
There's an abundance of complaints like "I plugged into a 350kW charger and the car only draws 52 kW" (Duh, that's all the car is gonna take, no matter how big the charger is), or "How come it's only drawing 20 kW from a fast-charger" and subsequent inquiry finds that it's already at 80% state of charge (The fuller the battery is, the slower it charges, that's just how these things go), or "My charger <the GM supplied one that comes with the car> has a yellow warning light on" (means ground-fault or connection-fault, probably because the cable isn't plugged in all the way, or because you're hanging the charger upside down from the cable or some other stupid thing), or "I can't get the Electrify America / EVgo / Chargepoint / etc charging station to work" (yeah because that's not the car's problem that charging stations suck, either because of being broken or because of wanting "their app" on your phone)
