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.

  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!!

  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.

  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

  I LOVE MY BONNEVILLE - 2003 Pontiac Bonneville
  By BEV12STER - October 2 - 2:00 am

  WE HAD A 1997 PONTIAC GRAND PRIX AND I WAS NOT SURE I WOULD REALLY LIKE A LARGER CAR LIKE THE BONNEVILLE BUT I HAVE FALLEN IN LOVE WITH IT. THIS WAS MY HUSBANDS CHOICE AND I WAS VERY CAUTIOUS AT FIRST THINKING IT WAS SO MUCH WIDER THAN THE GRAND PRIX BUT THIS IS NOT TRUE. IT IS VERY CLOSE IN WIDTH. IM REALLY GLAD WE WENT AHEAD AND PURCHASED THE 2003 BONNEVILLE SSEI. ITS A REAL EYE CATCHER BEING A BEAUTIFUL BLACK CAR WITH THE CHROME WHEELS. IM REALLY HAPPY WITH IT.

  Great car! - 2003 Pontiac Bonneville
  By crames33 - February 27 - 12:10 pm

  I bought a 2003 bonneville when it was 8 years old with 86,000 miles and it was in perfect condition! Besides routine things, I never had work done on it. It got great gas mileage on the highway and was a smooth comfortable ride. I recently totaled it when we got a snow storm but I walked away completely fine! It still drove and the engine sounded fine but a lot of body damage was done. Im looking into getting another bonnelville. Great cars! Very roomy (especially the trunk) and looks sharp too. I would definitely recommend this car for anyone especially for a family car.

  Fun, Good Looking and Great Value - 2003 Pontiac Bonneville
  By Schoenerman - October 13 - 6:03 pm

  This car is vastly under rated from what Ive read. The value therefore is very high due to the relatively low trade-in values. I purchased mine 2- years used with 17,000 miles on it for under $17K. It has never had a problem - currently at 76,000 miles. The Buick 3800 V-6 is the best engine on the American market. All you have to do is change the oil regularly and this car will go and go. I love it.

  GM came so close to getting this right - 2003 Pontiac Bonneville
  By SpiceUmUp - August 27 - 10:00 am

  The car is good-looking, very comfortable fro very long rides, has a large truck, gets good gas mileage, handles, and rides well. BUT: little parts break off, the latch on the trunk pass through broke the third time I used it, the paint on the radio buttons has worn off, the sun shade flops like a deflated balloon, the paint on the wheel covers is flaking, and the reception on the radio is AWFUL. How hard can it be to put a radio that can get decent AM reception in a car? My VW can get New York AM stations 45 miles from NYC that have long faded to static in the Pontiac. GM needs to start doing the little things well

  My 2003 Bonne - 2003 Pontiac Bonneville
  By Larry Stevens - July 19 - 5:46 am

  Overall I would rate this a good buy! It has performed better than expected. The only problem is something that just came up in the last 6 months which my dealer calls "knuckling," which is when you turn the wheel you experience a "grinding" sound. I am told that GM has no solution for this which is a great disappointment to me.

  Bonneville, good quality, fair price - 2003 Pontiac Bonneville
  By mdjinic - July 6 - 9:33 am

  Had trouble with the steering wheel initially. Strong vibrations in the wheel. This was corrected under warranty, and has been fine since. Engine has given me no problems. Highway mileage consistently 28-30mpg. Seat is kind of hard, and feels like it leans toward center of car, but not the most uncomfortable car I have been in.
