Currently own a 2004 Golf TDI (for 14 years), a 2016 Golf GTI (for 2.5 years) and a 2012 Chevy Volt (for 3.5 years).
TDI has been bulletproof, but it's definitely a 16 year old car. Lots of "Personality". She's now the winter ride.
GTI is great fun, but thirsty.
The Volt is great, if it weren't for the Chevy Quality. Battery doesn't really degrade, but something goes wrong every 9 months or so that stops the car from charging, or the engine from operating properly. A year back the motor mount broke... dealership says "Oh yeah, that's a common failure point on earlier 2010s Chevys".... da hell? The connection of the motor to the car fails.... commonly? Chevy gonna chevy, I guess.
We love owning an EV. The cost per mile driven, if it were a car that actually has the EV reliability as advertised, would be great.
Anyway, we're nearing the end of our Voltec warranty period, and aren't looking forward to owning the volt outside of the warranty, due to the every 9 month "Oh Right, I'm a Chevy.... CLUNK!!!!" pattern. We're loving the EV aspect of the car, but aren't sure what to buy next. We were originally thinking a Soul EV, but all these stories of degradation are pushing me away from KIA. 2020 Kia/Hyundai look great and all, but it's not in the budget, especially if there's issues with degradation.
As I understand it, EV batteries are just like cell phone batteries, in that, if you keep their SOC between 20 and 70% generally, they tend not to degrade. Go ahead and charge it right up to 100 when you know you'll need that extra range, but try to avoid it when you can. So then, the true daily range of an EV is usually 50% of stated range.... and if you live where there's a real winter, and you drive on the Highway (I am a yes to both of those) then true daily range is actually 33% of the stated advertised range.
Is this charging methodology common for these cars with consistently dying batteries? I am starting to lean towards an off lease Prius Prime with all the stories of battery problems that I'm seeing.
