Overview & Reviews

Second-generation airbags are standard, the SE comes with a standard deck lid spoiler, and the SSE gets more standard equipment. New colors freshen the aging Bonneville.

• Big car for a small price. Strong V6 engine. Stylish sheetmetal.

• Soggy suspension. Odd Halloween pumpkin taillamp illumination.

  Reliability is not worth the price! - 1998 Pontiac Bonneville
  By ATS - October 28 - 2:00 am

  We like the vehicle and the first 40,000 miles were fine. Then the problems began to appear. They included failed intake manifold (requiring engine rebuild) at 60K, ABS pump at 70K, transmission at 52K, radio twice, computer modules three times, and now at 105K, the manifold went again to the tune of $1200! For what we paid for the car, I would not recommend this model especially when GM has issued tech bulletins on these issues yet will not cover the repair costs.

  Im not alone - 1998 Pontiac Bonneville
  By Charlie B - October 16 - 10:00 am

  I bought this vehicle because it looked good, had great acceleration, a smooth ride, and comfortable seats. I liked the layout of the interior and the the sound quality of the stereo. Since owning it, I have also had to replace the intake manifold. It caused about $800 worth of damage. And I have a main seal oil leak, too. Aside from this, I still like the car a lot and will consider a newer Bonneville when the time comes to replace this one.

  Great car! - 1998 Pontiac Bonneville
  By Daniel - October 13 - 3:46 am

  bought the car from my boss with 180 thousand mls car ran great for him w/no problems and all Ive done is put in a new waterpump and synthetic oil I get 30mpg hwy and I can fly by mustangs and bmws with no ease. The car handles well at any speed and the traction control is quite admirable for the vehicle. Heads up display is great but it takes getting used to driving other cars that dont have it. I couldnt be happier with this car. I hate debating over getting something new even with the "high" mileage. The engine certainly doesnt know it has that kind of mileage on it.

  Very few, very minimal issues. Drives better 3 years later than it did when I bought it. 2 thumbs up.

  Warning! - 1998 Pontiac Bonneville
  By VincentModrak - March 4 - 9:26 pm

  I bought this car a year ago off my Dad and ever since it has been a nightmare. Shutting off randomly at first. Then the water pump blew out in October, $300. One month later my Upper Intake Manifold cracked for a second time in 3 years flooding the engine with coolant causing my starter to blow as well when trying to restart. The Upper Intake Manifolds on these cars are made of cheap plastic. They will crack on your car around 100k to 130k. Its a 1200 dollar repair bill as well. After happily owning a 95 Grand Prix, 94 Trans Am and an 02 Grand Am I was very disappointed by the Bonneville..

  Run away from Bonneville & GM - 1998 Pontiac Bonneville
  By Nomorbonnevilles - March 4 - 10:00 am

  I purchase my Bonneville SSE new in 1998. At $56,000 the plastic intake manifold cracked, allowing fluid into the cylinders which locked down the engine. Now at 102,000 miles the same thing. No help from GM either time. I am out over $2000 for this poor engineering design. The more I look into it, this is a very common problem with this engine. From day one, the car has had a vibration. I replaced the Goodyear tires with Michelin and the dealer replaced 2 more sets until he found tires that were close enough to perfect to reduce the vibration. Is the suspension so bad I have to search the country for 4 perfect tires so the vehicle doesnt vibrate?

  Great Car - 1998 Pontiac Bonneville
  By Cassie - January 26 - 10:00 am

  I bought my Bonneville with 140,000 miles on it. It now has 158,000. The person I bought it from replaced the transmission and struts. Its a really great car. I had to replace the water pump (really cheap part, and fairly easy to repair). I love driving it. Its been extremely reliable, and its nice and roomy.

  The car you dont want to buy - 1998 Pontiac Bonneville
  By james101 - January 14 - 10:00 am

  I bought my Pontiac in 1998 its been the worst car I ever owned. I like the way the engine runs and the way the car looks, but thats where it stops! I had to replace the engine in it, had to replace the main oil seal, the power stearing pump twice, and i had to change the starter twice you do not want to buy this car just for this reason! Luckly its all under warnty or i would have around 5,000 to 10,000 in work done to it.

  BEST CAR I HAVE EVER OWNED!!! - 1998 Pontiac Bonneville
  By Feyee - January 10 - 12:33 am

  This is a fantastic car, drives like a dream, corners well, handles well in ALL weather conditions. Have driven 14+ hours a day, could never do that in most vehicles. Seats are unbelievable comfortable for driver & passengers. Have enjoyed having a sunroof. VERY Reliable, if could would buy the same car over again!!!LOVE IT!!! With over 121,000 miles on it trying to decide to sell or not?? Hate to let it go.
