#4269 of 4431 Grand prix 2001 road noise? by thunder_320 Nov 01, 2005 (6:24 am)
I have a 2001 GT w/100,000 miles, when idling there is no noise, all is as it should be. Recently I've noticed a noise, similar to a low roar while driving. It remains constant and raises in pitch and level as I speed up and lowers when I slow down. It doesn't get high or shrill , but it is very noticable.   The sound is coming from the front end, my tires are new and balanced. The care doesn't shimmy or shake and engine response is normal. I do not detect any unusual odors either, such as exhaust or anything cause by friction. Also I see no visible problems upon inspection of the engine. Other than the noise my car runs and performs fine, but I am very concerned. Thanks Replies to this message: bmwguy2 (Nov 13, 2005 5:33 am)

Almost 200000 miles... tachometer quits working, TCS light comes on and want go off, HUD display races up and down, Lighting on the Trip Computer/Driver Info display flashes off and on, ABS light comes on and off, Alternator surges higher voltage, Auto door locks latch/unlatch while turning steering wheel, PRND321 dash lights flicker off & on, Analog speedometer dances. However, there are no problem codes being logged by the ECM. Would appreciate all responses with suggestions for diagnostics!

Replying to: thunder_320 (Nov 01, 2005 6:24 am) hi there ,i have a stock 2001 grandprix special edition coupe,i also work for a bmw dealer here in new jersey ,well to the point,it seems most likely its a wheel bearing noise,if possible when your driving ,on a safe road ,with no other cars ,shut the engine off and put into neutal,and see if you can isolate the noise ,if you slightly turn steering wheel to the left or right ,the noise may change if its from the front ,or you can have the vehicle liftef off all four tires and spin tires,listen for roughness when they are spinning,by hand usually a bad bearing will not be quiet ,due to the mileage its a good chance ,i know bmws but noises dont change from vehicle to vehicle,also check for ,after driving and braking if one brake caliper is hotter than another ,it could be hanging up alittle ,again would cause noise,but you might smell brakes getting hot on this one,please let me know ,also if you can get to a lift ,have someone get in car ,raise up and put vehicle in drive ,on lift and have some-one search for noise underneath car ,was car ever in a flood or in alot of water ,water may have gotten past the seal and damaged the wheel bearing ,if its a bearing ,hope this hepls ,michael

Replying to: mrsb (May 11, 2005 6:06 pm) hi there .it seems that the coolant level sensor is bad ,when coolant is cold,it contracts ,as it warms up,it expands ,it seems that the level sensor is bad ,if you have a gm extended warranty,this might be covered ,its on the right side of the engine looking front to rear,but you have to gain access from under car to remove hose and clamps from engine to replace,it does sit high in engine compartment,where you might be able to get access,but i doubt it,i have a 01 gtp special edition,michael
#4273 of 4431 95' GRAND PRIX GTP PROBLEMS by hayze Nov 16, 2005 (8:10 am)
I PURCHASED MY 95' GRAND PRIX GTP 3 YEARS AGO. A YEAR AFTER I BOUGHT IT THE TRANNY WENT OUT OTHERWISE IT'S RUN GREAT. I REALLY LOVE MY CAR. ABOUT A MONTH AGO IT STARTED TO IDLE ROUGH WHEN FIRST STARTED AND WOULD SOMETIMES SHUT OFF. IF I START DRIVING RIGHT AWAY AFTER A FEW BLOCKS IT'S FINE. BUT IF IT SITS FOR A FEW HOURS IT HAPPENS AGAIN. I'VE CHANGED THE FUEL FILTER AND THE SPARK PLUGS. I'VE PUT FUEL INJECTOR CLEANER IN IT AND NOTHING SEEMS TO BE WORKING. I HAD IT HOOKED UP TO A COMPUTER AT A LOCAL SHOP AND THEY SAID NOTHING SHOWED UP. WITH IT GETTING COLDER OUT THE PROBLEM SEEMS TO BE GETTING WORSE. ANY IDEAS WHAT COULD BE THE PROBLEM?

#4275 of 4431 Help Please by greganddonna Nov 20, 2005 (8:44 pm)
Hi We are new to this forum and we love it and find it very informative! We have a chance to buy a 1 owner 2001 Pontiac Grand Prix very clean with 70K miles and new tires for $6500. But after reading all of these posts there seems to be a pattern with certian problems. My question is is this a good buy? Would you buy the Grand Prix if you had it to do over? Also tried to get info about the car with the vin from CARFAX and the like and no info is availalbe, is that normal if the car is clean????   Thanks so much!!! Any info will be greatly appreciated!!!    Greg and Donna Replies to this message: hammen2 (Nov 25, 2005 12:23 pm) kairos (Apr 20, 2006 5:42 am)
