2007 LOTUS ELISE

Typical onset: 40,000-80,000 mi, especially on track-driven cars

Symptoms: Sudden loss of oil pressure during hard cornering or track use, Metallic knocking or ticking from lower end, Catastrophic engine failure with spun bearings or damaged pistons, Oil light flickers during sustained lateral G-loads

Fix: Factory oil pan baffling is inadequate for high-G cornering. Fix requires either oil pan modification/accusump install ($800-1,200) or full engine rebuild if damage occurred (25-35 hours labor). Short block replacement or used engine swap if spun bearings. Track cars absolutely need baffled pan or dry sump.

Estimated cost: $6,000-12,000

Typical onset: 60,000-100,000 mi

Symptoms: Transmission fluid dripping near front of engine bay, Burnt transmission fluid smell after spirited driving, Delayed or harsh shifts when gearbox runs hot, Puddle of ATF under car after sitting

Fix: Crimped fittings on factory cooler lines corrode and crack. Lines run under clam, so removal required for proper access (4-6 hours with clam off). Replace with braided stainless lines and add larger aftermarket cooler while you're in there. OEM lines alone are band-aid fix.

Estimated cost: $800-1,500

Symptoms: Gelcoat cracks near headlight openings or hood shut lines, Stress cracks at clam mounting points, Paint chipping or delamination on front clamshell, Cracks propagating from stone chips

Fix: Fiberglass clams are stone-chip magnets and crack easily. Proper repair requires clam removal, backing with fiberglass mat, gelcoat work, and respray (12-18 hours bodywork). Most owners live with small cracks or DIY patch. Full clam respray runs $2,500-4,000 at quality shop. Front clam removal alone is 3-4 hours.

Estimated cost: $1,200-4,000

Typical onset: 50,000-90,000 mi

Symptoms: Temp gauge climbing in traffic or slow-speed driving, Coolant overflow tank bubbling or pressurizing, Heat soak after shutting down engine, Coolant loss with no visible leaks

Fix: System is cramped and hard to bleed properly. Common culprits: failed radiator ($400 part, 4-5 hours with clam removal), clogged header tank, or persistent airlock after any coolant service. Bleeding requires specific procedure with car at angles. Aftermarket header tank upgrade ($300) helps. Track cars need oil cooler and upgraded radiator.

Estimated cost: $800-1,800

Typical onset: 40,000-80,000 mi

Symptoms: Sloppy or notchy shift feel, Difficulty engaging 2nd or 3rd gear when cold, Excessive side-to-side play in shifter, Grinding into reverse

Fix: Cable bushings wear and linkage gets sloppy. Most owners do bushings as maintenance item (2-3 hours, $150-250 in parts). Cables themselves rarely fail but can stretch. Aftermarket brass bushing kits are upgrade over OEM plastic. DIY-friendly job if you're flexible enough to work in the footwell.

Estimated cost: $300-600

Typical onset: 50,000-90,000 mi

Symptoms: Clunking on throttle lift or hard acceleration, Excessive engine movement visible from cockpit, Vibration through shifter or pedals, Drivetrain lash on gear changes

Fix: Rear transmission mount fails first due to leverage and heat. Replace all three mounts as a set (4-5 hours labor). Polyurethane aftermarket mounts add NVH but sharpen throttle response. OEM rubber mounts last 60-80k typically. Requires lifting engine slightly, not terrible job but tight quarters.

Estimated cost: $600-1,000
