No doubt there is risk with both. But Tesla batteries are much, much higher capacity - if their battery price is $20k then GM‘s should be less than $4K. And frankly replacing Tesla’s battery covers the vast majority of potential drivetrain issues. with the Volt, transmission and engine are certainly potential issues even after you replace the battery.. Also the Tesla appears to come with full warranty and compared with the 3 year warranty GM gives you.
I was a huge GM supporter - I am not the one that abandoned this vehicle and it’s owners.
Not exactly. The Tesla has a drive unit, same as the Volt. The warranty that comes with a replacement Tesla pack is
not the full 8 year warranty, and people are seeing failures around the same timeframe we are with the Volt. With the Volt engine, unless one does something stupid to it, I expect it to far outlast the battery. Even with the high number of miles I drive, less than 50% are on the engine. These are more similar than opposites.
The one way in which GM and Tesla are moving in completely different directions is the battery design. Tesla is moving toward a "structural" battery, meaning the entire battery will need to be replaced instead of a module. The entire battery is filled with a rigid "goo". The new GM design is more modular, for lower cost section replacements.
Now don't get me wrong, I agree GM should be fully supporting the Volt including new replacement packs. However, one can't have blinders on to reality, and expect they won't have very high $ repairs on the Tesla as well.
As far as the 23k you were quoted, either GM has significantly hiked the price to ensure replacement packs are available for warranty purposes,
or it's the dealer's (really stupid) way of saying they don't want to do the repair. Most who have posted here on the replacement cost, have done so in the 11-12k range.
