2012 Kia Rio

The 2012 Kia Rio is a subcompact car known for its fuel efficiency, stylish design (for its time), and relatively spacious interior compared to other vehicles in its class. It was available with a 1.6-liter Gasoline Direct Injection (GDI) four-cylinder engine producing 138 horsepower and 123 lb-ft of torque. It came standard with a six-speed manual transmission, but most were equipped with the optional six-speed automatic transmission.

Common complaints include a somewhat firm ride, road noise, and some owners have reported issues with reliability, which is reflected below.

Summary

The 2012 Kia Rio can be an affordable and fuel-efficient choice, but potential buyers should be aware of potential issues. Engine-related problems, especially those concerning excessive oil consumption and knocking, are among the most concerning due to the high cost of repair. Electrical issues, such as the brake light switch and clock spring failures, are also common. While some repairs are relatively inexpensive, engine and transmission problems can result in significant repair bills. It is essential to get a pre-purchase inspection to assess the vehicle’s overall condition and identify any potential problems before buying.
