NHTSA Complaint #11511175 — 2017 HONDA PILOT

Went out to garage and started noticing headlights and running board lights were on, so assumed another household member had opened door to put something in the car which is not common. After this started occurring more often, asked and no one fessed up so started paying closer attention and even opening garage door just to check. After that, started noticing clicking sounds under the hood. Googling, saw online that others had similar issues. One day went to start car to head out and the car was dead. Called dealer and they said I must have left the car in accessory mode, but I wasn't so sure. AAA jumped the car with much effort. Next morning, car would not start again. This time, I remembered I had one of those jumper boxes and was able to start it, maybe because it was just one day difference. I know I was careful to make sure I fully stepped on brake to not leave it in accessory mode like dealer had said I probably did prior. Drove it around to charge the battery and went to store. When I came out, my car alarm was going off. When I got home, I left car out to see if alarm would go off and sure enough it did. I had also noticed that dashboard lights would flicker Honda symbol. This time didn't lock car and the alarm did not go off. Googled some more and luckily found on piloteers a post about replacing the control module around the driver side dash and considered myself lucky that my alarm was only going off when locked as others were saying they had to disable battery because would go off even when unlocked. Made an appt with Honda. I had a video of the car acting up in the garage and hoped that it would start in the morning. It did and showed Honda the video but of course they could not duplicate the issue but I told them I wanted the part replaced and hoped it worked b/c no way I could have unreliability continue. Said found a service bulletin with similar issue where they replaced 38320-TG7-A52 control unit so $850 later my issues are good
