The best time to go to Magic Mountain is in October, the last week they are open during the weekdays (the week of Halloween) on that Monday, Tuesday, or Wednesday.
You can replace the hybrid battery pack for $600â$2000. It will be more expensive to do it at the Toyota dealer, and the model of the car also affects price. I have had 3 Priuses in my family, and only had to replace one battery pack (200,000+ miles). I ordered a replacement battery pack from a rebuilder and had it shipped to my mechanic, who had no problems changing things out. The total cost was $1200, back in 2011.
My 2001 battery failed today at 70K miles and I was told the replacement would be $3700 installed... that's the $2299 quoted here PLUS installation and tax. I have the * asterisk model which is out of warranty in 8 years, not 10, because I was an early adopter and evangelist for Prius. I feel betrayed and duped.
