 After only 70,000 miles my transmission has to be replaced on my 2013 altima. The car begin to shake unexpectedly one day and shut down. I've never had any mechanical issues with my car since I purchased it at 30,000 miles and I've always had the recommended maintenance done, so replacing the transmission was a shock! Be prepared to pay over 3K to repair, depending on what dealership fixes it.I would definitely recommend purchasing a extended warranty if you decide to purchase a Nissan . The cvt transmission has the worst reviews I've ever seen online . Calling corporate is like talking to no-one . They won't do anything !!!!! I'm definitely trading my car for a HONDA .
