The Sirus/XM radio will work for a few minutes to a few hours then stops and the display says Check Satellite Antenna. AS we have had numerous other vehicles with satellite radio I know it is not a reception problem. Once the radio goes out it does not come back for several hours. This has been returned to the dealer once for repair, they replaced the satellite antenna. The Satellite radio went out and gave the check antenna message on the way home from the dealer after the repair. It is going back today for a second attempt at repair. This vehicle is also having a problem where the infotainment display goes out and shows random colors, reported on hear as a separate complaint.
