The 2008 Malibu represents the first year of GM's mid-size renaissance, but early production units suffer from catastrophic 2.4L engine failures, transmission cooler line leaks, and electric power steering faults that leave this generation as a risky used buy without comprehensive service records.
Symptoms: Burning 1+ quart of oil every 500-1,000 miles with no external leaks, Blue smoke from exhaust on startup or acceleration, Check engine light for misfires (P0300-P0304), Sudden loss of power, knocking, or complete seizure
Fix: Piston ring land failure dumps oil into combustion chambers. Requires complete engine rebuild or replacement. Short block replacement takes 14-18 hours; full rebuild 20-25 hours. Many shops won't rebuild due to core design flaw—recommend reman or junkyard replacement.
Estimated cost: $4,500-7,500
Transmission Oil Cooler Line Leaks & Radiator Contamination
Common · high severity
Typical onset: 60,000-110,000 mi
Symptoms: Pink or milky ATF leaking near radiator lower tank, Transmission slipping, delayed engagement, or shuddering, Strawberry milkshake appearance in coolant overflow, Overheating transmission followed by engine overheating
Fix: Steel cooler lines corrode where they enter plastic radiator end tanks, allowing ATF and coolant to mix. Requires radiator replacement, external cooler installation, complete trans flush (or replacement if contaminated badly), and both cooler lines. Radiator/lines alone: 3-4 hours. Add 2-3 hours for trans service, 12-16 if trans is toast.
Estimated cost: $800-1,200 (if caught early); $3,000-4,500 (if trans damaged)
Electric Power Steering (EPS) Failure
Occasional · high severity
Typical onset: 80,000-150,000 mi
Symptoms: Power steering cuts out intermittently or completely, Service power steering message on DIC, Heavy steering effort at low speeds or complete manual steering, No warning—just instant failure while driving
Fix: Motor brushes wear or control module fails in the steering column assist unit. GM issued TSBs and recalls, but many units outside coverage fail. Replacement EPS column assembly required (no rebuild option from GM). 2.5-3.5 hours labor. Alignment check recommended after.
Estimated cost: $800-1,400
Transmission Range Sensor & PRNDL Display Issues
Occasional · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: Gear indicator shows wrong gear or flashes, Won't start in Park—have to jiggle shifter, Starts in gear other than Park (rollaway risk), Check engine light with P0708, P0847 codes
Fix: Transmission range sensor on valve body wears or internal shifter cable/linkage loosens. External adjustment sometimes works temporarily. Sensor replacement requires pan drop, valve body access. 2-3 hours labor. Related recall for some VINs, check before paying.
Estimated cost: $350-650
Timing Chain Stretch (3.6L V6)
Occasional · high severity
Typical onset: 100,000-150,000 mi
Symptoms: Cold-start rattle for 2-3 seconds from front of engine, Check engine light with P0008, P0017, P0018 (cam/crank correlation), Rough idle, misfires, poor performance, Catastrophic failure: bent valves if chain jumps
Fix: Early 3.6L High Feature engines use inferior timing chains and guides. All four chains, guides, tensioners, cam phasers, and water pump should be replaced together. Front-wheel-drive V6 timing set: 12-16 hours labor. Not a DIY job. Preventive replacement at 100k advised.
Estimated cost: $2,800-4,200
Crankshaft Position Sensor Intermittent No-Start
Common · medium severity
Typical onset: Any mileage
Symptoms: Intermittent no-start, cranks but won't fire, Stalling while driving, restarts after sitting, No check engine light or P0335/P0336 code stored, Heat-related—fails when engine hot, works when cool
Fix: Sensor behind starter (2.4L/3.6L) or at front crank (2.2L) fails from heat cycling. Replacement straightforward but starter removal adds time on some engines. 1-2 hours labor. Always replace connector pigtail if corroded.
Estimated cost: $180-350
Owner tips
Check oil every 500 miles on 2.4L engines—if consumption exceeds 1 qt/1,000 mi, walk away or budget for engine replacement immediately
Inspect radiator end tanks and trans cooler lines at every oil change; pink residue is a deal-breaker
3.6L V6 buyers: demand timing chain replacement records or negotiate $3k off asking price
Test electric power steering thoroughly during test drive—cycle lock-to-lock at idle and low speed
Avoid 2008-2009 build dates if possible; 2010+ received running changes that improved some (not all) issues
Pass unless you find a meticulously-maintained unicorn with engine replacement records, fresh timing chains (V6), and zero trans cooler history—this generation is a minefield for the unprepared buyer.

