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 this car

by on
Vehicle: 2005 Pontiac Bonneville GXP 4dr Sedan (4.6L 8cyl 4A)

Bought this GXP in Feb 2005; actually bought it for my wife; not only does she love it , but I like to drive it; I grew up in the muscle car era and this reminds me of it. Love the Northstar V8. The car has been very reliable with decent mileage considering the power available City 14.5/Highway about 23. Love the HUD, memory driver features(seats & mirror, plus radio. Ours is Black with Grey interior; it's a real head turner. The car is garage kept and has very low mileage (driven to/from grocery store by a little old lady; we are in our late 60s). Her previous car was a 1996 T-Top Camaro RS, with 3.8L V-6, also low mileage, 10 years, 34,000. We plan on keeping the GXP a Long time!




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

by on
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.

Bonneville good but bad

by on
Vehicle: 2005 Pontiac Bonneville GXP 4dr Sedan (4.6L 8cyl 4A)

GPX is a great car, but if you buy a used one please get a 0 deductible warranty. Have had $6000.00 of work done. lucky all but about $800 was covered (Shocks and brake-not covered), all problems caught by dealer during normal maintenance. The problems,oil and H2O leaks, rear drive problem, Onstar/radio, control for heat and air condition, wheel bearings eta. I have one year left on warranty- lucky me.

Awesome vehicle, bring it back!

by on
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.




We love this car

Vehicle: 2005 Pontiac Bonneville GXP 4dr Sedan (4.6L 8cyl 4A)

We purchased this car in Feb 2005; we have had abolutely no troubles with it. It is fun to drive, reminds me somewhat of the muscle car era I grew up in with a touch of class & luxury. Ours is Black with gray/black leather interior. We get the oil changed every 4-5 months as we don't drive a lot of miles, pleasure only, three vacation trips of 1,500-1,600 miles or so included in the 14,700 now on the car. Actually it is my wife's car; her previous car was a 34,000 mile, T-Top 1996 Camaro; she didn't drive that one much either; about 6 vacation trips in that car; it had the 3000 V-6
