My Saturn ion has a few weird glitches. First the service engine light is always on, and it asks to check coolant for almost 3 years and all mechanics tell me that the coolant level is fine. But I have no way of knowing if there is a problem until I notice a change in preformance or strange sounds. This time, it's the noise that is getting to me. The sound of the engine is deeper and louder (almost sounds like a when you change road surfaces but loader) When accelarating it reaches a higher pitch before returning to the load rumble (jet engine is my best description) The last couple of days I feel a slight vibration in the brake pedal when slowing down. Suggestion by some well meaning but untrained people have ranged from tires to transmission to timing belt. Any ideas?
