NHTSA Complaint #10556228 — 2010 CHEVROLET AVALANCHE

VEHICLE SUFFERS FROM EXCESSIVE FRONT/SIDE WINDOW FOGGING IN BELOW FREEZING TEMPERATURES AND THE MANUAL HVAC CONTROLS WILL NOT PERMIT THE USE OF A/C TO REMOVE THE HUMIDITY FROM THE CABIN. IN SUMMER MONTHS OR TEMPERATURES ABOVE FREEZING, THE A/C WILL ENGAGE WHEN THE FRONT WINDOW DEFROSTER IS ENABLED AND IS EFFECTIVE. WITH THE HVAC SYSTEM IN FULL DEFROST AND NO A/C, THE FOGGING ACTUALLY GETS WORSE AND VISIBILITY DECREASES TO THE POINT WHERE IT IS NO LONGER SAFE TO DRIVE AND WE HAVE HAD TO PULL OVER AND WIPE THE WINDSHIELD AND SIDE GLASS DOWN. THIS HAS HAPPENED 6 OR SO TIMES SINCE ACQUIRING THE VEHICLE NEW IN 2010. AN ATTEMPT TO HAVE THE DEALER RESOLVE IT WAS NOT SUCCESSFUL. *TR
