Most Common McLaren 570S / 540C / 570GT Faults & Repair Costs

Moderate Risk

Paint Bubbling / Corrosion

Est. Cost£1,000–£2,500 per panel

Aluminum panels can suffer from oxidation under the paint, typically starting at the edges of the doors or wheel arches.

Warning Signs:

Small bubbles under the paint surface, Flaking paint at panel edges

Moderate Risk

Coolant Hose Clamp Leaks

Est. Cost£400–£800 (mostly labor)

McLaren used a specific type of hose clamp that can loosen over time, leading to slow coolant leaks in the engine bay.

Warning Signs:

Low coolant warning, Antifreeze smell after driving, Pink residue on undertrays

Moderate Risk

Door Latch and Soft-Close Failure

Est. Cost£500–£1,200 per door

The mechanism for the dihedral doors can become misaligned or the soft-close motor can fail, making the doors difficult to latch.

Warning Signs:

Door won't close without force, Soft-close doesn't pull the door in, Squeaking during door operation

Moderate Risk

Door Hinge Cracking and Alignment

Est. Cost£2,200–£3,000 per pair

The dihedral door hinges are under significant mechanical stress and can develop cracks over time. This affects door clearance and can damage surrounding paintwork. Hinge replacement requires careful recalibration of door alignment.

Warning Signs:

Door misalignment or uneven gaps, Cracking noise when opening doors, Paint wear on door edges from contact

High Risk

SSG Gearbox Main Shaft Bearing Wear

Est. Cost£5,000–£15,000

The 7-speed Graziano dual-clutch gearbox is generally reliable but has a known weakness in its main shaft bearings. When they collapse, gear selection becomes erratic and oil leaks can develop. A full gearbox rebuild is expensive but the issue is well understood by specialists.

Warning Signs:

Transmission fault warnings, Loss of gears or difficulty selecting gear, Whining noise from gearbox, Oil leaks from gearbox casing

Moderate Risk

Lightweight Windscreen Stress Fractures

Est. Cost£3,000–£4,500

McLaren uses thinner-than-normal glass to save weight, which makes the windscreen prone to spontaneous stress fractures. The glass can crack without any impact, typically from temperature changes or improper sealant application during a previous replacement.

Warning Signs:

Spontaneous cracks without impact, Cracks spreading from edges, Cracks appearing after temperature changes

Essential Pre-Purchase Step

Buying a used McLaren 570S / 540C / 570GT? 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.

Inspection Checklist for McLaren 570S / 540C / 570GT Buyers

Inspect the bottoms of the dihedral doors for paint bubbling or "furring" (oxidation)
Check for dampness around the radiators in the front wings; leaks are common
Verify the door soft-close and latch mechanisms operate without squeaking
Ask for a clutch "Snap" report to verify the health of the 7-speed SSG gearbox
