Hello all, I wanted to post about a problem that left my wife stranded in the Walmart parking lot. I will post the abridged problem and solution then go into details.

Car wouldn’t start, jump starting did nothing. Battery replacement did not help.
The main fuse in the under hood fuse box was blown. Replaced fuse car works normally now.


The details to those that are interested, I didn’t find anything on the forum web or YouTube that helped me diagnose.


Wife parked at Walmart to pick up groceries. Sat there listening to radio waiting for them to bring order out. Popped trunk, put down windo to sign. Went to restart and nothing. Also radio hvac locks and windows didn’t work. First inclination was bad battery since I didn’t know what all wasn’t working. She tried a battery booster that didn’t work. Neither did jumping the car from a running vehicle. Since I was at Walmart I replaced the battery since this one was 4 years old and figured it was worth a shot.

Got the vehicle towed home. I had to find out how to get the car in neutral to be towed. It is a detent in front of shifter under mat that you use a screwdriver to push straight down similar to picking a lock on a bedroom door.

Once at home I tried my other key fob, and looked for any obvious electrical woes. Got the multimeter out and I find the main fuse blown. It is a specialty fuse that you cannot find anywhere locally and I called 5 Subaru dealers none of which had Instock.

It is a bolt on fuse similar to a mega fuse you may be familiar with. It is a MIDI 125 amp stud mount or bolt on type. I ordered from dealer $10 each. I also found on amazon for $8 for two. Slightly different but I think will work. If you search amazon for MIDI 125 amp fuse and Subaru part number
82211AL120

I had two days of downtime waiting on this simple part. For $10 you all may want to order one and keep a 8mm open wrench and 10mm wrench in glove box with a spare fuse to save yourself the grief, tow job, and trouble shooting. I will try to add a picture of fuse.

Since my car is out of warranty I feared a trip to dealer was in my future. I was thankful I was able to determine problem and fix so cheaply and easily after getting the part. I wonder if the dealer would have “found” an more expensive problem other than a $10 fuse. Maybe a computer?https://parts.gillmansubarunorth.com...2211AL12A.html

My last comment is I wonder what caused the fuse to blow. It wasn’t overloaded on accessories. My guess is just random part failure. I guess time will tell. Hopefully this will help someone as I didn’t come up with anything when I searched my problem. I keep 3 spares and the two cheap wrenches tapped together in glove box. It’s a 10 min job if that. I’d say if your car won’t start and you have good battery and notice the navigation radio hvac and locks don’t work this could be your problem. Good luck!

I just had the same problem with my 2017 Outback. Searched the internet and came up empty until this post. Same exact deal radio, dome lights, windows didn’t work but...dash lights did work. Replaced battery, jumped it - no luck. Checked all the small fuses- no luck.

Ended up finally having it towed to the Dealership. Got a call this afternoon... cost to diagnose and replace the $10.00 fuse = $300.00. And have to wait 2 days for it to be delivered to the dealership as it is not ‘on hand’.

Just ordered 2 of these fuses on Amazon and will also keep in my glove compartment. REALLY frustrating problem.

Was it out of the blue or had you drained the battery a fair amount and then had the fuse blow when trying to start back up (as was apparently the case for the OP, which I suspect was waiting with the ignition in the ON position, which puts a large load on the battery). Either way though, this is pretty strange, I can't imagine how it could happen unless the fuse or something else was defective.

I know I've seen this topic pop up a couple times before, but pretty sure it was tied to a careless jump start or battery install.

I found one thread where there's no question as to the cause - failure to observe correct polarity:

I suspect this is behind many reports of a blown main fuse. Could also easily happen when jump starting (although I'd expect that would be quite a show), I think the vast majority of folks I've seen using jumper cables have displayed some degree of incompetence. A lithium jump pack, while not as reliable, is sooo much safer. Most have spark and polarity protection.

I've never seen the main fusible link blown without a reverse-polarity jump. Lightning strikes are about the only other cause I've heard of, and those are pretty rare.

Please be very careful with fuses from the internet.

Amazon and eBay have been completely overrun with dangerous counterfeit fuses.

At 2/$8 I kind of doubt they are the real deal.

I'm having this issue..went out to start..nothing. No light, bells, beeps...nothing. Changed battery, cleaned terminals...still nothing. Looked at main fuse...it is bad. Can't find one anywhere, had to order from Denver. I hope it fixes it.

That style of fuse actually is very common and can be bought at most auto parts stores.
Pretty stupid that a dealership wouldn't stock a common fuse.
Not true. I went to 4 different auto parts stores. We did finally find one at a dealership in SLC($25), and 2 in Denver Napa ($4).

Part number?... Please.
... is in the first post, at least as it relates to the thread topic, which is MY2015. The person you're responding to appears to have a 2012, and you have a 2019, neither of which appear to use that part number.

I encourage you to check parts.subaru.com yourself, but this appears to be the corresponding part number for your 2019: 82211AL12A
