Review of the 2003 Pontiac Bonneville

  • Pontiac bills the Bonneville as "Luxury with Attitude." That's an accurate description, given its basis on Cadillac's Seville platform and available 240-horse supercharged V6 engine. If traditional Pontiac styling twists your crank, and you want a large sedan packed with performance and features, the Bonneville is your kind of ride.

  • Safety
  • Pros

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

  • Cons

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

  • What's New for 2003

    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.

Vehicle: 2003 Pontiac Bonneville SE 4dr Sedan (3.8L 6cyl 4A)

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. I'm 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.

2003 bonneville with 160,000 miles

by on
Vehicle: 2003 Pontiac Bonneville SE 4dr Sedan (3.8L 6cyl 4A)

I am 18 years old and this was my first car. I bought the car two years ago with 130,000 and it ran great. I still have the car and it's still going strong with 168,000 miles. The only thing i have had to do with it is scheduled maintenance (oil changes, balancing tires, etc). Fuel economy is great for a 6 cylinder. It has a very smooth ride, and i like the comfortable leather seats. It also rides quite well at 120 mph. One of the only things i do not like about this car is that it is quite heavy, and does not stop as quickly as many other cars I have driven.




Hate my bonneville

by on
Vehicle: 2003 Pontiac Bonneville SE 4dr Sedan (3.8L 6cyl 4A)

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.

My 2003 bonne

by on
Vehicle: 2003 Pontiac Bonneville SSEi 4dr Sedan (3.8L 6cyl S/C 4A)

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.
