Weird Behavior when Starting the car....
So lately days have been getting colder and my F is behaving a bit weird. This issue may have happened on warmer days but it happens more frequent now. So issue is that the car takes a few tries before the push button actually works. Even if I depress the brake pedal the light stays orange instead of turning to green so I have to press it several times to start the car. Also at least one time the car actually begins to crank but it falls short, like it doesnt makes it through the full cranking sequence hence requiring a second shot......................................Is my button broken or is my battery dying?

It certainly sounds like your battery is dying given the extra power needed to start it during the cold weather change.

Does the brake pedal feel like a brick..??
If yes.. See here:
Strange Brake Pedal Feel on Start ups
If no.. likely the battery on its last leg..!!

YES!!!! I was going to mention it but I never though it was related. But yeah everytime this happens now that I think about it the pedal feels like a brick.

The brick pedal feeling has to be on the FIRST push...
If that's the case clean out your brake booster check valve or replace it..
Fairly inexpensive and a quick fix !!

battery is on the edge. You will have the car die sooner than later. You better get that battery replaced quick. I have a jump n go in my car just in case. Cant leave patients waiting !!

Is this covered under the powertrain? Im already at 58,600 miles so bumper to bumper is gone...... If not, how do I remove and clean this valve? All I know it located right on the booster and that I need to remove the vaccum line.... But how do I pull it out? Do I use brake parts cleaner spray?

If your handy with a screwdriver & pliers this should take you all of about 5 mins!!

Omg that looks so easy. I will try to clean it up first. If not I'll just replace it myself. Thank you very much Joe I really appreciate it! I'll probably do this thursday before eating turkey and pecan pie. Happy Thanksgiving everybody!

When your car actually starts, an early indicator is usually the speedo gauge does not do a full needle sweep left to right on start up..........this usually indicates the battery is dying.
It certainly sounds like your battery is dying given the extra power needed to start it during the cold weather change.

What year is your IS-F and is this the original battery?
