2014 ELR, 16k miles, bought used with 14k miles. Car appears to be flawless in every way.

5/24/2018, the exterior door handles wouldn't respond to touching. Pressing the unlock button on the keyfob would flash the lights, but no unlock response. Pressing the keyfob lock button chirped the horn, flashed the lights, but nothing would unlock either door. Then I noticed that each time I pressed the unlock button, the driver's window would open a small amount. Holding the button fully opened both windows, but still, no unlocking.

I reached in, grabbed the mechanical door handle, opened the door, everything seemed to reset, and no further issues the rest of the day.

Any thoughts? Will there be a code stored? CPO, dealership is willing to run a scan, which I'll do next week.

Sounds like the fob is issuing mixed signals. Maybe add new batteries to the fobs? A cheap experiment.

My thought, as well. Changed both fob batteries after the incident.
But, how could it send a strong enough signal to open the windows/flash lights, and not trigger the door locks to open? Hmm...

This morning, doors opened, ran errands, upon returning home, parking brake/placed in park/shut off engine...door open button not functional. Recylced all of the above: door switch still not functional. NOTICED the red light on the LOCK button. Pressed unlock button, door opened as normal.
Weird. I've never had to manually unlock the door after shutting off the engine. I'll check the "auto lock/unlock" settings, maybe they've changed somehow?

First open the fob and remove and replace the battery to rule out it not making good contact. I've had the same behavior with a battery that wasn't dead but needed to be moved around.

Anything else in your pocket? The ELR fob seens much more sensitive than my 2015 volt fob to interference. USB sticks and a set of keys seem to bother it. I put my key in the watch pocket of my pants, or in a cargo pocket now. Never have a problem.

Also be wary of the windows down by holding unlock. I've had it put my windows down a few times now for no reason, once in the snow/rain... and there is no way to remotely roll them back up. I had to run the heater for 2 hours and then the AC for an hour to dry out the car.

Check and see if the 12V battery terminal clamps are nice and tight.

^^^Thanks. Both fob batteries were replaced after the first incident (exterior doors not unlocking). Interior incident occurred after battery replacement.

My recent 8 year history with VW "clean diesel CRTDIs (Sportwagen, 2 Passats) makes me little nervous of electrical anomalies. I'll make certain there's nothing interfering with the fob signal.
