Disadvantages of the Toyota C50A gearbox
- The robot received negative reviews and quickly gave way to automatic transmission in many markets.
- The first control unit often malfunctioned and a recall campaign was carried out in 2009.
- The clutch caused the most problems; it failed after 50,000 km.
- Expensive electromechanical actuators were not particularly reliable.
