#23 of 105 Start Relay Motor
Jan 14, 2008 (10:25 am)
After turning on my 2002 Prius, 4 warning lights came on although the engne was running. I looked in the manual and it said to take to a Toyota dealer. The lights did not go off for a distance of 5-10 miles. I was told that they need to replace the start relay motor. Has anyone else had this problem and does this sound reasonable at a cost of $230 for parts & labor?
#24 of 105 Noise from gas engine

2004 Prius has started making a sreechy noise only when the gas engine is running. Maybe a belt or bearing? It seems too soon for these parts to be going. Any ideas?
#25 of 105 Car won't start
Sep 10, 2008 (6:09 pm)
I have a 2008 Prius with about 5200 miles. At times when the brakes were applied I had the sensation that the car accelerated. When I took the car in for initial service they could not duplicate the problem. I don't know if it is a coincidence but 2 weeks later my car would not start. When the power button was pushed the information screen came up but the car did not turn on. If I held the power button down for a 2nd time the warning lights came up for brakes, check engine, etc. The car would only shift into neutral. I started over several times but could not get the engine to start and it was towed to the dealer. I am awaiting a response, but if anyone has a similar problem I would appreciate your feedback. Really concerned !!!

The dealer can access the data in the computer and can tell if she had accidently put the car in nutral and steped on the gas to drive. This error is most likley driver error. The service sales department most likley did not inform her how to opperate the vechile and she should go back to her sales person to review with her how to opperate the car properley. The sales department sometimes goes a little quick and depends on service to pick up the slack. Mabey you should go with her just to be sure everything is explained properley just to remove all doubt. This is toyots most trouble free vechile. good luck

There may be hundreds of reasons just like any other vehicle on the road now. As always the first thing to check is if the gas cap is tightly screwed on. After that it could be the 02 sensors, cat converter, misfiring, bad fuel, etc. just like any other vehicle. The best solution is bring it into a Toyota dealer that can plugin a scanguage. When the check engine light comes on it 'throws a code' so that the tech can run down the problem.
When you get this info go onto a site like PriusChat and post the problem along with the 'code'. There are Master Techs and very smart people there that can give you straight info.

I have a 2003 prius. My lights have come on many times. I have to pay $80 just for them to test it and then what ever the cost is to fix it. I love the car, but I'm also frustrated with on much control the dealer has. The last time it went off, they said they "thought" it had something to do with the fuel line. It went off again 2 days later. I've owned the car 1 year, and the light has come on about 5 or 6 times. Good thing I bought a service contract.
#31 of 105 Computer problem??? 04 Prius
Dec 23, 2008 (7:35 am)
It's been very cold lately. A few evenings ago, after a long day shift, my wife came out and couldn't start our 04 Prius. All the dash warning lights came on and stayed on. The car would not go into any drive gear only Park & Neutral. She shut down the car, got out and had to lock the door manually as it would not respond to the keyless.
It was eventually towed to our mechanics - he diagnosed a frozen parking brake. Oddly, he had the same "problem" with his Prius that morning. A day later, on a cold morning, I couldn't get the car door to open with the "keyless." I opened it with the key and started up the car. All dash lights came on and the car would not go into any drive gear. I shut down the car got out, locked it with the key, went inside. Three minutes later I came out. The car responded to the "keyless" and started normally and drove normally. A day later I took it to our local dealership where they were "not able to duplicate the problem."
The diagnostic gave some various indications of a low 12v battery but the battery itself was strong. So, unless the dealer has the car hooked up to diagnostic and the problem occurs, I'm outta luck.
Service records show an ECM update was done on the car - we bought it used in 06.
#32 of 105 Engine starts then shuts down
Jan 21, 2009 (5:57 pm)
I have a 2002 Prius with 161,000 miles on it. It has been a great car. A problem I am having is when it is cold (below 32 degrees F) When I start the car in the morning it starts right up will run for about 10 to 15 seconds then shuts off and all warning lights come on. Then when I try to re-start the engine will not turn on for three more attempts but it will always start on the fourth try. Always! Then the car runs fine. The warning lights will remain on until the next day and then will go off, or I can turn the engine on and off four times and the warning lights go out always on the fourth restart. Any info would be greatly appreciated
