1998 legacy and it random blinking lights by mgc98legacy

new to the forum, anyways i've got a 2.5 GT 1998 legacy that just recently began having the hazard lights, the dashboard, radio all start blinking when the car is off. I noticed that while this off the same clicking noise it makes off is also occuring while the car is running. the check engine light had been on, i had recently changed all the spark plugs, spark plug wire, and cooling system. The car runs fine with the check engine light on. I feel this is something to do with another aspect of the electronics system. any ideas??? i pulled the battery and put her to sleep for the night. thanks for any help!

I wonder if it could be an alarm or remote keyless system malfunction? Change the battery on the key fob, perhaps?

If you've still got te 2005 XT - you need to be very careful about the turbo. I have a 2005 Outback XT with 67K. I've been very good about changing oil and my turbo has now blown out. It's been in the shop for the last few days and I don't have a complete diagnosis yet, but I'm sure that it will be very expensive. Apparently there is a mesh screen in the banjo bolt that's in the turbo clogs and starves the engine of oil and bang - you've got a dead turbo on your hands. Looks like Subaru knows about the problem but hasn't been informing it's owners. Maybe this screen can be cleaned - if so it will save you much hassle. Just wanted you to be aware. I'll probably be posting more about my situation soon.

CEL 2003 Outback by cansub

This car has about 50,000 miles and I have owned it since new and had it dealer maintained. The CEL came on recently, and apart from now running rough for a few minutes when starting from cold it runs reasonably well. I take it into the dealer on Nov. 6, and having read all the horror stories about trial and error part replacement in order to get the light turned off, does anyone have advice as to how I can avoid this happening to me.
 
Any ideas as to what may be the problem.

if it's cat/con before 100,000 Subaru should replace it. Mine blew at 102,000 and they wouldn't touch it. My closest Subaru dealer is a snake so that's the last place I'll ever take it or buy from.

My 2001 Outback had check engine light on for some time. It ended up being the O2 sensor. Much cheaper than a catalytic converter.

2003 Outback - engine overheating by mburns01

I have a 2003 Outback with the 2.5L engine with 90k miles. At 75k the head gasket blew and based on other posts this issue is not uncommon. Now at 90k the engine keeps overheating when I go above 45 mph. I've had the radiator, water pump and thermostat changed based on my mechanics advice. Even after changing all these parts the engine is still overheating. The mechanic was stumped and called in Subaru and they said that they have seen some cases like this and that the engine is shot and needs to be replaced. I've never heard anything like this, the car idles and runs fine at slow speeds but once I start to cruise at speeds over 45 mph the engine will overheat. Has anyone else heard of a similar case?
