While the engine and transmission can experience issues like oil leaks, coolant leaks, and transmission slippage, these are often repairable. Suspension components like ball joints and tie rods are common wear items. Electrical gremlins, particularly with power windows and the instrument cluster, are also noted. The exterior and interior generally hold up well, with no widespread critical failures reported. Overall, the Aerio can be a reasonably reliable vehicle if potential issues are addressed promptly, but it’s not without its common problems, especially as it ages.
