Prius died on freeway. 3 lug nuts missing, is this the cause?

The CM is an intermittent problem. I was having "outages" for about 2 years before Toyota announced this "enhanced" warranty last September. I lived with it due to the cost of having it done but once I found out that Toyota would cover the repair for free and provide a loaner car, I had the car repaired
I do not believe that a code is thrown. Once you have the battery replaced and, see what happens. However, Toyota WILL replace the CM if the customer states that there has been a problem. Good to know since you only have 2.5 months left to get this done!

 

To save a little money you might want to buy the battery and install it yourself. And you might want to check for alternatives to the OEM battery from Toyota. Searching here in Priuschat will give you lots of information.

 

As a temporary workaround, borrow a lug nut from a couple of the other wheels and make sure that the remaining four on each wheel are tight.

 

Interesting. So a previous owner put standard connectors on the car.
Make sure that the replacement battery matches dimensionally and will fit. It'll probably cost a little less (with the standard posts) but you should make sure that it's an AGM (absorbed glass mat) type, as that's what the car's designed for.

 

I suggest that it is time for you to seek professional assistance since you've replaced the 12V battery and the car still has a problem.

The fuel filter is located within the fuel tank. I don't hear MG1 trying to spin the engine in your video. It seems the problem is beyond a fuel injector issue.

 

The fuel filter is in the gas tank and is not available for inspection or replacement. Measure the fuel pressure in the gas line feed to the injectors to determine the availability of fuel.

I agree, at this point you definitely need to get it in to Toyota. Some things are just out of reach and can not be done at home in a timely manner. Keep us posted as to what they find.

 

Do you mean the catalytic converter? If yes, I do not see why that would prevent the engine from starting. I could see that a clogged catalytic converter might restrict exhaust gas flow and therefore engine power output, but the engine should at least start.

If you mean the inverter has failed (which contains a DC/DC converter) then I agree that your best bet is to have a used unit from a salvage yard installed, if your car is not covered under warranty.

 

You can get a salvaged Inverter for a more reasonable price. Contact Steve at: Plug In Hybrid Electric Vehicle PHEV to see if he has a tested one in stock.

Here are the pages from the warranty booklet for my 2009 Prius. It is ambiguous and confusing at the best. For the CARB states it just says "15 years or 150,000 miles, whichever occurs first" and nothing about the parts list. On the other hand for PA and WA it has a detailed parts list, including "Inverter with converter (footnote: Covered under the Hybrid System Warranty for eight years or 100,000 miles, whichever occurs first.)". So the questions are:
Is the parts list for the CARB states the same as that for PA and WA?
If yes, then for the CARB states is the inverter covered for only 8 yrs/100K miles as in PA and WA, or for 15 yrs/150K miles?

 

What does your booklet say with regards to the hybrid system warranty?
