A common, and often frustrating, issue for McLaren owners is the susceptibility of their windshields and roof glass to cracking. Due to the vehicle's extremely rigid carbon fibre chassis and the large, thinly designed glass panels, any stress from the chassis flexing, a minor stone chip, or extreme temperature changes can cause a crack to appear, often starting from the edge and spreading.
This issue is particularly prevalent on the 720S, which features a large, bubble-like glass canopy, and the 570S, due to the design of its front fascia and glass curvature.
A visible crack that appears to originate from the edge of the glass, without an obvious impact point.
Spiderweb-like cracks from a stone chip that spread quickly.
A sudden cracking sound when the car is stationary or in motion.
In the case of roof glass, a crack may form over the driver's head.
Chassis Rigidity: While a rigid chassis is great for performance, it means less flex is absorbed by the body and more is transferred to the glass panels.
Thermal Stress: Extreme temperature changes, such as going from a very hot day to a cold night, can cause the glass to expand and contract unevenly, leading to stress fractures.
Stone Chips: The large, low-angle windshields are highly susceptible to being hit by road debris and rocks, which can easily cause a chip that propagates into a crack.
Improper Installation: If a new windshield is not installed perfectly, it can create uneven pressure points that lead to cracking.
A cracked windshield can weaken the structural integrity of the vehicle in a crash and can obstruct the driver's view.
Replacing the specialised glass is extremely expensive.
The recurring nature of this issue is a source of frequent complaints from owners.
For small chips, a resin injection can be used to prevent the crack from spreading, but this is often a temporary fix.
A full replacement of the glass is required for a stress crack or a crack that is in the driver's line of sight.
The replacement must be done by a certified McLaren technician to ensure proper fitment and to prevent future issues.
Some dealerships may cover the repair under warranty if it is a confirmed stress crack and not caused by an impact.
Minor Chip Repair: AED 500 - 1,500
Windshield Replacement: AED 15,000 - 30,000+
Roof Glass Replacement: Varies, but can be a similar price to the windshield.

If you get a chip, get it repaired immediately before it has a chance to spread.
While McLaren is known for its exquisite design, some owners have reported issues with the quality of the factory paint and trim. The most significant problem is paint blistering or bubbling, which can be caused by a manufacturing defect.
The primer does not properly adhere to the aluminium or composite panels. Other common issues include loose interior trim pieces and minor exterior trim damage.
This issue is primarily noted on the 570S, 600LT, and the 720S, especially in the earlier model years.
Small bubbles or blisters appear in the paint, often at the edges of body panels.
The paint flaking or peeling away from the surface.
Interior trim pieces, such as those on the dashboard or door panels, become loose or rattling.
Uneven paint texture or orange peel in certain areas.
Manufacturing Defects: The primary cause of paint bubbling is an issue during the painting process itself, where moisture or contaminants are trapped between the primer and the metal or composite panel.
Chassis Flex: The ultra-rigid carbon fibre chassis can transfer stress to the body panels, which may lead to paint cracking or bubbling over time.
Harsh Climate: Extreme heat and humidity in regions like the UAE can accelerate the degradation of materials and cause paint to blister.
Poor Prep Work: A lack of proper surface preparation before painting can cause the paint to fail prematurely.
These issues detract from the vehicle's stunning appearance and can lower its resale value.
It can be frustrating to see these flaws on a high-end, expensive vehicle.
If an owner attempts a repair outside of an authorised dealer, it may void the paint warranty.
For paint blistering, a full panel repainting is often required. The flawed paint must be stripped down to the bare material before being re-primed and re-painted to ensure a lasting fix.
Loose interior trim pieces should be resecured or replaced by a professional.
Minor issues may be covered under the manufacturer's warranty, but owners should check the terms, as McLaren has changed its policy on paintwork "corrosion" issues in the past.
Paint Repair (per panel): AED 10,000 - 30,000+
Interior Trim Repair: AED 500 - 2,500+
Consider a full-body Paint Protection Film (PPF) wrap to protect the paint from physical damage and UV rays.

The issue has been linked to a design flaw and is a common complaint among owners, as it can compromise the door's function and the overall structural integrity of the car.
This problem is widely reported on the Sports Series, including the 540C, 570S, and 570GT.
A visible crack on the hinge itself, often near a weld point or a bolt hole.
A loud creaking or clicking noise when opening or closing the door.
The door may feel loose or exhibit excessive play when fully opened.
The door's alignment may be affected, causing it to catch on other body panels.
Design Flaw: The hinges, particularly on the Sports Series, were not engineered to handle the long-term stress of the large, heavy doors, leading to premature failure.
Chassis Flex: Despite the stiff carbon fibre tub, the movement and vibrations transferred through the chassis can put additional stress on the hinge's weak points.
Physical Damage: Slamming the doors or forcing them open or closed can exacerbate the problem.
While not an immediate safety hazard in a crash, a completely failed hinge could cause a door to detach, presenting a serious risk.
A cracked hinge detracts from the car's aesthetic value and makes a simple act like opening the door feel concerning.
The repair requires specialised parts and labour, making it a costly fix.
A diagnostic check of the door hinges is performed by a professional to confirm the presence of a crack.
The entire hinge assembly is replaced with a new, and sometimes updated, part.
McLaren has occasionally offered goodwill gestures to out-of-warranty cars with this issue, but it is not guaranteed.
Door Hinge Replacement (per side): AED 7,500 - 10,000
Labour: AED 1,500 - 3,000+
Do not force the doors open or closed.
Get the creaking or unusual noises from the hinges fixed immediately.
Avoid leaving the doors fully open for extended periods, as this can put unnecessary stress on the hinges.
