So how long should I keep my Volt?
@PrivatePilot may have good insight here.
Driving a 2018 with a warranty that started in late 2017. Currently at 110km.
My 2011 is still going strong at almost 200,000km. My sons 2012 has some quirks now but it's nearing 300,000km and although it decides it wants to run on gas more often now in the cold weather (battery aging presumably) it's still a great car.
And in the grand scheme of things, both of these cars are at or nearing "end of life" for a vehicle by most standards where they've depreciated greatly - if they both make 14-15 years of age I'm happy - my 2011 has paid for itself in gas savings alone and continues to save me money daily.
I've had people say "13 years isn't old or end of life!" for a car, but when you think about it, anyone who is still driving a 2008-2010 car...well, it's probably approaching beater territory. Use the Chevy Impala's that were made at GM Oshawa as an example that many people would remember from that era, but reality is you don't see them much anymore as they reached end of life and are gone now.
The problem with EV's is that everyone wants to hold them to different standards and although they totally understand that their 12-15 year old car is worn out and such, they expect an EV to last for 20 years or something.
My wife's 2017 (warranty started in early 2017) still has a battery warranty for another 40,000km or 3 years - we'll almost certainly mile it out before we age it out, but in the grand scheme of things I have zero worries honestly - failures of Gen2 batteries are almost unheard of, and the few that have failed have done so well within the warranty period. We will drive this car into the ground. When my 2011 finally suffers some major failure I may either swap whatever fails (the batteries can be had now from wrecked Volts for a few thousand dollars) and keep on driving it, or maybe eventually go back to one full EV and buy a Bolt when the price on the 2016-2018's come down more.
The reason we got our 2017 for such a good price was because the guy who owned it was in full panic mode when the bumper to bumper warranty was expiring, either not understanding that the battery and drivetrain warranty extended for many years longer, or just not wanting to own a vehicle without a B2B warranty. Me on the other hand couldn't care less. It's been an awesome car and will be for many years to come.
