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

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!

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?

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

have a 1999 Grand Prix. The heater fan control works on the highest setting only. When I turn the control on, the fan squeals quite a bit with a high squealing sound. Any ideas?

Replying to: greganddonna (Nov 20, 2005 8:44 pm) I would take the VIN to any GM dealer's service department and nicely ask them if they'd run a GMVIS report on it. That will tell everything from the build information, delivering dealer, any warranty work/service that was done at GM dealerships. My wife had an '01 GTP. Had it for 3 years, and, other than the cheapness of the interior materials, I had no complaints with the vehicle. It did have the blower motor resistor board issue (see my post above), and had a problem with the A/C cutting out. The A/C compressor clutch failed just out of warranty, literally the night we left the Pontiac dealership having purchased my GTO. Considering I had been complaining about the intermittent A/C for 2 years (documented), the car was just out of warranty, and I'd just purchased another Pontiac, the dealership gave me NO FLACK about goodwill-repairing the car. I know folks with Grand Prix's with 145+k miles on them, with few issues. As long as you do regular maintenance when it's required (oil changes, plugs/wires, tire rotations, belts, fuel filters/PCV valve change, coolant flush, tranny service, brake pads and rotors, and the occasional battery/alternator/water pump), there's no reason these cars can't do 125-150k+ without significant problems. --Robert |
