This article addresses mostly routine Maintenance, which is not the same as reliably or its affects as the vehicle age. It does not cover what are know to be common failures such as motor, battery, DC-DC converter, heater. Tesla, Nissan, Toyota have all had teeth cutting issues. Currently under warranty but what about after?
If everyone was comfortable with their Rav4 aging gracefully there would not be such emphasis on maintaining an extended warranty specifically for the EV components. If it was an ICE RAV4 most would hot even consider the warranty.
8yr/100.000 warranty on drive train
It is items like dc-dc charger and resistive heater that are costly and why extended warranty is logical.
Since standard warranty is 3 year/36k miles
it doesn't matter if the car 5k miles or is at 25k. you will need extended warranty because of 36 months limit.
I was making suggestion that the milage is less a factor with reliability compared to ICE.
Example is the owner of the rav4ev who had 96k miles on hist car, when (under standard warranty) his battery back was exchanged and only had 10% battery capacity loss
I hear what you are saying, but I don't see your point. You stated that higher miles have less of a technical impact than on an ICE, then you point out that one with only 96k had the battery replaced. Only a small percentage of the Rav4 EV's have reached 100k and battery replacements are a reality. How many ICE Rav4's with 100k are needing major motive system replacements costing in the tens of thousands that were results of normal wear and tear?
What happens to owners when they reach 110k? If they paid $1500 years earlier for the extended warranty then they are covered to 125K. But that is still $1500 they spent and what about after that? Only price I have seen on a Rav4 EV battery was $36,000 but that's been a while.
My Acura has 155k and my Insight had over 230K. The technical impact of those miles was faded paint and a cracked dash. I was still averaging nearly the same mpg as when new. My Insight was still getting 70mpg+.
Unfortunately short term I think you will see a lot of EV's prematurely ending up in junk yards due to repair costs. Over time this will change, but until the aftermarket gears up and the prices come down people simply wont come up with the $5,000 - $10,000 to replace a motor or battery on a car worth $7,000 - $20,000. Even now Insurance companies are totaling EVs because of the cost and complications of repairing them vs and ICE.
I like my EV, I will probably never buy another ICE. And they have many advantages but I would never say for this generation of EV aging well or having a long life expectancy will be one of them.
