Common Isuzu MU-X Problems & Reliability Issues: Guide 2025

The Isuzu MU-X (Multi-Utility Crossover) is a 5-door famous mid-size SUV produced in 2013. It has gained a strong reputation due to its durability, versatility, off-road capability, and reliable performance. However, the Isuzu MU-X has some flaws, just like other vehicles.

However, this article explores some of the most common Isuzu MU-X problems and reliability issues and how they can affect your Vehicle’s reliability, health, and performance. Moreover, I’ll provide some preventive measures and maintenance tips you should follow. 

Introduction Of The Isuzu MU-X

The Isuzu MUX was introduced in 2013, and it has been a good choice for adventure seekers, families, and people looking for a robust vehicle designed to handle various driving conditions. Strong towing capacity and spacious interior make it appealing to the consumer’s eye.

The Isuzu MU-X is available in 4×2 and 4×4 configurations, powered by a reliable diesel engine that delivers a strong performance without sacrificing fuel economy. Along with these advantages, several problems surfaced that are of concern among owners. Promptly addressing and fixing these issues can help maintain the Vehicle’s performance and lifespan. 

Isuzu MU-X Problems And Reliability Issues

According to the reports and expert auto reviews, here are the common Isuzu MUX problems and reliability issues experienced by the drivers:

• Engine problems
• Transmission issues
• Suspension and ride quality issues
• Electrical and sensor problems
• Brake and steering concerns 
• Rust and corrosion

Engine Problems

For the Isuzu MU-X owners, the engine problems are one of the main concerns, especially in diesel models with the diesel particulate filter (DPF). Drivers frequently driving in urban environments complain that the DPF can become clogged over time. They normally observe a need for DPF regeneration, as indicated by the dashboard warning lights.

This condition leads to a significant increase in the fuel consumption. However, these issues can affect your driving experience and Vehicle’s effectiveness. The premature turbocharger failure is the second that relates to the engine. When encountering this issue on their vehicles, the drivers may experience a whining noise during acceleration.

However, this can cause a vehicle to exhibit a power loss, usually at high speed and excessive exhaust smoke. All these signs show that the turbocharger is not working optimally, causing poor performance. 

Transmission Issues: One From Main Isuzu MU-X Problems

The transmission issues are another concern in vehicles. Some MU-X owners complain about their automatic transmission models’ rough or jerky gear shifts. This problem often becomes more transparent at low-speed driving, where gear changes should be smooth and seamless.

As an alternative, drivers may observe a jarring motion during gear shifting, which leads to a poor driving experience. Furthermore, transmission overheating is noticed in such conditions as long trips and vehicles under heavy towing scenarios. However, an overheating warning light on your Vehicle’s dashboard will show the presence of that issue.

In some cases, transmission overheating can cause visible transmission fluid leakage, which indicates a potential internal issue. All these transmission problems can affect the driving, leading to poor engine performance.

Suspension And Ride Quality Issues

A suspension system is built into the Isuzu MU-X vehicles to tangle with off-road conditions. A very common issue owners report is the harsh ride quality, especially when driving on rough surfaces. Suspension in vehicles enhances their off-road capabilities, but the ride feels jarring on highways or city streets. 

Over time, some suspension parts, such as the bushings, shock absorbers, and control arm, may wear out, causing uncomfortable rides. Therefore, after the breakdown of these components, the drivers may start to feel knocking or unusual noises, particularly when they drive over bumps or potholes.

Uneven tire wear is the second sign that refers to suspension wear, decreasing the effectiveness of the Vehicle’s handling. As it affects the vehicle’s off-road capabilities, it can especially concern drivers commonly driving in rugged terrains.

Electrical And Sensor Problems

Isuzu MU-X and other modern vehicles have several electrical systems and sensors that help manage crucial things like engine performance. MU-X owners have reported some issues with electrical systems (especially with certain sensors). However, the dashboard warning lights and abnormal engine behavior are some symptoms that result in these problems.

In some instances, due to faulty sensors, some major Vehicle safety systems, such as airbags and anti-lock brakes (ABS), may not work properly. This can create a concern for drivers as safety systems are crucial to any vehicle’s reliability. 

The Vehicle’s infotainment system is another common electric issue. A few owners have encountered problems with system instability, unresponsiveness, or performance issues, especially those with touchscreen interfaces. These glitches can create difficulty in controlling navigation audio, Bluetooth connectivity, or other essential features.

Sometimes, the system may reboot or fail randomly to connect devices, which can be frustrating for drivers who want convenience during travel from these features. Therefore, electrical and sensor issues are also involved in the Isuzu MU-X problems and can lead to more critical faults if they are not addressed and solved promptly. 

Brake And Steering Concerns

Not for MU-X only, the braking performance is crucial for any vehicle in the market. Some MU-X drivers have complained about brake noises and vibrations.

This can be alarming if the noise is associated with a pulsing sensation in the brake pedal. While this issue may not affect your braking system immediately, you should take immediate action to avoid more big trouble.

After brakes, some MU-X drivers have also reported steering problems. This issue can create difficulty maintaining a straight line and become more prominent when driving at high speeds or on uneven roads. This issue also contributes to faster tire wear and misalignments and is particularly reported by drivers who commonly travel long distances. 

Rust And Corrosion

The issues with rust and corrosion are also included in the common Isuzu MU-X problems reported by owners, especially on the underbody and certain exterior areas of their vehicles. The regions with high salty air and humidity or areas where road salt is frequently used in winter are more common reasons for that issue. 

Over time, the corrosion can affect the Vehicle’s structural integrity, particularly if it affects the frame or other critical suspension components. Moreover, the rust spots on the Vehicle’s bodywork directly impact its overall appearance. 

While it may not be visible to the driver immediately, regular inspections can detect its signs early, allowing for timely maintenance before it becomes a critical issue.

Maintenance Tips for Isuzu MU-X Issues

Regular maintenance is the key factor you should adopt to prevent your Vehicle from potential Isuzu MUX problems. However, some of the maintenance are as follows:

• Oil changes: To prevent wear and tear on engine parts, change the engine oil regularly, particularly if you have a diesel model.
• Transmission care: Check and service the transmission promptly to avoid long-term problems.
• Suspension checks: Periodically check the suspension system, especially if you commonly drive on rough terrain.
• DPF maintenance: To ensure proper DPF regeneration, you should regularly drive on the highways.
