- What is wrong
- McLaren Automotive Incorporated (McLaren) is recalling certain 2020 570S, GT, 2019 600LT, and 2019-2020 720S vehicles. The brake assembly banjo bolt may be missing the holes that supply brake fluid to the caliper, which would cause the brakes to fail on one corner of the vehicle.
- Risk
