The Mitsubishi Colt has been a popular compact car choice for UK drivers, but like any vehicle, it comes with its share of common issues. Understanding these potential problems can help owners identify issues early and maintain their vehicle properly. From electrical gremlins to transmission concerns, we’ll explore the most frequent Mitsubishi Colt problems reported by owners and mechanics across the UK.
Electrical system failures
One of the most persistent issues with the Mitsubishi Colt involves electrical system malfunctions. Many owners report problems with the central locking system, which can fail intermittently or stop working entirely. The central locking actuators are particularly prone to failure, especially in older models.
Window mechanism problems are equally common, with electric window motors failing prematurely. The front passenger window is often the first to show signs of trouble, moving slowly or getting stuck halfway. Power steering failures have also been reported, particularly in models equipped with electric power steering systems.
Dashboard warning lights may illuminate without apparent cause, often pointing to faulty sensors or wiring issues. The ABS warning light is particularly troublesome, sometimes indicating problems with wheel speed sensors rather than actual brake system faults.
Transmission and clutch problems
Manual transmission issues plague many Mitsubishi Colt models, especially those with higher mileage. Gear selection can become notchy and difficult, particularly when shifting into second gear. The clutch mechanism tends to wear prematurely, with many owners reporting clutch judder and slipping around the 60,000-mile mark.
CVT (Continuously Variable Transmission) models present their own set of challenges. The transmission fluid requires frequent changes, and failure to maintain proper service intervals can result in complete transmission failure. CVT models may exhibit jerky acceleration or unusual whining noises during operation.
According to our AutopartsPro mechanics, many Colt transmission problems stem from inadequate maintenance rather than inherent design flaws. Regular gearbox oil changes can significantly extend transmission life.
Always check the clutch pedal feel during test drives – a spongy or high bite point often indicates impending clutch replacement requirements.
Engine cooling system issues
Overheating problems are relatively common in Mitsubishi Colts, particularly in models with the 1.5-litre engine. The radiator tends to develop leaks around the plastic end tanks, leading to coolant loss and potential engine damage. Thermostat failures are also frequent, causing erratic temperature readings and poor cabin heating.
Water pump failures typically occur between 80,000-100,000 miles, often accompanied by coolant leaks from the weep hole. The expansion tank cap frequently fails to maintain proper pressure, leading to coolant loss and air pockets in the system.
Cooling fans may fail to operate correctly, particularly the auxiliary fan used during air conditioning operation. This can result in overheating during traffic jams or hot weather conditions. Our technicians recommend regular coolant system maintenance to prevent these costly repairs.
Suspension and steering concerns
Front suspension components wear prematurely on many Colt models, with ball joints and anti-roll bar links being particular weak points. Clunking noises from the front suspension during low-speed manoeuvres often indicate worn suspension bushings or drop links.
Steering rack problems manifest as heavy steering or wandering at motorway speeds. The power steering pump may develop leaks, leading to whining noises and eventual steering assistance loss. Wheel bearings also tend to fail earlier than expected, particularly on the front wheels.
Shock absorber wear is accelerated by the UK’s pothole-riddled roads, with many owners reporting a bouncy ride quality after 50,000 miles. Regular inspection of shock absorbers is essential for maintaining vehicle safety and comfort.
Warning Signs Your Car Has a Problem
Recognising early warning signs can prevent minor issues from becoming major repairs. Here are the key symptoms to watch for:
- Dashboard warning lights remaining illuminated
- Unusual noises from transmission during gear changes
- Coolant temperature gauge reading higher than normal
- Electric windows moving slowly or intermittently
- Steering becoming heavy or unresponsive
How to fix the problems
| Problem | Typical Repair | Estimated Cost | Labour Time |
|---|---|---|---|
| Central locking failure | Replace door actuators | £150-300 | 2-3 hours |
| Clutch replacement | Full clutch kit installation | £600-900 | 4-6 hours |
| Radiator leak | New radiator fitting | £200-350 | 2-3 hours |
| Water pump failure | Water pump and belt replacement | £300-450 | 3-4 hours |
| Front suspension noise | Ball joint/drop link replacement | £100-250 | 1-2 hours |
Many Colt problems can be prevented with regular maintenance – don’t skip service intervals, as this often leads to expensive repairs later.
DIY enthusiasts can tackle some repairs themselves. Simple tasks like air filter replacement and basic maintenance can be completed at home with minimal tools.
| Maintenance Task | Frequency | DIY Difficulty | Cost Saving |
|---|---|---|---|
| Engine oil change | Every 10,000 miles | Easy | £30-50 |
| Air filter replacement | Every 20,000 miles | Easy | £15-25 |
| Spark plug change | Every 40,000 miles | Moderate | £40-80 |
| Brake pad replacement | Every 30,000 miles | Difficult | £100-200 |
When to See a Mechanic
Certain symptoms require immediate professional attention to prevent safety hazards or expensive damage. Contact a qualified technician immediately if you experience complete steering loss, brake pedal fade, or coolant temperature warnings.
Transmission problems should be diagnosed promptly, as continued driving with faulty transmission components can cause catastrophic damage. Unusual engine noises, particularly knocking or grinding sounds, warrant immediate investigation.
Electrical issues affecting safety systems like ABS or airbags require professional diagnosis using specialised equipment. Many modern Colt models require dealer-level diagnostic tools for proper fault identification.
- Any brake-related warning lights or symptoms
- Complete electrical system failures
- Engine overheating or coolant loss
- Transmission slipping or harsh shifting
- Unusual vibrations or handling characteristics
Frequently Asked Questions (FAQ)
What is the most common problem with Mitsubishi Colt?
Electrical system failures, particularly central locking and window mechanisms, are the most frequently reported issues by UK owners.
How reliable is the Mitsubishi Colt engine?
The engines are generally reliable when properly maintained, with most problems relating to cooling system components rather than internal engine wear.
When should I replace the Colt’s clutch?
Most Colt clutches require replacement between 60,000-80,000 miles, depending on driving style and maintenance history.
Are Mitsubishi Colt parts expensive?
Parts are reasonably priced compared to premium brands, with many components available from independent suppliers at competitive prices.
Is the CVT transmission reliable in Colt models?
CVT reliability depends heavily on maintenance; regular fluid changes every 40,000 miles significantly improve longevity and performance.
Final Recommendation
The Mitsubishi Colt remains a practical choice for UK drivers when potential issues are understood and addressed proactively. Regular maintenance is crucial for preventing the most common problems, particularly electrical and cooling system failures.
