McLaren 570GT Service.
The grand-touring Sport Series, properly looked after.

Independent 570GT specialists at Thorney Motorsport Toronto. Glass tailgate seals, cabin heat soak, headliner sag, plus all standard Sports Series items — handled to OE spec at a fraction of the dealer's bill.
570GT · M838T · Sports Series (GT variant)
The 570GT softened the Sports Series — and made it a properly liveable everyday McLaren.
McLaren's grand-tourer take on the 570S — fixed glass hatch, real luggage space behind the seats, softer chassis tune, more leather, less hard-edged. A genuinely usable McLaren for owners who want one car. Mechanically the 570GT shares almost everything with the 570S; the differences are in the cabin, the tailgate, and the ride.
The 570GT inherits the Sports Series fault list (hinges, panels, IRIS) and adds a small number of GT-specific items — glass tailgate seal water ingress, summer cabin heat soak through the panoramic glass, and a headliner that occasionally sags from heat exposure. None of it should put you off a GT; all of it should be checked before purchase.
What We See
570GT common issues. Documented, not guessed.
The McLaren 570GT is a great driver’s car — and like every modern McLaren, it has a handful of items worth knowing about. The list below blends what owners have documented in the McLarenLife community, what Thorney Motorsport UK has written up in their workshop articles, and what we see at the shop. None of it should put you off the car. These are simply the items every current and prospective 570GT owner should keep an eye on.
01
Glass hatch and roof cabin heat soak
The huge fixed rear glass and panoramic roof cause significant cabin heat soak in southern Ontario summers. Owners describe a goldfish-bowl feel; the IRIS screen can wash out in direct sun. 2018+ cars shipped with slightly darker tints for some markets. Ceramic film is a known retrofit.
- Not a defect — design constraint, but real ownership pain
- Ceramic film retrofit is a $500–$1,200 fix that materially improves the cabin
- Electrochromic option, if fitted, should be confirmed working
02
Glass tailgate seal water ingress
Owners report water entering around the glass tailgate when the seal isn’t correctly adjusted. McLaren dealer adjustment usually resolves; in stubborn cases a new seal kit is needed.
- Water-test on every PPI — garden hose, methodical
- Tailgate misalignment is the most common root cause
- Inexpensive to fix when caught early
03
Headliner / roof lining sag
Sag near the rear glass area, almost certainly heat-related. Roof lining is GT-specific. Replacement is straightforward but the panel itself is GT-only.
- Inspect the headliner rear corners and along the rear glass edge
- Heat film + new lining is a long-term fix
- GT-specific part — plan around lead time
04
Cracking aluminum door hinges
Shared with 540C/570S/600LT. Inspect both hinges for hairline cracks at the upper casting web. Later-production GT cars got the stronger hinge.
- Inspection is non-negotiable on every PPI
- Stronger hinge fitted on later production
- Replacement is McLaren-only
05
Aluminum body panel corrosion
Sports Series construction: doors and wings are aluminum, with the same edge-bubble corrosion mode as 540C/570S/600LT. Eligible for cosmetic warranty when in date.
- Front wing edges first
- Cosmetic warranty claim should be made before it expires
- Out-of-warranty: panel replacement only
06
IRIS infotainment freezing / boot-loop
Same Sports Series head unit. Boot loops, ghost touches, climate dropouts. Cold-boot test is essential.
- Cold-boot test on every PPI
- Confirm latest software
- Hard failure replacement is expensive
07
Door window switch water ingress
Sports Series shared issue. Test every switch, replace as needed, run window relearn.
- Window relearn procedure after switch replacement
- Replacement switches inexpensive when caught early
- Cars left outside are higher-risk
Pre-Purchase Inspection
The 570GT PPI checklist we’d want done on our own car.
Buying a McLaren 570GT without an independent PPI from a specialist is buying problems you can’t see. The list below is what we work through on every 570GT that comes through the shop for a PPI.
Glass tailgate water test
Hose the seal area for 60 seconds, then check the luggage compartment carpet, glass alignment, and seal seat. Repeat with the tailgate cycled. This is the single biggest GT-specific PPI item.
Cabin heat soak inspection
Inspect headliner around the rear glass for sag or yellowing. Confirm electrochromic option (if fitted) cycles cleanly between tints. Note whether ceramic film is installed.
Headliner sag check
Run fingers along the rear-glass-side headliner edge. Sag is GT-specific and heat-related.
Door hinge inspection
Same as 570S — lift each door under bright light, inspect casting webbing.
IRIS cold boot
Power down fully, boot from cold. Confirm clean startup, working DAB or Bluetooth.
Aluminum panel edges
Doors, front/rear wings, engine cover. Look for paint bubbling at panel edges.
Door window switches
Test every switch inside and out. Frameless glass relearn may be needed.
Underbody for scrape damage
The GT is slightly less low than 570S, but still scrape-prone. Confirm front lift if optioned.
Service history and recall checks
McLaren or qualified independent only. Banjo-bolt recall (NHTSA) check by VIN. Confirm coolant service with mandatory clamp replacement.

Service Schedule
570GT service schedule. Straight from Thorney.
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.
| Service | Parts Required | Notes |
|---|---|---|
| 1st | Oil Filter, Oil, Consumables | — |
| 2nd | Oil Filter, Oil, Brake Fluid, Cabin Filter, Air Filters, Consumables | — |
| 3rd | Oil Filter, Oil, Consumables | — |
| 4th | Oil Filter, Oil, Brake Fluid, Cabin Filter, Air Filters, Consumables | — |
| 5th | Oil Filter, Oil, Coolant, Consumables | Coolant year |
| 6th | Oil Filter, Oil, Brake Fluid, Cabin Filter, Air Filters, Consumables | Charcoal fuel filter if required * |
| 7th | Oil Filter, Oil, Consumables | — |
| 8th | Oil Filter, Oil, Brake Fluid, Cabin Filter, Air Filters, Consumables | — |
| 9th | Oil Filter, Oil, Consumables | — |
| 10th | Oil Filter, Oil, Brake Fluid, Cabin Filter, Air Filters, Coolant, Consumables | The big one |
| …then the schedule restarts from year 1. | ||
Kilometre-triggered items
Layered into whichever annual service the car hits when the km trigger comes due.
| Kilometres | Parts Required | Notes |
|---|---|---|
| 32,000 km | Clutch Oil + Filter | DCT health |
| 64,000 km | Clutch Oil, Gearbox Oil, Filters | Major DCT |
| 96,000 km | Spark Plugs | Labour varies by model |
* On the 6th year "charcoal fuel filter" item: McLaren recommends replacement of the charcoal fuel filter on Sports Series models at the 6th-year service, which requires removing the fuel tank — a labour-intensive job. The 570GT is Sports Series and is therefore on this recommendation. Thorney’s position — and ours — is that McLaren’s 6-year recommendation is excessive. The filter supplier’s own recommendation is 100,000–160,000 km. We only replace if there’s a fuel smell after brimming the tank or starting issues after a fill-up. An informed owner is the best owner.
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.
Affordable McLaren Ownership
Own the car. Lose the anxiety.
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.
i
Real solutions for the known faults
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 570GT does not have to mean a six-figure parts catalogue.
ii
OE-grade work at independent rates
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.
iii
Thorney UK platform depth
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.
iv
Quoted before we start. Every time.
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.
v
Factory warranty stays intact
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.
vi
The car you bought for the reason you bought it
The 570GT 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.
