Battery not in the greatest shape just under 60% state of charge.

I've just noticed in the last couple of days that the red triangle just comes on for a second like a blip and the beep sound but then gone.

I used dr prius and there's no codes

I heard just the beep yesterday and thought it was the passenger airbag sensor bc I had some stuff in the seat but today I happened to be looking down and saw the triangle illuminate for just a split second and then...

Unfortunately, when it rains it pours. Both of our Gen 2 Priuses developed red triangles of death in the past week.

This thread is about a 2006 Gen 2 (I'm hoping to get one of them up and running before worrying about the second).

About 10 days ago, my wife was pulling away from our house when the red triangle, VSC light and warning light came up.

I've had 12 V batteries cause all sorts of issues before. I checked the voltage using the MFD and it was a little low (10.8 V or so)....

  • MFD display turns back on when the car is turned off.(attempted to be turned off)
  • The car beeps as if the key fob is still in the ignition.
  • The cars doors will not lock.
  • All of this creates a drain on the battery.
  • The battery reads less than 12 V with no load and 14.1 with a load
  • a new battery has been placed in the vehicle – AGM

What we are trying to figure out is whether the blackout can also affect shutting the car down and the door locks. For example, has anyone seen it cause the doors to lock unexpectedly right after unlocking?

We ran into a situation at the store where the display went out, and we could not fully shut the car off. We held down the...

I got the part out along with the bracket. Unfortunately, the top line/hose nut is stuck in there and the thread got stripped.

I got the part out by opening the other end of the line, and taking it along with the part.

At this point I want to replace it. The nut isn't coming out, so I'm looking for that entire line.

Anyone got a part number for it?

The fuse box housing was cracked from previous hood damage, so I picked up a replacement fuse box from a junkyard. I did not swap the actual fuse box electronics or connectors, only the plastic housing.

The process was simple. I unclipped all connectors from the damaged housing, slid everything out, and snapped it into the replacement housing. Everything went back exactly where it was....

I've recently started to notice an unusual behaviour in the energy monitor on the screen of my 2008 Prius.
I bought it in December 2024 but since then there was nothing to report about the hybrid system, until now.
Basically, as far as my experience with this car, there is always energy coming back and forth from the battery, but in my case it happens only when regenarating/recharging.
It all began almost right after I installed and Android stereo with...
