Brake warning light comes on and off while driving. Some loss of brake fluid with no apparent leaks. Suspect master cylinder leaking into vacuum booster, just as many other Altima owners are experiencing. Vehicle is out of warranty now, and I don't want to buy another master cylinder out-of-pocket from Nissan since I have read on the net where others have had replacement unit failures (such as NHTSA action number PE11020). What am I to do? Nissan should pay for a permanent repair for this obvious product defect!

Went to start vehicle and it did not start. Had to have it towed to dealership for $90. Was told it was not covered under warrenty and my car was out of warranty by 2 months. Advised to call Consumer Affairs. Waited 13 days with repeated phone calls just to be told they will not warranty the repair with no written explanation. Repair cost $757 and is only warranteed for 12,000 miles. Was told repair would take 3 days but they had my car for 21 days because the part was on back order. By the way, my car was also in for 2 recall issues: Head gasket and master brake cylindar. Pretty big issues! I was also told by service manager that if I had all my service done thru them instead of outside source they would have covered the steering lock issue. Sounds a little fishy to me. They need to recall this problem!!! or at least have a manual over ride.
