Pontiac Grand Prix, Sedan
Nov 20, 2005 (8:44 pm)
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!!!

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?

There is a "resistor board" which controls the fan speed on these models which goes bad. It's about a $20 part, and requires some minor dash disassembly. I'd see if I can find a non-GM mechanic to do the work - shouldn't cost you more than about $35 in labor, and this is a VERY common problem on the '97-'03 Grand Prix bodystyle. I haven't heard of the squeal - I'd do the obvious fix and see if that continues, troubleshooting it further only if it does.

The price sounds great, but hmmm... no information available from CarFax? Sounds weird.
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.

I am having the same problems. I think my alternator is going. The alternator is only giving 13.2V when running and it used to give 14.5 when I first bought it.
I am also going to try and find the computers and tighten them down. My ABS light comes on when I hit a large bump in the road.

If your ABS light continues to activate on bumps after you change your alternator and/or battery, I'd suspect a wheel speed sensor - usually part of the hub assembly.

I bought my 2001 Grand Prix GT, V6 3.8L, new and all the work has been done by the dealership that I purchased it from.
The driver's side window motor went bad, the head gasket had to be replaced (defect with manufacture) and recently I just had the belts, spark plugs & transmission fluid changed and the radiator flushed at 127,000 miles. (This car had been driven 90 highway miles per day, 5 days a week on it due to my work) The car ran fine before the routine work was complete and I wanted the tuneup done to get the car ready for winter. Before taking the car to the dealership, the fan (inside) the car would not work at the number 1 position, but would work on 2,3,4,& 5 - it now works at 5 only.
They advised me that the car would need a battery and tires of which the tires have been replaced. The battery was going to be done tomorrow. The car has always gotten it's oil changed when needed and other routine maintenance.
My problem is that since this most recent work, the car doesn't want to start, it will make you think it has but then dies out (could be related to battery) but before the dealership looked at it - it would start fine. Then driving it home this evening it started to idle so hard it felt like the car wanted to surge forward, like strong surges. It smelled like something was was burning and when my husband shut it off we heard this clunking noise from the engine compartment. Does anyone know what is going on and if I should attempt to drive it to the dealership?
Has anyone ever had this happen before? It's very strange that these things weren't happening before.
Thanks for your feedback - I greatly appreciate it.

Hmm... I would really suspect something the dealership did - improper gap on the spark plugs? Bad/incorrectly-installed wires? Clunking underhood, maybe a belt is improperly installed/is slipping?
BTW your fan problem is common... a "resistor board" under the dash is the culprit, and I doubt the dealership did anything.
If it easily starts, I'd take it in, but if it is hard-starting or high-idling, I'd call them and make them come pick it up (presuming your problems started on the way home from the dealership). Is the Check Engine light on?

Thanks for responding!
The check engine light isn't on. I drove it to the dealership this morning (only a mile away) and dropped it off. They aren't in today - but they'll have it first thing tomorrow.
This morning the car started right up but as soon as I touched the brake to shift it to drive - it would stall. Started it in neutral, then shifted and drove off. When I would have to use the brake, the idle would start acting up and it was if the car was trying to jerk forward. Stop lights weren't a fun experience.
The dealership wouldn't have done anything intentional do you think? I've used them for years and and found them to be good to work with. But I did have another dealership change the oil in my old van (or say they did) and "forget" to change the oil filter. So I guess anything is possible.
Thanks again for your response. This will help me to resolve this with the dealership. Chele5

Though the summer Potenza's on The Pontiac Gran Prix GXP are were allegedly formulated to handle snow I would like to change over to a dedicated winter tire. Can I get away with just replacing the front tires? Can I safely replace a 255/45-18 with a 235/45-18. Any input would be greatly appreciated.
