CLASSIC (1950–2009) — Engine options included the 2.0L Ford CVH/Zetec.
MODERN (2005–2020) — Engine options included the 2.0L Ford Duratec. We track 5 known issues on this generation, with 4 classified as significant. The most significant concern is Excessive steering roughness (£400–£800 to address).
The steering system on Morgan Plus 4 models shows abnormally high rates of roughness in operation, appearing predominantly on lower-mileage examples. This affects steering feel and precision, making the car harder to control accurately. The issue appears linked to the exposed nature of Morgan's traditional chassis design allowing contamination of steering components, particularly the steering rack and column bearings.
Rough steering reduces driving precision and can make the car difficult to control, particularly in emergency manoeuvres. Complete steering failure is unlikely but handling becomes progressively worse. Repair typically requires steering rack replacement or rebuild.
During the test drive, check the steering for excessive play, vibration or pulling to one side. Listen for groaning or whining when turning the wheel at low speed. Power steering fluid level and condition should be checked on hydraulic systems.
Morgan Plus 4 models show exceptionally high rates of suspension component wear, particularly bushes and joints, even at low mileages. The traditional chassis design with limited protection exposes suspension components to contamination and accelerated wear. This affects handling, tyre wear patterns, and MOT compliance.
Worn suspension components affect handling safety, cause accelerated tyre wear, and will result in MOT failure. Complete suspension collapse is unlikely but driving precision deteriorates significantly. Multiple components often need replacement simultaneously.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
Wheel bearings on Morgan Plus 4 models show excessive wear rates, particularly concerning given the low annual mileages typical of these sports cars. The exposed wheel assemblies and limited splash protection may contribute to contamination and accelerated bearing degradation. This is a worsening trend that affects safety.
Worn wheel bearings create safety risks including wheel detachment in extreme cases. More commonly, they cause noise, vibration, and poor handling. The bearing can seize suddenly, potentially causing loss of control. Replacement should be immediate once excessive play is detected.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
Morgan Plus 4 brake systems show high rates of binding and imbalance across axles, often appearing on low-mileage cars that may have stood unused for extended periods. The exposed brake components are subject to corrosion, and infrequent use can cause caliper pistons to seize. This creates both safety and MOT compliance issues.
Binding brakes cause accelerated pad and disc wear, reduced braking efficiency, and can lead to brake fade or fire in extreme cases. Brake imbalance makes the car dangerous under heavy braking as it will pull violently to one side. Immediate attention is required for safety.
Check brake disc condition for lipping or scoring. Test braking at moderate speed for pulling to one side or vibration through the steering wheel. Review MOT advisories for brake-related items.
Steering rack gaiters (protective rubber boots) on Morgan Plus 4 models fail at exceptionally high rates, particularly on low-mileage cars. The exposed chassis design and minimal weather protection cause rapid deterioration of rubber components. While not immediately dangerous, damaged gaiters allow contamination of the steering rack mechanism.
Damaged gaiters allow water and dirt to contaminate the steering rack, leading to accelerated internal wear and eventual rack failure. Immediate safety impact is minimal but long-term steering reliability is compromised. Gaiter replacement is straightforward if caught early.
During the test drive, check the steering for excessive play, vibration or pulling to one side. Listen for groaning or whining when turning the wheel at low speed. Power steering fluid level and condition should be checked on hydraulic systems.
