I HAVE PUSH BUTTON START. WHEN I PUSH THE BUTTON IT WILL CLICK AS IF THE BATTERY IS DEAD (NEW BATTERY) AND THEN NOTHING. I PUSH 7 TO 16 MORE TIMES AND THEN THE CAR STARTS. IT MAY DO THAT SEVERAL DAYS IN A ROW, SEVERAL TIMES ON ONE DAY, OR NOT FOR SEVERAL WEEKS. I TOOK IT TO MY MECHANIC (NOT NISSAN) AND THE DIAGNOSTIC TEST SHOWED NOTHING WRONG. MECHANIC THOUGHT MAYBE IT COULD BE A STARTER BEGINNING TO GO BAD BUT THERE WAS NOTHING TO POINT TO THE STARTER. HE CALLED IT A "GHOST" PROBLEM BECAUSE IT COMES AND GOES. IT SEEMS TO ME THAT THE PROBLEM IS THE IGNITION SWITCH. ONCE IT CATCHES, THE CAR RUNS JUST FINE. I BELIEVE MY ISSUE IS RELATED TO THE PRESENT NISSAN RECALL ALTHOUGH MY CAR IS NOT PART OF THE GROUP. I HAVE NOT TAKEN IT TO NISSAN YET BECAUSE IT HAS BEEN WORKING FOR TWO WEEKS. I BOUGHT THE CAR NEW IN AUGUST 2007.

MY BRAKE LIGHT ON THE CONSOLE STAYS ON FOR LONG PERIODS OF TIME AND THEN TURNS OFF. I WENT TO NISSAN AND THEY TOLD ME THAT THERE WAS A LEAK IN THE BRAKE MASTER CYLINDER AND WITH THE PART AND LABOR IT WAS ABOUT $450! MY CAR IS NO LONGER UNDER WARRANTY BUT AS I DO MY RESEARCH ONLINE I FIND THAT THIS IS HAPPENING TO OTHER NISSAN OWNERS NOT ONLY 2007 ALTIMAS. THERE IS ALREADY A RECALL FOR THE BRAKE MASTER CYLINDERS FOR SENTRAS. WHY NOT FOR ALTIMAS? IT IS CLEAR THAT THERE IS A ISSUE AND THERE IS HISTORICAL DATA TO PROVE IT. WHY DO I HAVE PAY $450 OUT OF MY POCKET WHEN IT IS A KNOW ISSUE THAT NISSAN IS AWARE OF? DO THEY WANT TO WAIT TILL THERE ARE A LOT OF ACCIDENTS BEFORE THEY DO SOMETHING ABOUT IT? PLEASE INVESTIGATE ON OUR BEHALF SO THAT NISSAN WILL REMEDY THE SITUATION AND START A RECALL. *TR

2PE11020 · Brake Master Cylinder Internal Leak
Opened May 23, 2011 · Closed Mar 14, 2012
Status: closed (inferred from source dates) · Service Brakes, Hydraulic:foundation Components:master Cylinder
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 2007 through 2012 Altima vehicles (up to June 25, 2011 production, the date of Nissan's running change for the longer life brake pad).Nissan's owner letter for the service campaign states, As your brake pads wear over time, the brake fluid level in the master cylinder reservoir will drop and may cause the brake warning lamp to illuminate.?Although this is a normal condition, there has been concern that the brake warning light illumination may be caused by a slow fluid leak over time.Nissan's service campaign will inspect the brake pads and test the master cylinder for leakage.If leakage is detected, Nissan will replace the master cylinder at no charge.If excessive pad wear is observed, customers will be notified and will be responsible for repairs.For more details concerning Nissan's service campaign, see the PE11-020 file on www.Safercar.gov. Based on the low failure rate for confirmed master cylinder leakage in the subject vehicles and the low probability that the condition would affect brake performance, this investigation is closed.
