Thanks for the response. How to I test the 12 volt battery? It has a date of 2/17, which seems pretty new, but I am getting the 3 beeps. I have tried the trickle charge yesterday, but it does not seem to make a difference.

Please describe the three beeps. They can also be due to a charge timer being active, and trying to charge during the period it is set to not charge. Testing it is easy: let the car sit undisturbed for 15+ minutes then use a multimeter, set to DC Volts, to check the voltage between the Positive and Negative terminals. If it is below 12.2 volts then it may well be the problem.

I believe that when I stop the car and put it in park I get 3 short beeps. My daughter has been driving the car and that is how she described it. I am not charging the big battery. I was thinking it had something to do with the 12 volt battery, but maybe not. Voltage is about 12.5.

With an ICE I measure the voltage drop then the starter is engaged. So - as long as the battery can hold 12.2 volts it is healthy? Thanks.

12.5 volts is very typical for a Leaf, so likely no 12 volt battery issues. The car will occasionally charge the 12 volt battery, but in the case of pre-2015 Leafs it often doesn't charge it enough. The car tends to beep and play tinny music a LOT in the default mode. You can turn all of that off in the car's menu.

OK - thanks. Today it gave 3 short beeps when I put it in Drive, and not when I stopped and put it in Park. I have not changed any of the settings, but will take a look at those. My concern was that the beeps were a warning that would eventually leave me stranded.

AFAIK, any warning beep should be accompanied by a lit warning icon on the dash - as well as the master fault light, which lights up when any other icon does.

Just as an update, in case anyone else has this problem - it went away when I replaced one of the TPMS sensors.

One wheel had always shown a different tire pressure when viewed on LeafSpy - sometimes a few pounds off, sometimes a lot. The beeping and flashers going for two or three times started 2 months ago, then last week I started getting the yellow "low tire pressure" symbol on the dash - but it was intermittent, appearing a few miles down the road, then switching off. Throughout the whole thing I was checking tire pressures with a good gauge. When I took the TPMS sensor out, there was water in the tire. Anyway, problem solved.
