#777 of 980 Re: '06 GT Constant Speaker Hissing [mels1229]
Jun 05, 2006 (7:32 am)
I have a 2006 Grand Prix GXP and have the hissing/humming sound. I have the Monsoon Speaker System also, OnStar and XM. Your dealer is an idiot! GM is aware of this problem and say that there is no remedy for this at this time. It is harmless so they won't repair it. Now, with my 2002 GTP I had the Bose System and OnStar -- no hissing. I think that the Monsoon System is not compatible with OnStar. I have spoken with CAC who is worthless, useless and downright stupid. I have written two letters to GM -- one to Mr. LaNeve and one to Mr. Dewar -- no response whatsoever. I do not fill out questionnaires anymore. I write across the top "I'll fill this out when you fix the humming/hissing sound." My dealer checks everytime I go there to see if a bulletin has come in for a fix. So far, no. I have told both the dealer and GM, after having bought five Pontiacs from the same dealer since 1992, no more GM cars. My dealer is actually great, but it is GM that I am furious with. GM says it is from the middle light. My brother who is an electrical engineer says it's from the OnStar. They are not compatible (OnStar with the Monsoon Speaker System). When I open my door and put my ear next to the speaker on either side I hear the hissing/humming for about fifteen seconds. Then it goes out, even if I'm cleaning the inside of the car with the door open, so it doesn't matter whether the door is open or shut, it'll go out. Right now, I just ignore it. I can hear it either from the light too or OnStar. I can't determine though which. It does not interfere with my radio or CD player at all. Once it goes off, it's off. Some people have said that their noise is terrible; really bad at high speeds. I don't have that. The CAC isn't even worth calling. They are not technicians -- more like telemarketers. All they do is look in the manual and call the dealer. Any idiot can do that. The CAC told me to go through the BBB. I did not. The CAC sent me a free oil change for my inconvenience. I already have 3 years of free oil changes!!

Your '91 won't have a sensor. Since you have checked the actual level, and it it good, try replacing the thermostat. It could be stuck open or shut. Probably wouldn't be a bad idea to replace it anyway, if you haven't done this in a while.

I have only had my car a few months about a month after I bought it it wont start all the time. If it does start sometimes it shakes. Sometimes it wont even start. I could try 10 times in a row and nothing. But it will start if I press the gas a little after i start it which sucks. I have downloaded new hardware into computer, changed fuel and air filter, had fuel sensor cleaned and new spark plugs. Can anyone help I LOVE my car and want it fixed before I want to trade it!!!

I also had a similar problem. Car would start, the engine would shut off & then could not get it restarted. Sometimes it would restart quickly, other time it took several minutes. Had the car back three times before the problem was solved. They replaced the ignition module & all is well. Hope this helps solve your probelm. Good luck.

Was wondering if anyone new why when I am driving the tachometer goes to zero and the TCS turns off? This will randomly happen and sometimes jolts the car when it does. Definitely something I wanna fix, and I am hoping it is not a $1000 fix
