Common Problems with the Lotus Exige S (2012-2021)
1. Clutch and Transmission Wear
Given the Exige S’s performance-oriented design, the clutch is under significant strain, especially when driven aggressively. Track days and spirited driving can accelerate clutch wear, leading to slippage, difficulty in shifting, or complete clutch failure. The manual transmission is generally reliable but can suffer from gear engagement issues and synchro wear, especially if the car has been driven hard without sufficient maintenance.
Signs and Prevention: When test-driving an Exige S, pay close attention to clutch engagement. Any signs of slippage, unusual sounds when shifting, or stiffness in the transmission could indicate wear. Regular clutch checks and fluid changes, especially after track days, are essential to extending the clutch’s life. Clutch replacement on the Exige S can be costly due to labor-intensive work, so verifying its condition is crucial.
2. Engine Mount Durability
The supercharged 3.5-liter V6 engine in the Exige S puts significant strain on the engine mounts, which are responsible for securing the engine and absorbing vibrations. Over time, aggressive driving or frequent track use can lead to engine mount wear or failure. This issue manifests as excessive vibration, knocking noises from the engine bay, or a noticeable shift in engine position.
Signs and Prevention: Signs of failing engine mounts include increased vibrations during acceleration and idle, as well as knocking sounds when shifting gears or turning at low speeds. Preventative measures include regular inspections and ensuring mounts are checked during routine service intervals. Replacing worn engine mounts promptly can prevent further drivetrain damage.
3. Supercharger Heat Management and Cooling System Issues
The Exige S’s supercharged V6 is known for producing considerable heat, especially under intense driving conditions. This heat buildup can strain the cooling system, which includes radiators, coolant hoses, and fans. Overheating issues may arise if the cooling system isn’t meticulously maintained. Owners who regularly track their Exige S often upgrade cooling components to prevent overheating.
Signs and Prevention: Watch for warning lights, coolant leaks, or unusually high engine temperatures, which are indicators of cooling system issues. Aftermarket upgrades to the cooling system, such as improved radiators or additional fans, can help maintain optimal temperatures during heavy use. Frequent coolant checks and flushes can also help avoid issues related to coolant degradation or contamination.
4. Electronics and Dashboard Malfunctions
While the Exige S maintains a relatively spartan interior, some owners report issues with electronic components, particularly the dashboard display and infotainment. Over time, electrical faults may emerge, ranging from sensor malfunctions to intermittent failure of dash lighting and display elements. Moisture intrusion, particularly in humid climates, can exacerbate these issues.
Signs and Prevention: Inspect the dashboard and electronic components for any flickering, unresponsive buttons, or warning lights that don’t clear. Electronics can be affected by moisture and age, so keeping the cabin dry and minimizing direct exposure to elements is key. Checking for any aftermarket electronics can also help as improper installations can lead to wiring issues.
5. Suspension and Bushing Wear
The Exige S is designed for precision handling, meaning its suspension components are finely tuned for performance rather than longevity. High-mileage vehicles or those driven frequently on rough surfaces may exhibit wear in suspension bushings, ball joints, and shock absorbers. Bushing wear can affect handling precision, while worn shocks may lead to a rougher ride and diminished cornering performance.
Signs and Prevention: Take the car on a test drive, ideally on a variety of road surfaces, to check for any knocking sounds, uneven tire wear, or excessive body roll, which may indicate worn suspension parts. For owners planning frequent track use, upgrading to performance bushings and shocks can improve durability and handling performance.
6. Corrosion in Exposed Areas
Although the Exige S’s lightweight body components include corrosion-resistant materials, certain areas, like the exhaust and undercarriage, are still vulnerable to rust. This issue is particularly common in regions with wet climates or where road salt is heavily used. Corrosion can affect exhaust components and, in some cases, compromise structural integrity if not addressed.
Signs and Prevention: Inspect the undercarriage and exhaust system carefully for signs of rust, particularly around welds and joints. Regular washing, especially in winter, can help prevent salt buildup and slow the spread of corrosion. Applying rust protection or anti-corrosion coatings is a preventive measure that can extend the vehicle’s lifespan.
7. Brake Pad and Rotor Wear
Given the Exige S’s high-performance nature, the brakes are frequently subjected to heavy use, especially if the car is driven on a track. The standard brake pads and rotors are effective for street use but may wear quickly under high-stress conditions. Brake pad wear often leads to diminished stopping power, while rotor wear can cause vibration or pulsing when braking.
Signs and Prevention: When test-driving, check for any squeaking, grinding, or pulsation when braking, as these could indicate pad or rotor wear. For frequent track users, upgrading to performance pads and rotors is advisable. Regular inspection and replacement are key to maintaining braking effectiveness.
Buying Tips: What to Look for in a 2012-2021 Lotus Exige S
Check the Clutch and Transmission: As one of the most vulnerable components, the clutch should be thoroughly checked. Ask for the service history to see if any clutch or transmission work has been done, as replacement is costly.
Verify Cooling System Condition: Ensure that the coolant system has been regularly maintained, especially if the car has been used on the track. Ask if any upgrades have been made, as aftermarket cooling components can be beneficial for long-term reliability.
Inspect Suspension and Bushings: Test the vehicle’s handling, checking for unusual sounds or a loose feeling. Suspension wear can be costly, so ensure the vehicle’s components are in good condition or recently replaced.
Look for Evidence of Track Use: Many Exige S models are track-driven, which can accelerate wear on components. Signs of track use include roll cage or harness mounts, excessive wear on tires, and aftermarket upgrades.
Check for Recalls: Verify if any recalls have been performed on the vehicle, particularly for engine and electronics issues. A dealer should be able to provide this information if uncertain.
