Whether you're about to buy your first car or upgrading your current ride, it is vital that you make a smart decision that you do not later come to regret. Choosing a vehicle is a very personal thing. A car should complement your lifestyle while fitting within your budget.
While researching different makes and models of vehicles is an essential part of the car-buying process, it is important to keep in mind that some vehicles have serious flaws that in most cases outweigh their overall benefits. Spend some time reading reviews, both online and from trusted sources. While there are many options of cars out there, it is vital to keep in mind that they are not all created equal. Some vehicles feature drivetrains prone to failure.
The most common drivetrain component to suffer a premature failure tends to be the CVT automatic transmission. CVT stands for Continuously Variable Transmission. While these transmissions may offer a marginally better fuel economy, they are predisposed to various faults and excessive wear, causing premature failures.
It’s important to understand that CVTs operate differently from traditional automatic or manual transmissions. They rely on a belt or chain and pulley system to provide an infinite range of gear ratios, rather than fixed gear sets. This design choice, while offering smooth acceleration and fuel efficiency benefits, also introduces specific vulnerabilities.
One major reason for CVT susceptibility to failure is due to excessive heat and wear caused by the friction that occurs as the belt or chain runs between two pulleys to convert the power from the engine to power applied to the wheels. Due to the fact that the CVT transmission allows a certain amount of level of slip between the belts and the pulleys during hard acceleration or when moving from a complete stop, it introduces additional stress on moving parts. Over time, CVT components can wear down, especially when introduced to stop-and-go city driving. The belt or chain material can degrade due to heat, friction, and normal wear, leading to slippage or breakage. Additionally, the pulleys and idler pulleys have moving parts that require precise alignment and lubrication and any misalignment or lack of proper maintenance can cause premature wear.
