Vehicle: 2006 Pontiac G6 GT 4dr Sedan (3.5L 6cyl 4A)

My mother bought this car in 2008 I believe, and gave it to me about 2 years ago for better mpg. It was perfectly fine never had a problem. Then everything started to go wrong. The passenger headlight went out, the CD player stopped ejecting the CDs, the brakes squeak no matter what, I've already tried to fix it multiple times, and my power steering just recently went out almost caused me to wreck, scared the living daylights out of me. I didn't even have all these problems with my 87' IROC.

Best car yet!

This car was the 4th car I have owned, and I was warned always to not buy this brand because of the way pontiacs usually turn out to be, But I love my car! its by far my favorite and im pretty sure I will drive this car until it just wont go anymore! I just love the way it drives and the way it handles, also its very spacious and great to take on long trips! The people who are having many problems are victims of cars that were not maintained and to be honest the way that they drive. If you drive it easy it will last you forever :)

Excellent purchase

Vehicle: 2006 Pontiac G6 4dr Sedan (3.5L 6cyl 4A)

I purchased my 2006 Pontiac G6 with less than 400 miles in March, 2006. This car has been my daily driver for the last 7 years. I have put over 197,000 miles on this vehicle. Of course, I have had regular routine work such as brakes and rotors. Have had a wheel bearing replaced. Very pleased with this car. Just wish it was bigger now that I have children.

Main problem: passenger side head

Vehicle: 2006 Pontiac G6 GT 4dr Sedan (3.5L 6cyl 4A)

I've owned my 2006 G6 sedan for two years. Drove my long commute to and from work each day reliably and comfortably. Main problem with these cars is the passenger side headlight. GM used a sub quality harness which plugs the headlight assembly into the main harness. It overheats and melts (if yours hasn't yet, it will) Best thing to do is bypass the plug wiring in your own spade connectors. Headlight ground went on it too, had to wire my own. Wish there was a recall on this. Sometimes I get a check engine light which is accompanied by hard shifts. It clears up on its own. Drivers door seal leaks water. Other than that, just brakes and normal ware items. Overall car is very reliable.

Wonderful car

Vehicle: 2006 Pontiac G6 GT 4dr Sedan (3.5L 6cyl 4A)

If I didn't know much about used cars I wouldn't like this one. I have had some issues, but nothing that wasn't expected out of a vehicle with over 100,000 miles that wasn't maintained properly. Everything still works on it, and nothing major has gone bad. The most I've had to do was replace back rotors and brake pads after I got it because they had been let go for way too long. It's a joy to drive, the perfect balance of feedback and comfort. It has a good pick up to it, and wouldn't have any issues at highway speeds if I didn't have a bent wheel (aftermarket wheels). Even for not being maintained this car is surprisingly sturdy and is still running strong.

Great car

I've had my G6 for about 3 years with about 32,00 miles on it. I have about 99,000 miles on it now. I've had a few minor issues but nothing major and nothing compared to the issues described in a lot of the reviews. I love my car, it drives great, handles great and sounds amazing!

Full 2006 Pontiac G6 Review

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.
