Part 4/9:
Another major factor contributing to the longevity issue is the evolution of engine designs. Gone are the reliable, naturally aspirated engines that powered vehicles in the past, replaced by smaller, turbocharged, and more complex engines. Whereas old V6 engines offered robust torque and reliability, modern engines often contain intricate components that work too hard, generating excess heat and leading to inevitable failures.
Consequently, these engines necessitate more frequent oil changes and maintenance. The increased complexity and sensitivity of modern engines mean they lack the resilience of earlier designs. As a result, once the warranty expires, the risk of expensive repairs escalates dramatically.
