This probably also concerns most of us, or at least remains in the back of our minds.
The RAV4 EV come with a lengthy warranty on the very expensive Tesla supplied battery and all of its electrified drivetrain components; 8 years or 100,000 miles whichever comes first. I originally purchased Toyota's extended warranty to cover the rest of the car for 7 years, because the standard "whole car" warranty expires in only 3 years. However, after only a short time with my RAV4 EV, I found it to be of high quality and "the new stuff" contributed by Tesla seems very well engineered and iseamlessly ntegrated in the car. The battery is not warranted for "normal" degradation, as is true for all other EVs as well, so I decided to cancel my extended warranty and save nearly $2000.
I think ALL EVs carry a considerable risk in terms of potential battery pack degradation over time. However, there is far less risk with respect to the durability of all the other new automotive technologies in electrified vehicles. The long term reliability and durability of any of these cars has yet to be fully proven in the real world. However, high density, Li-ion battery cells have been around for almost two decades, used in a wide variety of electronic devices subject to lots of abuses in the real world, but they seem to have a pretty good track record so far.
Sure, Tesla could vanish in a couple years should the economy take another huge hit, having already emerged from a fairly precarious financial condition over the past few years. There are NO GUARANTEES. However, I have far less concern about Toyota, the leading automaker in the world.
The best reassurance we have about the future of this so-called "compliance car" can be gained from the first generation of the essentially the same car, with only 7 years of production from 1997 to 2003. To wit, a large percentage of those cars are still in real world service, some with over 200,000 miles. Those cars also continue to have a fairly high resale value. Even fewer of those were manufacturered in total compared to the committment Toyota has publicly stated for the new model. Nearly 10 years after the old model was discontinued, I have not heard any horror stories about lack of spare parts and their current owner suffering from any lack of Toyota customer support.
Still, there are no guarantees!
Nevertheless, life is too short to worry about things we have no control over, or about things that have yet to happen and nobody knows whether they ever will or not. The bottom line . . . the new RAV4 EV is a great car to own in the here and NOW. Plus, it is truly fun to drive! I am so happy to be a real world RAV4 EV driver who is not dependent on any gasoline to keep it running. It is so much better to drive for the sake of cleaner air and protecting the planet for future generations.
It is a compliance car but that's a "good thing" when you really think about it.
