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.

On the 2007-2010 Pontiac G6 2.4L Ecotec LE5 / LAT (Hybrid), the 2.4L Ecotec LE5 in 2007-2010 G6 (and shared Cobalt SS, Malibu, HHR, Saturn Aura/Ion, Solstice) develops timing chain stretch — a very well-documented engineering issue across Ecotec forums and independent shops. Root cause: GM's original Oil Life Monitor allowed intervals up to 12,000 miles, starving the chain. Note: while GM issued Special Coverage Adjustment 11340C covering timing chain stretch on the 3.6L LFX/LLT V6, the 2.4L Ecotec did NOT receive the same blanket warranty extension. Some owners obtained goodwill repairs through dealer-level escalation.

This issue also affects: Buick LeSabre, Buick Park Avenue, Buick Cascada

Common Symptoms

  • cold start rattle
  • misfire
  • check engine light
  • reduced power

How to Fix

Full timing chain kit replacement (chain, tensioner, guides) ~$1,200-$2,000. If you experience the issue under 100,000 miles, request a goodwill-assistance review at a GM/Chevy dealer (not all approved, but some are). Use dexos1 full-synthetic 5W-30 and stick to 5,000-mile intervals going forward.

On the 2006-2009 Pontiac G6, the 3.5L 'wet' V6 routes engine coolant through passages in the intake manifold, and the original plastic-framed lower intake manifold gaskets degrade and leak. This causes external coolant loss or, worse, coolant leaking internally and mixing with the engine oil, which can damage bearings and lead to overheating. (The later 3.9L V6 uses a 'dry' intake and is not prone to the same failure.)

Common Symptoms

  • Coolant loss with no obvious external leak
  • Sweet smell / coolant near the manifold
  • Overheating
  • Milky/foamy oil on dipstick or oil cap
  • Low coolant warnings

How to Fix

Replace the lower intake manifold gaskets, ideally with an upgraded metal-framed set (e.g., Fel-Pro). It's a 4-6 hour job; check the oil for a milky appearance before driving as a contaminated engine should not be run.

On the 2006-2010 Pontiac G6, g6 owners frequently see a 'Reduced Engine Power' message with the car dropping into limp mode, triggered by throttle position sensor voltage-correlation faults. The throttle body's integrated TPS develops dirty or shorting solder points (sometimes attributed to 'tin whiskers') and corrosion at the connector, so the two throttle sensor signals disagree and the ECM cuts power for safety.

This issue also affects: Chevrolet Cobalt, Chevrolet Impala, Chevrolet Suburban

Common Symptoms

  • Reduced Engine Power warning message
  • Sudden loss of acceleration / limp mode
  • Hesitation or rough idle
  • Check engine light

How to Fix

Inspect and clean the throttle body and TPS connector; check wiring for corrosion/water intrusion. The common fix is replacing the electronic throttle body assembly; relearn the throttle after replacement.

On the 2005-2010 Pontiac G6, the headlight low-beam (H11/9006) connector on 2005-2010 G6s develops corrosion and high resistance, generating heat that melts the socket and pigtail. Owners report low beams burning out every few months, fuses popping, and visible browned/charred connectors when the bulb is pulled. Affects both sides, but driver's side first.

Common Symptoms

  • Low beam headlight repeatedly burns out
  • Melted/discolored headlight bulb connector
  • Headlight fuse blowing
  • One headlight intermittent or stays out

How to Fix

Replace the melted bulb socket pigtail with a ceramic high-temperature H11 connector kit (14-gauge wire) and pack the new connector with dielectric grease. Inspect both sides even if only one has failed.

On the 2005-2010 Pontiac G6, if you own a 2005-2010 Pontiac G6 built between May 26, 2004 and January 4, 2010, it falls under GM's safety recall 14V252000. The defect is increased resistance in the Body Control Module (BCM) connection, which can produce voltage fluctuations on the Brake Apply Sensor (BAS) circuit. Per NHTSA, one result of those fluctuations is improper brake light operation. Because the problem lies in the electrical connection feeding the BCM and BAS rather than in a single failed component, it is corrected by treating and securing the connectors themselves. The G6 was one of four GM cars swept up in this campaign alongside the Chevrolet Malibu, Malibu Maxx and Saturn Aura; the 2,440,524-vehicle figure NHTSA publishes is the total for the entire campaign, not for the G6 alone. NHTSA rates the consequence as an increased risk of a crash.

