NHTSA Complaint #10679598 — 2009 BUICK LACROSSE

WE HAVE EXPERIENCED MULTIPLE ELECTRICAL PROBLEMS WITH OUR 2009 BUICK LACROSSE. IT FIRST APPEARED AS A BAD BATTERY WHICH WAS REPLACED. USING THE IN-CAR DIGITAL READOUT, WE BEGAN TO SEE STRANGE VOLTAGE READINGS IN THE CAR. THE VOLTAGE WOULD SOME TIMES READ AS LOW AS 12.6 VOLTS AND THEN WOULD START A STEADY CLIMB UP TO 14.4 VOLTS. IT MIGHT STAY THAT WAY FOR HOURS OR MIGHT SLOWLY DROP TO THE LOW LEVEL. AT THE LOW LEVEL, WE HAVE NOTICED THAT MULTIPLE ITEMS LIKE THE SPEED CONTROL AND THE AIR CONDITIONING WOULD NOT WORK UNTIL THE VOLTAGE WAS AT THE HIGH LEVEL. WE HAVE HAD AN EPISODE WHERE THE LOW BEAM WOULD NOT OPERATE UNTIL I SWITCHED THE HIGH BEAM ON AND THEM SWITCHED TO LOW BEAM. WE HAVE RECEIVED THE RECALL NOTICED ON THAT ITEM. OTHER STRANGE THINGS ARE HAPPENING LIKE THE RADIO CHANGING STATIONS ON ITS OWN. THE PASSENGER SEAT INDICATOR READS FALSE AT TIMES WHEN TRAVELING. THE AIR BAG INDICATOR LIGHT READS OFF AND THE SEAT BELT INDICATOR READ UNLATCHED. AS WE CONTINUE TRAVELING, THE INDICATORS GO BACK TO THEIR NORMAL INDICATIONS. *TR
