Car engine begins to whine/whistle and when slowing to stop, a/c slows down and radio/radio lights go off. Sometimes the engine and all electrical shuts off. When turning off engine to park, there is a click-click-click that continues for a while and when doing this, the engine will not start, you cannot move the gear shift from park, and you cannot lock the car doors (electric). Eventually it will stop, and then you can start it again.
Just prior to these problems, we had the alternator and battery replaced by the local Mazda dealership. These "symptoms" started the day we picked up the car and have grown increasingly worse. We've taken the car in three separate times, for a total of 7 working days and 2 weekend days. The first time, I pulled up and turned the car off, it made the click-click noise and wouldn't start or lock. I made sure they saw what it was doing. They called a few days later and said they could not replicate the problem and didn't know what was wrong with it and to bring it back again when it is acting up, we drove it in a few days later and my husband rode with the tech to be certain they would acknowledge it. The car powered down and the radio shut off when they came to a stop. They kept it several days and still didn't know what was wrong with it. They claim the alternator "components" checked out okay. We brought it back again and left it for two more days when it started failing completely, all electrical and engine shutting down without warning. They said it failed once when a porter was driving it, but started back up and they don't know what it is. I think they put in a faulty alternator, but I'm no mechanic. What could it be? Could continuing to drive the car as we have cause more damage to it? What would you do??
