Brand new to the game.....Just started modding a 2016 4door Rubi I bought used last year. Nothing fancy, just installed a Barricade front bumper that required relocating a vacuum canister welded to the front end. Post installation, I receive an aural buzz of about 20 seconds shortly after starting the engine. No other auras, and no lites. What’s up, bad vacuum generator (are they one and the same??), or bad line connections. Buzz stops on its own after brief duration. Jeep runs great otherwise, pre, during, and post buzz. Heading to Moab soon and I don’t need mechanical issues. Driver issues may prove to be another story
