Mitsubishi Colt Common Problems & Reliability
The Mitsubishi Colt (2004–2013) is a highly practical and reliable supermini that successfully blended city car agility with a surprising amount of interior space. Sharing its underlying platform with the original Smart Forfour, it offered a levels of versatility that rivaled many small MPVs, featuring sliding rear seats and a high roofline that provided exceptional headroom. In the UK, it has established a reputation for being a "sensible" used choice, prized for its mechanical honesty, low running costs, and the charismatic performance of its turbocharged CZT and Ralliart performance variants. Reliability for the Colt is a major strong point, reflecting Mitsubishi’s focus on mechanical durability, but used buyers must investigate specific drivetrain themes. The most common technical concern involves the "Allshift" automated manual transmission, which is known for jerky low-speed shifts and potential failures of the electronic actuator; the traditional manual gearbox is significantly more robust. Mechanically, the naturally aspirated 1.1-litre and 1.3-litre petrol engines are durable and utilize timing chains, though high-mileage examples should be checked for cooling system leaks from the radiator’s plastic end-tanks. Additionally, early models were subject to recalls regarding the electronic power steering (EPS) connector pins. When buying a used Colt in the UK, the focus should be on maintenance history and verifying that all interior electronics operate correctly. Prospective owners should carefully test the central locking and electric windows multiple times, as the actuators and regulators are common minor failure points. It is also vital to check the radiator for any signs of "pink" coolant residue and to ensure the air conditioning blows ice-cold. For the best ownership experience, a post-2009 facelift model with the 1.3-litre petrol engine and manual gearbox is highly recommended, offering the ultimate combination of performance, economy, and legendary Mitsubishi reliability.

Most Common Mitsubishi Colt Faults & Repair Costs
Allshift Semi-Auto Actuator Failure
The electronic clutch actuator in semi-automatic models can fail, leaving the car stuck in gear.
Car won't start (won't find neutral), Stuck in gear, Jerky gear changes
- Check for smooth engagement of all gears
- Ask if the actuator has been replaced or refurbished
Timing Chain Stretch
The 1.1 and 1.3 petrol engines use timing chains that can stretch if oil changes are neglected.
Rattling noise on cold start, Engine management light (timing codes), Poor running
- Listen carefully to the engine from cold
- Check service history for frequent oil changes
Front Suspension Wear
Anti-roll bar links and ball joints wear prematurely, leading to knocking noises.
Knocking noise over speed bumps, Vague steering feel
- Listen for clunks during the test drive
- Inspect bushes and links for play
Buying a used Mitsubishi Colt? Always check for hidden finance and write-off history.
Mechanical problems are only half the battle. Over 1 in 3 UK used cars checked have unpaid finance or accident write-off records that could cause you to lose the car or thousands in value.
