Not starting

Getting the car's warning codes read is a good next step to find out what the problem is... This can be done via phone apps like Dr. Prius and Hybrid Asst., just make sure to buy the right OBD2 reader: Hybrid battery diagnostic and repair tool for Toyota and Lexus You can also use Toyota Techstream software via: Mini VCI J2534 OBD2 Diagnostic Tool Code Reader for Lexus Toyota Techstream New | eBay

Also many people will come here and say their car had a brand new hybrid battery put in a while back only to discover that the battery was a rebuilt pack, not a new one, which doesn't last as long as a new one.

 

Asking for help without having the codes is like asking a blind man what color something is. You might get lucky but you will probably get a wrong answer. You need to get the codes.

 

Did you replace the traction battery?

 

If you disconnect the 12v battery for 5 minutes the codes will be cleared and you might be able to get your car to not notice the problems you're having for a few miles so you can get to an auto-parts store and probably by then the red triangle will come back and they'll read the codes for free for you, but they won't be able to read the sub-codes. But at least that will get you going in the right direction.

Or the more expensive option is to get it towed to a hybrid mechanic. Only option I recommend against is going to a dealership who will rip you off... On the other hand, if the new battery pack was installed by a dealership, it should still be under warranty, so no harm in trying to get them to fix something for free.

 

welcome!
check your battery connections, especially negative to ground. make sure they are clean and tight.

then test the battery. it should read at least 12.8 after being off several hours. if not, put a smart charger on it, or return it.

if it still won't start after all that, you may have blown a fuse. that will take some time and testing.

if all the fuses are good (there are a few important ones) codes will be the next step

where did you get the 'new' hybrid battery? a toyota oem installed by a dealer would have a 3 year warranty
all the best!

 

Perhaps he lives close to a member that has a scanner? Can’t tell as he didn’t list his location.

 

Yeah the US of A is pretty expansive .

Maybe he’ll return and we can get a better geographical idea .

 

Hah... All you commenters think you'll have friends if they return... But you should know by now that they rarely do... Face it, we're all just here talking among ourselves about someone else problem who's not even around, not even paying attention anymore... What a sad life all you PriusChatters live.

 

Perhaps but I am gaining knowledge.

 

does this mean you disconnected the hybrid battery and cleaned your hybrid fan, if so snap the orange hybrid battery plug down. your plug may not be seated right, push it down.
