Interior materials are very cheap with a lot of plastic, the base engine is slow and depreciation is faster than average.

Is the 2007 Pontiac G6 a Good Used Car?

  • No, 2007 is a bad year. Owners complain in reviews about the car’s handling, lights, and fuel system problems.
  • Reliability ratings are poor. There were some mechanical improvements for 2009, but the car was discontinued after the 2010 model year when Pontiac shut down.
  • Performance is okay from the 4-cylinder but the largest V6 is much sportier.
  • The G6 is a safe car, earning a perfect 5-star rating in government crash tests.
  • Fuel economy is good at up to 24 MPG combined.

What Do Critics Say About the G6?

  • Consumer Reports says the G6 is a mediocre and sloppy car with low ownership satisfaction ratings.
  • Edmunds gives the G6 a 4.3/5 liking the hard top convertible, but disliking the bad steering feel.
  • Kelley Blue Book users rate the G6 4.1/5 and enjoy the exterior styling but dislike all of the breakdowns.

What Common Problems Does the 2007 Pontiac G6 Have?

Problems with the 2007 G6 are fairly serious including steering issues, headlight failures, and frequent oil leaks.

Steering problems are the most common complaint from owners showing up at around 50,000 miles. The steering makes clunking and snapping noises and the steering shaft is the source of the problem. A replacement costs around $1,000.

Frequent headlight burn-outs are a widespread issue happening at around every 15,000 miles. Replacing the bulbs costs about $100, and some owners install a new headlight housing for roughly $300.

Oil leaks are another common issue on models with about 80,000 miles. The oil pan gasket wears out as the vehicle ages, costing around $400 to replace.

There are 5 fairly serious recalls including a steering u-joint, power steering motor failures, and transmission cables, which all increase the risk of an accident.

How Long Will the 2007 Pontiac G6 Last?

A properly maintained 2007 G6 should last around 150,000 miles, about half as long as top competitors like the Honda Accord. Regular annual maintenance costs are higher than rivals, at $403 per year, according to Repair Pal.

Most 2007 G6 models will have over 100,000 miles, so buyers should be prepared to replace A/C compressors for $1000, stabilizer bars costing $200, and check valves which cost $325.

How Much Is the 2007 Pontiac G6 Worth?

Blue book values range from $3,505 – 5,406, which makes the G6 about $1,500 cheaper than a Nissan Altima or Mazda6. When new, the price range was $17,245 to $28,750. Depreciation is worse than average, losing about 15% of its current value per year.

How Does the G6 Compare to the Competition?

The Ford Fusion is a popular American rival costing about $1,700 more. Reliability ratings are better on the Fusion, but the G6 is much more exciting to drive. We recommend the Fusion since they last longer and are more affordable to own.

The Subaru Legacy is another competitor that costs about $1,300 more. Passenger room and the all-wheel-drive system are better on the Legacy, but the G6 has a tighter steering feel. We recommend the Legacy since it’s more practical and reliable.
