My wifes car turned off by itself 3 times on her way to work this morning. I am a car stupid and would be thankfull for any help. Her car is a 2003 honda accord exl 4cyl with 100000 miles on it. All service is up to date.

 

Any warning lights? Does it just start right back up?

 

The dealership has a nifty tool that can let the technician observe PCM data the moments around a stall. This is of course it happens while the tech has it and the tech is smart enough to use it. Sounds like a bad connection or failing part. I've replaced main relays for this. Could be an ignition switch. Could be a bad connection from the battery to the fuse box. Could be so many things it's impossible to speculate without hoping to GUESS correctly. May have to bit the big one and pay the dealer to check it out.

Try to recall the exact conditions when the problem occured. Time of day, temperature, exact driving conditions ie. throttle position etc. It may help the technician and save you some cash.

 

so what the update on this, i have the same problem.

 

my guess would be fuse box under the dash i think that there is a recall on the car about complaining that car is stalling while driving but i am no pretty sure about the year you can go and ask to the dealer ship

 

Could be a number of things ranging from a bad ignition switch contact assembly to a faulty main relay to contaminated fuel.

We need a LOT more information before we can even begin to narrow it down. Did the Check Engine Light illuminate before the car shut down? Are there any Diagnostic Trouble Codes stored in the computer? I know you said that all maintenance is up to date, but have the spark plugs been replaced yet (Honda recommended service interval is 105,000mi)?

If you aren't particularly knowledgeable about cars at this point, it would probably be best left to a professional. As long as the problem occurs often enough that they can replicate it, they should be able to determine the proper repair.

 

Faulty oil pressure switch.

 

^no oil pressure had noting to do with this and this an electrical problem no a mechanical

 

Had the same type of problem some years back with my (at that time) Civic. It would shut down for no apparent reason quite erratically. Long and short of it....An oil pressure switch that senses oil pressure or lack thereof, shuts down the engine (turns off the ignition) Anyhow, my problem with "shuts off by itself" Why? Well no oil pressure=fried engine.Unless of course you shut down then engine (kill the ignition)