Common Symptoms

  • Brake lights not operating properly

How to Fix

Correction is free of charge at a GM dealer. The dealer secures the wiring harness to the BCM with a spacer, applies dielectric lubricant to the BCM harness connector and to the Brake Apply Sensor harness connector, and relearns the brake pedal home position. Owners received an interim letter dated July 14, 2014, with the recall beginning August 18, 2014. Since the G6 line has been discontinued, check the VIN at nhtsa.gov/recalls to see if the remedy is still outstanding, and contact GM customer service at 1-800-222-1020 to arrange a dealer that will perform it.

On the 2005-2010 Pontiac G6, the G6 is notorious for low-beam headlights that burn out or stop working repeatedly. The root cause is that the bulb generates more heat than the cheap plastic headlamp connector/socket can handle, so the connector overheats, melts, and loses contact. Owners often replace bulbs only to have them fail again within months because the connector and wiring are the real problem.

Common Symptoms

  • One or both low beams stop working
  • High beams still work but low beams don't
  • Headlight bulbs burn out every few months
  • Melted/discolored bulb connector
  • Blown headlight fuse

How to Fix

Replace the melted bulb socket/connector pigtail (often sold as a repair harness). A durable fix is upgrading to ceramic or gold-plated soldered connectors. Inspect fuses (commonly 7 and 9) and the headlight switch/wiring for corrosion.

On the 2005-2010 Pontiac G6, the G6's Passlock theft-deterrent system can falsely trip, illuminating the security light and preventing the engine from starting. The common cause is a worn ignition lock cylinder/Passlock sensor that fails to read the lock rotation correctly. The well-known 10-minute relearn trick only resets it temporarily; the fault usually returns until the cylinder/sensor is replaced.

This issue also affects: Chevrolet Impala, Chevrolet Colorado, Chevrolet HHR

Common Symptoms

  • Car cranks but won't start
  • Security/anti-theft (padlock) light on or flashing
  • Intermittent no-start
  • Starts after waiting ~10 minutes

How to Fix

Temporary: turn key to ON and wait ~10 minutes until the security light stops flashing (repeat the relearn cycle as needed). Permanent fix is replacing the ignition lock cylinder / Passlock sensor and relearning the system, sometimes with a fresh dealer key.

On the 2005-2010 Pontiac G6, common G6 fault pattern: simultaneous Service StabiliTrak, Service Traction Control, ABS warning lights, and sometimes Reduced Engine Power message. GM-acknowledged issue (TSB) traced to fretting corrosion on terminals of the Body Control Module connectors (especially the C2 connector) located behind the passenger kick panel. Micro-vibration causes oxidation on the contact surfaces; moisture intrusion from sunroof drains can accelerate it.

This issue also affects: Buick Encore GX, Cadillac XTS, Cadillac Escalade

Common Symptoms

  • Service StabiliTrak and Service Traction Control messages
  • ABS warning light
  • Reduced Engine Power message
  • Intermittent communication codes (U-codes)

How to Fix

Remove the passenger kick panel to access the three large BCM connectors (especially the C2 connector); unlatch via the plastic levers, inspect for green/fretting corrosion, clean with electrical contact cleaner, apply dielectric grease per GM procedure (one-inch nylon bristle brush on C2 pins), and re-seat several times. Note: the 'Reduced Engine Power' message specifically is often caused by a separate IP-to-body harness connector in the DRIVER-side (left) kick panel carrying the APP signal — inspect both sides. Do NOT replace the BCM for this condition. Also scan wheel-speed and steering-position sensors before condemning the BCM.

On the 2008-2010 Pontiac G6, gM recalled 2008-2010 Pontiac G6 sedans and coupes built with the 4-speed automatic transmission because the tabs on the transmission shift cable end can fracture and separate. Once those tabs break, the shift lever in the console no longer reliably reflects what the transmission is actually doing — the indicated gear and the real gear can disagree. The specific hazard NHTSA describes is that a G6 driver can slide the lever into 'PARK' and pull the ignition key out while the transmission is not in PARK at all, so the car is left unsecured after the driver believes it has been parked. This is a defect in the linkage between the shifter and the gearbox, not in the transmission itself, so a G6 that shifts and drives normally can still have it. The campaign covered 426,240 vehicles in total across every model included in the recall; that figure is campaign-wide and is not a count of G6s.

