The McLaren 720S Spider, introduced in 2018, stands out as one of the most celebrated supercars of the modern era. With its lightweight carbon fiber Monocage II chassis, retractable hardtop, and aggressive 4.0-liter twin-turbo V8 producing a blistering 710 horsepower, the 720S Spider combines top-tier performance with the thrill of open-top driving. However, like many high-performance cars, the 720S Spider has its own set of quirks and issues. Here’s a meticulous look at the common problems you may encounter with a McLaren 720S Spider, along with essential information for potential buyers and current owners.
1. Mechanical and Engine Issues
The McLaren 720S Spider is a testament to automotive engineering, but it’s not without its mechanical flaws. Here are some of the engine and mechanical issues commonly reported by owners:
Turbocharger Issues
The twin-turbo V8, while a powerful powerhouse, has seen a range of complaints regarding turbo lag and turbocharger reliability. Turbos can occasionally experience failure due to the high stress and temperatures under which they operate. Turbocharger replacements or repairs are costly, typically due to the specialized labor required and the quality of materials McLaren uses.
Signs to Watch For:
- Decrease in power or throttle responsiveness.
- Increased exhaust smoke or unusual sounds, like whining or whooshing, from the engine bay.
Overheating and Cooling System Failures
The cooling system of the McLaren 720S Spider has also been noted as a potential weak point. Given the high-output nature of the engine, keeping it cool is critical, especially during spirited driving or track use. Cooling system issues can stem from faulty thermostats, radiator leaks, or coolant hose weaknesses.
Signs to Watch For:
- Increased engine temperature gauge reading.
- Coolant leaks beneath the car.
- Frequent refilling of coolant levels.
Transmission Problems
Owners have reported occasional issues with the 7-speed dual-clutch transmission, particularly with hard shifting or delays in response. While McLaren’s dual-clutch system is one of the fastest on the market, issues may arise after extended use, especially if the car has been driven hard or frequently taken to the track.
Signs to Watch For:
- Jerky or rough gear changes, especially when downshifting.
- Delays or lag when accelerating from a standstill.
2. Electronic and Software Issues
Electronics play a huge role in the 720S Spider, from the advanced infotainment system to the driver display. Here are some common electronic issues that may affect this model:
Infotainment System Glitches
The infotainment system on the 720S Spider can sometimes suffer from software bugs and slow responses. Owners report occasional freezing or lag in the display, and some have noted that the navigation system and Bluetooth functions can be inconsistent.
Signs to Watch For:
- Delays when interacting with the touchscreen.
- Freezing or crashing of the infotainment system.
- Issues connecting to Bluetooth or audio disruptions.
Digital Instrument Cluster Problems
The 720S Spider’s digital instrument cluster is another point of occasional failure. Owners have reported issues with the display flickering, lagging, or sometimes not turning on at all. Given the amount of data the cluster displays—speed, RPM, and various performance metrics—any issues here can be both inconvenient and hazardous.
Signs to Watch For:
- Flickering or dimming of the display.
- Failure to display important information.
- Lagging in updating information like speed or RPM.
3. Body and Convertible Roof Issues
The retractable hardtop is a defining feature of the 720S Spider, but it’s also a component that has its own set of challenges. Here’s what to look out for:
Convertible Roof Malfunctions
Convertible roofs, especially those in high-performance cars, are typically more complex and prone to issues. For the McLaren 720S Spider, the retractable hardtop can suffer from hydraulic or motor malfunctions, which may prevent it from opening or closing correctly. Replacing or repairing the roof’s motorized components can be expensive due to the specialized parts and labor involved.
Signs to Watch For:
- Difficulty in opening or closing the roof.
- Strange noises, such as grinding, when operating the roof.
- Roof alignment issues, leading to leaks.
Body Panel Misalignment
The 720S Spider’s bodywork is incredibly precise, with tight tolerances and lightweight materials. Some owners report misalignment or gaps between body panels, which could be due to manufacturing tolerances or wear over time. This is often a cosmetic issue, but it can impact aerodynamics and sometimes lead to vibrations or noises at high speeds.
Signs to Watch For:
- Visible gaps or misalignment between panels.
- Unusual noises when driving at high speeds.
- Panels feeling loose or unsecured.
4. Interior Wear and Quality Control Issues
Inside the 720S Spider, McLaren uses premium materials and a minimalist layout. However, some elements of the interior have shown early signs of wear and tear, as well as quality control inconsistencies.
Premature Wear on Seats and Dashboard
Owners have noted that the Alcantara and leather surfaces in the 720S Spider can wear faster than expected, especially on frequently touched areas like seats and steering wheels. This issue is common in high-performance cars due to the focus on lightweight materials, but it’s still something potential buyers should be aware of.
Signs to Watch For:
- Visible wear, scratches, or peeling on leather and Alcantara surfaces.
- Fading or discoloration on the dashboard and console.
Loose Interior Trim and Rattles
Rattles and vibrations are another issue reported by some 720S Spider owners, often stemming from loose trim pieces or the minimal padding used for weight savings. While these aren’t structural problems, they can detract from the otherwise premium feel of the car’s interior.
Signs to Watch For:
- Rattling sounds during driving, particularly on rough roads.
- Loose or misaligned interior trim pieces.
5. Expensive Ownership Costs: Maintenance and Repairs
The McLaren 720S Spider is undeniably costly to maintain, largely due to the specialized nature of the parts and the precision required in repairs. Here’s a breakdown of what ownership costs might entail:
Regular Maintenance: Routine servicing costs for the 720S Spider can range from $1,500 to $2,500 annually, depending on usage and the specific work done. Major services, which include more in-depth inspections and component replacements, can run upwards of $5,000.
Repair Costs: For specific repairs—especially those related to the turbo, transmission, or convertible roof—the costs can easily reach $10,000 or more. Turbocharger replacements, for example, may cost around $15,000, while transmission repairs could range from $8,000 to $12,000, depending on the extent of the issue.
Extended Warranty Options: To mitigate the high cost of repairs, some McLaren owners opt for extended warranties, though these can cost between $5,000 and $8,000 annually depending on coverage.
What to Look for When Buying a Used McLaren 720S Spider
For potential buyers considering a pre-owned 720S Spider, here are a few crucial tips:
- Service History: Ensure the vehicle has a complete service history with authorized McLaren dealers or certified workshops. Regular servicing is key to longevity, especially with high-performance cars.
- Turbo and Transmission Checks: Ask for records of any previous turbo or transmission work, as these are known weak points and could be costly to address down the road.
- Roof Functionality: Test the retractable roof multiple times to ensure smooth operation and check for any unusual noises.
- Exterior and Interior Inspection: Look closely at body panels for alignment and inspect the interior for any signs of premature wear or loose trim.
Final Thoughts: Is the McLaren 720S Spider Worth the Ownership Cost?
The McLaren 720S Spider is undeniably a thrilling supercar with a level of performance and style few vehicles can match. However, with high performance comes high maintenance costs and a greater likelihood of mechanical and electronic issues. For those who are willing to shoulder the expense and dedicate themselves to proper upkeep, the 720S Spider offers a driving experience that is truly unmatched. But for buyers on the fence, it’s essential to understand that this car’s beauty and performance come with potential downsides in the form of pricey repairs and occasional frustrations.
In summary, the McLaren 720S Spider is a high-maintenance marvel, a blend of beauty and brute power that, while not perfect, remains one of the most exhilarating cars on the road today. For enthusiasts ready to commit, few cars can compete with the adrenaline-pumping experience this car provides.
