Some Saturn Ion owners report experiencing issues such as oil light activation, which may include warning messages like "A/C off for Engine Protection" along with the check engine light and a cold temperature gauge. Additionally, high oil consumption is a common concern, with some owners needing to add a quart of oil every 1,000 miles due to failing oil control rings or valve seals. Rough idling or stalling, particularly in cold weather, has also been reported, potentially linked to sensor malfunctions or fuel delivery problems. Furthermore, while specific performance issues related to the crankshaft and bearings are not detailed, owners are advised to promptly address any unusual noises, vibrations, or performance concerns to prevent further engine damage. It is essential for Saturn Ion owners to remain vigilant and resolve these issues quickly to maintain their vehicle's longevity and performance.
