Toyota Prius Electrical and Lighting Questions

    Hi Viking,

    yup - I know that. But since the Xenon bulbs/burners are supposed to last for the life of the car, a slightly premature failure would probably occur beyond the warranty period - and thus be a nasty surprise.

    OT: Sometime one might wonder how many modern cars are designed: The Mercedes "A" Class (not sold in the US) requires the front bumper to be removed to replace the side marker light bulb - and these burn out quite frequently. Cost of bulb: EUR 1.50. Cost of removal/replacement of front bumper: EUR 295 !

    Last night, pulled up and put my 2006 Prius in park and then depressed the power button. Got a little warm in the car and I wanted to open the windows; depressed the power button, cracked all four of the windows and depressed the power button again. Left the car, took the smart key with me...everything was 'off' as far as I could tell...All seemed fine until I got ready to acutally start the car and leave the store. Got into the car, fastened the seat belt, foot on the brake, depressed the power button...all of the shift position lights started to flash, the gas indicated went down to only having one bar (yet the car was over 3/4 full), the low tire pressure and ABS lights came on along with the check engine light. The park indicator light was green and the power indicator light was amber. I thought maybe I depressed the power button too fast, so I did it again only slower. Still nothing but flashing lights and then eventually no lights at all. I was able to put up all of the windows except the drivers (auto) window, thank goodness it was only 'cracked.' Finally called roadside assistance and had someone 'jump' the 12V battery in the front. After the car 'started' the red triangle with the exclamation point in the center on the dash board was illuminated. Also, the computer screen was only showing the lower 2/ the upper third in the left hand corner was (in red) an outline of a car with another exclamation point. I drove the car home; approximately 20 miles and backed into the garage (in case it had to be jump started again)...about 10 minutes later, went back out into the car and it started like there had never been any issues. Got up this morning and again no issues...called the dealer, they want to check for 'battery power' on Friday...this is not a good situation when you're alone hoping that your cell phone battery will hold up long enough to get some help.

    Can anyone assist me in removing the coverof the fuse box. I have been able to release the clips at the top of the lid, but cannot get the bottom clip to let go. I would like to be able to get to the charging post,inside this box before I really need it. Thanks Clem.
  • Twice in the last 2 weeks when I go to start our 2004 Prius, I step on the brake, push the "Power" button and all the dashboard warning lights come on, but nothing will happen. The car really isn't 'started'. You can't put it in gear. Pushing the "Power" button again does nothing, pushing the "Park" button does nothing. I tried inserting the key in the slot, and it went it, but nothing happened, and then the key could not be removed. After letting the car sit for awhile (10-15 minutes), I stepped on the brake and pushed the "Power" button and everything shut down. Then it would start as usual, and the key would come out.

    Called the local dealer service manager who said that they would have to get the car to do the same thing in order to diagnose the problem. He says there would be no computer codes in the system that could help. I find that hard to believe.

    Any help would be most appreciated.

    I have a 2006 Prius with almost the same problem. Not only do both headlights occasionally go out and come right back on when I flick the switch, but sometimes the left light, sometimes the right goes out until I turn lights off and on again. I told my dealer about this months ago, but they said I neede a new left headlamp, apparently ignoring everything else I told them. I can't believe it's either or both of the lamps themselves--it looks like a problem with the circuitry, maybe the controller card that nw_viking mentions. I'm going to take it back to the dealer, but if anyone has found a solution to this problem, I'd be grateful to know, too.
  • I had this same problem, got pulled over probably four times because my headlights were intermittently on or off so I would check before leaving and they would be on, next thing I know I was pulled over, flipping the switch on off to reset lights and cops never ticketed me, however, I finally brought it to my dealer in VT because all my lights (dash and exterior) went off while driving at night once and scared the ...out of me. They changed the HID bulbs and the "casing" for the drivers side bulb free of charge...I have not had this problem since. This was occuring at around a year or so after buying the car, now I have almost 100k miles and have not had ONE problem at all I love this car. Just another quick note, I did send a letter to Toyota based on the scare of all my lights going out while driving 55 mph at night and did receive an appology letter and compensation for my troubles.

    Thanks. Very helpful. I've had the same experience with the local police. I've never had the interior lights go off, but both headlights have gone off twice when I was going down some very steep mountains, and I had the dot dot dots scared out of me, too.
  • I want to connect a 1000w inverter to the 12v battery, but am having a difficult time removing the red protective cover on the + terminal. also, could I connect to the terminals under the hood that are used to jumpstart ?
  • I failed to mention I have a 2005 Prius, In the above post. Thanks
  • TOYOTA CALLED AND SAID THEY WILL PAY THE DEALER DIRECTLY AND THERE WILL BE NO OUT OF POCKET COST TO ME!!!!! ----- I have a 2007 Prius with 42k miles on it. My headlights have been going on and off for a while now. I recently got a fix it ticket in California so I took the car to the dealer. Guess what? Not under warranty! Both HID lights need to be replaced for a total of $450. I left the car at the dealer and called Toyota at 800-3331-4331. They opened a case file for me. The next day a case worker called me and told me that they would pay the parts and I would cover the labor. (they would reimburse me) I told her I did not have the $450 and would have to wait to do the repair. She told me she would check to see if they could pay the dealer directly and call me back. Within a few minutes, the dealer called me and said Toyota is paying for the repair and my car will be ready tomorrow. Right after that TOYOTA CALLED AND SAID THEY WILL PAY THE DEALER DIRECTLY AND THERE WILL BE NO OUT OF POCKET COST TO ME!!!!! I still love my Prius! Toyota came thru for me. I was ready for a fight, but did not have to at all!
  • 2005 Prius, no problems that were not a simple misunderstanding so far. Until about ten days ago when I left an interior light on when the vehicle was snowed in for a few days. Then the battery was dead which is understandable but I have not been able to get things going again which is not. My attempts to jump the vehicle have all been in vain. I have been locked out but managed to get back in with the stump key in the fob but no matter how long I charge it from another vehicle, the battery seems to be dead. No action, nothing. Any suggestions? Also, I got the vehicle used and there was only one key or should I say electrical starting mechanism. Any way to get another without paying three hundred dollars or more?

