When I first started driving the car it paired with my 2025 Moto G seamlessly. However, in the last month, the Auto pairing has been disconnected, and any effort to reconnect generates a message that the pin is not correct.
I know that my smartphone's Android version was recently blessed with the security update, but I don't know how to backdate to a previous version of Android so that...

I looked through the posts where people were having hood latch issues, and some posts touched on this.

An AI overview pretty much spelled out my issues, word for word (in a nutshell, all kinds of false alarm pop up messages and such). The only thing that actually fails when the car is showing these messages is cruise control.... which is a big bummer, as I use cruise control a lot.

The AI overview actually told me that their was a recall on 2022 XLS's.... but Toyota says that was in...

I've suddenly realized the lithium battery in my 'Blue P' is roasting! I've researched as best I can, and the only advise seems to be park it outside with a car cover (!) - not happening.

This is my 2nd Prius, I traded in my 2011 for the 2016 Prius Gen4 - bought new in 2016, now has about 25,000 miles on it. I'm retired and don't drive much, obviously. House & garage has a west exposure, 2 car...

I recently lost one of my key fobs for my 2017 Toyota Prius and need to program a new spare. I bought an Autel MaxiIM KM100 for the job, but I've run into a bit of a roadblock.

When I tried to program the new key, the device asked for a PIN code (or outcode/incode). I'm a bit stuck here—how or where can I get this PIN code? Does the KM100 have a built-in function to bypass/calculate it for this year, or do I need to get it from a third-party service?

If anyone has...

Maybe it's my imagination but the car seems to be getting worse MPG since that oil change.

1. The "Ready Mode" Trick: If you are car camping or want to keep the cooler running during a long stop, you can leave the Prius turned on in Ready Mode (parking brake engaged). The car will run cleanly off the large hybrid battery, and the gas engine will only cycle on occasionally for a few minutes to top off the battery, consuming very little fuel over...
