my 2010 is broken down

A follow up?

 

You'd be surprised, 12V battery failure is a very common occurrence in a new car. Sitting on a dealer lot, on a ship, being ported around is very hard on the battery, they become discharged, recharged, get jumped multiple times...

 

Doesn't matter, if it has a bad cell or something the issues could be very sporadic and unpredictable.

I had a bad cell in a brand new Toyota battery once. My symptoms included windshield wipers activating on their own...alternating headlamp failures. Weird stuff.

 

^ Make sure you document everything that happens (picture too). That way down the line if things get resolved you can send corporate a nasty gram or if they do not get resolved you can work the lemon-law route.

Sorry to hear about the problems.

 

Please bear with me, I need paragraphs:

There is a 'race condition' between pushing POWER and the car becoming READY. In fact, there is a brief READY, READY off, and READY along with a race condition where shifting into "N" fast enough can suppress engine start. But this is an area where we don't have a good mapping of vehicle states.

I will try to replicate various rapid shifts and POWER to see if I can replicate your symptom. This is not criticism but I have a distinct impression that this car works best if POWER is not rapidly followed by shifting operations.

Do you tend to drive in "normal", "Eco" or "Power" mode? This may impact timing during the POWER -> READY -> shift state.

Please understand there are intermittent problems that are highly dependent upon specific timing events. Finding a way to replicate these cases makes diagnosis possible.

Bob, thanks for your patience. When I see a big monolithic post, completely lacking paragraphs, I hit the Back button and move on. If people want help they should at least make a readable post.

I'm curious to know what the dealer found. Any update?

Thanks.

 

Oh my gosh, I'm so sorry to hear about what happened.
I hope this unfortunate happening won't scare you away from buying new Prius' in the future! Things happen, hopefully, this will be the only issue you have.

 

Fyi from the owners manual of the 2011 Lexus RX450h.
Rush the sequence and you go nowhere fast.
(New car in the parking lot, all $51k of it but I don't own it. I don't want to drive the Honda. Why do I always have to drive the Honda? )

Starting the hybrid system
Check that the parking brake is set.
Check that the shift lever is set in P.
Firmly depress the brake pedal.
The “POWER†switch indicator will turn green. If the indicator does not turn green, the hybrid system cannot be started.
Press the “POWER†switch.
After a while, the “READY†indicator comes on with a beep sound.
The vehicle can move when the “READY†indicator is on even if the engine is stopped.
Continue depressing the brake pedal until the hybrid system is completely started.
The hybrid system can be started from any mode.

 

Still trolling through the Lexus manual. Will put a tread in the Lexus section when I get more experience with its operation.

Your Toyota service center should have checked for a faulty "Power" switch or just replaced it under warranty. Weak battery or random interference affecting your wireless key? Cold weather slowed start system response and you just shifted into gear to fast?

Sounds like your dealers service department isn't as qualified as they should be.

If the hybrid system does not start
The immobilizer system may not have been deactivated. (→P. 117)

Operation of the “POWER” switch
When operating the “POWER” switch, one short, firm press is enough. If the switch is pressed improperly, the hybrid system may not start or the “POWER” switch mode may not change. It is not necessary to press and hold the switch.

Symptoms indicating a malfunction with the “POWER” switch
If the “POWER” switch seems to be operating somewhat differently than usual, such as the switch sticking slightly, there may be a malfunction. Contact your Lexus dealer immediately.

When the “POWER” switch indicator flashes in amber
The system may be malfunctioning. Have the vehicle inspected by your Lexus dealer immediately.

When the ambient temperature is low, such as during winter driving conditions
It may take time until the “READY” indicator comes on.

If the “READY” indicator does not come on when you press the “POWER” switch with the shift lever in P and the brake pedal depressed, contact your Lexus dealer immediately.

Emergency start function
When the hybrid system does not start, the following steps can be used as an interim measure to start the hybrid system if the “POWER” switch is functioning normally:
Set the parking brake.
Shift the shift lever to P.
Turn the “POWER” switch to ACCESSORY mode.
Press and hold the “POWER” switch for about 15 seconds while depressing the brake pedal firmly.
Even if the hybrid system can be started using the above steps, the system may be malfunctioning. Have the vehicle inspected by your Lexus dealer

 

My experience with a physically stuck shifter happened ~10 months earlier than yours however Toyota's SC "service" hasn't improved.

I suspect you tried enough times that whatever it was got unstuck.

The Evil Spirit that infested my car hasn't returned & I suspect yours won't either. Id keep Toyota's number handy as I told them that the next time it happens they are picking up the car.

 

One of the reasons why I installed a cutoff switch.

 

Many wierd gliches in electronics. Put in a cutoff switch, then rebooting is simple.

 

How did you do this?

 

How did you get it unstuck?

 

Sorry I did not see this. I bought a battery cut off switch at harbor freight for $4.00 and installed it in series with the battery ground wire. The type I got has a large red plastic key with it, to disconnect ( or reboot ) turn key and remove.:cheer2: OR: Was the question on rebooting?
