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.

  Brakes, Vibrations, and Steering Column - 2003 Pontiac Bonneville
  By Tom Wallace - March 14 - 5:23 am

  This car is the biggest lemon we have ever purchased. From day one, it has had an extreme vibration that no one has been able to get rid off. The car has 44,000+ miles on it. After 2 new sets of Michelin tires, countless tire balances, alignments, badly warped rotors at 43,000 miles, sticking calipers, drivers seat that shifts when taking curves, and 2 fixes to the steering column, we still have bad vibration, brake problems, and a seat that shifts - to the tune of about $3000. Oh yes, also had water coming in from under the car as well as in the trunk. I hate this car! GM will not get another sale from me.

  Hate my Bonneville - 2003 Pontiac Bonneville
  By belyache - December 16 - 4:46 am

  Purchased used, after 2 years I started noticing some transmission slippage from 1st to 2nd.. Then came the the transmission not engaging 1st. I had the transmission replaced, it worked fine for about 5 months. Now it is doing the exact same thing. It also has an annoying steering grind. I would not recommend this car. I have also heard others complaining of transmission problems with this car.

  A Beautiful Vehicle - 2003 Pontiac Bonneville
  By Gregory Tocco - December 9 - 11:56 am

  I purchased this Certified Used Vehicle from my local Chevy Dealers Used Car Lot. This 2003 Pontiac Bonneville SLE is easily one of the nicest vehicles I have ever owned (and Im 46). The overall styling is striking and I get a thrill everytime I see it! Im getting almost 24 mpg in mixed (city/hwy) driving. The reliability is exceptional! I simply love this car! I am also very disappointed that GM has discontinued producing the Bonneville (as of the 2005 model year). I will drive this car for quite a long time. In fact, my plan is to drive this car for at least another 5 years, then look for a clean 2005 Bonneville GXP and be in Bonneville Heaven! (I know the 2005 GXP is the best ever!!)

  Best Family Sedan On the Market - 2003 Pontiac Bonneville
  By Joe Dixon - January 21 - 10:00 am

  We bought our Bonneville just last month, we previously had owned a 94 Bonneville. The car itself has a good design its quite attractive, for someone who has a family and wants something big enough to easily ride in comfort and have plenty of power doing so, then this is the car. The engine sound is amazing. As soon as you open up the engine the supercharger roars, its really gives you a rush. When test driving the vehicle, a Ford Mustang GT pulled up becide and we had a bit of a drag race, we easily pulled ahead of him, beleive it or not the pedal was not to the "metal".
