300 miles and lost all the presets and the XM radio de-activated this morning. All I got was channel 1 on XM. I had to reactivate it. I did that online instead of calling XM. I used the remote start so I did not know if it cranked slowly (was not out there!). It has been -10 degrees F around here lately (daily high temp!). I do not do short drives in this type of weather in any of my cars. So, the battery should be charged fine by the charging system. My car is in the garage all the time. I will start manually from now on to see how it cranks. The car came with remote start and the extra security system (perimeter) and I had dealer install XM. I have had the car 1.5 weeks so far! I had all the stations set, 1 am, 2 fm and 3 sat (XM). That sucks. This is the first time I had this happen without having the battery disconnected for service. This has happened on my first junkie cars but none of my new ones in the last 5+ years.
