These include overheating, slipping, jerking, shuddering and a sudden loss of acceleration.
In some extreme cases, owners filed lawsuits against automakers because of poor and unreliable CVT performance. These pulleys are designed to vary in diameter depending on power demand, increasing and decreasing in size inversely of each other. There’s a concern about the longevity of these transmissions due to some past issues in some models of Jeep and Nissan.
That’s why many hybrid vehicles come with CVTs. Toyota recently implemented this theory into its latest CVT, installing a first gear for accelerating from a stop. In practice, the increasing number of speeds in conventional automatics (up from four or five just a few years ago to as many as 10 speeds today) means the fuel consumption advantage with a CVT is small. Then, a Dutch company called DAF produced small cars with a CVT, which they called the Variomatic. The letters CVT surely cause dismay in the hearts of most gearheads.
