NHTSA Complaint #10627819 — 2007 CHEVROLET AVALANCHE

THE ALARM SOUND FOR WARNING OF SEAT BELT UNBUCKLED, DOOR OPEN, KEYS IN IGNITION, ETC, IS GENERALLY INAUDIBLE. OCCASIONALLY IT DOES WORK, BUT USUALLY IT DOES NOT. IN 2010, THE DEALER SAID THIS WAS AN ISSUE WITH THE RADIO. MY WARRANTY HAD EXPIRED SO REPAIR WAS NO LONGER COVERED. I DID NOT HAVE THE PROBLEM REPAIRED DUE TO THE HIGH COST. I THOUGHT THAT THIS WAS AN ISOLATED INCIDENT UNTIL I JUST READ THAT THERE IS A RECALL FOR THIS EXACT PROBLEM IN LATER MODELS. - WHEN FUNCTIONAL, THE ALARM SOUND EMANATES ONLY FROM THE SPEAKER ON THE LEFT SIDE. I SWAPPED THE LEFT AND RIGHT SPEAKERS AND THE PROBLEM REMAINED, SUGGESTING THAT IT IS NOT A SPEAKER ISSUE. WHEN THE AUDIBLE ALARMS ARE DEAD, SO IS THE LEFT SIDE SOUND WHEN THE RADIO IS ON. *TR
