2019 Mazda CX-5 Reliability Score & Common Problems

Owners report several issues with the vehicle speed control in the 2019 Mazda CX-5. A common problem involves unexpected deceleration, often occurring when attempting to accelerate quickly, such as merging into traffic or when using cruise control around curves. Some owners experience a sudden loss of speed to as low as 20 mph, with at least one case linked to a possible coolant leak. Another issue includes unexpected acceleration from a stop, requiring the driver to apply the brakes multiple times to regain control. These problems are reported across various mileage ranges, with some incidents occurring as early as 1,800 miles. Safety implications include sudden braking or acceleration that could lead to potential collisions, particularly in traffic or on highways.

Owners of the 2019 Mazda CX-5 frequently report issues with the air bag warning light, which either illuminates or blinks without apparent cause. Complaints often describe these symptoms occurring around 38,000 miles, with some owners experiencing unresolved issues despite dealer visits. One report includes a crash where the airbag failed to deploy during an incident of unintended acceleration, raising potential safety concerns. Another complaint mentions a persistent "Passenger Air Bag is not active" warning, initially resolved under warranty but recurring after the warranty period expired. These patterns suggest that prospective buyers should be aware of potential airbag system malfunctions and the associated safety implications.

Owners of the 2019 Mazda CX-5 frequently report issues related to a recall on the fuel system, specifically citing the unavailability of necessary parts for the repair. Complaints consistently mention that despite receiving recall notifications, parts are not available, and the repair process is delayed. One owner reports a stalling issue at approximately 5,000 miles, which resolved after restarting the vehicle, raising potential safety concerns if the stalling occurs in traffic. No other symptoms or failures are commonly described, and there are no reports of crashes or fires associated with this issue. Prospective buyers should be aware of potential delays in recall repairs and the possibility of stalling without warning.

Owners report that the 2019 Mazda CX-5's forward collision avoidance system can engage unexpectedly, causing hard braking even when there is sufficient space to avoid a collision. Symptoms include rapid deceleration from speeds as high as 65 mph, sometimes without any vehicles or obstacles in the vicinity. Complaints frequently mention this issue occurring both while in cruise control and during lane changes. The incidents often occur at highway speeds, with one report noting the car has been driven for 12,200 miles. These unexpected braking events pose significant safety risks, such as potential rear-end collisions, and have been described as almost causing accidents. Multiple owners indicate that the system's aggressiveness is problematic, and the option to disable it is limited to a single drive cycle.

Owners of the 2019 Mazda CX-5 report issues with cracked cylinder heads leading to oil leaks, with symptoms including smoke, burning odors, and oil stains on driveways. These problems are typically noted at mileages ranging from approximately 26,000 to 89,000 miles. Complaints frequently mention the absence of warning lights, though one owner noted a check engine light. While no crashes or fires are reported, the presence of smoke and burning odors may indicate potential safety risks. Prospective buyers should be aware of these engine issues and consider verifying any related repairs or service alerts.

Owners of the 2019 Mazda CX-5 report several steering-related issues, often accompanied by other system malfunctions. Common symptoms include a violent jerking of the steering wheel, especially at extreme angles, and a sensation of the car being pulled left and right, akin to wind interference, even in calm conditions. These issues are sometimes linked to electronic sensor failures and are reported to occur without warning lights. One incident describes a severe loss of control during hydroplaning, resulting in the vehicle spinning across multiple lanes. These complaints highlight potential safety risks, including unexpected vehicle behavior and loss of steering control, often occurring after battery-related events or during adverse weather conditions.

Owners of the 2019 Mazda CX-5 report issues with the vehicle's braking system, specifically related to malfunctions in the Smart Brake System. Symptoms include unexpected deceleration, shaking, and dashboard warnings indicating multiple brake-related malfunctions. One owner describes an incident where the vehicle slowed and shook without braking input, while another reports a crash due to unexpected acceleration despite brake application. These issues are reported soon after purchase, with one occurring less than 16 hours after acquiring the vehicle, suggesting potential early-life reliability concerns. The presence of a crash highlights significant safety implications, particularly in high-traffic situations.
