Same here. I have never understood ramping a high clearance vehicle for an oil change. When i rotate, getting the back end on stands looks easy. Not sure about the front yet. Probably one corner at a time like my Silverado.
The sound is real. I caught it the other night and went into full alarm mode. I started and stopped the engine to make it stop then looked it up online. Evap system test. I dont like that kind of load on my idle battery. No gas smell yet.
