HAZARD KEEP FLASHIN FOR NO REASON

SOURCE: Hazard warning lights come on intermittently

your mechanic has only given you part of a possible solution...lock the car with the key and hold over for 30 secs then take key out,wait 30 secs then unlock/hold key over for 30 secs,the windows may go down. then use the remote to lock car holding down the button for 30 secs..... this resets the system

SOURCE: hazard lights wont stop flashing and car wont turn over.

unlock driver door twice consecutively because that's how u disarm the car alarm.As for the radio, input the code that's in ur booklet. If u don't have it, call ur local dealer with the car's serial number and they will give u the radio code. It's 4 digits.

I have a 97 subaru outback and encountered the same problem. It is a security device on all newer subaru's. After changing or charging the battery, leave the negetive battery cable disconnected. Turn the key to the "on" position, then reconnect the negative terminal. This will stop the flashing.

SOURCE: hazard lights flash by themselves, doors won't stay locked (unlock by themselves) key fob won't work.

I has a similar problem and I just took the battery out of my remote. I think there is a problem/ short in the remote. It's as if the button is being pressed when it is not. I will use my spare one in the mean time. It was driving me crazy becuase I was driving long distance at the time and when I removed the battery it stopped. I hope this works for you!
