The Office of Defects Investigation (ODI) opened PE11-020 to investigate possible brake performance loss due to brake fluid leaking from the master cylinder into the brake booster in the subject vehicles.A total of 237 complaints were identified by ODI and Nissan.The majority of complaints and warranty claims reported that brake malfunction indicator lamp (MIL) illumination as the only symptom of a problem.Only 12 complaints alleged any effect on brake performance and in each of these the drivers were able to stop the vehicles without incident.No crash claims could be attributed to the alleged defect. Returned part analysis data provided by Nissan showed that most of the master cylinders replaced under warranty did not have a leak condition.These replacements may have resulted from brake MIL illumination due to pad wear.For most of the warranty claims, in a few cases where a master cylinder leak was found, Nissan's testing showed that the leaks were extremely slow and would require thousands of miles or months of driving before brake performance could be affected.After an extensive study of replaced master cylinders for a presumed leak, Nissan was unable to identify any concern with the parts or design of the subject components that could affect brake performance. Nevertheless, Nissan does recognize a concern with premature brake MIL illumination and has decided to address this problem by conducting a voluntary service campaign covering approximately 1.17 million model year 2
