The Saturn Aura emerged through Saturn division at GM from 2007 to 2009 as a successor to Saturn L-Series with the purpose of battling European import competition. The Production model Saturn Aura departs from the assembly lines with a front-engine layout that is mounted transversely and operated by front-wheel drive through the LZ4 3.5 L VVT V6 engine (base XE) or the 3.6 L DOHC V6 power unit (XR versions). Owners can choose between the 3.5L LZ4 V6 (224 horsepower/220 lb-ft torque) engine which powers XE models and the 3.6L DOHC V6 (252 horsepower/251 lb-ft torque) engine reserved for XR models of the Saturn Aura. Initially the XE and XR available versions used a 4T45-E four-speed automatic transmission before the introduction of 6-speed automatic transmission for the XR models alone. The Saturn Aura XR trim level comes standard with a 3.6L DOHC V6 engine which receives high efficiency and performance from its 6-speed automatic transmission system. The suspension of Saturn Aura combines comfort and stability in a system that uses independent front suspension with a multi-link rear setup. The Saturn Aura offers seating for five passengers in the XE model equipped with 16-inch steel wheels whereas the XR trim includes 18-inch aluminum wheels to enhance its visual appeal. Original Saturn Aura components remain dedicated to factory performance criteria which enables long-lasting vehicle reliability together with durability. The Saturn company dedicated its manufacturing period to building a sedan which combined operational excellence with fashionable design characteristics for consumers.
Saturn Aura owners commonly see issues in engine thermal control, valve timing management, and evaporative emissions. In thermal control, the Aura may display A/C off for engine protection and a cold gauge. A worn thermostat sticks open, delaying warmup and storing P0128. Replace the thermostat, bleed air, confirm gauge movement, and verify heater output on the Aura. In valve timing control, the Aura can log P0011, P0014, and related correlation codes. Erratic cam timing may follow excess end play or a weak camshaft position sensor on Saturn models. Update the PCM when applicable, then confirm timing targets with scan data on the Aura. If correlation drifts, inspect oil quality, filter condition, and cam phaser screens per Saturn guidance. In emissions management, the Aura may illuminate a light after refueling. A loose or cracked gas cap allows vapor leaks and sets small leak EVAP codes. Install a new gas cap, clear codes, and complete a full drive cycle. Use Saturn service procedures to check connector seals, harness routing, and thermal learn resets. Finish with a road test so the Aura warms quickly, idles smoothly, and meets monitors.
