Altima seems reliable, not really.
Since purchasing this car it has been in the shop at least 4 maybe 5 times (pretty bad that it is so many times that I can no longer keep count). The first three times, it was in the shop were within in month period. The transmission kept failing, and the car wouldn't start. The first time it started failing, I was driving on the highway and was unable to pick up speed. Was pretty sure I was going to die. Nissan's engineers looked at it and failed to fix it two times because the problem kept happening. I guess the third time's the charm. But they were happy to take our money each time just the same. One of the times, I was driving the car to the dealership to get the problem addressed and it stalled out while I was taking a left turn. I nearly got killed because a car was coming. The transmission, slow to pick up, picked up at the last second. Since then, the car has seemed fine aside from the minor annoyances, such as the Bluetooth randomly not working, the screen going wonky, the speakers sounding bad, and the tire pressure being all over the place. Nissan gave us a car with paper-thin brake pads (we totally could have died), a small hole in one of the tires, and a shitty transmission. Now, the car jerks back and forth when accelerating and decelerating (but only from time to time). Nissan was happy to drive it around, waste our gas, say nothing was wrong, and take another $250 for doing nothing. 2013 Nissan Altima are lemons. Do not buy one. It costs more in fixes than the car is worth.
