A call to all 05 LS owners, Any feedback is appreciated.
My 05 LS Ultimate is making this annoying electronic whine briefly when the tach hits 2500 rpm, The noise does not occur again until I restart the car. The dealer says its normal. So I was just wondering if other 05 LS owners have the same issue.
Dealer first said it was navigation system intializing.
A mechanic suggested it may the ABS system causing it.

Thanks
 
is it like a faint 1 second long beep (very faint)? my 03 does this.
 
I would not describe it as a beep,
definitely a electronic high pitch noise.
It's like a circuit being overloaded. I just wish it would blow
so they can find the problem.
 
Ken Motz's LS the exact same year, color and options as mine.
I wish he would respond to my email question.
 
OK maybe not a beep, almost the sound a crt TV makes (high pitched elec. sound)? Last's 1-2 seconds? mine does it too, I assumed it was airbags or seatbelt pretensioners arming. possible capictors charging up?
 
Hey "HR LINCOLN".....

I responded to your email? You must not have got it?

I took my Ultimate out after I got your email and I listened for beeps and tones and whines. Here is what I got.

I got a beep; "washer fluid low". And a "whine" from the cooling on the front seats. I ran every accessory and every mode and I listened for the whine you described.

This car has all sorts "beeps" and "cliks" and "tones"....but on this trip out I could not duplicate a tach related "whine or Beep"?

I can not duplicate it dude?

I was driving down the road the other day and I got a "beep" and there was nothing showing on the screen as being wrong?

These cars are known for "unknown" beeps and tones.

Does you car do it in park just sitting there? If it does, I'd have someone hold the throttle at 2500 while you look for the whine? Is it engine noise, an electronic generated sound or a mechanical sound.

The air boxes on these cars a a joke and you could be hearing some noise from the air box?
 
hrlincoln...I own a 05 Ultimate and get the EXACT same noise. It's really bugging me. I also took it in and the dealer said it was "normal". He said it had something to do with the THX navigation system and AdvanceTrac. It sounds like an electic generated noise on the drivers side coming from under the dash. (to me) But it only happens the first time I hit 2500 rpm. Once I turn the car off and back on, it will do it again. I hope there is a solution to this.

I've tried turning AdvanceTrac off from the button but that doesn't seem to help.
 
Wow ! Masterstyx described it perfectly.
I have a hunch it has something to do with the ABS intializing because sometimes you will hear a different noise coming from the brake pedal area around the same time.
I have requested the regional rep. ( zone rep.) to investigate this issue.
I'll let you guys know as more info becomes available on this mystery.
 
Service response

This is the response I got from FLM regarding the noise problem.

2003-2005 Lincoln LS - High frequency noise in the passenger compartment heard once per key cycle for 2 to 3 seconds.

Some 2003-2005 Lincoln LS vehicles equiped with advancetrac and a THX audio/navigation system may exhibit a high frequency noise in the passenger compartment for 2 to 3 seconds during the functional self-check of the advance trac system. This self-check happens once per key cycle the first time the engine reaches 2500 rpm or higher, with the vehicle speed between 15 and 55 mph, while not braking. This is a normal characteristic of the vehicle. So no repair should be attempted.
 
This sucks. How can I put motivate Lincoln to resolve this.
If enough people complain, will they fix the issue ?

Have you called the Lincoln Customer Service number? They MIGHT be able to help you but it is ultimately up to the dealer to fix the problem. Start talking with the Service Manager and then on to the General Manager. Work up the chain until you get some satisfaction but be civil about it. Don't demand to have it fixed just state you want your car fixed and leave as much emotion out of it as possible.
 
That's exactly what the dealer told me. The noise is REALLY annoying...I wish they could fix it. But at least it doesn't make the sound every time we hit 2500 RPM. Oh well...thanks for the update.

The problem is that Lincoln has said that there's no problem--it's a function of the design of the THX/Nav system. In other words, it's a design issue, not a faulty piece of hardware. The only way it could be resolved would be to go back to the engineers at Lincoln and have them redesign something to eliminate or mask the noise.

In short, Lincoln has said that this is the way the car is supposed to behave, so there is no problem to be fixed. This, in turn, means there's nothing the dealership can do.

I don't buy it. Someone in the Lincoln engineering group has to know about it or at least be told about it. That's why I suggested calling Lincoln. The special service anouncement, I believe, only gets broadcasted through all the service areas. I may not be correct. However, when I had a problem with my car the dealer could not figure out they got on the horn with the Ford engineers directly. I know this can be done at the dealer level. I'd ask if they have talked directly with the engineers about it.

Now, back in 2003 when we visited Lincoln at the Mania event we spoke with the engineers about problems that they were not aware of yet such as the mystery beeps. They could only explain it as a communication loss between the PCM and the component that shows the error. They said the problem can NOT be fixed. This may very well be one of those problems that can not be fixed but I would be making sure that the Ford engineers knew about it.

Don't just lay over dead with the issue. At least I wouldn't if it was my car.
 
I'll agree that it wouldn't hurt to call Lincoln, but I doubt that it would make any difference. I would be highly surprised if there were many (if any) engineers left in the LS program, given that it's a dead car. I know at least one of them is on his second post-LS program (and another is now the head of SVT :D ). They've also switched suppliers for the Nav system, so I doubt they'll spend any engineering time trying to resolve this.

The dealer's stuck--according to the message sent out by Ford (quoted above), the behavior is expected and "no repair should be attempted." That's a pretty flat statement...

Again, I don't agree with it and I would search more if it were my car. Maybe even call Pioneer and see if they have any answers. They made the first generation Navi system. They may know something. Keep asking questions.
 
I'm not saying you shouldn't pursue the resolution of this issue, I'm just saying that you shouldn't get your hopes up. It sounds like this is a problem that's endemic to the system (ie, a design flaw), which is not something that Lincoln will be in a hurry to fix. I particularly wouldn't get my hopes up with Lincoln, as they've already said that this is not a problem.

But, hey, go for it. What's the worst that could happen? They tell you to go buy a Cadillac? Like Ken said, be courteous but firm; maybe they'll do something about it.
 
I can confirm a 2006 LS with NAV also does this. It's not that it a loud sound, but the pitch is very bad.

I guess I should feel better that I'm not alone with this issue. Lincoln will have change the TSB to
include the 06's now
