This is kind of odd..
It will do this every once in awhile, for about the past week and 1/2 or so.
It only seems to do it when the car is sitting for awhile. (i.e. overnight)
If I park is and go in somewhere real quick or for a couple of hours, it never seems to do it.
Just as soon as I start the car, the spoiler deploys. And I cannot stop it.
Electrical problem?

 

I had a similar problem that turned out to be a bad battery. The spoiler deploying when I started it was the first sign and then at some point the car would not start until I charged the battery. Once I replaced the battery never had the spoiler deploy again until the car was going over 58mph or so.

 

You need a new battery.

 

I just think that it is feeling its oats in the morning like young bucks do.
The battery could cause this as well though.

 

That would make sense, since I just checked my battery and it is the OEM!!
oh my God! I didn't check that before.

 

In case you need further confirmation..... YOU NEED A NEW BATTERY!

At least you know now, before you are stranded at an inopportune time.

 

If you look at the wiring diagram, then you will understand why the spoiler will go up at low voltage.

 

Im searching for new a new battery.
What do you guys prefer, because I am lost.

 

This recent pole may help.

 

saw that, also saw another thread and got to looking at the Interstate MT-P 91

 

Yea... I think Deb Walker just went through this dilemma recently. There was a thread helping her through the decision.

 

Definately new battery. Just went through this recently.

 

Go for it.....

Here's a link to get $15 off the Interstate MTP-91 at Firestone:

Wow! thanks for all of the help guys. I ordered the Interstate MTP-91 at firestone last night, going to get it soon.

 

Battery is changed.
My BAS/ESP light came on, however?

 

1: turn on ignition, engine start

2: make sure steering wheel is at center.

3: turn steering all the way to left (lock)

4: turn steering all way to right (lock)

5: turn steering back to center.

light should go out

 

thank you!

 

That light went away after driving the car a little while.
I have noticed; 1.) my car starts quicker 2.) my spoiler comes up at 63mph now instead of 65mph {little detal, but noticeable for me }

 

I was going to say that if you drive the car out of your driveway and turn up the street the light goes away as mine did. But, I always wondered if it was truly "set" as intended. Has anybody who is smart with this electronic stuff got any ideas?
By the way you say your spoiler deploys 2 mph slower than it did, how do you know your speedo has not been reset?
I doubt it is true really, when accelerating it would be tough to say what the actual speed is when it goes up. Mine seems to deploy in a range, and sometimes pops up for no apparent reason.
The spoiler deploys when the voltage is low, a battery that is failing cannot hold a full charge and the charge that is does hold goes down due to internal loses. As the battery gets even weaker, the length of time required for the battery voltage to get to the point that the spoiler deploys upon start up would get shorter. Upon starting the car the generator (thats what the manual calls it) provides enough power to keep the spoiler down. At this point the lights will probably brighten and fade in time with the engine revs.
Thats when you get a new battery quick. If you think your battery is a bit weak now and you intend to drive it in the cold there is one word for that ........ don't.
