#75 of 118 Finally I get the hiss.........
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!

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
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?

I have a 2000 gran prix gt with 78,000 miles on it.
I have had a few sensors go bad and have replaced them no problem.
Over the last few months my car has been making these thumping or clunking noise in the front. I happens when put it into gear an move forwards, backwards, and turning the steering wheel while doing both of these. It also sometimes happens when I am braking. Haven't taken anywhere yet since I don't what is wrong with it. There is nothing wrong with the car that I know of except for the noise.
If anyone has any ideas what it is, it would be a lot of help.

My 2001 Grand Prix SE has been doing the same thing. It doesn't make the noise when changing gears, it makes the clunk when I am backing up/turning right or left and moving forward/turning right or left. I have had the bearings replaced, the struts/shocks (new tires -needed those anyway, alignment. I have had the car in a tire shop (mistake) as well as a personal mechanic and they cannot determine what it is. If you find out what may be causing this, please let me know. Thanks.
#81 of 118 Tin can sound in the front of 2001 Grand Prix when accelerating
Jan 28, 2007 (1:32 am)
I've had this noise in the front (more to the front right) of my car for some time. It only makes the noise (sounds like a loud tin can noise or something that is loose) when I am accelerating. It stops when I take my foot off of the accelerator. I've had dealerships, personal mechanics look for the noise - they cannot duplicate it (of course) and cannot see anything loose or anything that may be making the noise. Would anyone have any ideas?

Hey guys...got a quick question...
I have an 05 GP. Everything is great except for one thing.
At 1000 RPM I can hear a vibration from what appears to be right in front of the glovebox. Does anybody know what this could be?
It only happens when holding steady at 1000 RPM?
Thanks in advance!

Ok not sure if anyone else has had this problem. When I reach the speed of about 70 mph on up I can hear a howling sound now I am not sure which direction this is coming from, but I have narrowed it down from the front window cowl to the back rear, maybe a tire or something. My window cowl is actually loose. Now I was told this is the way all GP are made. So far in the mean time it is driving me nuts. I thought it might be comeing from the cowl maybe the wind is hitting it at a angle so that the faster I go the louder the noise gets. Has anyone come across this?
