Here's what owners need to know.
No matter how much one pays for a car, recalls are always possible, and while we might not welcome the news, the recall is ultimately for the sake of safety. The National Highway Traffic Safety Administration (NHTSA) issued a recall not long ago for a total of 19 McLarens. The affected models include just one McLaren 570S, one 600LT, seven GTs, and 10 units of the 720S. All are 2020 model year examples and were manufactured between July 8, 2019 and March 15, 2020.
The problem? It turns out the brake assembly banjo bolt could be missing the holes that supply brake fluid to the caliper, thus potentially causing the brakes to fail on one of the vehicle's corners.
Banjo bolts, it should be explained, are hollow bolts used with fluid systems to control the flow through the delivery lines. In this case, these banjo bolts were delivered defective to McLaren from its supplier, though this wasn't known at the time. But wouldn't a driver notice that their combined braking power isn't working properly? Perhaps not, at least in this case.
The NHTSA further notes that affected owners enjoy the benefit of the vehicle's electronic stability control system. It's capable of detecting things such as wheel speed and will adjust the speed to other wheels in order to achieve overall braking balance.
In other words, the ESC has likely been compensating for the defective banjo bolts. This is no permanent solution, hence the recall. It doesn't appear there have been any major accidents or injuries. McLaren and the government agency say the fix is pretty simple: a certified McLaren technician needs to inspect the brakes, locate the defective bolt, and replace it with a new one. This will be done free of charge.
Oddly, McLaren has not announced when the recall will get underway but since it affects such a small number of cars, chances are these owners will be personally notified.
