I bought an 05 TL 16 mos ago. One week ago, I started experiencing *slow* hard starts. The first 5 secs of *slow* cranking sounds like I have a weak battery. Then the engine starts.

I read that this could be related to the ULEV system. I also read in this forum that turning the ignition 2 clicks and waiting for the fuel gauge to fully register helps to lessen the problem. This has cut the *slow* cranking time to about 2-3 secs.

I have the same problem cold starting the car in the morning.

I also noticed yesterday that the clock is accurate when I turn the ignition 2 clicks, but when the car starts the clock always changes to 1:00, until the Navigation warning pops up. As soon as the warning flashes on, the clock resets to the correct time.

Has anyone else experienced these problems?

 

Low voltage will wreak havoc on the electronic in the car. I would replace the battery and see if the dealership will pay for the entire cost. I think Acura prorates the battery after two years.

 

Yeah, sounds like a possible battery problem. One of the cells might be bad or something and giving a low voltage. Have your battery checked.

 

Thanks for the replies.

I had a defective hands-free unit. It was slowly drawing volts from the battery. The draw was small so I didn't notice the effect on the battery because the car would start up in the morning and recharge while I drove.

In July I left the car in long term parking for 8 days. When I returned the battery was totally dead. The dealer replaced the hands-free system after they detected the draw.

The car has been fine until this current problem. In July I asked the dealer if the life of the battery would be shortened because of the handsfree defect. Of course, he said no.

Now I realize the battery life has very likely been shortened because of the handsfree defect. I think I will ask for a new battery using that argument.

I guess I should have figured out that this was a battery not a ULEV problem.

Has anyone gotten a free new battery based on this type of an argument? Thanks.

Thanks. Sounds good!
