Why did my 2006 prius shut down while I was driving it

take the car for i dignosise

please have the trouble code read by anyone with a scanner,
ask your question again and include the trouble code,
I will be able to answer your question

Check the Horn Relay (in fuse box under the hood). You will need to check for Circuit continuity between the Relay and the horn button. There must be a loose connection under the dashboard or in steering column. Pressing the Horn button Grounds the circuit, so check the circuit from the relay to the horn button for continuity to ground.

Yes,the lock mechanism has either gone bad and needs replaced or is disconnected from the system.Whether it be accidentally disconnected while repairs being done or wire fell loose,pull the door panel and check it.If connected and has power when checked with a test light,it should work.If has power and no action,replace it.

Hello, first check the auxiliary battery in the trunk, if it's more than 4 years old it most likely needs to be replaced, this is a very common problem, if it's not the battery you'll need someone read the trouble codes in the computer, most autoparts stores do this at no charge.

Hello,
There is absolutely nothing wrong with your car. It's actually keeping you safe! If the outside ambient temperature is +37F or lower, your car knows this and gives a warning for possible black ice conditions. Lots of people wonder the same thing, next time it shows the warning, note the outside temp to see if it's below +37F.

I hope this info helps!

There is a 10 amp horn fuse either in your cabin fuse box or the engine compartment fuse box. If it is not the fuse, you will need to troubleshoot to find the cause. First, find the horn relay (usually in the engine compartment relay box) and pull it out. Have someone hold the horn button down while you push the relay back into it's socket. The relay should click as you push it in. If it clicks, your problem is probably in the wiring to the horns. You'll have to trace the wires from the horns to the relay box to see if the connector went bad or what happened. If the relay doesn't click, you can try replacing the relay, but the problem may also be with the horn button. To troubleshoot the button, you need a 12 volt test light. You can get one for a few bucks at a parts store or WALMART auto tools isle.
Use the test light to interrogate the relay socket. Remove the relay from it's socket. connect the clip of your test light to the positive side of your battery and then probe all of the relay socket terminals while someone holds the horn button down. One of the terminals should turn the light on bright. Some of the terminals may light it dimly, but at most one will make it bright. If none makes it bright, your horn button is not working or the wire from the horn button to the relay box is cut. If you have questions, please let me know. If you want to understand the relay, see my post at http://www.fixya.com/cars/r6022358-relay_check

hows your battery?,for the engine, not the electric motor,Prius,normally dont have any quirky issues with electrics,and behave normally if the car batery is flat,ie...it will behave like any other car if the normal battery is flat or old,check by jumping,(fuse box under hood has terminal for + and put neg(black) on suspension bolt ) 3 each strut top.That should work to see if thats your problem

Your car is perfectly fine. Your dash dimmer is turned all the way down. Your dash dimmer automatically turns on with your headlights. You need to locate your dash dimmer and turn it up.( will be easy to locate with owners manual).

2005 was the last year of that Prius design. 2006 started a new design. 2006-2009 use the same tail light.
