Does 2005 Acura TSX have same Bluetooth battery drain problem as 2006 TSX Acuras?
Apparently so:
Acura dealers were sent a service bulletin in 2005 that said the HandsFreeLink systems can get “locked up” in an “on” position and the “system staying on may cause a dead or low battery while the vehicle’s ignition switch is off.” Dealers were told to replace the units with the same allegedly defective units, causing repeated trips to replace batteries once the problems reoccurred.
