“The coolant low warning light displayed. The first time this happened, we topped of the coolant. Within 1 month it was displaying again. We took the car to the dealer. They attributed the problem to a loose clamp. They replaced the clamps. They also replaced a belt because the coolant had been dripping onto it causing it to degrade. Within 2 months, the light came on again. We took the car back to the dealer. This time they replaced all of the hoses.”
