Reliability problem analysis

The Subaru Ascent, with a total of 879 complaints, lacks detailed component-specific problem data, making it challenging to pinpoint specific areas of concern. In contrast, the Mazda CX-9 has 252 complaints with identifiable issues, notably in the engine category, which accounts for 95 complaints. The CX-9 also has several crash-linked complaints, particularly concerning the air bags with four incidents and other components like the service brakes, power train, and steering, each linked to crashes. This data suggests the Mazda CX-9 has significant safety-related concerns that are traceable to specific components, unlike the Subaru Ascent, whose problem specifics remain unclear.

Which one to buy

If you prioritize a higher reliability score and fewer recalls, the Mazda CX-9 might be the better choice for you. With a reliability score of 76/100 and only six total recalls, it offers a more dependable ride than the Subaru Ascent. However, keep in mind the CX-9's annual repair cost is estimated at $539, and there's a 10% risk of major repairs, which means you should be prepared for potential maintenance expenses.

On the other hand, if you prefer a model with fewer owner complaints relative to sales, consider the Subaru Ascent. It has fewer complaints per 10,000 sold (9.2) compared to the CX-9's 15. While the Ascent has a slightly lower reliability score of 69/100 and a higher number of recalls (16), it doesn't have any identified top issues, providing peace of mind regarding specific problem areas. Choose the Ascent if complaint frequency and issue transparency are your main concerns.

Cost of ownership

Independent repair cost data indicates that the Mazda CX-9 has an annual repair cost of $539, with an average of 0.6 repair visits per year and a 10% risk of major repairs. Unfortunately, specific data for the Subaru Ascent is unavailable, making direct comparisons challenging. However, the Mazda CX-9's relatively low repair frequency and moderate major repair risk suggest it is a reliable choice.

For cost-conscious buyers, the Mazda CX-9 presents a predictable maintenance profile with clear cost expectations. Without comparable data, it's difficult to assess the Subaru Ascent's value, but the Mazda CX-9's transparency in maintenance costs makes it an attractive option for budget-focused ownership.
