parasitic drain on battery

Does anyone else have this problem? Have a 2007 Mustang (2 years old this month). Something is draining battery, and Ford dealership can't figure it out. Took it in 3 times now. If I let it sit a day and leave to go to work in the morning, the engine has a extended crank. I have disconnected the remote starts fuses, nothing. Ford gave me a new key(???), nothing. I even took it to my local repair shop last week and they don't see anything wrong with alternator/starter/battery. They think maybe it's a fuel pump problem.

Want to hear from others with same problem. Remote start isn't helping any if I have to physically go outside and start car first, then use remote start! That's kinda defeating the purpose!

Thanks!!

Yes, there have been problems with the amplifiers for the shaker system not turning off properly and draining the battery.

IF if it the shaker, what most folks do is just physically turn the radio/cd player off before opening the door. Sometimes when you open the door after the car is shut off, ( assuming you had the cd player on ) turns off the cd player but the amp still stays on.....

I always turn off radio when exiting the vehicle. So much, that my husband hates it when I do it in his truck. Thanks!

Update: rehooked up remote start on Wednesday. Car started fine on Thursday and Friday. Saturday afternoon and Sunday, car was very very sluggish. Maybe the remote is part of the problem, just don't think it's the whole problem.

Becky ,is the remote start an aftermarket item ? If it is an aftermarket item it may have been connected differently to a different power source causing the constant drain. Do you park your Mustang in the garage with keys left in ignition? We have an F150 and F350 at work that we leave the keys in the ignition and they both suffer from battery drain,the dealer said to pull the keys from the ignition when they are parked .You probably do not leave keys in car ,but it is another idea .Good luck!

Thanks for the message. I don't leave keys in car, but I could see how that would hurt it. And yes, the remote is an aftermarket item. I think Autoco East is tired of seeing me to pull fuses. Doing it again tomorrow. Crap, how I like a nice toasty car.

I've come across a similar problem with my 2005 Mustang. However, I believe I found my problem to be that the head unit (Shaker 1000 System) doesn't power off at all.

My battery was dead when I tried to go home from work. When I finally got it home, I went outside to get something out of the car and noticed the clock on the radio still being on. I removed the fuse and plan on taking it to the dealership in the morning, which from what I've read may be a waste of time.

This happened to me about 3 months ago as well. I stepped outside to go to work in the morning and the car wouldn't start. I had everything turned off but the battery was dead. I got the car jumped off, headed to work, and then when I got ready to go home it started fine. I had the battery tested and it came up fine. However, I'm not sure if this previous incident was caused by the radio problem I discovered today.

Sogwap55 is right...always be sure to turn off your radio before turning off the ignition.

Found out what my issue was. Apparently with the hard rain, some of it leaked inside and screwed up my fuse box. The dealership wanted almost $900 to fix everything. I'm hoping to plug the hole and let that be it. I really don't want to have to replace the fuse box & reprogram the car.

When I had to leave my car outside during a very heavy rain, I have had leakage from the window also. My windows are the type that roll down about a half inch when you open the car then roll back up when shut. (not sure what the 2005 model does.) Will have to remember that next time car is in shop to mention that also. Thanks!
