Exclamation Triangle, may need to replace HV battery?

welcome! your battery has a 10 year, 150,000 mile warranty. get the to a dealer for a fee replacement. are there no other dealers available?

 

i wish i could tell you that you can drive the car with no issues, but it's hard to say for sure.

 

Be ready to provide VIN.

Everything you report are classic symptoms of Hv Battery failure: dash lit up like xmas tree, no power, hearing battery cooling fan in back.

If the car has maintained registration in California or any CARB State registration since the very first owner (whoever that may be), and assuming this car is not a salvage title, you won the HV battery lotto. You have to get to a dealer, so they can confirm.

STOP driving the car immediately. Battery is getting weaker and can not help power the car to drive. There will be a point in time, in the IMMEDIATE NEAR FUTURE, the car will refuse to go, leaving you stranded. Get it towed to the Toyota dealership. Get a rental; maybe Toyota will cover the rental?

 

Yes, you will have no warranty whatsoever, and the manufacture has no legal obligation to provide any warranty coverage. There is nothing preventing the dealer from providing the warranty coverage to you and absorbing that cost, but this is unlikely.

Extensive water damage or repair costs coming close to 50% of the car's value at the time of the accident, usu cause insurance companies to write the car off. These cars then go off to auction.

You don't know if the current odometer reading is even correct. It is possible the original combination meter (speedometer, trip meter, P/R/N/D/B indicator) went bad and the rebuilder replaced it w/ a used one that had low mileage. Don't waste anytime wondering. It is what it is.

Since it seems you knowingly purchased a salvage vehicle, did you at least get it inspected, and what did this person look at?

To give you pricing perspective, a new OEM HV Battery pack can be had for $2071. A new OEM HV battery WILL OUTLAST any rebuilt battery from a scamlist (AKA Craigslist) rebuilder, or business such as Doorman or Fraudtech (AKA Greentech).

You can attempt module replacement for a few hundred, but don't expect great longevity. Some people have been fortunate to achieve longevity, but that is the exception.

The HV pack can always be transferred directly into another Gen2. Or transferred into a Gen3 by swapping all the modules from the Gen2 case into the Gen3 case.

 

A mechanical inspection is a good thing. But that's only half of the equation. A physical inspection (interior and exterior) looking for body work repair is the other half. Some body work is of such poor quality, that even a "blind" person could see it.

I would be concerned about the car's integrity. Salvagers make money at your expense. They have to buy the carcass, get parts (stolen or legally purchased), and fix the damage to be somewhat presentable. Many skip corners, b/c they want to make a profit. Doing proper repairs will eat into the profit.

Salvage repairs skimped, resulting in death.

For a fee, CarFax and VIN Audit could tell you the accident damage area and other things about any used car in question.

I would be concerned if the air bags are even functional. They could be wired to trick the computers to think there is a proper working airbag, where there may not be.

Hopefully you paid very little for this vehicle due to the salvage title.
