The 2008 Saturn Aura is a mid-size sedan built on GM's Epsilon platform sharing DNA with the Malibu. While decent when maintained, it's plagued by catastrophic 2.4L engine failures, transmission issues, and electrical gremlins that make it a risky used buy.
Symptoms: Rattling on cold start that disappears after warm-up, Check engine light with timing-related codes (P0008, P0011, P0014), Sudden loss of power and catastrophic internal damage, Metal shavings in oil, Engine runs rough or won't start
Fix: The 2.4L timing chain stretches due to inadequate oiling of the tensioner. Once stretched, it jumps teeth and destroys pistons, valves, and bearings. Early catch requires timing chain, guides, tensioner, and VVT actuators (8-12 hours labor). Most owners discover it too late and need complete engine replacement or rebuild (18-25 hours). This is THE killer issue on the 2.4L—seen it take out engines at 90K with religious oil changes.
Estimated cost: $1,800-3,500 for timing components; $4,500-7,000 for used engine swap or rebuild
Symptoms: Shudder or vibration during light acceleration at 30-50 mph, Slipping between gears, especially 2nd-3rd, Delayed engagement when shifting to Drive or Reverse, Transmission overheating, Burnt transmission fluid smell
Fix: The 4T45E transmission suffers from torque converter clutch material breakdown and internal pressure control solenoid issues. Fluid changes can mask it temporarily but rarely fix it. Proper repair requires transmission removal, rebuild with updated torque converter and pressure control solenoids (12-16 hours). Used transmissions are gambles—most are already compromised. The external cooler lines also corrode and leak, requiring replacement during any major trans work.
Estimated cost: $2,800-4,200 for rebuild; $1,800-2,800 for used trans swap
Electric Power Steering (EPS) Column Failure
Occasional · high severity
Typical onset: 70,000-140,000 mi
Symptoms: Intermittent power steering loss with warning light, Steering suddenly becomes very stiff, Clicking or grinding noise from steering column, Total steering assist failure without warning, DTC C0545 or C0550
Fix: GM's early EPS systems have motor and control module failures inside the steering column. This was recalled on some VINs but not all—check yours. When it fails, you lose all assist (manual steering returns, but it's a workout). Replacement requires removing the column, installing a remanufactured unit, and programming (4-6 hours). Aftermarket units exist but quality varies—OEM remans are safest.
Estimated cost: $800-1,400
Engine Coolant Leaks from Water Pump & Outlet Housing
Common · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Coolant smell in cabin or engine bay, Visible coolant drips under front of engine, Low coolant warning light, Overheating in severe cases, Coolant residue on timing cover
Fix: Both the 2.4L and 3.5L develop water pump seal leaks and plastic coolant outlet housing cracks. On the 2.4L, the pump is behind the timing cover, requiring significant disassembly (5-7 hours). The 3.5L pump is easier (2-3 hours). Always replace the thermostat housing and hoses at the same time—they're plastic and brittle by this age. Catching this early prevents overheating damage.
Estimated cost: $500-900 for V6; $800-1,300 for I4
PRNDL Shift Indicator & Shifter Cable Issues
Occasional · medium severity
Typical onset: 80,000-140,000 mi
Symptoms: Gear indicator on dash doesn't match actual gear, Cannot shift out of Park even with brake pressed, Car starts in wrong gear position, Shifter feels loose or disconnected, Key stuck in ignition
Fix: The shift position sensor and shifter cable bushing wear out, causing misalignment between shifter position and transmission. This was subject to a recall (10V388000) but many weren't fixed. Repair involves replacing the shift cable assembly and recalibrating the park lock system (2-3 hours). The ignition interlock also fails, preventing key removal—separate but related issue requiring BCM programming.
Estimated cost: $350-650
Electrical Issues: BCM, Wiring Harness Corrosion
Occasional · medium severity
Symptoms: Random warning lights (ABS, traction control, airbag), Gauges going haywire or dropping to zero, Windows, locks, or radio intermittent, No-start with no crank, Battery drain overnight
Fix: Body Control Module failures and corroded harness connectors plague these cars, especially in salt states. The BCM under the dash fails from heat and vibration, causing bizarre electrical symptoms. Diagnosis requires scanning multiple modules and checking grounds (1-3 hours diagnosis). BCM replacement requires programming (2-3 hours total). Harness corrosion at bulkhead connectors requires tracing and repairing individual circuits—labor-intensive.
Estimated cost: $400-800 for BCM; $200-600 for harness repairs
Owner tips
If buying a 2.4L, absolutely demand evidence of timing chain replacement or walk away—this engine is a ticking time bomb after 80K miles
Change transmission fluid every 50K with full synthetic Dexron VI—won't prevent failure but buys time
Check for steering recall completion (10V388000 and 14V153000)—many weren't done and EPS failure is dangerous
Inspect coolant level religiously and look for pink residue around timing cover—early leak detection prevents overheating catastrophe
Have a pre-purchase inspection scan all control modules—electrical issues are expensive rabbit holes
Hard pass unless you find a meticulously maintained 3.5L V6 with documented timing chain work on a 2.4L—too many expensive grenades waiting to detonate for the money you'll save buying one.

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.

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.
