Brought a new max ltd home yesterday. Rode it for 30 mins or so and got a pinhole leak in back passenger side tire. Had stuff to do so just parked it for the evening. This morning i fixed the tire, cut it on, hooked up a 12v air compressor, turned on the radio, and proceeded to put air in the tire. Drove it up the road and back and while i was out the check engine light came on and the lcd read check dps. Since then the power steering is out and the check dps and engine light has remained on. Called dealer, they recommended to try charging the battery as that often happens with low battery. Going to try that tomorrow, but i just have a hard time beleiving a brand new battery would get drained from a 12v compressor and the radio playing. Never had a sxs before, is this common? Did i do something wrong?