Common Symptoms

  • Gear selected on the shift lever does not match the gear the transmission is actually in
  • Vehicle can move or roll away after the lever has been placed in PARK
  • Ignition key can be removed even though the transmission is not truly in PARK

How to Fix

The repair is free at any Pontiac/GM dealer under recall 12V460000. Depending on what the technician finds, the dealer either installs a retainer over the shift cable end to hold the tabs together or replaces the shift cable outright. GM began notifying owners on November 9, 2012, with repairs starting January 2013, so many G6s have already been done — but the remedy stays free regardless of age or mileage. Enter your G6's VIN at nhtsa.gov/recalls to confirm whether this campaign is still open on your specific car. Until it is repaired, set the parking brake every time you park.

On the 2005-2010 Pontiac G6, on G6 models with the 4-speed automatic, the tabs on the transmission shift cable end can fracture/separate, or the shift cable adjustment clip may not be fully engaged. When this happens the shifter position and the actual transmission gear no longer match, so the driver can move the lever to Park and remove the key while the transmission is not truly in Park. This created a documented rollaway hazard and was the subject of NHTSA recalls 09V073000 and 14V224000.

Common Symptoms

  • Shifter says Park but car can roll
  • Key can be removed while not fully in Park
  • Vehicle rolls away after being parked
  • Shift lever position doesn't match gear
  • Hard to get out of or into Park

How to Fix

Under recall, dealers install a retainer/clip over the cable end or replace the shift cable as necessary, at no charge. Out of recall, the shift cable assembly is replaced. Use the parking brake until repaired.

On the 2006-2009 Pontiac G6, the G6 convertible (2007-2009) uses a complex 2-piece clamshell retractable hardtop with hydraulic rams and multiple position sensors. Hydraulic ram fluid leaks, weak/failed hydraulic pumps, and bad microswitches/latch sensors leave the top stuck halfway, lifting the trunk but failing to clear the windshield, or refusing to deploy at all.

Common Symptoms

  • Top stuck halfway up or down
  • Trunk opens but top will not move
  • Hydraulic fluid puddle in trunk
  • Top operation requires manual assistance
  • Squeaks, creaks, and rattles from roof

How to Fix

Diagnose with a scan tool that reads body module roof codes — most repairs are weak hydraulic pumps ($400-800), leaking rams ($600-1200), or microswitch/latch sensor replacement ($150-400). Keep trunk drain channel clear so a stuck top does not flood the trunk.

On the 2005-2010 Pontiac G6, g6 rocker panels and lower door edges develop severe rust-through, especially in salt-belt states. The rockers are welded into the body sill (not bolt-on), with poor factory undercoating in the seam. Owners report visible holes and crumbling metal by 8-12 years of age. Same pattern as sibling Saturn Aura and Chevy Malibu (Epsilon platform).

Common Symptoms

  • Bubbling paint along rocker panel
  • Rust holes ahead of rear wheel arch
  • Crumbling lower door edges
  • Rust at rear-door bottom corners

How to Fix

Catch early: grind to bare metal, treat with rust converter, prime and topcoat. Advanced cases require cut-and-weld rocker patch panels ($200 per side in parts, ~$1000 body-shop labor). GM's 6-year/100k corrosion warranty has long expired on these vehicles.

On the 2005-2010 Pontiac G6, g6 sedans equipped with the large panoramic (multi-panel) sunroof commonly leak water into the cabin. The frequent culprit is the sunroof drain tubes, which GM cut short, allowing them to pull off their outlets so water drains onto the seat belts, under the rear seat, and into the carpet. Owners also report the motorized sunshade buckling/breaking, panel pins/screws falling out, and the roof getting stuck.

Common Symptoms

  • Water in rear footwell / under rear seat
  • Wet seat belts or headliner
  • Sunshade won't move or buckles
  • Sunroof stuck open or closed
  • Rattles from sunroof panels

How to Fix

Clear and re-secure or replace the sunroof drain tubes so they stay seated at the outlets; repair or replace the sunshade mechanism and any loose panel hardware. Keep drains clear of debris.

