What To Look For Before Buying

Before purchasing a Pontiac G6 car, it is crucial to conduct a comprehensive inspection, similar to any other vehicle. To assist you in making a well-informed choice, we have identified three key factors that should be considered based on data sourced from Car Complaints.

First Thing To Look For

Engine: During the engine inspection of a Pontiac G6, it is crucial to check for leaks, assess the oil level, and examine the head gasket condition. If any issues are found, you have a couple of choices. Firstly, you can negotiate a lower price with the seller to account for the repairs you will need to undertake. Alternatively, if you really like the car, you can request that the dealer resolves the issues as part of the deal. However, if the seller is unwilling to agree to either option, it is advisable to consider looking for a different car. It is important to avoid acquiring a problematic vehicle that may lead to future headaches.

Second Thing To Look For

Power Steering System: In addition to the engine, it is advisable to thoroughly check the power steering system of the Pontiac G6 during the inspection. This is particularly important, considering that power steering issues are commonly reported on the G6. Make sure to assess the power steering system for any indications of leaks, abnormal noises, or difficulty in steering. If any problems are identified, they should be addressed and rectified promptly.

Third Thing To Look For

Low Beam Headlight: Based on owner reviews on RepairPal, low beam headlights are another commonly reported problem (some owners have reported this as a recurring problem). Therefore, it is important to confirm that the beam headlights are functioning properly.

Is It Worth Buying The Pontiac G6?

Deciding whether the Pontiac G6 is worth buying depends on factors like personal preferences, budget, specific needs, and the condition of the car you’re considering. Here are some points to keep in mind:

Positive aspects:

  • Affordability: The Pontiac G6 has an average used price of $8,608, making it a relatively affordable model.
  • Numerous standard features: The 2008 model, for instance, offers air-conditioning, a tilt/telescoping steering column, a four-way manual driver seat with power height adjustment, as well as a 60/40-split-folding rear seat.
  • Three body styles: The Pontiac G6 is available in sedan, coupe, and convertible body styles.

Negative aspects:

  • Reliability concerns: Mixed reviews exist regarding the G6’s reliability, with reported issues regarding power steering, low beam headlights, oil leaks, and more.
  • Average running cost: G6 owners report that the vehicle has average running costs, which may not be appealing to those seeking long-term savings on maintenance, repairs, and fuel expenses.

Considering the reliability concerns and average running costs of the Pontiac G6, it may be advisable to explore other options rather than proceeding with the purchase. However, if you are still determined to buy a Pontiac G6, a thorough inspection and test drive is recommended. It is also a good idea to consult with a trusted mechanic, who can assist in the inspection process if needed.

While the overall quality of the Pontiac G6 cars is not necessarily poor, it is worth noting that certain models should be approached with caution. Based on data from Car Complaints, the 2006 model stands out as the most problematic, followed by the 2007 and 2008 Pontiac G6.
