It began shortly after i purchased the car in feb 2018 with the a/c working only intermittently and the settings on the cluster having the same problem, and this electrical problem escalated into a safety issue when on dec 6 the rke failed (battery on fob strong) and a re-start on car did not work, until the spare key was tried. since dealer found no problem with either key, the safety issue remains a major concern for the senior citizen owner who might get caught again without access to the car and with a non-functioning engine. the electrical problem shows itself intermittently in unprovoked beeps of the passenger door, as well as in the cluster settings. *js
