“Passenger and driver side floor pans, due to rust/corrosion have failed. This appears from on line resources to have been a manufacturing flaw of 2002 - 2006 altimas. A rusted through floor pan certainly affects the structural integrity of the car as well as the safety of the passengers. Road objects or passengers feet could easily puncture through what is remaining of the floor boards. Ironically, I remember having an issue similar to this on a 1979 chevette. I would have thought engineering and manufacturing process would have eliminated such a design flaw in more recent autos. …”

“Rusted floorboard- driver and front passenger. Section of floorboard has completely rusted--all that remains between driver/front passenger and street surface is auto's carpet. I strongly believe this is a safety issue. I feel that rusting of the floorboards compromises the auto's integrity, and the weakening of the auto's structure can definitely lead to an accident and result in injury to driver and others. Nissan contends they have no responsibility, since the auto is out of warranty. Such rusting which compromises the auto's integrity and safety should be indefinitely warranted. …”

“My trunk latch will randomly pop open. The first time was while driving in a residential neighborhood. The second time, I came out of a store to find my trunk open. It keeps popping open every time I drive now. It's very dangerous on the highway to suddenly have your trunk fly up blocking your view to the traffic behind you. I have jimmy rigged it with a bungee cord inside so that it only pops up about an inch or two when the latch pops. I would just duct tape it, but I need access to my daughter's stroller. I also unplugged the interior trunk light so that my battery would not be worn out. …”

“Car suddenly stops while your fmdriving at a low speed. Check engine comes on andturns vehicle off. This is very dangerous and I font understand why it hasnt been recalled. Most of the comments are said to be either the camshaft or crankshaft. They replaced the part and it was fine for 3 months and it ccontinues to do it. Im going to end up causing an accident and Nissan doesnt even care....”
