I received alerts to replace my low voltage battery in my wife's Model 3 and scheduled a service appointment. Today I received a text to confirm my appointment which is tomorrow as well as approve the estimate which was $4,158.67 with tax. Is this a joke, a mistake, or can it be something else? I have read that the cost to replace the low voltage battery is $100 - $300. Any ideas why Tesla would want me to approve an estimate like this and what this is about? I did NOT approve and sent them a message back which they have not responded to as of yet.
