No matter whether you plan to buy or own a Mitsubishi ASX, you need to be aware of the problems associated with these cars. It is possible to minimize the damage if you are aware and address critical issues that arise frequently. With its affordable price, safety features, and stylish design, the Mitsubishi ASX has become incredibly popular among consumers.
My goal is to explain the potential issues in this article, to explore their causes and solutions, to explain which Mitsubishi ASX years to avoid, as well as how to inspect a used Mitsubishi ASX before purchasing it. So, let’s take a comprehensive look at these issues.
Mitsubishi ASX Problems
Based on the Mitsubishi ASX owner’s reviews, I will explain common issues the ASX owners have encountered multiple times. New Mitsubishi models are very unlikely to develop critical problems. That is due to their optimal and reliable performance at that time. It is normal for the car components to exhibit faults, errors, and malfunctions after covering a distance of 155,000 to 186,000 miles.
Engine Performance Problems
A common complaint reported by ASX owners is bad engine performance, caused by a variety of factors, including abnormal noises, overheating, bad air filters, cooling system problems, and a bad catalytic converter. Timely replacement or repair of engine components is required over time. The health of an engine can be affected by some components that become faulty. Below are some examples of engine-related problems that are commonly encountered:
- Damaged oxygen sensors: Engine performance is dependent on oxygen sensors because they aid the ECU in adjusting the air-fuel mixture. In the event that one goes wrong, the engine control unit may be unable to perform properly and engine problems may occur.
- Excessive oil consumption: Some ASX owners notice their fuel consumption has increased abruptly. In addition to oil leaks and a bad fuel pump, poor fuel quality, a faulty throttle body, and clogged fuel injectors, there are other factors that contribute to excessive oil consumption.
- Engine stalling: The Mitsubishi ASX can also experience stalling when starting. After prolonged use, stalling can occur as a result of poor lubrication and electrical faults.
Solutions
As long as Mitsubishi ASX owners maintain their vehicles properly and repair any damage promptly, they will encounter fewer engine-related issues. When fuel consumption suddenly increases, inspect the piston rings and valve seals, if necessary, to ensure they are replaced or repaired promptly. To ensure your engine runs smoothly and efficiently, we recommend having it serviced regularly by a mechanic who has a deep, advanced understanding of the engine.
Transmission Issues In Mitsubishi ASX Problems
There are many complaints from Asx owners concerning transmission issues such as acceleration problems, gear slippage, clunking sounds, delayed drive, and sudden loss of power. In the event of a transmission failure, severe engine damage can occur, as well as complex, expensive repairs. Here are some common complaints
- Shuddering and jerking: Due to worn belts or pulleys, the continuously variable transmission (CVT) shakes and shudders when the motor is started. In case of continuous shuddering, internal transmission components may be damaged.
- Overheating: The ASX transmission system can overheat if its temperature constantly increases. The vehicle will automatically switch into limp mode when this happens, which reduces the engine’s power, which can have a negative effect on its performance.
- Gear slippage: The most common reason for gear slippage in Mitsubishi ASXs is a faulty clutch. When shifting from parking to driving or reversing, this is a critically important safety issue.
Solutions
There are many problems with the Mitsubishi ASX transmission, and it is one of the most difficult ones to resolve and requires a high level of mechanical expertise. Keep the transmission system running smoothly by inspecting it manually and by scanning it with a code scanner under the supervision of an expert mechanic, checking the control module and clutch are working properly, updating the software to the most recent version, and using fresh fluid oils.
Electric And Electronic Issues
In some electric parts of the Mitsubishi ASX, there are also problems with electric and electronic components. Among them are:
- Battery draining: A faulty alternator is usually to blame for a battery draining unexpectedly. In electronic devices, the battery provides current to other components, while the alternator charges the battery.
- Infotainment system glitches: The infotainment system in Mitsubishi ASXs has been criticized by owners for being glitchy. It is reported that the touchscreen can be unresponsive for a short period of time and cannot be used.
Solutions
A mechanic who has experience in resolving electrical faults should be brought in if the battery is draining rapidly and the infotainment system isn’t working properly. A battery will be deeply checked and the terminals will be cleaned to ensure corrosion is not present. Other components of the electric system will also be checked for proper operation. It is recommended to replace a faulty component that cannot be used anymore in order to avoid further issues.
Steering Problems
There have been complaints of issues with steering in Mitsubishi ASX models, including faulty steering boxes, worn hoses, grinding and screeching noises when steering, and loose hose couplings. It is essential to have a functioning steering system in order to travel safely and reliably. These are some issues related to steering systems:
- Hard steering: This is a critical problem caused by low fluid levels in the power steering system, or damaged components within the system.
- Alignment problems: If the wheels are not aligned correctly, the steering wheel vibrates, making steering difficult.
Solutions
The first thing you should do is consult a mechanic about steering problems. It is important to check the alignment of the wheels and check to make sure the Mitsubishi doesn’t vibrate. The hard steering issue can be fixed by checking the steering fluid level and filling it to the mandatory level. The smooth rotation of the steering wheel is made possible by the fresh fluid, which keeps it lubricated.
Air Conditioning Problems
You can drive comfortably in hot weather if your air conditioner is properly functioning. Air conditioners on some ASX models deliver inadequate cooling. The interior temperature of a vehicle becomes very uncomfortable when the vehicle is not cooled sufficiently in hot weather.
Performance of an air conditioner can be reduced for a number of reasons.
- Compressor issues: The AC may not function properly when the compressor is faulty. The common symptoms that indicate that a compressor is malfunctioning include weird noises, lukewarm air, ECU errors, and oil leaks.
- Refrigerant leaks: When refrigerant levels become low due to leaks or long periods without changing, cooling will be reduced.
Solutions
Ensure that the compressor is working properly and that there are no refrigerant leaks. The installation of a new one is highly recommended if anything is worn or showing signs of wear and tear.
