2007 Acura TL electrical system problems

“The contact owns a 2007 Acura TL. The contact stated that the battery power was drained after driving the vehicle for less than 48-hours. No warning light was illuminated. The vehicle was taken to an independent mechanic, who determined that the Bluetooth in the vehicle was draining the battery. Bluetooth was disabled, but the failure recurred. The contact had since replaced the battery twice within two months, each time with the same brand of battery. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 90,000.”

“THE BATTERY DRAINS AFTER THE CAR SITS IN ONE SPOT FOR MORE THAN TWO DAYS. HAD TO BUY A NEW BATTERY. IT DID IT AGAIN. THE ALTERNATOR IS GOOD. BUT THE BATTERY KEEPS DRAINING. CAN'T AFFORD TO MISS WORK OR TAKING TIME TO GO GET THE BATTERY RECHARGED EVERY WEEK. THIS HAS BEEN GOING ON FOR A COUPLE OF MONTHS NOW.”

“OWNED THIS CAR SINCE NEW 12 YEARS AGO. BATTERY ALWAYS DRAINS IF NOT DRIVEN IN 7 DAYS OR SO. CONSTANT PROBLEM THROUGH 4 BATTERIES. JUST GOT A NEW BATTERY AND ALTERNATOR. CAR IS GARAGED. DIDN'T DRIVE IT FOR 10 DAYS. DEAD BATTERY AGAIN. BLOGS TELL ME THIS IS EXTREMELY COMMON WITH 2004-2008 ACURA TL SEDAN 6-CYL. BLOGS SAY IT IS THE HANDS FREE LINK OF BLUETOOTH THAT IS A CHRONIC DRAIN WHETHER OR NOT THE CAR IS RUNNING. SO I PARK IT IN AIRPORT PARKING, TAKE A TRIP, COME BACK AT MIDNIGHT, A WOMAN IN LONG-TERM AIRPORT PARKING, TOTALLY UNSAFE FOR ME, WAITING FOR HELP TO JUMP THE CAR. TOTALLY UNACCEPTABLE. NOT SAFE. YOU NEED TO DO SOMETHING! NEXT BLOCK SAYS "WHEN DID THIS HAPPEN" AND ASKS FOR A SPECIFIC DATE. I WILL USE TODAY' S DATE, BUT IT HAPPENS ANYTIME I DON'T DRIVE IT FOR 7 DAYS OR SO. THE BLOGGERS ALL HAVE THE SAME IDENTICAL SAME PROBLEM. THIS IS CHRONIC.”

“MY 2007 ACCURA TL HAS A BATTERY DRAIN PROBLEM. I HAVE A NEW INTERSTATE BATTERY IN IT. I PARK IT ON OUR DRIVEWAY AND AFTER 3-5 DAYS OF IT BEING PARKED, NOT DRIVEN, THE NEW BATTERY IS DRAINED OF POWER AND WILL NOT START THE VEHICLE. I HAVE TO CHARGE THE BATTERY. IT STARTS AND WILL CONTINUE TO START AS LONG AS I DRIVE IT TO RE-CHARGE THE BATTERY. THIS OCCURS VERY CONSISTENTLY AND HAS FOR THE PAST YEAR, ON AND OFF.”

“VEHICLE WON'T START AFTER NOT BEING USED FOR TWO DAYS OR MORE. IT'S BEEN NOTICED SINCE 2015. BATTERY WAS REPLACED 3 TIMES IN TEN MONTHS. IT'S A SAFETY HAZARD THAT ACURA SHOULD BE ADDRESSED/RECALLED. WENT TO MY CAR MECHANIC TO HAVE IT DIAGNOSED AND WAS TOLD IT'S THE VEHICLE'S HANDS FREE MODULE (BLUETOOTH) THAT'S BEEN CAUSING THE DRAIN. I CHECKED ONLINE AND FOUND OUT IT'S BEEN A MAJOR ISSUE ON THIS VEHICLE. HONDA/ACURA NEEDS TO RECALL THIS UNIT BEFORE IT CAUSES MAJOR ACCIDENT. IT IS A SAFETY ISSUE THAT SHOULD BE FIXED IMMEDIATELY.”

“I BOUGHT THE CAR YESTERDAY AND WHILE I SITTING IN THE CAR LOT, AFTER PURCHASE, I WAS SETTING UP THE RADIO AND HFL LINK. THIS TOOK MAYBE 10 MIN OR LESS. DURING THIS TIME A RELATIVELY NEW BATTERY WAS COMPLETELY DRAINED. THE HFL NEVER EVEN HINTED AT WORKING TO CONNECT TO BLUE TOOTH. I ALSO HAVE A 2005 ACURA TL THIS KEPT HAPPENING TO. THE DEALER RECENTLY TOLD ME IT'S A KNOWN PROBLEM, BUT NOT A RECALL SO INQOUKD HAVE TO PAY TO HAVE IT FIXED. SINCE IT WAS REALLY EXPENSIVE TO FIX HE SUGGESTED I JUST REMOVE THE HFL LINK. WHICH I DID FROM THE 2005 TL I HAVE. I HAVEN'T HAD A PROBLEM WITH THE BATTERY SINCE. NOW THIS SAME THING IS HAPPENING TO THE 2007. I'M JUST WONDERING HOW LONG IT WILL BE BEFORE I HAVE TO REPLACE THIS BRAND NEW BATTERY FROM THE HFL LINK DRAINING IT. I CAN'T LET THE CAR SIT FOR MORE THAN 3 DAYS OR IT WILL BE COMPLETELY DEAD. I WOULD LIKE TO HAVE BOTH MY 2005 AND 2007 HFL WORKING. THIS SEEMS TO BE AN ACURA PROBLEM AND NOT JUST FOR A FEW CARS.”
