Mitsubishi ASX Years to Avoid (2011-2018): Complete Guide

When considering a used Mitsubishi ASX, it’s essential to know the Mitsubishi ASX years to avoid. Models from 2011 to 2018 are known for issues like engine stalling, excessive oil consumption, and CVT transmission failures, leading to costly repairs. 

pecific regional concerns, such as engine belt failures in Australia, electrical component malfunctions in Malaysia, and brake issues in the UK, further complicate the decision-making process. Understanding these problems and their solutions can save buyers from recurring maintenance headaches and ensure a smoother ownership experience.

What Does ASX Stand For?

ASX stands for “Active Sports Crossover”, a name that reflects its blend of sporty handling and SUV practicality.

• The Mitsubishi ASX sits below the Outlander in Mitsubishi’s SUV lineup, making it a more compact and city-friendly option.
• It shares its GS platform with the Mitsubishi Lancer and Outlander, meaning it has similar engineering but in a smaller package.
• In recent years, the European version of the ASX (2023 onward) has been a rebadged Renault Captur, while a second-generation ASX is expected by 2025.

Major Problems in Mitsubishi ASX Models

While newer Mitsubishi ASX models have improved in reliability, older models tend to develop significant functional issues over time. Many owners report that after driving 155,000 to 186,000 miles, problems commonly appear in the engine, air filter, and transmission system, leading to a decline in performance.

Some of the most common issues include:

• Engine oil problems: Can lead to low oil levels and engine damage if not addressed.
• Malfunctioning Fuel Sensor: Causes inaccurate fuel readings, leading to unexpected stalls.
• Excessive Oil Consumption: Requires frequent top-ups and may indicate deeper engine issues.
• Transmission Fluid Leaks: Affects gear shifting and overall driving smoothness.
• Electrical System Failures: Includes alternator problems, battery drain, and faulty wiring.
• Worn-Out Ball Joints: Leads to poor handling and suspension issues.
• Faulty Steering Pump: Makes steering difficult, increasing the risk of accidents.

Major Mitsubishi ASX Problems and Solutions

While the Mitsubishi ASX is a reliable compact SUV for many, certain model years (2011-2018) have experienced recurring mechanical and electrical issues. Below, we’ll break down the most common problems reported by owners and provide practical solutions to keep your ASX running smoothly.

1. Engine Issues

Many ASX owners have faced engine-related problems, ranging from excessive oil consumption to overheating and oil leaks. These issues can lead to reduced engine performance, increased fuel consumption, and costly repairs.

Common Engine Problems

• Excessive oil consumption: Increased fuel usage is often linked to fuel pump malfunction.
• Oil leaks from faulty gaskets and seals
• Overheating due to cooling system malfunctions
• Oxygen sensor failure can cause poor fuel efficiency and engine malfunctions.
• Engine stalling: Due to electrical circuit issues and insufficient lubrication, especially in older models

Solutions

• Monitor oil levels regularly, checking every 1,000 miles
• Replace faulty oxygen sensors when the check engine light appears
• Maintain the cooling system with scheduled coolant flushes every 60,000 miles
• Replace worn gaskets and seals at the first sign of oil leaks
• Update engine management software if available from dealer

2. Transmission Problems (CVT & Manual)

The costly repair of the transmission system in Mitsubishi is very problematic for ASX owners. One of the biggest complaints about the Mitsubishi ASX (2011-2018) is its CVT (Continuously Variable Transmission) issues. Many owners report jerking, overheating, and complete transmission failure. Manual versions aren’t immune either, with some suffering from gear slipping and clutch wear.

Common Transmission Problems:

• CVT jerking and hesitation: A continuous CVT shudder occurs due to excessive pressure on the belt and pulleys, leading to a decline in engine efficiency.
• Overheating: Incomplete combustion raises the temperature, causing the transmission system to overheat.
• Gear slipping, making it difficult to drive smoothly
• Delayed response when shifting gears

Solutions:

• Change transmission fluid every 30,000 miles (more frequently than Mitsubishi’s recommendation).
• Software updates to fix CVT tuning issues
• Professional servicing if you notice slipping, jerking, or overheating

3. Electrical System Failures

Electrical faults are another frustrating issue in some ASX models, affecting everything from the battery to the infotainment system, especially during long drives or in cold weather. Some of the most frequent battery-related problems are:

Common Electrical Problems:

• Battery drain as the alternator wears out, the battery drains faster, leading to poor performance of electronic components.
• Faulty alternator, causing charging system failures
• Infotainment system glitches, like frozen screens and unresponsive touch controls

Solutions:

• Battery and alternator inspections to ensure proper charging
• Software updates for infotainment system bugs
• Check wiring connections if experiencing electrical failures, as mentioned in resources like fuel injection system.

4. Steering & Suspension Issues

The steering and suspension system on some ASX models can develop problems over time, making driving less comfortable and less safe. However, many Mitsubishi ASX owners report faulty steering boxes, damaged hoses, unusual noises while turning, and difficulty with gear engagement.

Common Steering & Suspension Problems:

• Faulty power steering pumps, making it harder to steer and this happens due to low lubrication and inadequate steering fluid levels.
• Worn-out ball joints and control arms, leading to vibrations
• Unstable handling and alignment issues, the steering wheel and vehicle wheels may not be properly synchronized, making it hard to maintain control and causing alignment issues.

Solutions:

• Check power steering fluid level and condition every 15,000 miles
• Inspect suspension components during regular service intervals
• Perform wheel alignment annually or after hitting significant potholes
• Replace worn components at first sign of unusual handling or noise

5. Air Conditioning & Interior Comfort Problems

Another common complaint from Mitsubishi ASX owners is air conditioning failures and infotainment malfunctions, making long drives uncomfortable and  leading to poor cooling and lukewarm air output, making driving uncomfortable, especially in hot weather.

Common AC & Interior Issues:

• AC compressor failure, if you notice oil leaks or receive an ECU error notification, the compressor may need replacement.
• Refrigerant leaks, causing the AC to blow warm air
• Touchscreen freezing, making infotainment unusable

Solutions:

• Have A/C system inspected annually before hot weather season
• Recharge refrigerant when needed and check for leaks
• Keep infotainment system software updated
• Run A/C system regularly, even in winter, to maintain component lubrication
