I have a 2012 with 73k miles and I do not have an extended warranty. It wasn't charging completely a few weeks ago. I took it to the dealer and they said it was the 12v battery so I paid just over $300 for a new battery. After a week or so it was back to not charging. I took it in again and they had a lot of problems duplicating the issue probably because the dealer has a super charger but finally after 3 days they said it was the onboard charger. The part costs over $5k and the dealer said they would pay for half since I am so close to being out of the warranty period. The motor was replaced last year at no charge when it was still under the 5 year 60k mile warranty. I have never fully charged the car to extend the battery life. I am thinking of selling the car since I don't have the warranty and am worried about more car problems. The dealer only offered $2k. I took it to CarMax tonight and they offered $8500. Questions: 1. Is there anywhere I can buy an extended warranty? 2. How much do super chargers cost and can I get one in San Diego? 3. Should I just pay the dealer to get the onboard charger? I want a car for the carpool lane for at least another year before I move. Thanks for any advice.
