Head scratcher....
So here's he deal. 4 years in a row.
What happens, overnight, my MX fob battery dies. I replace it, and within 20 minutes, it drains the new battery dead. Replace again, same thing. This happens yearly, almost exactly 1 year, +/- 1 month.
4 years in a row now. First one I had to pay for the replacement given that my 2016 was out of warranty. Second one failed within the 1 year service warranty within 1 week of the 1 year date, so replaced at no charge. Third one failed within 1 year of the second one, about 2 weeks of the 1 year date. I thought maybe it is a Fluke, considering that #3 now lasted past the 1 year mark. But sure enough, got home this evening, went to move the MX out of the driveway so I could back the MS up and unload the trunk into the garage, and the MX not responding. Went in the house grabbed the spare key, started right up. Just checked Fob battery, 0 Volts.
Put a brand new battery in, fob unlocked the car and it started fine, went back in the house. Tried it again 15 minutes later, no response from the car. Checked battery voltage, 0 Volts. Never happens on the Model S.
Now, the first time the fob failed, I started using the spare, and within a week, the spare did the same thing. Both replaced that first time. No fob updates available, and no service warnings any of the failure times.
Didn't mind so much when I didn't need to keep paying for replacements, but any ideas? These things are expensive! No water damage, No physical damage. Even has the sticker on the bottom with the parts number and bar code from the last time it was replaced.
Ideas? The fob, also does not get hot like it would if it was shorting out. Batteries are fresh, I get them from Batteries + Bulbs with my commercial account, and voltage is good before install. Even try them in the spare fob first, leave them for a few hours or even overnight, no problem. Pop it in the failed fob, dead in 20 minutes.
