A recently discovered issue with the antilock brake system (ABS) of Nissan's 2015 Murano crossover has prompted a recall of more than 10,000 cars. The issue lies with the car's solenoid valves, which may be contaminated.
According to the official recall press release, if the valves are contaminated, hydraulic brake pressure would either rapidly built up or drop off completely. This would lead to an overall unstable vehicle more prone to losing control and causing accidents.
The recall orders owners of Muranos built between December 4, 2014 and March 17, 2015 to take their cars to local dealers for an on site brake inspection, and, in the event of contaminated actuators, a replacement. Nissan is providing ABS replacements to compromised vehicles free of charge.
Antilock brake systems work by using a network of speed sensors, a hydraulic control unit, and a small, computerized control module to monitor the state of state of a vehicles wheels. If an imminent wheel lock is detected, the system applies hydraulic pressure to stabilize the wheel and provide better control of the vehicle.
When using antilock brakes, it's important to remember not to panic pump the brakes in the event of a freeze up. Instead, firmly apply pressure to the brake and let the system do its work. Some drivers are also under the misconception that ABS improve the stopping distance of cars. This is not the case, and the same safe driving principles should be applied when driving an ABS-enhanced vehicle.
As of the time of this writing, no injuries or accidents have been caused by the issue.
