Curious what's been going on with your JGC so far?
Here's mine at 1850 miles, looks like a future service visit is in order
1. Faulty right park sensor (hit the bumper with my hand, it corrected it)
2. No volume on unit from Sirius, FM, ipod etc (restarted engine, volume worked again)
3. FCW came on, said clean sensor (wtf, it's perfectly clean - turned itself off in a minute)
4. QL goes to Off-road 1 by itself
5. I do hear my compressor on the QL "adjusting" itself more often, not sure how else to explain it?
