2017 Ford C-Max

The 2017 Ford C-Max is a hybrid hatchback that offers a blend of fuel efficiency and practicality. It comes in two main variants: the C-Max Hybrid and the C-Max Energi (plug-in hybrid). Both models are equipped with a 2.0-liter four-cylinder gasoline engine paired with an electric motor and a continuously variable transmission (CVT). The combined output is 188 horsepower and 129 lb-ft of torque. Owners generally appreciate the C-Max for its excellent fuel economy, comfortable ride, and spacious interior. However, some common complaints include a smaller cargo area than expected due to the battery pack, a somewhat sluggish acceleration, and the continuously variable transmission can be noisy and lead to issues over time.

Electric Motor

Electric Motor (Both Hybrid and Energi)

• High Voltage Battery Degradation
  • Description/Symptoms: Reduced electric-only range, increased reliance on the gasoline engine, error messages related to battery performance, and reduced overall fuel economy.
  • Solution: Battery replacement or individual module replacement within the battery pack.
  • Estimated Cost to Fix: $3,000 - $8,000+ (depending on whether the entire battery pack or individual modules are replaced)
  • Recalls: None Found

Transmission

Continuously Variable Transmission (CVT) - Both Hybrid and Energi

  • Solution: Transmission replacement.
  • Estimated Cost to Fix: $3,500 - $5,500+
  • Recalls: None Found
• Torque Converter Failure
  • Description/Symptoms: Shuddering at low speeds, difficulty accelerating, and abnormal vibrations.
  • Solution: Torque converter replacement.
  • Estimated Cost to Fix: $1,500 - $2,500+
  • Recalls: None Found

Suspension

  • Recalls: None Found

Summary

The 2017 Ford C-Max can be a fuel-efficient and practical vehicle, but potential buyers should be aware of some common issues. The most concerning are related to the high voltage battery degradation, CVT transmission failures, and Inverter Coolant Pump Failure, which can be costly to repair. Other problems like suspension bushing wear and infotainment glitches are less severe but still worth considering. Thoroughly inspect the vehicle and inquire about the maintenance history, especially related to the hybrid system and transmission, before making a purchase.
