It doesn't have anything to do with the keyless entry system. And, I only hear it when I put my ear to the door speakers on either the driver's side or passenger's side and when I sit in the car before starting it I hear it either coming from the middle light or OnStar (I can't tell which); then it goes out. It's either coming from the light or OnStar which has a microphone and since your car is always being monitored by OnStar, the microphone is obviously still on even though you turned the car off. OnStar goes off after 48 hours if your car is not in use so that the battery is not drained. Your car is always being monitored. If it is, indeed, coming from the microphone in OnStar, the only solution would probably be to put a foil box around the microphone. Who's going to do that.
 
You're not at all upsetting me with your comments. That's what this forum is all about. Speak your mind!! I appreciate all the help I get and want to know of anyone's difficulties to see if I might be or could be experiencing the same problems. So far, this car has been wonderful except for the humming/hissing. I'll say no more. Actually, I didn't even know I had this problem, until someone raised it on this forum. I sent a comment back and said I don't have the humming/hissing in my car. I got a response back saying "Yes, you do. Listen to your side door speakers and mirror." I did, and he was right. So, see, I didn't even realize I had the problem. This forum told me I did. So you shouldn't criticize me for all my complaining. This forum brought it all on!! That's why the service manager told me to stay off this site!! Have a good weekend. Have to get some work done. Hopefully, I'll be able to cut out early. Thanks for your comments. I appreciate everyone's comments and help. I'm not sensitive and don't take offense. Chats1

I didnt realize mine made the hissing sound until i read it on here too I decided to listen for it one day, and when i couldnt detect it, thats when i put my ear to the door speaker. What i tried though, with the door open, was to take the keyless entry FOB and press the door lock/unlock button, which makes the familiar "ding ding ding" sound come out of the speakers. While still holding my ear by the speaker, i sat and waited about 20 seconds, and the hissing finally stopped! To me, it just makes sense that the "ding ding ding" sound turns into a hiss after it gets "played". Try recording anything at a low volume level and play it back loud enough so you can hear it clearly. You will definitely hear speaker hiss/hum once the main recording is over.
 
As for Onstar monitoring your car, i just dont believe that. Especially if you dont purchase their monthly plan. How could they afford to constantly monitor EVERY vehicle produced with onstar at any given time, even if people arent paying for it? True, if you turn the system on to call their service center, they can track you. And yes, if the car gets stolen, they can trace the locator in your system, but i highly doubt they would be monitoring that signal every second of the day for millions of cars that have Onstar installed in them. Besides, if it IS Onstar that is causing the problem, what does having the door be open or shut have to do with them? Onstar operates whether the door is open or shut. Doesnt the hissing sound stop once the doors are shut? (or the keyless entry dinging sound stops? hint hint, lol)

#71 of 118 Friggin' Rattle ... by gxp4me

Hey everyone ... I have a problem and was wondering if anyone has some input for me.
 
Just recently I noticed that there seems to be a rattle coming from inside the drivers side door. It just started recently and isn't very loud but it is annoying since your ear is like right there.
 
Anyone have any ideas?
 
THANX

No, I haven't heard any rattling in my door. But, I believe I did with one of my GTP's. The dealer fixed it. What dealer did you buy your car from, since you're from South Jersey? Take it back to them. You're under warranty. I bother my dealer all the time if I have a problem. They're used to me and are a great dealer.
 
Now, I had a inch and a half long and half inch wide piece of sheet metal in my rear tire. When I got home the other night I heard this loud hissing. Computer came on halfway to the gas station telling me to check pressure. I already knew. I went straight to the Amoco station and they didn't think it could be plugged. They plugged it and it held. They told me to come back the next night for them to check the air. No air leakage at all so the plug is holding. They suggested buying four new rims and four new tires to have on hand!!! I said no, but was thinking, what are you nuts?? That could be an easy $4,000. I did call Bridgestone though and they didn't have the right size of our tires in their computer. They had for the rears REO50, not REO50A. The guy said they would have to track the tire down and it would take 2-5 days. He also said it must be awful in the snow; I said the car performed this past winter superbly in the snow. He was surprised. I said I do not want winter tires. He said I would never put winter tires on that car anyway. I just am writing this for everyone's info, if you're interested. Chats1

keep in mind you need to reference the TPC code on the tire when replacing the stock Bridgestones, not just that it's a 050A

Thanks for your reply. Yes, I do know about that TPC number and I mentioned that to him also. I know it is important because that shows that it's a genuine GXP tire. I would completely check all the numbers anyway before I had any tire mounted. I think I'll stick to the dealer though. They said only one day to get the tire; Bridgestone said 2-5 days. Ugh!!! My tire's fine though; the plug worked; no leakage. Thanks.

#75 of 118 Finally I get the hiss......... by ocmike3

Jun 18, 2006 (6:04 pm)

I now know the hiss/hum that some of you have been complaining about... I went to get something out of the GXP the other night. It was dead silent in the garage and I open the door and as I was looking around inside for what I needed, I heard a faint "sssssssssssssssssssssssssssss" sort of like a radio that is in between channels, but very faint. It lasted for maybe a minute or so and then stopped. I must admit, that some of you either have excellent hearing or yours is definitely louder than mine. It is definitely something to do with the radio or OnStar. Since my radio/stereo was turned off, I suspect it was OnStar. It doesn't bother me any, but for conspiracy theorists - Big Brother is using OnStar to keep track of us!

#76 of 118 Headliner rattle by erichthecatt

Ive got a rattle in the headliner around my sunroof on the gxp. It seems to be worse when its in the tilt position, or when the cover is open. Does anyone have or had this problem? If so, what was the cure?

#77 of 118 Whining noise by pckeenan

Oct 18, 2006 (11:07 am)

I have a 2000 Grand Prix GT and have noticed a high pitched whining noise that increases at low speed accelerations. I've also noticed that when accelerating at low speeds, the engine drags/shutters.
 
Not sure if these two are related or separate problems.

If the rattle is by the actual moving roof section, it might be one of the tracks are slightly loose. If it is a new car it should still be under warranty right, so just take it back to the dealer and ask them when you get some time.
 
pckeenan, is it a whining noise or a hissing noise?
