The Consumers' Association published a critical report on the C5 in the June issue of its magazine Which?, concluding that the vehicle was of only limited use and represented poor value for money. All three of the C5s that it tested broke down with a "major gearbox fault" and their High-Vis Masts snapped. The longest run between battery charges was only 14.2 miles (22.9 km), and a more realistic achievable range was 5–10 miles (8–16 km).
