1998 Pontiac Grand Prix GTP from North America - Comments

What a piece junk... keep in mind I have only had it for a month!

Had to rebuild any form of suspension (bushings, tie rods, etc. too) and it still rides really bad.

Tranny rebuild has only 25K and seems to be close to death already.

Stereo and speakers called it quits which cost me $900 for just decent aftermarket stuff (8 speakers and head unit)

I bought this car because I do a ton of long distance highway driving, and figured it would be great for it considering the original owner sold it to me with full service records and it was in excellent condition especially for the miles. It seemed like the perfect long haul kinda car. WRONG. The gas mileage sucks (avg 16 MPG!), the car is super uncomfortable, and its power is useless because its front wheel drive. I went from loving this car to hating it within a week of owning it. The only thing its got going for it is its looks. Oh yeah, the headlights are dangerously dim too. I wanted to own an American vehicle for a change, but come on GM, get your sh*t together!

This reviewer did not buy a new car, he bought an 8 year old used car with 138K miles on it.

And all of his complaints are for things he should have either detected on a pre-purchase inspection or at least anticipated on a car with that much mileage.

It is laughable that someone would buy a front-wheel drive car and then complain about it being front-wheel drive!

I agree. I have a 1998 gtp and wow very nice? 115000 on it now still runs like the wind.

I also have a 1998 Grand Prix GTP. I love my car. It has about 91000 miles on it and have had no problems what so ever. And with my car I usually get an average of about 20mpg. This is only because I can't keep my foot off the gas pedal. This car is like a rocket on wheels. All my friends with Mustang GT's are jealous because I have two cylinders less than them and I am front wheel drive and I can really give them a run for their money.

I own a 1998 SE with 162,000 miles and it still runs like the day I bought it with 59,000 miles. I service it myself regularly, and very seldom do I have to make major repairs... none of which have cost more than $200. Only major problem is the windshield leaks, it may be from the firewall. I know it is not the condenser because it only happens in the rain. I've resealed the windshield with silicone and it still leaks. Other than this, I'd buy another one any day!!! GREAT car for the American dollar.

Just wanted to let anyone who is curious know that the leak that is brought up so often is GP's is from around the fresh air intake for the air conditioner. That problem should be a free fix because it is from faulty seal installation. It is not. I really enjoy my GP and with 96K I have to replace the ball joint and tie rod. $80 in parts, 1200 in labor. No the dealer is not where I took it, you GM haters.

1998 pontiac grand prix water leak.

The problem your having is the winshield has been replace and they left out a rain deflector under the black cover under the wiper arms a little RTV and some weather stripping will stop the water from entering the air box and dripping on the floor

the glass repair man told me about it is easy to leave out if you don’t know what the part is for it might even still be there pushed down out of the way.

I own a 98 Gp/SE with 143K on the clock that I drive every day (approx 325 miles per week). Other than routine maintenance, tires (Bridgestone HP 50s - great all around tire), aftermarket rims, front struts and a K&N filter, I can honestly say I'm very pleased. I've used Mobile-1 since 34K and change the tranny fluid & filter every 18 months. Maybe a bit excessive, but I do rely on her heavily. I'm getting ready to do struts, mounts, and springs (Eibach's) on all four corners, and I know it'll be costly, but I'm not in the mood for car payments. And suspension refresh is to be expected at 143K. Anyway, I've owned cars and motor cycles from Japan, England and the US and one thing is universal - you've got to take care of them. Routine mx is critical if you expect trouble free motoring. Be safe and enjoy the rest of summer (I'm from PA).

Did you replace the struts? $900 for a "decent" audio system... I don't believe it.

I have a GTP with 152,000 miles and I get 33mpg on the highway at 70mph. In the city I have never gotten below 19mpg and I drive it pretty hard.

The leak is either coming from a strip of rubber molding underneath the cowl at the bottom of the windshield, or it could also be a missing rubber grommet that drains the condensation from the A/C. I had the missing rubber grommet and every month or so it would dump a large amount of water on my passenger floor. The rubber grommet cost about $5 and just slides over a tube protruding from the engine side of the firewall (it's easiest to get through if the car is in the air).
