![]() The whole system was still in its early stages, and development is ongoing even today. It seems more likely that, during this era (when CVTs were becoming more widely used), there would be more complaints. These facts are hard to verify since they’re based on submitted owner reviews. The Honda Odyssey, Accord, and Civic often come up. Many sources suggest that the problem time for Honda CVT reliability was the late 90s and early noughties. What Honda Models Are Known For Poor CVT Reliability? A modern Honda Accord. It’s also why most are paired with batteries in a hybrid. Towing or hauling with them is a big no-no. That’s why you don’t see CVTs on most 4x4s or trucks. It depends on the pulleys and the belt, which is a fragile system. Practically, the biggest problem with CVTs is that they can’t transmit much torque. And the noise of old models! Even when they’re working, the incessant droning is worse than listening to a political debate on repeat. In real life, though, CVTs aren’t perfect. ![]() It doesn’t have to cycle through the gears, making it much more effective. In theory, CVTs mean the engine can quickly adjust to road conditions. In other words, it’s “always variable” or “continuously variable.” This means the gear ratio between the input and output can always be adjusted. The belt will always sit securely (in theory!) as the pulley width varies. A wide belt sitting on the outside of the “bowls” will sit higher or lower as they get further away or closer together. As the bases of these two bowls get closer, the gap between them decreases. ![]() Think of each side like an upside-down bowl. By simultaneously adjusting the width of each pulley using sheaves, the ratio can be changed. One of these pulleys is the input the other is the output. The most common type of CVT for the passenger car industry is the Pulley-And-V-Belt model.Ĭontinuously Variable Transmissions work using two conical pulleys and a connecting steel V-belt. ![]()
