My '05 Mustang is cycling the automatic door locks while I'm driving!!? This just started and it seems like it

Question

My '05 Mustang is cycling the automatic door locks while I'm driving!!? This just started and it seems like it's more often when the car is cold. I live in Chicago. At first I thought it was when I was turning but now it's happening while I'm driving straight down the road. Has anyone heard of this or know what i can do before I end up back at the dealership. The warranty has expired!!
Thanks Dave

I got a reply from mymustangsite forum that suggested the remote may be faulty. The trunk popped yesterday while my wife was driving, so I will change remotes and see if that's it.

Answer 1

It sounds to me like you might need to reprogram your "autolock" feature.
You can try to just deactivate it & then reactivate it.
To do so, follow the directions in your owners manual (page 65)
If you don't have a manual you can download it (free, courtesy of Fords website) by clicking the link provided below:
http://www.motorcraftservice.com/pubs/content/~WO5MUS/~MUS~LEN/42/05musog3e.pdf
This digital version of your manual is in pdf format so it is easy to download & save to your computer.

If you don't want the entire manual ... I'll copy the directions for you:
************copy of page 65*********
Autolock (if equipped)
On vehicles equipped with an automatic transmission, this feature
automatically locks all vehicle doors when:
• all doors are closed,
• the ignition is in the 3 (ON) position,
• the brake is pressed before reaching 5 mph (8 km/h), and
• then the vehicle increases to more than 5 mph (8 km/h).
Relock
The autolock feature repeats when:
• an “autolock” occurrence has already taken place,
• the brake is depressed while vehicle speed is less than 5 mph (8 km/h),
• any vehicle door is opened and then all doors become closed again,
and
• then the vehicle increases to more than 5 mph (8 km/h).
Deactivating/activating the autolock feature
Before following the procedure, make sure that the ignition is in the 1
(OFF/LOCK) position and all vehicle doors are closed.
You must complete Steps 1-7 within 30 seconds or the procedure will
have to be repeated. If the procedure needs to be repeated, you must
wait 30 seconds.
1. Turn the ignition to the 3 (ON) position.
2. Press the power door unlock control three times.
3. Turn the ignition from the 3 (ON) to the 1 (OFF/LOCK) position.
4. Press the power door unlock control three times.
5. Turn the ignition back to the 3 (ON) position. The horn will chirp.
6. Press the unlock control, then press the lock control. The horn will
chirp once if autolock was deactivated or twice (one short and one long
chirp) if autolock was activated.
7. Turn the ignition to the 1 (OFF/LOCK) position. The horn will chirp
once to confirm the procedure is complete.

I hope this helps, if not, you may have to make that trip to the dealer after all.
;'-)

Answer 2

You might have a loose ground or connection somewhere. Do you have an aftermarket alarm installed? They cause those sorts of problems some times.

Answer 3

Isn't it still under warranty? take it to the dealership

Answer 4

Why the hell did you buy a mustang in the first place! 69 Mustang i can understand but 05 Mustang is a pile of shite and does not go around corners.

Trade it in and get an old one, Go on you know it makes sense!