Dorman Products, Inc. (Dorman) is recalling certain replacement intermediate steering shafts sold under the Dorman, OE Solutions, and Solutions brand names, part numbers 425-167, 2425167, and 7-3074, for installation on 2004-2012 Chevrolet Malibu, 2005-2010 Pontiac G6, and 2007-2009 Saturn Aura vehicles. The affected steering shafts may have a yoke that inadequately supports the u-joint bearing resulting in a premature failure.
Consequence: A joint bearing that fails prematurely may cause separation of the u-joint resulting in a complete loss of steering control, increasing the risk of a crash.
Remedy: Dorman will notify owners, and dealers will refund the purchase price or replace the steering shafts, free of charge. The recall began in September 2014. Owners may contact Dorman customer service at 1-800-523-2492.
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.
STEERING:ELECTRIC POWER ASSIST SYSTEM · 14V153000
2014-03-31 · EA11014
General Motors LLC (GM) is recalling certain model year 2004-2006 and 2008-2009 Chevrolet Malibu, 2004-2006 Malibu Maxx, 2009-2010 HHR (non-turbo), 2010 Cobalt, 2008-2009 Saturn Aura and 2004-2007 Ion, and 2005-2009 Pontiac G6. In the affected vehicles, there may be a sudden loss of electric power steering (EPS) assist that could occur at any time while driving.
Consequence: If power steering assist is lost, greater driver effort would be required to steer the vehicle at low speeds, increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will perform one of four bulletins. Parts are not currently available. GM expects to send an interim notification around May 28, 2014. When parts are available, owners will be mailed a second letter to come in to have the applicable bulletin applied. Bulletin 14115 covers model year 2004-2007 Saturn Ion, 2009-2010 Chevrolet HHR and 2010 Chevrolet Cobalts. Dealers will replace the EPS motor. Bulletin 14116 covers model year 2004-2006 Chevrolet Malibu and Malibu Maxx, 2005-2006 Pontiac G6 and 2008-2009 Chevrolet Malibu, Pontiac G6 and Saturn Aura built from March 1, 2008, through June 27, 2008. Dealers will replace the torque sensor assembly. Bulletin 14117 covers model year 2008 Chevrolet Malibu, Pontiac G6 and Saturn Aura built from February 1, 2008, through February 28, 2008. Dealers will replace the torque sensor assembly and EPS motor controller unit. Bulletin 14118 covers model year 2008 Chevrolet Malibu, Pontiac G6 and Saturn Aura built from October 1, 2007, through January 31, 2008. Dealers will replace the EPS motor controller unit. The recall began on July 17, 2014. Owners may contact Chevrolet at 1-800-630-2438, Saturn at 1-800-553-6000, and Pontiac at 1-800-620-7668. GM's number for this recall is N140115. Note: GM bulletin number 14119 will be implemented for model year 2006-2008 and early production of 2009 Chevrolet HHR (non-turbo) and model year 2003 Saturn ION to provide EPS Motor replacement for the life of the vehicle.
POWER TRAIN:AUTOMATIC TRANSMISSION:GEAR POSITION INDICATION (PRNDL) · 12V460000
2012-09-18
General Motors (GM) is recalling certain model year 2007-2010 Saturn Aura and model year 2008-2010 Chevrolet Malibu and Pontiac G6 vehicles, equipped with a 4-speed automatic transmission. On these vehicles, the tabs on the transmission shift cable end may fracture and separate.
Consequence: If the tabs were to fracture and separate, the shift lever and the actual position of the transmission gear may not match. The driver would be able to move the shifter to 'PARK' and remove the ignition key, but the transmission gear may not be in 'PARK.' The vehicle may not be able to be restarted and the vehicle could roll away after the driver has exited the vehicle, resulting in a possible crash without prior warning.
Remedy: GM will notify owners, and dealers will install a retainer over the cable end or replace the shift cable as necessary. This service will be performed free of charge. Notification to owners began on on November 9, 2012. Owners were instructed to not bring their vehicles for repair until January 2013. Owners may contact General Motors at 1-800-521-7300.
