Independent 765LT and 765LT Spider specialists at Thorney Motorsport Toronto. Rear-window recall remediation, intake resonator tab service, turbo inlet baffle upgrades, A/C compressor work — every documented 765LT item handled at a fraction of dealer pricing.
McLaren's 2020–2022 Super Series Longtail — 765 coupes and 765 Spiders, all M840T. Lighter than 720S, 755 hp, full aero kit, distinct exhaust note. The car that defined what the Super Series could be at its sharpest.
The 765LT has two live NHTSA recalls (rear window detachment on 2021 coupes, brake-line routing on selected VINs), plus the platform's shared items: intake resonator tab failures, the famous turbo inlet baffle issue, A/C compressor service, hydraulic accumulators. Every one of them has a documented fix.

Faults, Symptoms & Repair Options
The 765LT shares some 720S service concerns but has a distinct coupe rear-window campaign. The Spider and factory-roof-scoop coupe exclusions matter; a generic recall list can otherwise mislead owners.

McLaren documents possible separation of the polycarbonate rear window from its support. [1]
Confirm campaign 24V-901 completion before track use. Have McLaren verify the VIN and any interim restrictions applicable to the car.
765LT Graziano seven-speed SSG
Thorney documents bearing and seal failures producing leakage at gearbox tell-tale openings. [2] [3]
Identify the fluid and inspect the leak before planning a seal or internal repair. Keep the drain opening unobstructed and bring any previous gearbox invoices.

McLaren issued a campaign to correct clutch-cooler hose contact. [4]
Review campaign completion and inspect any fluid residue in the affected area. Ask for a leak-source diagnosis before treating the symptom as internal gearbox failure.
765LT Proactive Chassis Control II
Thorney’s rebuild service addresses damper seals, damaged internals and associated spring components. [5]
For a harsh ride or suspension warning, check hydraulic pressure, accumulator condition and damper leakage. The system needs a measured diagnosis before a replacement list is chosen.

Document brake measurements, tyre condition and impact marks. Assess the actual use history and installed components rather than quoting a fixed lifespan for every car.
A documented fault is not a prediction for every car. These checks depend on the VIN, engine, equipment and service history. Recall references may describe US-market vehicles; confirm Canadian applicability and completion with the manufacturer. Recall remedies are arranged through its authorized network.
Start with the model year, VIN, symptoms and previous invoices. We discuss the inspection needed to identify the cause, then explain the findings and proposed work. A warning message or a fault listed above does not, by itself, establish which part needs replacement.
Sources checked 7 September 2026. Bulletin and campaign applicability must be confirmed for the individual vehicle.

Buying a McLaren 765LT without an independent PPI from a specialist is buying problems you can’t see. The list below is what we work through on every 765LT that comes through the shop for a PPI.
Critical. Pull VIN against the recall — if outstanding, only the dealer can fit the updated fastener kit. Test for rattle from the rear cabin during the test drive.
Pull VIN. If outstanding, route to dealer before purchase.
Visual inspection any time the intake is opened. Broken tabs are an immediate failure mode — lean codes, hissing, rough idle.
Pull airbox covers, inspect both inlet pipes for baffle integrity. Confirm updated McLaren part or aftermarket silicone fitted.
Vent thermometer for ten-plus minutes at idle in heat. A working compressor at test-drive can fail before delivery — know what you’re inheriting.
Overnight sit, photograph all four corners cold, watch the rise. PCC II accumulators are wear items.
Demand ECU logs, alignment-shim history, brake pad and rotor records. 765LTs are tracked.
Front inspection panel first, then front wings, rear wings, engine cover. Bubbling = panel replacement.
Door cards under bass, tweeter response, rear-screen edge stability, door pulls. Most addressable in shop.
Toronto-area PPIs by appointment. Enclosed transport coordinated where required.
This is the published Thorney Motorsport McLaren service schedule, used worldwide by every TMS International dealer including Thorney Motorsport Toronto. Each yearly service builds on the core oil-and-filter — the heavier years add brake fluid, cabin filter, air filters; year 5 adds coolant; year 10 is the big one. After year 10 the schedule starts again.

* On the 6th year "charcoal fuel filter" item: McLaren recommends replacement of the charcoal fuel filter on Sports Series models (540C, 570S, 570GT, 600LT, 620R) at the 6th-year service, which requires removing the fuel tank. The 765LT is Super Series and is not affected by this. Sports Series owners can see our position on this item on the respective Sports Series model pages.
Schedule above is published by Thorney Motorsport UK — see the McLaren Service Schedule on their site for the source. Every TMS International dealer, including Thorney Motorsport Toronto, follows this schedule. Subtle differences exist for the 765LT, 675LT, 600LT and GT but are minor and not worth listing separately. The Senna, P1 and F1 are not covered by this schedule.
Modern McLarens have a reputation for intimidating service bills that keeps some prospective owners away from one of the great driving cars of our era. The honest truth is that the platform is well-understood. The known issues have known fixes. A specialist who actually knows the cars can keep one running properly for materially less than the reputation implies — and that’s exactly what we’re here for.
Every item on the common-issues list above has a fix we’ve done many times over. Known parts, known procedures, fair labour. Owning a 765LT does not have to mean a six-figure parts catalogue.
We run McLaren-grade diagnostic software, OE service procedures, and genuine McLaren parts where they matter. The savings come from operating as a focused independent specialist — not from cutting corners on the work itself. Same quality outcome at a price that makes regular service realistic instead of dreaded.
Thorney Motorsport in the UK has been the world’s leading independent McLaren house for fifteen-plus years. Their workshop articles on accumulator failure, bodywork corrosion, and DCT seal repair are the reference for the entire independent McLaren community worldwide. Toronto operates as the Canadian arm.
You see the bill before we touch the car. Parts source identified (OE, OE-equivalent, or Thorney-developed). No surprise invoices, no "we’ll see how long it takes" labour. Predictable cost is half the affordability story.
Canadian consumer law protects your right to service your McLaren at a qualified independent shop without affecting factory warranty, provided the work meets manufacturer specification and is documented. We keep a complete dealer-standard digital service record for every car that passes through.
The 765LT is a thrilling car. It deserves to be driven. We’re here to make sure cost-of-ownership concerns never become the reason yours sits in the garage. Annual service, the occasional repair, a PPI before your next McLaren — that’s the whole picture, and it’s a manageable one.
Each model has its own page covering platform-specific common issues, PPI red flags, and the service schedule we follow. Return to the Thorney Motorsport Toronto McLaren hub for the full picture, or jump directly to a specific car.
Most of our McLaren customers drive in from the GTA. For southwestern Ontario McLaren owners, we are the closest Thorney-grade independent specialist.
Enclosed flatbed transport for out-of-province owners arranged on request. Roadside-assistance services that aren’t exotic-trained should never load a McLaren.
Whether it’s annual service, a stubborn fault you can’t get to the bottom of, a PPI before you commit, or a full performance build — give us a call. Walk-in welcome by appointment.
