McLaren 675LT Common Problems & Reliability
A track-focused, limited-run variant of the 650S. Widely regarded by owners as one of the more reliable McLarens, with well-documented accumulator wear as the main recurring maintenance item.
Frequently asked questions
Is the 675LT considered reliable overall?
Yes, relative to other McLarens — owner discussions frequently describe it as one of the most reliable models in the range, with many owners reporting no significant issues even at higher mileage.
What issues actually come up on a 675LT?
The most cited mechanical item is accumulator wear, generally needing replacement roughly every 4–5 years as part of normal ownership. Occasional Vee-module oil seepage and isolated reports of wheel bearing or thermostat failure also appear in owner threads, alongside electrical gremlins like AC recalibrating itself or intermittent misfire codes.
Are there bodywork or trim issues to check for?
Paint blistering under paint-protection film on the aluminium body panels comes up across most McLarens from this era, not just the 675LT, so it's worth inspecting regardless of model. A handful of owners have also reported rear wheel-arch wear from rear-steer/tyre contact, though this isn't described as a widespread defect.
