Mitsubishi vehicles are known for their reliability, performance, and affordability. Whether you're driving a compact sedan, a crossover, or a full-sized SUV, Mitsubishi cars offer a great balance of value and functionality. However, like any brand, they can experience certain issues over time. Understanding the common problems that Mitsubishi owners face can help you maintain your vehicle properly, avoid expensive repairs, and address issues early.
In this blog, we will look at some of the most common issues reported by Mitsubishi owners and how to address them to keep your car running smoothly.
1. Transmission Problems
Transmission issues are one of the most commonly reported problems with Mitsubishi vehicles, especially with older models like the Mitsubishi Outlander and Lancer. These issues may range from rough shifting to complete transmission failure.
Symptoms:
- Slipping gears
- Harsh or delayed shifting
- Unusual noises when shifting
- The transmission warning light turning on
Causes:
- Low or dirty transmission fluid
- Worn-out transmission components
- Software or sensor malfunctions
How to Fix:
Regularly checking and changing the transmission fluid as part of your maintenance schedule can help prevent these issues. If the transmission is slipping or making unusual noises, it’s important to take your Mitsubishi to a certified mechanic for an inspection and potential repair.
2. Engine Stalling or Misfiring
Some Mitsubishi models have been known to experience engine stalling or misfiring issues, particularly in the Lancer and Outlander series. These problems can occur suddenly, leaving drivers frustrated, and could be a sign of an underlying engine problem.
Symptoms:
- The engine unexpectedly stalls while driving or idling
- Rough idling
- Decreased acceleration and poor fuel efficiency
- Misfire in one or more cylinders
Causes:
- Faulty spark plugs or ignition coils
- Dirty or clogged fuel injectors
- Failing fuel pump
- Dirty air filters or intake valves
How to Fix:
Regular maintenance, including replacing spark plugs and air filters, can help prevent engine misfires. If the problem persists, a diagnostic test should be performed to identify if the Mitsubishi Issues is related to the fuel system or ignition system. Repairing or replacing the affected components should resolve the issue.
3. Electrical Problems
Electrical issues are not uncommon in Mitsubishi vehicles, especially in models like the Eclipse or Outlander. These problems can range from minor glitches in the infotainment system to more serious issues with the vehicle’s power system.
Symptoms:
- Malfunctioning dashboard lights or warning lights
- Unresponsive electrical components (windows, locks, radio)
- Battery not charging or rapid battery drain
- Issues with the alternator
Causes:
- Faulty alternator or battery
- Loose or corroded battery terminals
- Wiring problems or faulty connections
- Malfunctioning sensors or electronic components
How to Fix:
If you experience electrical issues, it’s important to get your Mitsubishi diagnosed as soon as possible. A professional mechanic will likely inspect the battery, alternator, and fuse box to ensure everything is functioning properly. Replacing the faulty component—whether it’s the battery, alternator, or wiring—should restore electrical functionality.
4. Suspension and Steering Problems
Another issue reported in some Mitsubishi models, particularly the Outlander and Lancer, is suspension and steering system malfunctions. These problems can affect your vehicle’s handling, ride comfort, and safety.
Symptoms:
- Unusual noise when driving over bumps or uneven surfaces
- Vibration or steering wheel shaking at high speeds
- Difficulty turning the steering wheel or excessive play
- A rough or uncomfortable ride
Causes:
- Worn-out suspension components (shocks, struts, bushings)
- Leaking power steering fluid
- Misalignment or worn-out steering rack
- Damaged or worn ball joints
How to Fix:
Routine checks of the suspension and steering systems during regular maintenance can help identify problems before they become major issues. If you notice any of the above symptoms, it's essential to have your car’s suspension system inspected. Replacing worn-out parts or realigning the steering system should restore normal performance.
5. Excessive Oil Consumption
Some Mitsubishi models, especially the older Lancer and Eclipse, have been known to experience excessive oil consumption. This can lead to engine wear, decreased performance, and, if left unchecked, engine failure.
Symptoms:
- The oil level drops rapidly between oil changes
- Blue smoke from the exhaust
- Engine knocking or a rough idle
Causes:
- Worn piston rings or valve seals
- Clogged or dirty PCV valve
- Leaking gaskets
How to Fix:
If your Mitsubishi is consuming oil at a rapid rate, it’s important to get the engine checked. The issue may require replacing worn engine components such as piston rings or valve seals. Regularly checking the oil level and performing oil changes as recommended can help prevent long-term damage to the engine.
6. Timing Belt Issues
The timing belt is a critical component in keeping your engine running properly. In some Mitsubishi models, including the 2.4L engine found in the Lancer and Outlander, the timing belt may become worn over time.
Symptoms:
- Unusual noises coming from the engine (such as ticking or rattling)
- Engine misfire
- Difficulty starting the engine
- The engine’s performance decreases drastically
Causes:
- Wear and tear on the timing belt
- Incorrect tension or misalignment of the belt
- Failure to replace the belt at the recommended intervals
How to Fix:
Mitsubishi recommends replacing the timing belt at regular intervals, usually between 100,000 to 150,000 kilometers, depending on the model. Neglecting this maintenance can lead to costly repairs if the timing belt breaks, potentially causing extensive engine damage. Replacing the belt before it becomes an issue is key to avoiding these problems.
7. Brake Problems
Brake issues are another common concern for Mitsubishi owners. Whether it’s worn-out brake pads or malfunctioning brake sensors, these issues can affect your vehicle’s braking performance.
Symptoms:
- Squealing, grinding, or squeaking noises when braking
- The brake pedal feels soft or spongy
- Reduced braking power or longer stopping distances
- Illuminated brake warning light on the dashboard
Causes:
- Worn-out brake pads or rotors
- Low brake fluid
- Malfunctioning ABS or brake sensors
- Leaking brake lines or master cylinder issues
How to Fix:
Regular brake inspections can help you stay ahead of any brake issues. If your brakes are making noises, feel soft, or aren’t functioning properly, it’s important to replace the pads, rotors, or fluid as necessary. For more serious brake issues, a professional mechanic should inspect the system thoroughly to identify the root cause.
