Dodge Nitro 2009 Problems
No car is perfect, but we've gathered everything relating to the Dodge Nitro 2009 reliability here to help you decide if it's a smart buy.
The rear left and right brake/stop lights in my 2009 Dodge Nitro are not working
If the third brake light is working, then the problem is not with the brake-pedal switch (or the third light would not work either). That the two lower brake lights stopped working together is also a clue that it's not the bulbs that are at fault.
I'd be looking at the fusebox to see if the fuse that controls the lower brake-light circuit has failed. There should be a map of the fusebox inside the plastic cover, and from that, you can identify which fuse protects that circuit, and go from there. If there's no blown fuse at fault, you need to start checking earth connections as these can also cause all sorts of electrical mayhem. An auto electrician could probably sort this quite quickly without changing any more working parts.
