Mitsubishi ASX Problems And Solutions [Detailed Guide 2025]

The purpose of this article is to shed light on the potential problems, delve into their causes and solutions, and explain which Mitsubishi ASX years you should avoid buying if you intend to buy a used Mitsubishi ASX. In order to understand the problems comprehensively, let’s take a close look at them.


Mitsubishi ASX Problems

This article explains common issues that ASX owners face multiple times, as described in Mitsubishi ASX owner reviews. Since the car performance is optimal and reliable at that time, there are very few chances of critical problems occurring in new Mitsubishi models. In the past few hundred thousand to eighty thousand miles, the components of the car have begun to exhibit faults, errors, and malfunctions.

Mitsubishi ASX Problems

Engine Performance Problems

A number of ASX owners have complained about poor engine performance, associated with unusual noises, overheating, bad air filters, cooling system issues, and damaged catalytic converters. It is necessary to replace or repair the engine’s components on a regular basis over time. As some components wear out, they affect the health of the engine as a whole. Following are some engine-related problems that are commonly encountered:

  • Damaged oxygen sensors: The ECU uses oxygen sensors to adjust the air-fuel mixture, which helps maintain engine performance. It is possible for them to become faulty and disrupt the engine control unit’s function, which can cause engine problems.
  • Excessive oil consumption: The fuel consumption of many ASX owners suddenly increases. Several factors contribute to excessive oil consumption, including oil leaks, faulty throttle bodies, clogged fuel injectors, a bad fuel pump, and poor fuel quality.
  • Engine stalling: The Mitsubishi ASX can also have an engine stalling problem when it is starting. During long periods of use, stalling may occur due to electrical problems or lack of lubrication.

Solutions

The Mitsubishi ASX will require less engine-related maintenance and repairs if owners maintain it regularly and promptly repair any damage that occurs. The piston rings and valve seals should be inspected after sudden fuel consumption to determine whether they need to be replaced or repaired, and the service should be performed promptly. Getting regular engine service is always recommended by a mechanic who has deep knowledge of what the engine is and how it works. 

Transmission Issues In Mitsubishi ASX Problems

It is not uncommon for Asx owners to report problems with acceleration, gear slippage, clunking noises, delayed drive, and loss of power when the vehicle suddenly stops. In the case of transmission problems, the engine damage can be severe and the repairs can be complex and expensive. We’ve compiled a list of common complaints.

  • Shuddering and jerking: The continuously variable transmission (CVT) shakes and shudders when it is started by turning the ignition switch on. It is possible for transmission internal components to be damaged by continuous shuddering.
  • Overheating: The transmission system can overheat on some ASX models due to constant temperature increases. As a result of this condition, the limp mode will automatically activate, resulting in loss of power, which impacts the performance of the entire engine.
  • Gear slippage: A faulty clutch is at the root of most gear slippage experienced by Mitsubishi ASX owners. When changing from parking to driving or reverse, this critical safety issue can delay engagement.

Solutions 

There are many Mitsubishi ASX transmission problems, and they can be difficult to resolve and require advanced engineering skills to repair. In order to keep the transmission system in top shape, expert mechanics should inspect it manually and use error code scanners to monitor the condition. Also, ensure that the control module and clutch are operating correctly, update the software to the latest version, and use fresh fluid oils.

Electric And Electronic Issues

In addition to these problems, several electric parts in Mitsubishi ASX have electrical and electronic problems. Among them are:

  • Battery draining: In most cases, a faulty alternator is the cause of an unexpected battery draining. Alternators charge batteries, which supply current to other electronic components. The battery is the most important part of the electric system.
  • Infotainment system glitches: Mitsubishi ASX owners frequently complain about infotainment system glitches. There are reports that the touch screen becomes unresponsive for a short period of time, preventing any action on it.

Solutions 

Consult a mechanic with expertise in resolving electrical problems if your battery drains rapidly and the infotainment system fails to function properly. In addition to thoroughly inspecting the condition of the battery, he will make sure the terminals are corrosion-free, and he will diagnose other electrical components as well. Whenever possible, replace faulty components to avoid further issues.

Steering Problems

Owners of the Mitsubishi ASX have reported problems with steering, including faulty steering boxes, worn hoses, and grinding or screeching noises when steering. It is imperative that the steering system is functioning accurately in order for a journey to be reliable and safe. The following items are explained in relation to steering systems:

  • Hard steering: This is a critical issue that occurs when the fluid in the power steering system gets low, or when a component is damaged or broken.
  • Alignment problems: Unaligned wheels make the steering wheel vibrate, which makes controlling the vehicle difficult.

Solutions 

For steering issues, you should first consult a mechanic. The wheels of the Mitsubishi should be aligned properly, and the vehicle should not vibrate. The hard steering problem can be fixed by checking the fluid level and filling it according to the manufacturer’s specifications. Keeping the steering lubricated and smooth helps keep it in good working order.

Air Conditioning Problems

Air conditioners play an important role in keeping you comfortable while you drive, especially during hot weather. Some ASX models experience insufficient cooling as a result of their air conditioners. During hot weather, maintaining the vehicle’s interior temperature is difficult without adequate cooling.

Several factors can reduce the efficiency of an air conditioner.

  • Compressor issues: If the compressor malfunctions, the AC may not function properly. An ill-functioning compressor is marked by odd noises, cold air, ECU errors, and oil leaks.
  • Refrigerant leaks: When the refrigerant levels are low due to leaks or not changing for a long time, the cooling system’s efficiency is affected.

Solutions 

Ensure that the compressor is in good working order and that there are no leaks of refrigerant. A worn out or worn out component must be replaced and replaced with a new one.


Mitsubishi ASX Years To Avoid

Due to a high volume of complaints from owners using certain Mitsubishi ASX models, some models are identified as having a greater number of problems than others. In case you are buying a Mitsubishi ASX, here’s what you can avoid:

Model YearCommon Issues
2011A problem with the transmission, excessive oil consumption, or an electrical problem
2012Issues with the CVT, transmission, engine stalling, and transmission stalling
2013Misfiring engines, failures of CVT transmissions, premature wear of brakes
2014Problems with electrical systems, CVTs, and excessive oil consumption
2015A suspension problem, a transmission problem, and paint and interior wear are all possible causes
2016Problems with the air conditioning and infotainment systems, premature wear of various components

Conclusion

Despite its many appealing features and advanced technologies, Mitsubishi ASX is generally a highly reliable SUV. Mitsubishi ASX owners also experience problems while taking advantage of the vehicle’s features, just as they do with other vehicles. It will be easier for you to find used Mitsubishi ASX faults that are electrical faults, steering issues, engine performance problems, transmission issues, or air conditioner problems after understanding the errors that occur with Mitsubishi ASXs.

Having a basic understanding of common ASX problems will prove helpful whenever you are suddenly confronted with a technical issue. Be proactive about maintaining your vehicle’s performance by being informed and following the services on a regular basis.
