My 2011 Sienna with 70,000 km (45,000 miles) died on us after 4.5 years. It sits outside and we live i Toronto. Toyota has cheapened its batteries and these are no longer maintenance free models.

My dealer tried to tell me that replacing a battery needs a throttle body service - ever heard of this?

I guess I do not get the relationship between the throttle body and the battery - can someone enlighten me?

The Toyota dealer recommended this for my 2014 RAV4 but made no mention of it when the battery was replaced on my 2011 Sienna last year.

BTW, I had the RAV4 battery cold tested today and it read 12 and something like 425 CCA which they said was enough to get through another season.

That sounds a lot like what the dealer service guy was trying to tell me but that means a battery change is $192 plus $65 for the TB service. In Ontario, with tax that is almost $300! I was trying to avoid yet another expensive service when the car otherwise runs fine.

My Sienna is only a Canadian LE so not much content but I think that I did have the TB service a few months before the battery change so it was skipped. The RAV will be 4 years old when the battery gets changed so looks like TB service might not be a bad idea.

Thanks for the great info.
