When the fob is stored near the vehicle it creates a power drain on the battery. We were camping for the weekend and the fob was generally near the vehicle (in the camper). When we left the campground at the end of the weekend, the warning indicator said not to use any auxiliary power. I am not sure how the vehicle uses the battery vs the engine or alternator to power the interior outlets, usb charging ports, and other things like the dvd/res system, but the previous power outage in the vehicle has us on high alert and we feel it is relevant as it indicates a pattern of power failure and insufficient battery or power supply to the vehicle relative to the voltage it pulls with the "bells and whistles" on the car. The warning remained for the entire 3 hour drive home.

Horn on 2018 Honda Odyssey (elite & touring trim levels) for sure. Horn is a single tone low note and is barely noticeable and woefully inadequate. Yesterday while traveling on a not very busy country road, I activated horn at about a dozen buzzards feasting on some roadkill in the roadway and had to come to an almost complete stop before they moved. They were more intimidated by presence of my vehicle than horn blaring at them. Sounds stupid, I know, but it emphasizes problem. Horn is almost entirely unnoticeable and does not get or attract attention, which makes it a definite safety concern. It does not "command" your attention and is not easily heard over ambient noises. Horn on my previous 2013 Odyssey was a dual tone horn and much louder and drew attention immediately. I seriously doubt the factory installed horn meets federal standards for decibel level. Not that it matters but it just sounds pitiful coming from an almost $50,000 fairly large vehicle. Honda has truly dropped the ball on this safety item and I believe it is enough of a concern to replace this lousy horn with a much louder dual tone horn at my own expense. Someone there should take a look at this issue. This issue comes into play at any time the horn is needed to attract attention or alert someone to any number of situations and needs to be corrected before someone gets hurt or killed.

We were driving on I75 North on sat June 10. We were right before the atlanta macon split. The vehicle completely shut down at highway speeds. The dvd player turned off. The engine turned off. The entire instrument panel went dark. There was no power to anything. The vehicle turned back on in "park" creating a horrible popping noise. The dealership (willett Honda) in morrow ga looked at the vehicle and cannot find the source of the power failure. They have been instructed to return it to us. The case number at Honda is 06075564. Jerry hogan at bommarito Honda in hazelwood mo is the sales manager and he wants us to drive the vehicle in spite of the obvious safety defect. Honda cannot detect the cause of the issue.
