Which one to buy

If you prioritize a vehicle with lower owner complaints and fewer recalls, the KIA K5 might be your ideal choice. It has a slightly lower complaint rate of 10.2 per 10,000 sold compared to the Subaru Legacy's 21.2. Additionally, the K5 has slightly fewer recalls with 20 compared to the Legacy's 19. However, keep in mind that the K5's major issues are related to the electrical system, power train, and fuel system.

On the other hand, if predictable repair costs and frequency are more important to you, consider the Subaru Legacy. Independent repair cost estimates suggest an annual cost of $563, with a repair frequency of 0.3 times per year and a 12% risk of major repairs. Its main issues include visibility and the electrical system, which might be less concerning depending on your driving habits and conditions.

Cost of ownership

According to industry estimates, the Subaru Legacy has an annual repair cost of $563, with an average of 0.3 repair visits per year and a 12% risk of major repairs. Unfortunately, specific repair data for the KIA K5 isn't available, but this lack of information can be a concern for buyers who value transparency in ownership costs. While the Subaru Legacy's repair frequency and major repair risk are quantifiable, the absence of such data for the KIA K5 makes it challenging to compare directly. For cost-conscious buyers, the Subaru Legacy might represent better value due to its clear and predictable maintenance profile.