On the 2005-2009 Pontiac G6, nHTSA campaigns 14V153000 and 15V064000 together cover affected 2005-2009 Pontiac G6 vehicles for sudden loss of electric power-steering assist. The remedy depends on model year and build window and can involve the torque sensor, EPS motor/controller or applicable bulletin. The campaign-wide 1,373,177 figure is not a G6-only count, and exact sources do not support calling this the single most-complained-about defect or assigning a 70,000-100,000-mile onset.

This issue also affects: Buick LaCrosse, Chevrolet Corvette, Chevrolet Silverado 1500

Common Symptoms

  • sudden EPS-assist loss documented
  • steering warning and DTCs captured
  • VIN and build-window campaign applicability checked
  • current remedy availability and charge confirmed

How to Fix

A sudden loss of assist requires greater steering effort, especially at low speed; reduce speed and stop safely if control is affected. Check the VIN with NHTSA and GM for open campaigns and have codes/build applicability diagnosed before repair. Ask the dealer to confirm current remedy availability and any charge in 2026. Do not buy a torque sensor, column, EPS motor or controller from this page; the applicable bulletin, failed component, part number and VIN fitment must be established first.

On the 2005-2010 Pontiac G6, the sealed front wheel bearing/hub assemblies on the 2005-2010 G6 commonly wear out, producing a loud humming or grinding noise that rises with speed and changes when turning. If a turn to one side worsens the noise, the failing bearing is typically on the opposite side. Left unrepaired, a bearing can seize or fail completely, which is a serious safety risk.

Common Symptoms

  • Humming/growling that increases with speed
  • Noise changes when turning left vs right
  • Grinding from the front end
  • Vibration felt through the floor/steering

How to Fix

Replace the affected front wheel bearing/hub assembly (a bolt-on unit). They are often replaced in pairs; quality units (e.g., Timken/SKF) are recommended.

On the 2005-2010 Pontiac G6, the pressed-on front wheel hub/bearing units on 2005-2010 G6s fail commonly between 70k-120k miles, producing a humming, roaring, or growling noise that increases with speed and changes pitch when turning (load shift to the bad side makes it quieter). Eventually causes ABS light and wheel play.

Common Symptoms

  • Humming or growling noise that worsens with speed
  • Noise pitch changes when turning
  • ABS or traction control light
  • Vibration through steering wheel

How to Fix

Replace the failed bolt-on front hub assembly (DIY-friendly, no press needed). Test by swerving gently at 40-50 mph: noise quieter on right turn = left bearing bad. Use Timken/SKF/Moog for longevity.

What is the 2006-2009 Pontiac G6 Retractable Hardtop Hydraulic Pump and Microswitch Failures?

The G6 convertible (2007-2009) uses a complex 2-piece clamshell retractable hardtop with hydraulic rams and multiple position sensors. Hydraulic ram fluid leaks, weak/failed hydraulic pumps, and bad microswitches/latch sensors leave the top stuck halfway, lifting the trunk but fa… Repairs typically run $400-$2,500. Severity: high.

What is the 2005-2009 Pontiac G6 Sudden loss of electric power steering (EPS) assist?

NHTSA campaigns 14V153000 and 15V064000 together cover affected 2005-2009 Pontiac G6 vehicles for sudden loss of electric power-steering assist. The remedy depends on model year and build window and can involve the torque sensor, EPS motor/controller or applicable bulletin. The c… Severity: high.

What is the 2008-2010 Pontiac G6 Shift Cable End Tabs Fracture — Transmission May Not Actually Be in Park (Recall 12V460000)?

GM recalled 2008-2010 Pontiac G6 sedans and coupes built with the 4-speed automatic transmission because the tabs on the transmission shift cable end can fracture and separate. Once those tabs break, the shift lever in the console no longer reliably reflects what the transmission… Severity: high.

What is the 2007-2010 Pontiac G6 G6 2.4L Ecotec (LE5/LAT) Timing Chain Stretch?

The 2.4L Ecotec LE5 in 2007-2010 G6 (and shared Cobalt SS, Malibu, HHR, Saturn Aura/Ion, Solstice) develops timing chain stretch — a very well-documented engineering issue across Ecotec forums and independent shops. Root cause: GM's original Oil Life Monitor allowed intervals up… Repairs typically run $1,200-$2,500. Severity: high.

What is the 2005-2010 Pontiac G6 Transmission shift cable / vehicle not actually in Park (rollaway)?

