2010 Mitsubishi Eclipse

The 2010 Mitsubishi Eclipse is a sporty coupe and convertible known for its stylish design and affordable price point. Engine options include a 2.4L inline-4 producing 162 horsepower and 162 lb-ft of torque and a 3.8L V6 generating 265 horsepower and 262 lb-ft of torque. The inline-4 is paired with either a 5-speed manual or a 4-speed automatic transmission, while the V6 comes with a 6-speed manual or a 5-speed automatic. People generally like the Eclipse’s aggressive styling, comfortable front seats, and decent handling. Downsides often cited are the limited rear passenger space, subpar fuel economy (especially with the V6), and some cheap interior plastics.

Summary

The 2010 Mitsubishi Eclipse can be a fun and stylish car, but potential buyers should be aware of some common issues. Engine issues such as oil consumption and misfires can be costly to repair. Transmission problems, especially with the automatic transmissions, are another area of concern. Suspension and electrical problems are also present but are not as severe. Addressing these issues before they escalate can save money in the long run. The severity of the issues ranges from minor annoyances to potentially expensive repairs. Overall, pre-purchase inspection by a trusted mechanic is highly recommended.
