2018 Ford C-Max

The high-voltage hybrid battery pack degrades over time, causing reduced fuel economy, loss of electric-only driving range, and eventually a 'Stop Safely Now' warning that disables the vehicle. Some owners report the battery failing as early as 80,000-100,000 miles. The C-Max Energi plug-in version experiences more rapid degradation in hot climates.

Ford warranted the hybrid battery for 8 years/100,000 miles (10 years/150,000 miles in CARB states). If within warranty, the dealer will replace the battery pack free of charge. Out of warranty, consider a remanufactured battery pack from a specialist. Individual cell replacement may be possible at lower cost.

The electronically controlled continuously variable transmission (eCVT) develops a shudder or vibration during acceleration, particularly when transitioning between electric and gasoline power. Some owners report a harsh clunk when the gasoline engine engages, and the transmission may hesitate before accelerating from a stop.

Have the dealer reprogram the hybrid control module and transmission control module with the latest calibration. Ford issued TSBs addressing the engagement harshness. Check the transmission fluid level and condition. If internal damage is present, the eCVT may need rebuild or replacement.

The regenerative braking system on the C-Max causes inconsistent brake pedal feel, with the pedal sometimes feeling spongy and other times grabbing harshly. Front brake rotors warp prematurely, causing a pulsating pedal during conventional braking. The transition between regenerative and friction braking is not seamless.

Replace warped front rotors and brake pads. Have the dealer recalibrate the regenerative braking system blend with the friction brakes. Inspect the brake hydraulic system for air intrusion, which is common in hybrid vehicles with complex brake systems. Use OEM-spec rotors for best results.

The 2013-2016 C-Max is included in Ford's massive door latch recall. The door latch pawl spring tab can fracture, preventing the door from staying closed. This is particularly dangerous on the C-Max because the hatchback design means a rear liftgate latch failure can also occur.

Ford issued recalls 15S27 and 16S36 to replace all affected door latches with an improved design. Contact your dealer to verify your VIN. The repair is free of charge.

The 2.0L Atkinson-cycle engine's internal heat exchanger can leak coolant into the transmission fluid. This cross-contamination turns the transmission fluid pink or milky and damages internal clutch packs and seals. If not caught early, both the engine cooling system and transmission suffer catastrophic damage.

If coolant contamination is detected early, flush the transmission thoroughly and replace the internal cooler. If the transmission has already been damaged, a full rebuild or replacement is necessary. Monitor transmission fluid color during regular maintenance. Replace the engine coolant-to-transmission heat exchanger.

Ford Motor Company (Ford) is recalling certain 2013-2019 Escape, 2013-2018 C-Max, 2013-2016 Fusion, 2013-2021 Transit Connect, and 2015-2018 Edge vehicles. The bushing that attaches the shifter cable to the transmission may degrade or detach.

A damaged or missing bushing may prevent the vehicle from shifting into the intended gear, and cause the vehicle to move in an unexpected direction. Additionally, the vehicle may roll after the driver selects the 'Park' position. Either scenario increases the risk of a crash or injury.

Dealers will replace the under hood shift bushing and add a protective cap over the shift cable bushing, free of charge. Interim owner notification letters, informing owners of the safety risk, were mailed July 1, 2022. Remedy parts are expected to be available in 4th Quarter 2022. Owner notification letters were mailed October 27, 2022. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 22S43.
