2012 Kia Optima
Here’s a breakdown of common issues and complaints associated with the 2012 Kia Optima, categorized and formatted as requested.
The 2012 Kia Optima was a popular mid-size sedan known for its stylish design, fuel efficiency, and value. It was available with three engine options: a 2.4L inline-4 producing 200 horsepower and 186 lb-ft of torque, a 2.0L turbocharged inline-4 producing 274 horsepower and 269 lb-ft of torque, and a 2.4L hybrid engine. All non-hybrid engines were paired with a 6-speed automatic transmission. Common praises included the Optima’s comfortable ride and feature-rich interior for the price. Criticisms often centered on the base engine’s performance being adequate but not particularly exciting, and some reported issues with reliability.
