Red triangle of death help?

What are you using to pull the codes?

If not using Techstream or an advanced OBD2 reader, you won’t see all of the codes as there are hybrid specific ones.

Once you have the codes, we can probably be a bit better at providing support.

Since you just got the car back from an accident repair (or not had it back long), those possibilities of what the codes can be are large, but finite.

Good luck and keep us posted .

 

Doesn't the TOD also illuminate during the lower portion of a significant oil pressure fluctuation?

(how's that for complicating "check oil level" ?) Never hurts to verify.

Braking and oil lights have always stuck in my mind since my earlier days of racing with unbaffled oil pans. Lots and lots of sloshing around and uncovering of the suction screens.

 

If intermittent, probably electrical.

But tracing wires and connections can be a challenge.

I’d first look for the codes then research them. Even if intermittent, they will guide the next steps.

You could always look where repairs were done and see if there is anything obvious.

Good luck and keep us posted .

 

In other words, check your oli level in the engine.

 

I had a Jaguar 10 years back that got rear ended and when they put it back together, they put the brake line in a place it could rub .

Lost the brakes one night on the way home.

So things happen after accidents.

 

That usually means the engine was almost empty. Not good!
Keep a closer eye on oil levels.

 

I had to click on the OP's profile and look at some past posts to make sure.
But....this is "Gloria"?
The vehicle that was unfortunately in a wreck, had been defined as a total but you decided to keep. after discovering the body shop had ordered parts and was being instructed to repair it by the insurance company. You took the payment, but kept the vehicle and initiated repair on your own?

Ughh....

I know from past posts, you had a strong connection to the vehicle. But that's the risk with NOT simply walking away. The truth is, you now own a repaired vehicle that was in a significant accident.
I'm willing to go all out and simply say, the problems you are seeing today, are all related to the accident and repair. Either things were missed, or repairs are not complete or done correctly.
Will the body shop you dealt with back-up their work? Are they willing to look at again?

IMO the problem is your vehicle was in a significant accident. Which means the ENTIRE vehicle suffered a significant impact. Unfortunately, that can create visible damage, and also unseen damage. Which means your symptoms could be manifesting from nearly anything, simple to complicated. You basically have to try to track down the cause/symptoms, individually. Given the possibility of anything from structural damage to loose wires, I wouldn't venture a guess as to what may be causing your symptoms.

I would first seek help from the body shop that initiated repairs and was paid by you. They should be able to rule out some things it is NOT. That is check the suspension, frame, anything they did repair.

A few years ago, my Dad was in an accident, not his fault, and his vehicle suffered pretty extensive damage. The Insurance Company decided to repair as oppose to total.
When my Dad did get his vehicle back, the body shop had simply forgotten to do a LOT of things. They had forgotten to reconnect/repair his reverse camera, he was getting ABS messages, etc, etc,....
It took more than one trip back, to iron out all the problems. But since the accident wasn't his fault, and the Insurance Company was paying for full restoration...eventually..keeping fingers crossed, the problems did get ironed out.

I speculate, that is similarly what is happening here. I would guess, not everything has been restored to "right". It's just a daunting task now, to try to evaluate and track down what those things may be.
More challenging since you accepted payment, and these repairs are now being funded by you personally.

Good Luck, I hope you can track down the ghosts in the machine. And I hope repair is not too expensive. But since your vehicle is coming from what appeared to be a pretty severe accident situation, I wouldn't really venture to guess what may or may not be causing your symptoms. Other than you can be hopeful that it is loose wires, or cheaper/easier things to fix.

 

Solved in post 8. Low oil in engine.

 

LOL!
You know I read post 8.
But somehow thought the OP was being sarcastic. My own fault, I read into it.....
As in "Y' all freaking Brilliant..rolls eyes...Oil is low."

Oh well...that's probably a good resolution.

But you are right. Now the OP has to keep a close eye on his Oil Level.
Hope no engine damage was done.
Hope he doesn't have a leak that is causing significant engine oil loss.

But if it is/was just non-damaging low oil state?
Then hopefully the OP can get back to enjoying his Prius.

 

If it has been run low once low enough to where the light had to let him know, the oil pump lost prime and then lost lubrication.

It’ll now burn oil at a faster rate than before.

Checking this level frequently is important to avoid more damage.

 

Actually, oil pressure has zero to do with cylinder wear or oil consumption rates, except that low oil level is almost certainly a result of inadequately monitored oil loss, the typical concern with these engines is oil consumption itself.

The low oil pressure warnings which have already happened, as you suggest, have done damage. Just not to rings, pistons or cylinders. Those components are more often damaged by an overheating event than anything else, certainly dirty oil from inadequate maintenance, is another potential factor, but almost never the cause.

Loss of compression (ring tension or accelerated ring wear) is most commonly due to inadequately filtered intake air. The typical issues I have fixed related to uber-cr@ppy "will-fit" filters, installation errors of various types and poor filtration from "open" type filters. The second major cause is overheating, unfortunately the average buyer would have no way to know if that ever happened. Generally OEM software can ferret this information from the PCM, if it has not been tampered with.

 

No we all just open the hood and check the basics if there's any issues with the car.

You probably never check the oil and you have a Prius that eats oil. Most People on this site who have those 2 things going on usually end up buying a new motor. Lots and lots of blown G2 motors on this site because of no oil.

Since the oil was so low it threw a zero oil pressure TOD the engine usually incurs some damage. At the very least usually it will now turn into an oil eating little monster so you have to up the never open the hood thing. If damage extensive will soon start knocking.
