During the coronavirus pandemic, Acura ILX 2017 car parked for four days and battery became dead even the battery was new (5 months old). This battery was a fourth new battery that the Acura dealer replaced for me during three years. Acura dealer knew the problem but they did not fix the root problem, only changed battery because car was still under warranty. Internet shows class action suit related to defect of hands free link bluetooth phone pairing system contains defect. The dealer did not replace bluetooth module even car is still under warranty. There were only youtube videos in the internet to disconnect bluetooth module for older Acura models.
