Vehicle: 2006 Pontiac G6 4dr Sedan w/1SV (2.4L 4cyl 4A)

I have owned this car for 3 years after purchasing brand new in 2006 and it currently has 78500 miles. Since then I have replaced the tires once, had to have the fuel injection system replaced, exhaust replaced, steering column replaced and replaced the brakes and rotors once. The engine is noisy and the car squeaks and rattles under normal driving conditions. The average MPG registers about 25 on the information center with a mix of city and highway driving. The best mileage has been close to 30. The brakes are noisy but work fine. The resale value is not great, I would not recommend buying a new G6 but a used one may provide cheap transportation.

Vehicle: 2006 Pontiac G6 4dr Sedan w/1SV (2.4L 4cyl 4A)

Have had the car 2 years. It has 27,000 mostly highway miles. When the weather gets cold, the suspension sounds like its coming apart. Had the car to the dealership 6 times for front suspension. Have changed intermediate shaft 2x, steering column 2x, struts once, and strut bearing caps once. Can't say they are not trying to fix it, but I am beginining to belive that Pontiac has a design defect in its front suspension. Have heard too many other horror stories about the same problem. I can now understand why GM is in trouble!

So far so great.

After driving a 98 malibu for a brief minute....literally, I gave GM one more chance especially for the affordability. The G6 is a great comeback! Once you get past the initial annoying defects (rack n pinion, paper brakes, and front wheel bearing) you have a car that floats at 80mph yet feels sturdy and reliable. I pray it stays this way!

What's New for 2006

The Pontiac G6 sees a host of changes for the 2006 model year. Starting things off are two new body styles: a two-door coupe and a hardtop convertible. The coupe will be available at the beginning of the model year, while the convertible hits dealer showrooms early in the 2006 calendar year. There are also new trim levels. A four-cylinder base sedan caters to those shoppers on a tighter budget, while a GTP trim increases the G6's performance threshold via the addition of a new 240-hp V6, stability control and an available six-speed manual transmission.


The G6 midsize sedan joined the Pontiac car lineup in 2005 as a replacement for the aging Grand Am. It's a big improvement over the rental-car fleet-friendly "Bland Am" and, for 2006, Pontiac has made it even better by adding coupe and convertible body styles and performance-oriented GTP trim. The G6 is the third production car to utilize General Motors' Epsilon platform, but most new car buyers will never see the family resemblance.

If it seems like the G6 looks a little bigger than its stablemate, the Malibu, that's because the Pontiac car benefits from the lengthened version of the Epsilon platform used for the Malibu Maxx wagon. This long-wheelbase platform provides two main benefits -- more rear-seat room and better handling. The extra length makes for a truly big-car backseat, and passengers will enjoy plenty of legroom. The long wheelbase also helps the Pontiac G6 deliver a smooth and stable ride.

All body styles are suited for family duty, and the convertible is notable because of its retractable hardtop that can open or close in under 30 seconds with the touch of a button. As with most Pontiac cars, the G6 is heavy on style, but this time the styling is bold yet clean with none of the plastic cladding of Pontiac cars past. The standard 3.5-liter V6 offers just enough muscle to back up the sporty looks, while the new GTP's 3.9-liter V6 goes a long way toward reenergizing Pontiac's performance-oriented image. Overall, the 2006 Pontiac G6 features a solid combination of bold styling, a cavernous interior and unique features, all at a competitive price.

Body Styles, Trim Levels, and Options

The four-door Pontiac G6 comes in three trim levels: base, GT and GTP, while the coupe and convertible come in either GT or GTP trim. Generous standard equipment on the base model includes air conditioning; power windows, locks and mirrors; a 60/40-split-folding rear seat; a CD player; and a tilt/telescoping steering wheel. The GT adds power-adjustable pedals, an eight-speaker Monsoon sound system, a rear spoiler and alloy wheels. The GTP adds sport suspension, stability control, 18-inch wheels and automatic climate control. Notable options include a remote start system, satellite radio and chrome alloy wheels.

Powertrains and Performance

Standard power for the G6 sedan comes from a 2.4-liter four-cylinder with 167 horsepower. A 3.5-liter V6 with 201 hp is also available, and all GT cars have this V6 as standard equipment. A four-speed automatic transmission driving the front wheels is standard with either of these engines. The GTP model comes with a 240-hp, 3.9-liter V6 that can be paired with the standard four-speed auto or an optional six-speed manual transmission.


The Pontiac G6 features standard four-wheel disc brakes. Antilock brakes and traction control are standard on all but the base sedan. Head-protecting side curtain airbags are optional on sedans only. The GTP features a standard stability control system. In NHTSA crash testing, the G6 sedan earned five stars (the best rating possible) for its protection of the driver in frontal impacts. Front-passenger protection has a four-star rating, while side-impact protection for both front and rear passengers is five stars. In IIHS tests, the G6 sedan received a top score of "Good" for its protection in front-offset impacts. Side-impact tests (on a G6 with the side-curtain airbags) resulted in "Acceptable" rating, the IIHS' second-highest.

Interior Design and Special Features

The interior of the Pontiac G6 features stylish seating with generous side bolsters to hold you in place during aggressive cornering. The gauges showcase Pontiac's signature font, and are set in an attractive cluster with chrome rings. Plenty of chrome and metal-look accents brighten up the interior. Materials quality is a step below class standards, with cheap plastics on the dash and console. A unique option on the G6 sedan is a panoramic sunroof that opens in four sections and remains exposed when it's open so that it looks like a roof spoiler. Rear-seat room is generous no matter which body style you choose.

Driving Impressions

In terms of power, the four-cylinder 2006 Pontiac G6 compares favorably with competitors' base engines but is lacking in refinement. The fuel-efficient 3.5-liter V6 offers plenty of torque down low for easy passing and merging, but can also get a bit thrashy at high revs. The new 3.9-liter GTP is clearly the enthusiast's choice, especially with the manual tranny. Although the electric steering is too numb for our taste, the suspension returns a surprisingly sporty ride, and the solid structure helps make the interior a serene place to spend time.
