Final answer:
Free yearly maintenance checks can extend the life of a car's engine and do not void warranties; they are often required for warranty validity. These maintenance checks can apply to new cars and are subject to the terms provided by the dealer and manufacturer.
Step-by-step explanation:
When considering free yearly maintenance checks for a car engine, it is important to understand the implications and benefits connected to such services. One notable point is that free annual maintenance checks can extend the life of the engine by ensuring that it is running correctly and that any issues are addressed promptly.
While it may be true that warranties cover various aspects of a new car for a certain period, generally, maintenance checks do not void these warranties unless they are not performed according to the manufacturer's specifications. Rather, regular maintenance is often required to keep the warranty valid. However, the availability of these free checks can vary and may apply only to new cars; it largely depends on the dealer and manufacturer offers at the time of purchase.
Thus, it is critical to read the warranty terms and understand what is and isn't covered, and whether or not the free yearly maintenance checks apply to your vehicle, be it new or used.
