2017 Subaru Legacy Electrical system Problems

“Bought my car in 2017 and I had my battery replaced 2.5 years later due to low battery, multiple jumpstarts, failure starting, and severe corrosion. The replacement battery was from the dealership and within 6 months it had severe corrosion. During service the corrosion was cleared, but returned by the time the next service was due. I was asked to pay $57 to clear the corrosion which I declined because I thought since I got the battery by the dealership they would do it for free. 2 services later (1 year) the dealership recommends battery service at $90 due to severe corrosion. …”

It was diagnosed as a wiring harness. It would take 1500 hours to repair. The vehicle was torn completely apart. I have attached photos. …”

“Key will not remove from ignition when stopped resulting having to leave car unlocked not sure if park is fully engaged in transmission runs battery down from key being left in a on position this is a known problem”

“I have reviewed multiple threads on the internet talking about issues with the key being stuck in the ignition after putting the vehicle in park. They all suggested contacting Subaru america and that there would be a free fix since it impacts safety of the vehicle (seems easy to steal when the key is stuck in the car for example). Subaru did not respond as anticipated and instead responded with a 'go talk to a dealer' which also is quoted to cost hundreds of dollars to fix a widespread problem. …”
