For me it’s going to be the KBD fender flares. I love the look but the stupid 3m tape keeps separating leaving gaps (if you have them you know what I mean). I’ve tried replacing it several times with different tapes, used adhesion promoter, etc but it still is separating.
I had this issue and they did replace the starter and the battery. 8k miles later it’s back but also shows up with the auto start/stop not restarting the engine. It’s been at the dealer for a month and they still haven’t figured it out.
I have the same problem with the added fun of no fluid going to the rear wiper. I haven’t taken it in to get checked yet but man that big pop up about low washer fluid every time I start gets awfully annoying
I had a similar problem on my dirt mountain bronco where the auto start stop wouldn’t turn the engine back on at traffic lights and then it would take several times to get it started again. Ended up being a bad battery and also needed a new starter; took two trips to the dealer to figure it...
