Toyota Sienna 2018 LE won't start

Asked by Guru9F5M6Y Nov 20, 2022 at 11:53 PM about the 2018 Toyota Sienna LE 8-Passenger FWD

Question type: Maintenance & Repair

I need to jumpstart my car every time I need to start it. KOEO I get message
on the dashboard "Check charging system". But after jumping and when the
car starts, oddly there are no warnings on the dashboard. Car reliably starts
and runs every time I jump start.

Voltage Test - The voltage at battery terminals does NOT go over 13.79V
when I accelerate/speed up with the car in P.
Disconnect red terminal w/car running - The car did NOT stop

What do you think is the problem?

If it says check charging system then have a shop check it. Now as this has a computer controlled charging center unhooking a battery cable with the engine running can and will fry electronics. I had a customer that did the exact same thing you did and it fried every electronic component the vehicle had. Back then it was well over 3 grand to get it running again, these days probably double that if you can get parts.
