The 2006 G6 is a mid-size sedan built on GM's Epsilon platform with multiple powertrain options. Notable for transmission cooling failures, steering assist issues covered by recalls, and engine bearing/piston problems especially in the 3.5L/3.9L V6 engines under stress or neglect.
Transmission Oil Cooler Line Failure Leading to Transmission Damage
Common · high severity
Typical onset: 70,000-130,000 mi
Symptoms: Pink milky fluid in coolant reservoir (coolant mixing with ATF), Transmission slipping or delayed engagement after coolant contamination, Overheating transmission, burnt smell, Complete transmission failure if coolant enters valve body
Fix: Replace transmission oil cooler and lines (2-3 hrs), flush cooling system and transmission. If contamination has occurred, transmission rebuild or replacement often required (8-12 hrs labor). This is the most expensive and common catastrophic failure on this platform.
Estimated cost: $800-1,200 for cooler/lines only; $2,500-4,500 if transmission replacement needed
Electric Power Steering Assist Failure
Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Service power steering warning on dash, Complete loss of power assist (manual steering suddenly), Intermittent assist loss especially during cold starts, Whining or grinding noise from steering column
Fix: Most often the electric power steering motor or control module fails. Steering column or rack replacement required (3-5 hrs labor). GM issued recalls (14V345, 10V388) for software updates but hardware failures still common after the fix.
Estimated cost: $600-1,400
3.5L/3.9L V6 Engine Bearing and Piston Failures
Occasional · high severity
Typical onset: 90,000-150,000 mi
Symptoms: Knocking or ticking noise from lower engine, especially on cold start, Loss of oil pressure, oil pressure warning light, Metal shavings in oil during changes, Excessive oil consumption (more than 1 qt per 1,000 mi), Catastrophic engine seizure if ignored
Fix: Main or rod bearing wear from inadequate lubrication design or extended oil change intervals. Requires engine removal, short block replacement or full rebuild (18-24 hrs labor). The 2.4L I4 is more reliable in this regard.
Estimated cost: $3,500-6,000
Fuel Pump and Fuel Filter Failures
Occasional · medium severity
Typical onset: 80,000-140,000 mi
Symptoms: No-start condition or extended cranking before start, Loss of power under acceleration or at highway speeds, Engine stalling, especially when fuel tank below 1/4, Whining noise from rear of vehicle (fuel tank area)
Fix: Fuel pump assembly replacement requires dropping fuel tank (2.5-3.5 hrs). The inline fuel filter clogs prematurely on higher-mileage units. Some techs report contamination issues from tank rust in northern climate vehicles.
Estimated cost: $500-900
Transmission Mount Failure
Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Clunking noise during shifts or acceleration, Vibration felt through shifter or center console, Excessive drivetrain movement visible when shifting from Park to Drive
Fix: The upper transmission mount (torque strut) tears from engine torque and age. Replacement is straightforward (1-1.5 hrs) but requires supporting the powertrain.
Estimated cost: $200-400
Headlight and Brake Light Wiring Harness Issues
Occasional · medium severity
Symptoms: Headlights or brake lights intermittently not working, Melted or burnt connector at bulb socket, Brake lights stuck on (draining battery), Multiple bulb replacements not solving the issue
Fix: Wiring harness connectors at tail lights and headlights fail from heat and corrosion. GM recall 14V421 addressed brake light wiring. Repair involves replacing pigtail connectors or entire harness sections (1-2 hrs labor per side).
Estimated cost: $150-500
Owner tips
Change transmission fluid every 50,000 mi and inspect oil cooler lines for seepage — catching coolant contamination early saves the transmission.
On V6 engines, use quality full-synthetic oil and change every 5,000 mi maximum to extend bearing life.
Budget for electric power steering failure on any G6 over 80,000 mi — it's not if, but when.
Check for open recalls on steering and brake lights before purchase; many were never completed by prior owners.
Avoid unless under 60,000 miles with documented transmission cooler replacement and all recalls completed — too many expensive, platform-wide failures waiting to happen.

ELECTRICAL SYSTEM:WIRING · 14V252000
2014-05-14 · EA13005
General Motors LLC (GM) is recalling certain model year 2004-2012 Chevrolet Malibu vehicles manufactured May 16, 2003, through October 11, 2012, 2004-2007 Malibu Maxx vehicles manufactured June 25, 2003, through April 5, 2007, 2005-2010 Pontiac G6 vehicles manufactured May 26, 2004, through January 4, 2010, and 2007-2010 Saturn Aura vehicles manufactured April 24, 2006, through May 26, 2009. In the affected vehicles, increased resistance in the Body Control Module (BCM) connection may result in voltage fluctuations in the Brake Apply Sensor (BAS) circuit. These fluctuations can cause one or more of these conditions: the brake lights to illuminate without the brake pedal being pushed; the brake lights to not illuminate when the pedal is pushed; difficulty disengaging the cruise control; moving the gear shifter out of the 'PARK' position without pushing the brake; and disablement of crash avoidance features such as traction control, electronic stability control, and panic braking assist features.
Consequence: Any of the above failure conditions increases the risk of a crash.
Remedy: GM will notify owners, and dealers will attach the wiring harness to the BCM with a spacer, apply dielectric lubricant to both the BCM and harness connector and the BAS and harness connector, and will relearn the brake pedal home position, free of charge. The manufacturer distributed an Interim letter to customers on July 14, 2014. The recall began on August 18, 2014. Owners may contact General Motors customer service at 1-800-222-1020 (Chevrolet), 1-800-762-2737 (Pontiac), 1-800-553-6000 (Saturn). GM's number for this recall is 13036.
POWER TRAIN:AUTOMATIC TRANSMISSION · 14V224000
2014-04-30 · EA11015
General Motors LLC (GM) notified the agency on April 29, 2014, that they are recalling 56,214 model year 2007 and 2008 Saturn Aura vehicles. On May 22, 2014, GM increased the recall to include an additional 1,074,899 model year 2004-2008 Chevrolet Malibu vehicles manufactured from May 16, 2003, through October 5, 2007, model year 2004-2007 Malibu Maxx vehicles manufactured from June 25, 2003, through April 5, 2007, and model year 2005-2008 Pontiac G6 vehicles manufactured from May 26, 2004, through September 28, 2007, and equipped with 4-speed transmissions. The total number vehicles being recalled is now 1,131,113.
Consequence: If the transmission shift cable fractures while the vehicle is being driven, the transmission gear selection may not match the indicated gear and the vehicle may move in an unintended or unexpected direction, increasing the risk of a crash. Furthermore, when the driver goes to stop and park the vehicle, despite selecting the PARK position, the transmission may not be in PARK. If the vehicle is not in the "PARK" position there is a risk the vehicle will roll away as the driver and other occupants exit the vehicle or anytime thereafter. A vehicle rollaway increases the risk of injury to exiting occupants and bystanders.
Remedy: GM will notify owners, and GM dealers will replace the shift cable assembly and mounting bracket, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact General Motors at 1-800-553-6000. GM's number for this recall is 14152.
