Is the First Mazda CX-5 Worth It? Here’s What Goes Wrong

Mazda’s CX-5 has long been considered a top contender in the compact SUV segment, praised for its sleek design, agile handling, and solid reputation for reliability. But for those considering a used Mazda CX-5 first generation, there are several overlooked issues that could make ownership more expensive—and frustrating—than expected.

Experts Identify Key Weak Points

According to automotive expert Alexander Vinogradov, contributing to the Russian auto journal Za Rulem, the first-generation Mazda CX-5 has a handful of recurring problems that tend to appear after moderate use. Most of them are tied to core engine components and vehicle electronics, leading to higher maintenance costs and potential downtime if not addressed early.

Start-Stop System Battery: A Costly Vulnerability

One of the most frequently reported issues lies with the start-stop system battery, which is known to wear out prematurely. While start-stop features are designed to improve fuel economy, they demand more from the battery than traditional systems. In the Mazda CX-5, this often results in early battery failure, leading to inconsistent engine restarts and, in some cases, unexpected shut-offs.

Moreover, the battery malfunction can accelerate the wear and tear of drive belts and pulleys, increasing the chance of mechanical breakdowns if replacements are not made promptly.

Ignition System Troubles Raise Operating Costs

For models equipped with gasoline engines, Vinogradov points to weak ignition coils as a significant issue. These parts tend to fail sooner than expected, triggering check engine lights and performance issues.

To make matters worse, Mazda recommends only OEM spark plugs, which are significantly more expensive than generic alternatives. Over time, this can add up, especially for drivers who follow regular tune-up intervals.

Not All Costs Are Obvious Upfront

One of the more frustrating aspects of these issues is their tendency to remain hidden during test drives or initial inspections. In many cases, buyers of used Mazda CX-5 models only discover these faults after a few months of ownership—when warranties may no longer apply.

Given the rising costs of OEM parts and labor, the vehicle’s low purchase price can become deceptive. What seems like a bargain upfront may turn into a long-term investment in repairs.

What Are the Alternatives?

Auto analyst Sergey Zinoviev suggests that those seeking reliability at a similar price point might consider the Hyundai Tucson third generation, but only specific variants. Turbocharged models and those with dual-clutch transmissions are best avoided due to gearbox and overheating issues.

Instead, he recommends choosing the naturally aspirated 2.0-liter G4NA engine, paired with either a manual or traditional automatic transmission. This configuration, he notes, can run for over 250,000 km without major mechanical failures—something not easily claimed by first-gen CX-5s.

Final Take: Stylish but Demanding

The Mazda CX-5 first generation still appeals to many with its athletic stance, high-quality cabin, and road dynamics. However, as more owners report recurring mechanical and electrical faults, it’s clear that some aspects of the vehicle may not live up to Mazda’s reputation for reliability.

Prospective buyers are strongly advised to perform a full diagnostic check before purchasing a used unit and budget for higher-than-average maintenance costs—especially related to the start-stop system and ignition components.

If long-term dependability is a top priority, there may be better options in the same segment—offering peace of mind without the added surprise of unforeseen repairs.
