2009 Nissan Altima 2. 5s was backed into in a parking lot, low speed collision, minor damage to rear bumper. A few days after this incident, when trying to start car with keyless ignition system, it took nearly 30 minutes to start. It is required that the brakes be depressed to start car, but when pushing on brakes, the brake lights do not turn on, and when ignition button is pushed it only turns on the accessories, which is the normal action expected if brake pedal was not being pressed. It is not clear if this is because of the collision or just highly coincidental. I believe that this is a problem with the brake switch. This is now an intermittent problem, but has made the car unreliable with the possibility to leave a driver stranded.