On G6 models with the 4-speed automatic, the tabs on the transmission shift cable end can fracture/separate, or the shift cable adjustment clip may not be fully engaged. When this happens the shifter position and the actual transmission gear no longer match, so the driver can mov… Severity: high.

What is the 2006-2009 Pontiac G6 Intake manifold gasket coolant leak (3.5L V6)?

The 3.5L 'wet' V6 routes engine coolant through passages in the intake manifold, and the original plastic-framed lower intake manifold gaskets degrade and leak. This causes external coolant loss or, worse, coolant leaking internally and mixing with the engine oil, which can damag… Repairs typically run $610-$718. Severity: high.

What is the 2006-2010 Pontiac G6 Reduced Engine Power / throttle limp mode (P2135, P0121, P2101)?

G6 owners frequently see a 'Reduced Engine Power' message with the car dropping into limp mode, triggered by throttle position sensor voltage-correlation faults. The throttle body's integrated TPS develops dirty or shorting solder points (sometimes attributed to 'tin whiskers') a… Repairs typically run $250-$500. Severity: high.

What is the 2005-2010 Pontiac G6 NHTSA Recall 14V252000: BCM Connection Resistance Causes Brake Apply Sensor Voltage Fluctuations?

If you own a 2005-2010 Pontiac G6 built between May 26, 2004 and January 4, 2010, it falls under GM's safety recall 14V252000. The defect is increased resistance in the Body Control Module (BCM) connection, which can produce voltage fluctuations on the Brake Apply Sensor (BAS) ci… Severity: high.

What is the 2005-2010 Pontiac G6 Rocker Panel and Lower Door Rust-Through?

G6 rocker panels and lower door edges develop severe rust-through, especially in salt-belt states. The rockers are welded into the body sill (not bolt-on), with poor factory undercoating in the seam. Owners report visible holes and crumbling metal by 8-12 years of age. Same patte… Repairs typically run $200-$1,500. Severity: medium.

What is the 2005-2010 Pontiac G6 Front wheel bearing/hub failure (humming/grinding noise)?

The sealed front wheel bearing/hub assemblies on the 2005-2010 G6 commonly wear out, producing a loud humming or grinding noise that rises with speed and changes when turning. If a turn to one side worsens the noise, the failing bearing is typically on the opposite side. Left unr… Repairs typically run $384-$1,208. Severity: medium.

What is the 2005-2010 Pontiac G6 Front Wheel Hub Bearing Growl/Groan at Highway Speed?

The pressed-on front wheel hub/bearing units on 2005-2010 G6s fail commonly between 70k-120k miles, producing a humming, roaring, or growling noise that increases with speed and changes pitch when turning (load shift to the bad side makes it quieter). Eventually causes ABS light… Repairs typically run $150-$550. Severity: medium.

What is the 2005-2010 Pontiac G6 Low-beam headlights repeatedly fail (melted bulb connector/socket)?

The G6 is notorious for low-beam headlights that burn out or stop working repeatedly. The root cause is that the bulb generates more heat than the cheap plastic headlamp connector/socket can handle, so the connector overheats, melts, and loses contact. Owners often replace bulbs… Repairs typically run $20-$150. Severity: medium.

What is the 2005-2010 Pontiac G6 Passlock anti-theft no-start (security light on)?

The G6's Passlock theft-deterrent system can falsely trip, illuminating the security light and preventing the engine from starting. The common cause is a worn ignition lock cylinder/Passlock sensor that fails to read the lock rotation correctly. The well-known 10-minute relearn t… Severity: medium.

What is the 2005-2010 Pontiac G6 StabiliTrak / Traction Control / ABS Warning from BCM Connector Corrosion?

Common G6 fault pattern: simultaneous Service StabiliTrak, Service Traction Control, ABS warning lights, and sometimes Reduced Engine Power message. GM-acknowledged issue (TSB) traced to fretting corrosion on terminals of the Body Control Module connectors (especially the C2 conn… Repairs typically run $0-$600. Severity: medium.

What is the 2005-2010 Pontiac G6 Panoramic sunroof leaks and mechanical failures?

G6 sedans equipped with the large panoramic (multi-panel) sunroof commonly leak water into the cabin. The frequent culprit is the sunroof drain tubes, which GM cut short, allowing them to pull off their outlets so water drains onto the seat belts, under the rear seat, and into th… Severity: low.
