I loose xml signal when close to cell towers

My 2010 Nissan Frontier trucks oem XM radio looses XM signal when near to cell towers. The display shows that there is a channel but there is no audio, sometimes the radio will go to preview channel or show "no signal", non satellite signal works OK in areas near cell towers. I have rebooted the XM several times without any change . This issue appears to have started after the truck was rear-ended in a traffic accident.
