One problem related to loud engine noise has been reported for the 2007 Saturn Aura. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2007 Saturn Aura based on all problems reported for the 2007 Aura.
The vehicle has been in and out of repair for the same problem, engines have been replaced but no solution has been found. When driving around 60mph the engine would stall and �engine power reduced� and �traction off� would flash, reducing the car speed and making acceleration near impossible- sometimes multiple times in one trip. Car accelerates very slowly and causes traffic buildup. Rpm is at 5 (x1000)/min at just 30mph and the engine is making loud noises. Sometimes when stalled or at a red light the engine will cut out completely and the car will die. Almost consistently the car will rattle and shake in a pulsing matter. As previously mentioned I have brought it in to local repair shops and no one has been able to find a solution. Often times the engine is replaced but the problem comes back after a couple weeks.
