@ARK, you are in California. Battery warranty mandated by the State is " 10 years/ 150k miles battery or other energy storage device". This has been true since about 2003, I believe, for California. Therefore any hybrid, PHEV, EV purchased new in California has that as a battery warranty. This may be different from the rest of the US.I wish the battery warranty was a little bit better in that presently the battery's capacity has to fall below 70% before they would replace it. I understand it's for 8 years/100,000 miles and maybe 70% charge at 100,000 miles after 8 years of ownership is not unreasonable degradation, but what happens if you have a faulty battery that is, for example, only holding 80% of a charge in year 2?
I'd be more inclined to consider the extended warranty if it included a more robust safeguard as to battery degradation.
Anyone seen the warranty manual yet for the MachE?
