Morgan Super 3 Common Problems & Reliability
The Morgan Super 3 is Morgan's current open three-wheeler and the successor to the 3-Wheeler, which ended production in 2021. Unveiled in February 2022 and built by hand in Malvern, it is the first Morgan with a welded aluminium unibody - there is no ash-wood frame beneath the bodywork - powered by a Ford 1.5-litre naturally aspirated three-cylinder engine with 118bhp and 110 lb-ft, mated to a Mazda-sourced five-speed manual driving the rear wheel through a bevel gear and belt. With no roof, doors or windscreen as standard, it is sold in the UK as a fair-weather weekend toy rather than daily transport, priced from around £35,000 when new. Production volumes are tiny, so examples are rare on the used market, but the Ford mechanicals are familiar to any independent garage while the Morgan bodywork and trim need specialist attention. It suits buyers who want maximum theatre and minimum pretence and are happy to dress for the weather.

Most Common Morgan Super 3 Faults & Repair Costs
Brake Pedal Feel and Linkage Interference
The Super 3's unassisted pedal box layout offers modest pedal feedback, and the linkage geometry can cause the driver's right footwear to catch on adjacent brackets when pivoting rapidly between the accelerator and brake pedal. While braking effort is adequate once firmly applied, the tight pedal spacing and spongy early travel demand acclimatisation on twisty UK B-roads and can compromise braking confidence in wet conditions.
Inconsistent or spongy brake pedal resistance on initial travel, Driver shoe or boot catching on pedal-box linkages during rapid transitions, Reduced braking confidence when pressing on along uneven UK asphalt
- Test pedal firmness and ensure progressive resistance from the first inch of travel
- Wear typical driving footwear to check whether shoes foul adjacent pedal linkages
- Verify that brake fluid has been flushed and bled without trapped air
Fly Screen Distorts the View
The Super 3's optional polycarbonate aeroscreen is designed to deflect airflow and surface spray away from the cockpit, but early batch mouldings suffered from pronounced optical distortion around the curved outer edges that warps the driver's forward perspective. The reduced screen area also provides minimal deflection at UK national speed limits, causing heavy buffeting and road spray in the cockpit without protective eye goggles.
Optical distortion or wavy line of sight through the curved edges of the fly screen, Excessive helmet or facial wind buffeting at 50–70mph on dual carriageways, Road spray and grit striking the driver's face despite fitted aeroscreen
- Sight through the fly screen from seated eye level to verify optical clarity
- Examine screen mounting brackets and screws for vibration stress cracking
- Confirm whether the revised later-specification factory aeroscreen is fitted
Pedal Box Housing Weld Defect and Master Cylinder Movement
On early-production 2023 Super 3 models, third-party manufactured pedal box housings were fabricated outside engineering drawing specifications with defective welds at the master cylinder mounting flange. Under repeated or hard emergency braking, weld fracture permits the master cylinder to deflect, breaking the hydraulic hose seal or binding the brake assembly so the pedal fails to return, creating a critical safety hazard.
Brake pedal sticking down or failing to return smoothly to resting position, Brakes binding or dragging during and after moderate brake applications, Visible deflection or movement of the master cylinder body under pedal pressure, Fluid weeping around the master cylinder hydraulic union under load
- Inspect the pedal box housing and master cylinder mounting welds for cracks or weld failure
- Check GOV.UK recall records or official dealer campaign history for safety bulletin remedy
- Depress the brake pedal hard while observing the master cylinder for structural flexing
Bespoke Avon Front Tyre Availability and Accelerated Edge Wear
The Super 3 uses bespoke 130/90R20 front tyres manufactured specifically by Avon (Speedmaster MKIII) mounted on 20-inch aerodisc wheels. The narrow vintage-inspired motorcycle footprint handles severe lateral cornering and braking forces without power steering or ABS. High-speed cornering or misaligned pull-rod steering geometry causes rapid shoulder scrubbing, and replacement tyres must be ordered through Morgan dealerships at significant expense.
Excessive scrubbing or feathered wear on front tyre tread shoulders, Front-end understeer and washed-out grip when pushing on in wet conditions, Tracking pull or wander on grooved and rutted UK road surfaces
- Measure tread depth across both 130/90R20 Avon front tyres for uneven edge wear
- Check pull-rod front suspension ball joints and tracking alignment for play
- Inspect tyre sidewalls for stress cracks or scrubbing marks against wheel rims
Rear Drive Belt Tracking Noise and Sprocket Flange Rubbing
Final drive from the Mazda five-speed manual and rear bevel box to the single rear wheel is handled by a toothed Kevlar rubber belt. If swingarm alignment, eccentric hub tensioning, or wheel reinstallation following rear tyre changes is not calibrated accurately, the belt skews sideways against the sprocket flanges. This produces noticeable transmission screeching, accelerated tooth wear, and premature belt degradation.
High-pitched screeching or chirping sound from the rear swingarm on overrun, Noticeable bevel box and final drive gear whine at sustained cruising speeds, Visible rubber dust or chafing along the outer edges of the toothed drive belt
- Inspect the final drive belt for edge fraying, stone gouges, or missing teeth
- Verify central tracking of the drive belt between both sprocket guide flanges
- Check service history for proper belt tension calibration after tyre replacement
