Malfunctioning Hybrid System.

[NitroExpress]

My wife just sent the attached photos from our <1000 mile Cruiser. I was hesitant buying a first year vehicle but we were in a bind for a car and I justified it by thinking that if anyone can do a hybrid properly, it should be Toyota. It still drives with no observable issue, so it’s headed to a dealer right now.

Anybody experience this?

Well, already done at the dealer. I’m not sure exactly what was stated, but they said there is no problem and to keep driving it. I’m not sure what to do when the machine says to take it to a dealer and the dealer says it’s fine…
So, consider it ignored for now. (The lights all cleared with no intervention)

You might think about charging up the 12v battery if you have a charger or checking to make sure the connections are tight. Seems like this may be a possible culprit to these warnings from others with the same issue.

Thank you! I tried to read through this forum for this particular problem and didn't find anything. Did you read about this issue here?

My Jeep does REALLY crazy stuff when the battery is low/dead.

Most probably the 12v low on voltage. Strangest system I've ever seen. Mine has done weird gage things on two or three occasions, yesterday being the most recent....... Had the rear hatch open for about 6 hours and it shouldn't have been an issue as I installed a light off switch. Went to close up the LC and the battery was flat, put a jump box on it, started it etc......... decided to trickle charge the battery while it was accessible.

Just put a meter to the 12v battery and it measured 12.4v.

Take a measurement at the under hood jump point.

12.3v at the under hood jump point.

That's about perfect.

I experienced the same thing. I had it in the garage with headlights off and only interior dome light while adding sound deadening material to door to fix a rattle. Battery died and I jump started it with solo jumpstart battery device and it cranked right up. However, it threw all of these codes (see picture). Billy basic OBD II scanner would not clear them. I brought it to the dealer and they cleared the codes and it worked perfect. Fast forward 4 weeks later and I worked on another door rattle. Same scenario. Battery quickly died from interior dome lights and I had to jumpstart again. Same fault codes. I’m not going back to the dealer again and ordered a Carista Pro OBD II scanner tool. Hopefully, it’s capable of resetting these codes. Otherwise another trip to the dealer. Forget overlanding and leaving say the rear hatch open to pull out gear unless you remember to turn off all interior dome lights and have a jumper set. It will be dead in minutes if you left the headlights on even a few minutes. How is this hybrid (with a massive battery pack) die so quickly? It’s pathetic. No way I would charge anything off the back 120V.

It's not thw hybrid battery system, it runs fine. It's the parasitic drain on the 12v side. I complained to the dealer that If I didn't drive it for a week the battery would go flat, he stated " no way, it should last a month". I installed a digital voltage gauge by the 12v battery and when the voltage drops to 12v (vs 12+) I hook up my C-Tek charger. I ordered a solar charger that I plan on permanently mounting on the roof, that'll solve the low battery issue.
