The battery appears to be dead. After jump start, the car works for about 3 days. The vehicle will not start if left to sit over night without driving. The battery will not power the vehicle and will not allow fuel to exchange for a push start (manual 5 speed). The car was taken to beaverton Mazda dealership in beaverton oregon. They tested for electrical leaks and found none. Did not replace battery. Dealership gave battery a slow charge overnight. The battery was tested and the dealership advised battery was in like new condition. The car dies 6 days later after not being driven for 1 day. Taken back to the dealership and more tests are done, was charged for an inspection bill that says nothing is wrong. Almost 1 year later, car not driven for 1 day and battery is dead. Seems to leak electricity somewhere that cannot be found.
