In the UK, Toyotas come with 1 year Toyota Roadside Assist, which can be renewed on expiry for £66 per annum by direct debit, £70 per annum by credit/debit card or £6 per month (£72 per annum). See https://www.toyota.co.uk/owners-info/roadside-assistance I would imagine that the Toyota importer in your country will have something similar to offer.

Just a "Final Word of Thanks" to those have wished me farewell ! Great forum this one no question about it !

That sounds about right - I would also ensure that the drive shaft seals are replaced at the same time. This will add a further £30 or so but shouldn't increase the labour charge.

You need a new battery, it's dead/flat, and I am amazed that you haven't experienced any other symptoms such as slow door locks, failed to unlock doors or failed attempts to switch on to Ready along with the triangle /!\ of doom? A brand new 12V battery fully charged should read 12.8V to 13.1V. The slightly higher voltage is the surface voltage immediately after switching off the charger and this will drop off after the battery rests. With the car in Ready that is showing that the battery charging via the DC-to-DC convertor is working at 13.4V.

And you found the reading was less than 10v on a 12v battery. What do you think you should do? I personally would change the 12v. We've mentioned that a 12v below 11.5v will cause bizarre issues. You can choose to ignore that and continue to suffer issues. You asked a question on the forum, we've mostly suggested a failing 12v and that it should be replaced. You've found it is indeed a failing 12v and yet still ask what to do? Using a Prius with a failing 12v will cause poor fuel economy and can put strain on the charging circuits possibly leading to expensive failure of those circuits. One cold morning you'll also find your 12v doesn't have enough power to start the car leaving you stranged - usually when you're in a rush and skint. Your call.

Neither the owners manual nor any brochure will provide the exact specification of your vehicle, so if you wish to continue discussions with Toyota, you will need some other proof, and I don't know what that would be, that your car should have been fitted with the automatic headlights feature.

If the Priuschat was up and running (they've had issues the last few days and have been offline) you could search literally hundreds of posts with alarm issues, abs lights, weird electrical errors and in 8/10 cases it's a failing 12v. It's always the first thing to check if the car is otherwise running normally. A good indication (though obviously not fool proof) is that the owners car is usually 5 or 6 years old or about 70k/80k miles and on it's original 12v. Also, the Prius 12v is very small and very 'weak' compared to a traditional car. In other words in can suffer a much shorter life if it has been allowed to discharge too low for too long. The Prius/Toyota hybrids don't top the 12v up with the same vigour as an alternator car does and thus if you do lots of short trips you maybe experience issues sooner. If you feel able get a multimeter and check the levels on the 12v in the morning after the car has been left over night. Anything under 12v needs topping. Anything under 11v is duff. Anything at 10.5v is lucky the car is running. If you're able and if applicable, remove the 12v and charge it with a car battery charge. Be VERY VERY VERY careful if you jump start the car. You CAN fry the electrics in a Prius if it's not done correctly! You may still be unlucky and actually have a fault on the car, but seriously if the car is 6 years old and/or over 80k miles on the original 12v, that is a good first place to look.

The B codes are are body related and will be your airbag issues, is your SRS warning light on ? as these codes would not set the VSC, ABS ligthts, if your SRS light is not then these codes should be ignored/cleared. C2300 & C2318 both relate to issues with the transmission park brake, if the park button is working as normal I would suggest your 12v battery is failing and setting issues with the transmission park brake actuator. Have your 12v battery/checked and replaced if required and the codes deleted afterwards.

First thing - Check your 12v, especially if it's the same one from new. Don't trust the internal computer. Get a multimeter and check it from the 12v battery itself. The car will give all sorts of weird and wonderful error messages and lights when the 12v is failing. People think their car is broken but in 8/10 times it's the 12v. If nothing else, it's a cheap fix and worth checking regardless. Oh and they cost about £90 fully fitted by Toyota. Non Toyota batteries are available but you may have to tinker with the vent hose. Search this Prius section for many many many other threads about failing 12v's.
