C'mon people-somebody must have a clue as to where I might start trying to find out why this thing is acting this way. There has to be someone out there smarter than me. Thanks for any input. Russ 41.

I had the same situation on my '07 HID Prius.
The NHTSA has investigated the claims of BOTH HID headlights failing while driving.
All they found was ONE light out at a time.
They closed their investigation.
I had an intermittently functioning R-H side ( passenger ) HID headlight.
I took it to the dealer when it was hot under the hood and they told me to come back so they could "diagnose" the HID system. They could 't get it to malfunction since the lot boy shut off the car after parking it on the lot. ( After I told the NOT to ).
So I picked up the car and before I reached the edge of their driveway, the light was out.
Anyway, I took it back to them ( 3rd time ) and they replaced the HID "burner" ( bulb ) under warranty.
They told me it was a $400 repair. The 1st service writer surrendered when I initially presented the car for repair. She said it was "probably a bulb, and they didn't stock that part". What a JOKE!
That was over a year ago, and so far everything is still going strong.

Thanks so much for the info. Not quite sure if I have the same situation. I don't think I have HID.-unless the car comes stock with them. In any case it isn't an intermittent problem. As long as the car is "on", the right light is out. If I turn the car "off" and cycle the headlite switch, they both come on. If I turn the car "on" with the lights on, the right one goes out. Sort of defies logic doesn't it?

Prius light problem by crockett96

I have a 2006 Prius. Had right headlight bulb replaced first year, and have been back to dealership 4 times for continued headlight problems. The light went off and after several trips to the dealer, they said we needed to replace the ballasts--extended warranty covered the $600 fee because we had gone past 36,000 miles.
Now the fog light and parking light are out on the left side and the lights go off and we can get them back on by flipping the switch. We don't think our dealer knows how to fix it--now they say replace all headlights at $200 each. Any suggestions from anyone? Crockett96

Find another dealer with a service department that knows the difference between its' butt, and a hole in the ground.
"You can't sell the second one, if you can't fix the first one."

Question re self-installation by crockett96

Does anyone know if it is okay to personally change out the fog lights in my 2006 Prius--the book says take it to the Dealer but as my previous posts show--they don't really fix anything, just continue to charge. I'm thinking I can do this myself and perhaps get the problem solved.

go to subject title: engine trouble....
 
I and others had this same issue as well about stalling on the freeway. There are a few things that I recently tired and what others tried as well.
1. Ask for a software upgrade ... should be able to do it under warranty or under 100k miles for free
 
2. Crankshaft Sensor...when the sensor gets hot or fails, sets off engine light and shuts down engine...something like that. I paid $390 for both of these installs...I have an '05 prius with 156k miles...so warranties don't apply.
 
I did a test run tonight and ran it for over an hour at 80mph. It hiccuped a few times during acceleration, but kept strong.
 
My problem is that my engine continues to run even at a dead stop...when it usually shuts down and secondly my fan for the battery (in the back seat) stays on and does not shut off. Dealer told me that my recharable battery is bad and also possibly the inverter...those are $4k a piece parts. So I tried the first top two.
 
See if any of these solves your issues...as for the battery and inverter...those should be covered up to 100k...so if your issue continues, opt for one or both of these to be replaced. Good luck!

That CAN'T be right. If the top speed is only 10mph, then no one would ever be able to get it anywhere w/o being flattened first. It is very, very difficult to believe that the dealer did not have the car towed in immediately. Very, VERY difficult.

Brake lights by jbvc

Anybody changed the brake light bulbs? I can't find them in my 2005 Prius. The owners manual is no help as is the Haynes repair manual. There doesn't seem to be any access to the brake lites in the aft cargo compartment. I can access the backup lites, tail lites and turn signals but not the brakes.

I am pretty sure the brake lights on my '07 are LEDs. I am not sure how one could ever replace them short of the entire tail light assembly being replaced.
It seems to me you might be on the wrong track. I see there is a recall on MY'04 Priui for a brake light switch that can be overcome by "silicone oxide corrosion".
The switch is to be replaced.
