Overview & Reviews

The Bonneville gets only minor changes for 2003. Base SE models now sport newly styled 16-inch steel wheels and a standard AM/FM/CD stereo, while all models can be upgraded with optional XM Satellite Radio. Previously standard side airbags are now optional on SE and SLE models.

• Loads of gee-whiz features, solid handling and drivetrain, excellent crash test scores, large trunk.

• Average interior materials, overly complicated controls, poor resale value.

  Nice ride - 2003 Pontiac Bonneville
  By tony - October 11 - 6:46 pm

  I traded my 2004 Grand Prix for this car. It’s a much better ride than the GP. Fuel economy 23 city 28-29 highway. 1 problem since owning was a repair of $46 dollars. Other than that it runs like a top. Comfort. It rides better than my 2002 Concorde Limited.

  Great Pontiac Ride - 2003 Pontiac Bonneville
  By Mike T. - August 19 - 4:00 am

  This car is a pure joy to own. In 150,000 miles there have been no repairs other than regular maintenance and crash repairs. The fuel economy is very good, better than some of my friends with much smaller cars. Just a note, this is just another in a long line of nearly flawless GM cars that I have owned. Bravo!!

  Sweet n powerful Bonnie - 2003 Pontiac Bonneville
  By Ming - April 9 - 10:00 am

  I love these cars. Great tire squealing acceleration off the line, none of that "240 hp" that only comes 10 minutes into driving it up to 10,000 rpm. Instant power. The interior is comfortable, but the headrest is a little odd - it supports my head only when tilted forward. Love the heads up display and at your fingertips radio controls. Only problem was insulation in the trunk at one spot leaked. Fixed under warranty.

  Love my Bonneville - 2003 Pontiac Bonneville
  By Honeypml2003 - September 18 - 2:46 am

  I really love my car! I have had it for over a year and have driven it to death. The only problem is that the fuse to my interior lights keeps blowing. Other than that it is comfortable and a fun car to drive. When you keep the oil changes current it really accelerates! Gas mileage is okay! Oh and the plastic things in the car keep breaking (cover for the vanity mirrors for example) Other than that it is wonderful and a pleasure to own! IT is VERY reliable!

  Steering Nightmare - 2003 Pontiac Bonneville
  By Pete - August 13 - 8:36 pm

  A lot of fun to drive, not bad on fuel consumption, and has good looks. At 5,000 the steering rack was replaced, and at 26k we had the intermediate shaft in the steering box replaced w/ a new part. At 40k the cluck,cluck, noise started again "intermediate shaft" the dealer along w/ GM claims there is no safety problem and live with the noise. Im 55 and this was my last GM product.

  Nice Car - 2003 Pontiac Bonneville
  By shumpert - May 17 - 10:00 am

  First Pontiac owned, good power, handling is excellent for a full size car, quiet and interior styling good. back seat is a little rough for 6 footers, and not to thrilled about placement of the battery underneath the left rear passenger seat. Otherwise, a fine automobile for the price.

  bonneville ssei - 2003 Pontiac Bonneville
  By pontiac - May 17 - 10:00 am

  The front seats do not go back enough. Getting in and out is not very comfortable. The light control is not in a comfortable position. The windshield wiper control is in a bad position also. I am 52" and when larger or taller people enter the car the front seat is very uncomfortable. I also do not like the 4 dr idea. I owned a Pontiac grand prix gtp and enjoyed it very much. In fact this Sept 2003 I will be buying a new grand prix. They handle better and are a lot more fun to drive and have a lot of room in the front.

  First Impressions - 2003 Pontiac Bonneville
  By jonnyoz13 - April 11 - 7:33 pm

  Have owned this used Bonneville a little under 2 months. Some notes: Fuel Economy; around 27 average in mostly hwy driving, not bad. Comfort; very nice ride, front seats could use additional bolstering in the thigh area. Performance; very good, accelerates nicely when pushed. Accomodations; huge trunk, back seat roomy-head clearance ok even with sunroof, heat/ac with dual climate works nice (although fan runs at same speed for both sides, just temp difference. Annoyances; data computer seems off- gallons used short about 1 gallon out of 17 which shows misleading fuel economy-miles to empty-etc, oil life monitor at 67% after 3300 miles? Conclusion; great family cruiser, 9/10 stars
