I went through one opener first and then the second responding to remotes only if they were really close to the opener and had nearly new batteries. Range kept getting worse until opener would only work from wall button. The power supply on the main board was gradually failing and the first impact is range of the receiver (and increased sensitivity to interference). A few months after repairing the first opener, the second one failed the same way. I installed the openers on both doors in 2000. The manufacturer claims the new circuit boards are improved and they are working well so far. My openers are Craftsman, but Liftmaster, Chamberlain, and Craftsman are all manufactured by Chamberlain.
I have talked to several others who had the same issue. The receiver has a really high gain amplifier to receive the very low power signals from the remotes. That amplifier is sensitive to low voltage so reduced receiving range is the first symptom. I kept my old circuit cards, but have not yet tried to repair the power supplies.
FWIW, I have had no issues with my openers and the Homelink mirror after having the 3G upgrade done in January. I open and close the smaller door at least twice every day. Also, when the opener first started to fail it would work if I took the lights out so I thought it was interference from the LED bulbs which I used to minimize heat when leaving the lights on. It worked for a while with CFL or incandescent bulbs, but not long.
Well, I am not sure on the opener being the problem - but it certainly is possible.
The remote works just fine with the car off, and our other car Homelink mirror works from pretty far down the street. More testing may be in order.
If anything the remote transmitter radio could be the failing component - it might be more sensitive to noise now. I would bet that there is plenty of RF noise produced by the LEAF...and it may have changed slightly with the 3G radio???
On the LED Front - we don't have CFL or LED's in the opener now - just a good old incandescent high vibration bulb. When we had the problem with LED's it wouldn't affect opening the door from the street as the LED's wouldn't be on - we just couldn't close to door after driving out of the garage with the LED's on. This was happening with any of our cars and even our remote keypad.