    Same thing happens to my 2005 Prius. Twice, I had to have the 12 volt charged. Dealer said the battery was fine.
    The other day, in a grocery parking lot, I tried to start the car and all of the lights flashed and I could not get FOB out. Waited and pressed power button and car powered off. Started again and it was fine. It seems that it had to recycle or something.
    Today, when starting I felt the brake push against me and the triangle flashed on for a moment. I pressed the power again with light touch on brake and it started. Seems many people have same or similar problem but no Toyota dealer seems to have ever heard of this!
    Anyone else with same problem?

    My'07 had one headlight go out. I took it in to the dealer and the service writer all but admitted defeat. Saying, "well, we probably don't stock the HID bulbs", and "we will need you to leave your car to diagnose such a complicated system". I took it back and explained that the "outage" was intermittent. And that the light would fail if it was left on for about 5mins. Anyway, I got my car back and they were "unable to duplicate". By the time I reached the end of their driveway the light was again out. So I took it back AGAIN and they were able to replace the bulb.
    What are they going to do when something goes wrong on my car that is more complicated than a light bulb?
    It causes my head to hurt when I think about it.
    Incidentally, the armrest on the driver's door is broken under the upholstery. They removed the door panel to check it out. I had to return for the "factory man" to rule on the repair. They took the door panel off and examined it and said it was not covered by the warranty.
    They didn't put the panel on right and my triangular speaker fell off.
    The rear bumper cover is pooched out on the side and was never right from delivery.
    It is not clipped into the proper tab and is bowed out. I had to return when the "factory man" was in town again. The "factory man" ruled it was not covered since it was past the "adjustment period".
    It seems they are better at declining repairs than at actually repairing cars.
    I have never met, nor even seen the "factory man". I am not sure he even exists.
    Now, the coloring on the leather seat cover is coming off. I am concerned I will have to repeat the same kangaroo process.

  • There are HUGE differences between Toyota dealership service centers.

    Sounds like you got one like Gosch Auto in Hemet, CA.

    That's where I got my Prius.

    Great car, bad dealer to make many long stories short.

    On the highway a couple months ago my super '04 gave a little jolt and the cruise control popped off and wouldn't reengage. The triangle with the exclamation point, the engine with the half circles around it, and the engine with "check" warning lights came on at the same time. I called a Toyota garage who said "bring it in", and hadn't heard of this before. I then called Toyota regional and asked them. The guy said "nothing important, it'll be okay next time you drive. Just a minor glitch." Whoa!. Next day the lights were still on, but the cruise control reengaged on the first try. After a few miles the three warning lights went off. Frugal me didn't bring the car in.

    Yesterday it happened again. However, this time both the cruise control AND the A/C compressor went off and stayed off. (Its 90 plus in Sacramento today). The fan kept fanning. All else is fine. Anybody heard of this one, and if "yes", what was the fix?

    My experience with the Sylvania Silverstar replacement headlight bulbs was somewhat less satisfactory. I put them in my '02 VW Passat, and was somewhat pleased at first. They were NOT the difference between "night and day", but they "seemed" a little brighter/whiter to me.
    Several months passed, then one headlight failed. I tried to replace the bulb, but was surprised to find the female electrical connector had melted and fused together with the bulb itself. As a matter of fact, the wiring was melted back about an inch from the connector and the insulation was GONE.
    Since I was unable to "unplug" the bulb from the connector, I was dismayed to find that VW offered only a COMPLETE headlight [non-permissible content removed]'y ( $$$ ) as a replacement part for the melted wiring and connector.
    Fortunately, my experience as a M-B mechanic provided me with a safe and reasonable "way out". I ordered replacement connectors from the M-B parts department and repaired the melted wiring on BOTH headlights.
    I now have "normal", factory headlight bulbs back again in my VW and hope never to forget the lesson life has taught me concerning "super duper" replacement light
    My '07 Prius ( pkg #6 ) came equipped w/HIDs and I have had to replace only 1 headlight bulb ( under warranty, 3 trips to the ?Service? Department ), so far.
    Incidentally, my 30yrs experience as a M-B mechanic also taught me that the ML :lemon: was, at the time, the very worst vehicle that M-B ever produced for sale in the US.
    That vehicle has been superceded by the W211 E-Class :lemon: as the very, very worst Mercedes-Benz EVER produced for US clients/customers!
