Pontiac G6 Years to AvoidThe weakest years — and the one you should buy instead
After reviewing every Pontiac G6 we've analyzed (5 years), these are the 3 weakest. Each one has either an absolute low reliability score, chronic repair issues, or unusually high ownership costs relative to other G6 years.
Proceed with caution
2005 Pontiac G6
The 2005 Pontiac G6 offers an affordable entry into the mid-size sedan market, but potential owners must be acutely aware of its prevalent electrical and power steering issues. While its powertrains are generally robust for their era, these systemic weaknesses elevate its risk level, making a thorough pre-purchase inspection absolutely critical to avoid significant headaches down the road.
Why this year scores low
Sudden loss of power steering assist is common, often due to a faulty electric power steering (EPS) motor or steering column torque sensor. This can lead to unexpectedly heavy steering, especially at low speeds, and GM issued extended warranties/recalls on some affected models.
The Body Control Module (BCM) is a frequent failure point, causing issues like erratic gauges, non-starting, intermittent lights, and power accessory failures. Window regulators are also prone to failure, often due to plastic components breaking.
Models equipped with the panoramic sunroof are notorious for clogged drain tubes. This allows water to leak into the cabin, often soaking carpets, damaging the BCM, and causing further electrical problems, as well as mold and mildew.
Proceed with caution
2006 Pontiac G6
The 2006 Pontiac G6 offers compelling styling and a comfortable ride for budget-minded buyers, but it's far from a worry-free proposition. Known issues with its steering, electrical system, and particularly the 4-speed automatic transmission mean a careful pre-purchase inspection and a dedicated repair fund are absolutely essential. This isn't a car you buy and forget; it's a value play for those prepared for potential maintenance.
Why this year scores low
The Electronic Power Steering (EPS) motor can fail, leading to loss of power assist or erratic steering. The intermediate steering shaft is also prone to clunking noises, indicating wear.
The 4-speed automatic is notorious for harsh shifts, delayed engagements, slipping, and eventual failure due to pressure control solenoid issues or internal wear. The 6-speed automatic is less problematic but also less common.
A range of electrical problems plague the G6, from faulty Body Control Modules (BCM) leading to various dashboard warnings and parasitic draws, to power window regulator failures and issues with the radio or charging system.
Proceed with caution
2009 Pontiac G6
The 2009 Pontiac G6 presents itself as a budget-friendly option in the used mid-size segment, but buyers must proceed with caution. While its V6 powertrains can offer a decent ride, it's notorious for electrical gremlins and power steering issues that demand diligent inspection and potentially costly repairs. It's a car that rewards the informed buyer ready to address its known weaknesses, making it a viable commuter but not a set-it-and-forget-it vehicle.
Why this year scores low
The Body Control Module (BCM) is prone to failure, leading to erratic behavior in power windows, door locks, radio, and dashboard lights. Wiring harnesses can also suffer from corrosion or damage, causing intermittent connectivity issues.
Loss of electric power steering assist is a significant and well-documented issue (NHTSA Recall 14V-153). While many units were recalled, some may still develop the issue or have a poorly executed repair. Steering rack leaks are also common.
The 4-speed automatic transmission (4T45-E) found in many models can suffer from hard shifts, slipping, or delayed engagement due to worn solenoids or internal clutch packs. The 6-speed automatic is generally more robust but not entirely immune to solenoid problems.
