1 Alternator/generator/regulator problem

Failure Date: 07/21/2020

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.

2 Alternator/generator/regulator problem

Failure Date: 02/10/2019

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.
