Just wait till the dash starts shutting off randomly or you get a million DIC errors. You'll really love that PAC then, lol
They don't all fail, cause weird data issues and die horribly. Just most of them.
Don't take my word for it, though. If you're on the fb groups, search "dash lights off" and there's dozens of posts with aftermarket stereos and similar problems.
The parking breaks stick sometimes. Doubt that would cause a leak. Throw on a new level sensor, give it a whirl. They're like $12 bucks local.
