3) The exclamation mark/warning on the left side of the steering wheel is on. The dealership told me that its because of the tire pressure change due to the prep before being sold. They said it will go away after the car settles.
Get one of those electronic tire pressure gauges. Should run about $10. Then inflate your tires to the settings on the inside of the door. I had this problem when I first got the car. The problem was the pressure was on the line causing the system to trip. Properly inflating the tires solved it.
4) The car has slight hiccups. VERY slight - the average driver wouldn't notice. But basically, at a stop sign, every few second..you can feel a slight jerk of the engine. very slight. Is this normal? Like i said, nobody would notice this as it is very slight.
My 2004 has this same problem. The dealer thinks I am making it up.
5) I noticed road rash on my wheels. I didn't see them until the day after I took my car for a wash. Could that have been the cause? I have taken all my cars to this place, and have never had a problem. Is it because the wheels are larger than 17?
I run my car through a drive through wash 3+ times a week on average. My rims have some rash to them, likely caused by this. The tires don't stick out farm from the rims, so it's reasonable they were scuffed during the wash. I don't concern myself with this.
