Review of the 2005 Pontiac Bonneville

  • 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. However, the rear-drive Chrysler 300 offers a better package overall.

  • Safety
  • Pros

    Loads of gee-whiz features, solid handling, powerful V8 in GXP, excellent crash test scores, large trunk.

  • Cons

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

  • What's New for 2005

    The OnStar communications system is now standard on all Bonnevilles.

Love it - style, performance,

Vehicle: 2005 Pontiac Bonneville SE 4dr Sedan (3.8L 6cyl 4A)

This car is great. I bought with 90K. It now has 102K. I love the style. Very stylish car. Its big!! Its comfy. It has a very quiet cabin. The gm 3.8 is an amazing engine. Actually got 30 mpg when doing a highway trip of 480 miles. with 16 gallons of gas. It has a big gas tank at 18 gallons. Don't need to fill up much. Normal MPG is about 25 with highway/city mix and not winter out. One problem it died on me on the freeway. Kinda scary. It was the Mass airflow sensor. It happened out of nowhere. No engine lights. I would replace this at 100k miles or sooner. That's when it died on me. Besides for that no problems. You can probably have autozone replace for you.

Amazing underrated car

Vehicle: 2005 Pontiac Bonneville SE 4dr Sedan (3.8L 6cyl 4A)

So far owned for 3,000 miles. I got this beautiful car for a bargain price with 90k miles. It drives like it has 30k miles. I've gotten between 23 and 27 mpg per tank so far. Nothing has broken except for a burned out head- light bulb. Very smooth torquey engine with silky smooth shifting transmission. Lots of style. More style than all the imports for sure. I love the look from the back and side especially. Only cool Chryslers and Dodge's have more style but they are troublesome. This car feels heavy and well-built and safe. Nice looking interior with a large trunk and back seat. This car is big and a bit tricky to maneuver in parking lots and city but its a dream on the freeway.

Awesome vehicle, bring it back!

Vehicle: 2005 Pontiac Bonneville SE 4dr Sedan (3.8L 6cyl 4A)

Well, about one month after we purchased the car, it had a recall on a steering linkage. Since then (it now has over 100,000 miles on it) it is going strong. Good mileage (20 in town 29 on the road). Bullet proof 3800 Series II engine. Only the normal wear and replace things such as tires and brakes. We just did the first tune up and are getting ready to replace shocks, struts, coolant flush and refill, new surpentine belt and transmission service, hope for another 100,000 out of it! One of the best cars we've ever owned for durability and comfort.




Nice deal

Vehicle: 2005 Pontiac Bonneville SE 4dr Sedan (3.8L 6cyl 4A)

This is a large, safe, 4 door sedan built by the UAW in Michigan. It is based on GM's G platform which also underpins the Buick Lucerne and Cadillac DTS, and it is lighter than both of these cars. Most of the shortcomings of the Bonneville have been addressed in GM's newer models, but if you can live with them, the price is incredible.




Never again

Vehicle: 2005 Pontiac Bonneville SE 4dr Sedan (3.8L 6cyl 4A)

Not a good car through rain and puddles. It only has 27,000 on the odometer and the trans is shifting hard, clanking noise every now and again in front. Brakes have been fixed once and checked three times. They still squeal. Mechanic says it's the brakes they put on cars these days. Also has blind spots. Paid $22,000 and is simply not worth the money. I'm trading it in A.S.A.P




Troubles
