How the Age of a Car Model Affects its Reliability

Vehicles are an essential part of our lives, and choosing the right one may significantly determine the overall satisfaction of a vehicle owner. One of the determining factors for a satisfactory vehicle ownership experience is reliability. This article examines how the age of a car model affects its reliability, using service call data per 10,000 sold units of four different car models: Toyota Corolla, Honda Civic, Ford Focus, and Chevrolet Malibu.

Overview of Service Calls

By analyzing the number of service calls made per 10,000 vehicles sold across the ages (0-13 years) of these four car models, it becomes clear that the models present a unique pattern of reliability across their ages.

Reliability Comparison Between the Car Models

When examining the service calls made for the Toyota Corolla, the graph shows that newer models (0-3 years) have a relatively high number of service calls. However, the number steadily decreases as the car ages. Honda Civic presents a similar pattern, though with a slightly higher number of service calls for newer models. This trend might signify common issues with newer models that need service attention early in their ownership.

In contrast, the Ford Focus has an incredibly high number of service calls in newer models. The number peaks at around the second year of the car's age and then starts a gradual decline. This pattern may suggest possible manufacturing design problems that require immediate attention in the early years of ownership.

The Chevrolet Malibu has a unique trend where the number of service calls initially grows until the fifth year and then gradually decreases. This trend denotes perhaps a vehicle design requiring high maintenance during its 'adolescent' years.

Technical Explanation for the Results

Early models' high service numbers in Toyota, Honda, and Ford may be attributed to the teething problems commonly experienced with new car models, such as minor electrical and mechanical faults or recalls for parts replacements. On the other hand, the swift peak in Ford Focus's service calls could point towards more serious, inherent design issues in parts of the car such as the drivetrain, cooling, or fuel systems.

As for the Chevrolet Malibu, the reliability graph might point towards the common reliability-bath-tub-curve concept. This concept shows that the number of faults or service calls usually grows during a car's early life, becomes stable in the middle, and then rises again towards the end of its life. Malibu's stability in the number of service calls during its early life, followed by an increase and then gradual decrease, could be because of this concept.

Conclusions

Reliability is a significant deciding factor while purchasing cars and is directly influenced by the age of the car model. As shown by service call statistics, a car's reliability could shift drastically from its initial years to its later years on the road. It thus becomes imperative for vehicle owners to understand these reliability curves when buying and maintaining their cars. Besides, manufacturers also must work towards reducing these service calls, as they reflect on the vehicle's quality and hence the brand's reputation.

Ultimately, by understanding these patterns, both manufacturers and car owners can work towards an improved vehicle ownership experience. Given the long-term investment that a vehicle represents, making informed decisions on a vehicle's reliability across its age could significantly aid in enhancing value for money.
