Oil Warning Lights in Your Subaru | Hanson Subaru in Olympia, WA

Many other components that have their own oils. Your car is smart enough to tell you with a warning light if there's a problem with any of them!

Assuming you mean "at" oil temp, which means your automatic trans fluid is running hot. Shouldn't happen at start up. Potential causes:

1. your fluid level is perilously low. Check it.

2. your ATF is simply worn out. Recommended change of ATF is at 100k miles. For the light to go on immediately you'd have had to put on well beyond that without a change.

3. there is a fault with the system monitoring your ATF temperature. Usual culprit is a corroded or smashed (have you recently had any major service done on your engine?) wire or a blown sensor. Can be diagnosed with an advanced OBD-II reader or take it into the shop.

I am not a Suburu guy or even a mechanic. I work on my own cars (Honda's). I am a firm believer in YouTube. A quick search of YouTube came up with this video. It might help. It looks like you have a flashing trouble code. If you decode the diagnostic code you will find out exactly what is wrong. Good Luck.

Instructions on paper-
1. warm up engine/ bring to normal operating temperature
2. Turn ignition switch off.
3. turn ignition switch on
4. Start Engine
5. Drive car faster than 12 miles per hour ( hes around block- not sure amount of time required at this speed
6. stop vehicle
7. depress brake pedal ( hold during following sequence steps 8-14)
8. shift to first gear
9-10- turn ignition switch off, then turn back on. He says you don't turn off Engine.
11. Shift to 2nd gear
12. shift to 1st gear
13.shift to 3rd gear
14. shift to "D", Drive gear At this point watch the at oil temp light flashing .
It will tell you the trouble code. slow/ long flashes denote "tens", fast flashes are signal digits. Example- ==slow-flash (1)== then -fast flash-fast flash-fast flash-(3) = 10 + 3 = trouble code of 13. once you have your code, go to google, type in "AT oil temp light flashing fix" it will give you DTC Diagnostic trouble code /code problems. Video he referenced , or at least the creator :

4. Get battery checked as the draw down at start up may have thrown a false code. I've seen Volkswagen dash lights go bezerk with a low battery. Most auto part stores do this for free as well as run a free diagnostic test.

You should try not to drive the car until you can get it in somewhere. It can be a small problem/false alarm but if you are losing transmission fluid that can be quite serious if you keep running it. If you have a dipstick for your ATF you should check it, if it is not low you can probably breathe easier but you should still get it into a shop quickly just in case.
If you have AAA have them tow it to a shop. Never hurts to be cautious with an engine or transmission.

I had a diesel VW that the glowplug light would flash, brake lights not work, all over an issue with cruise control that was a recall.

First thing would be check dipstick levels

That happens, but it will usually throw more than one.

If it is the “AT OIL” light and it’s flashing at a cold start then you might be looking at a control module issue within the crappy CVT

1.Dude, the CVT is a sealed unit ... good luck finding a dipstick for the tranny 😆

2. He does not have an automatic transmission... it’s a CVT and you just don’t change the tranny fluid in a CVT , you simply throw the entire unit in the landfill

3. Heh heh an OBD-II won’t pick that up

Put a piece of tape over the light.

have you checked the oil level? I’ve heard Subarus can consume oil, I guess a characteristic of a boxer engine.

believe the OP was referring to the “AT Oil Temp” light , which has no correlation to the crankcase oil

Or the new OP is an ass and just screwing with us.

How many miles are on it and have you had all recommended service done yet? I have a 2016 Subaru Legacy. Haven't seen that issue yet.

Why? Best AWD in the business and very good safety for its class. What do you recommend?

In that class I'd stay with Toyota.
