Mazda CX8 Problems

Are you familiar with the Mazda CX8 problems?

The Mazda CX8 is classified as a Large SUV, comes in eleven variations, and is manufactured in Japan. Customers have a choice between unleaded gasoline and diesel engines.

The car was initially revealed as a Japan-only model, however, Mazda debuted it in Australia in July 2018 and positioned it beneath the somewhat bigger CX-9. The model with three-row seating is offered in two trims.

The first is a seven-seater with a bench in the second row. The second trim is a six-seater with captain’s chairs in the second row and storage space and cupholders in the center console. The CX8 provides 209 liters of luggage capacity with third-row seats in position [1].

Mazda has been producing the CX8 Since 2018. The CX8 is the company’s top-selling vehicle in the United States. Yet there are drawbacks, and customers have complained about a variety of problems with every model.

Engine issues have been topping the list of complaints. Yet, there are still additional problems, such as faulty electrical systems, non-deploying airbags, and steering issues.

Most Common Mazda CX8 Problems


  1. Engine Problems

In general, Mazda CX vehicles are known for having high-quality engines. However, the CX8 version still has a few problems with its engine. Concerns that the engine would not restart after being turned off caused Mazda to recall the diesel CX8 model [2].

Additionally, engine stalling is among the most frequent engine problems mentioned by Mazda CX8 owners. This happens when the engine stalls suddenly. This can be quite risky, particularly on the highway.

The gasoline system issue is one potential factor. If the fuel pump or fuel injectors malfunction, the engine might not receive enough fuel to keep running.

Moreover, a blocked fuel filter can reduce fuel flow and result in engine stalling. Problems with the ignition system might also result in engine stalling.

The engine may suddenly stall due to faulty spark plugs, a broken ignition coil, or a worn-out distributor cap. Similarly, a damaged crankshaft or camshaft position sensor might make it impossible for the engine to start or cause it to stall while running.

Oil leaks are another frequent engine problem that can be brought on by a bad gasket or a damaged oil pan. A broken valve cover gasket is one potential reason why oil leaks occur in Mazda CX8 vehicles.

The valve cover gasket keeps oil from leaking out while sealing the valve cover to the engine block. This gasket may deteriorate, crack, or shrink with time, causing oil to leak [3].

An oil pan that is damaged is another potential reason for oil leaks. Oil leaks can occur when the oil pan, which stores the engine’s oil, is fractured or otherwise harmed by road debris or other impacts.

Moreover, a worn-out or damaged oil filter may be the cause of the oil leak by allowing oil to leak through the filter seal. Another typical engine problem for Mazda CX8 owners is a lack of power, particularly while accelerating.

A trained mechanic or dealership can suggest the best repairs or maintenance after determining the precise cause of the issue. Proper maintenance like oil changes and tune-ups can also aid in preventing problems like engine stalling. You can guarantee that your Mazda CX-8 keeps operating dependably and securely on the road by being proactive and aware of its demands.

  1. Battery Failure

Several Mazda CX8 owners have complained of battery failure. They have noted that the battery is unable to maintain a charge or completely fails to start the car. Aging is a common factor in battery failure.

Batteries typically last three to five years before beginning to lose their charge and become unreliable. Extreme temperatures and other variables can also play a role in battery failure [4].

An unreliable alternator is yet another potential reason for battery failure [5]. When the engine is running, the alternator charges the battery.

Therefore, if the alternator stops working, the battery might not get enough power to function. The headlights may dim as a result of this problem, or there may be other electrical problems.

Battery failure can be avoided with routine maintenance. Inspecting the battery terminals for corrosion and making sure the alternator is working properly are a few of the ways to accomplish this.

A competent mechanic or dealership should examine your battery and charging system to identify the root of the issue and make any necessary fixes.

  1. Dashboard Display Issues

There have also been reports of defective dashboard displays on the Mazda CX8. This problem might make it challenging to keep track of the vehicle’s performance.

Important information like the speedometer, fuel gauge, and warning lights are shown on the dashboard. A broken instrument cluster is one potential reason why the dashboard display isn’t working properly [6].

This part, which regulates the dashboard display, is susceptible to damage from mechanical or electrical problems. The dashboard display flickering or fading, erroneous gauge readings or total failure of the display are all signs that the instrument cluster is broken.

A bad electrical connection is another probable reason why the dashboard display is malfunctioning. The dashboard display may become dysfunctional due to loose or damaged wiring.

Other electrical problems with the automobile, including fading headlights or flickering interior lights, may also be present in conjunction with this problem.

It’s crucial to have your Mazda CX 8’s dashboard display problem evaluated by a certified mechanic or dealership if you’re having problems with it. They can help to identify the cause of the problem and perform the required repairs or replacements.

  1. Power Window Problems

Another frequent electrical problem experienced by Mazda CX8 owners is dysfunctional power windows. This problem may be brought on by several things, including a malfunctioning power window motor, a blown fuse, a broken switch, or a wiring issue.

The fuses should be checked first if your Mazda CX-8’s electric windows aren’t operating. Replace a blown fuse quickly to potentially solve the issue.

If the fuses are not the problem, though, it might be an issue with the switch or the power window motor [7]. The power window motor might need to be replaced if it’s broken. Since this is a more difficult repair, a qualified mechanic should handle it.

  1. Steering Wheel Vibrations

Steering wheel vibrations are among the most frequent problems experienced by Mazda CX-8 owners. The steering wheel will experience these vibrations while driving, which can be brought on by various things.

Unbalanced wheels or tires are one of the causes of steering wheel vibrations [8]. This problem can be resolved by having the wheels and tires balanced by a professional.

Steering wheel vibrations might also be brought on by alignment problems. Vibrations might result from misaligned wheels pulling the steering to one side.

Regular wheel alignment checks are necessary, and any problems should be corrected by a qualified mechanic [9].

Consider having your car inspected by a qualified mechanic to protect the safety and comfort of the driver and passengers. The mechanic will identify the origin of the vibrations and have it rectified as soon as possible.
