2018 Nissan Armada

Component or system unknown other than personal research. Suspect break sensor or possibly called stop lamp. Again, not positive. My Armada randomly will not start, leaving me stranded many times (with children). When I push the start button, sometimes the car shakes while making a horrible sound and trying to start but never starts. It has to be jumped off before it will start. Sometimes, it just clicks and does nothing. We took to our local Midas, who found no codes triggered, battery, alternator, starter etc all good. We drove another week and it happened again so this time we took to the Nissan dealership. Again, they checked everything, found nothing. Upon researching myself, I'm finding many people having this same issue yet Nissan team has no clue what to fix. I'm stuck driving a car that leaves me randomly stranded or doesn't start at all for me to even leave my house. I tried looking up the part myself and adding a new one (desperate to find the issue) but I'm not car savvy and can not locate the "easy" piece near my break pedal. I'm getting desperate and should not have a car with less than 70,000 miles leaving me stranded. No warning lights appear.

My Nissan Armada is 4 years old with 42,000 miles and has needed two brake switches replaced on it to date. This is RIDICULOUS! This car is completely unsafe. It has failed to start more times than I can count, and it most recently broke down on my on New Years Day. I had to have it towed. I have reported this issue to Nissan and they have done nothing to help make this right! I am now starting a FaceBook group (of other Nissan Armada owners that are experiencing the same issue) to file complaints against Nissan for this. This is a serious safety issue and needs to be resolved.
