I was driving from work when I heard a cranking/squealing sound coming from the rear passenger side, I stopped and checked could not find anything, but noticed that anytime I stepped on the brakes/make a turn the sound will come on, took it to a mechanic who told me it was the motor mount and also that the brakes were been affected and I could not drive more than a certain mile on the highway. Also the engine light keeps coming on my dashboard, after several repairs to whatever the problem was, it;s still on, now no one can tell if it is related to the issue car had or not, the headlights on the car hardly come on properly, even if I put them on full light, it's still looks dim and I can see with them at night when am driving, the heat suddenly comes on even without turning it on, am really scared now cause I don't want to get in an accident. Nissan needs to do something anout all this complaints especially with such high recalls .
