Nissan north America, inc. (Nissan) is recalling certain model year 2015 Altima and 2016 maxima vehicles manufactured October 6, 2015, to October 7, 2015. The affected vehicles have front brake calipers whose mounting bolts may not be properly tightened. I crash my car on Aug/16 and Dec/17. Both for the same reason. I lease this car on March/2016. I'm not sure that the dealer fix the problem before leased.
