Nissan Sentra is a sedan, and it is one of the oldest products of Nissan motors. The first Nissan Sentra was launched in 1982, and since then, it has been an enormous success.

One of the common problems that Nissan Sentra’s owners face is the trunk opening automatically. This problem is familiar to the owners of Nissan Sentra, but it is also common amongst the other car models. 

The trunk in modern cars uses an electronic switch to open and close the trunk.

You only have one option to replace the switch in such a case.

If the trunk’s latch is suffering from an issue, then the trunk can open automatically because the latch won’t grip the trunk lid properly. Therefore, you will also need to replace the trunk latch in such a case.
