Honda Pilot won’t start again. Completely dead. Possibly anti theft?

I think your battery may be weak. Have both the battery and alternator tested. Another possibility is a parasitic drain on the battery.

This just happened to me almost exactly in a 2019 Pilot!!! Once we jumped it, the anti-theft error came up. Did u ever learn anything more?

On my 2005 honda pilot, I had this same issue intermittently, one thing you might want to check is the battery terminals. Mine were showing some decent corrosion, so i cleaned them up with i think battery cleaner. This may be blocking the electric circuit from leaving the battery and turning over the engine. Havent had the issue since, been a few months. Also i had previously purchased a jump starter device that still did not get the car to start when this issue had happened, a regular jumper cables for 15 minutes seemed to work. Hope this can help some people out, and i will definitely not be purchasing a Honda again because of this issue.

I had a similar issue occur at 5:00 am while trying to head to the gym. It turned out I just had to jump start. Fortunately weather was nice and I had a battery pack to jump it. The unfortunate thing is I have to remove a plastic shroud across the grille and part of the air scoop just so I can get to the battery posts. Let her run for 15 minutes and off I went. I wonder if I left something open from the night before.

I had this problem as well, thank you for the tip, to manually unlock the door-it started up no problem. I am now considering replacing the battery.

Honda of Henderson diagnosed that my starting problem on my 2016 Honda Pilot EX-l Sensing is due to battery. After replacing the battery, same problem. Miles: 25K, 4 years old, got it brand new. This is a Class Problem, maybe the Start Button, not the starter, not the battery - the Start Button.

I have a brand new battery (about 3 months old) in my 2009 Pilot, so I know it isn’t the battery. This is the second time this happened to me, first time I was stranded. Not very happy with this. Finally brought it into the dealer and he said the battery connection is loose, common problem for this vehicle and gave me codes to re program. Today, went to head out, dead. Can’t even enter a code and wouldn’t know how to adjust battery cables so here I sit...grrrr!

The same thing keeps happening to my 2016 Pilot...just dropped it at the dealer to see if they can figure out the issue. Not the battery...it's brand new. Changed the batteries in the fobs and it's not that. I have to get out of the car and hit lock and unlock so it "senses" I'm getting in the car but on Saturday the doors wouldn't even open and I had to use the key. I'll keep everyone updated when I hear from Honda. They checked my battery last time and said it's perfect...I had to have the starter changed (recall and I was getting that "remote starter error" message) so they thought that would fix it. Nope...happening a lot more now too. Very frustrating!

Anyone solved this issue? I had a similar experience today. Parked it at a restaurant and went in to pick up may order and returned to what appeared totally dead Pilot. Tried the locks, windows and then shifting it (which was locked), nothing. I had not notived that I left the key in the ignition turned forward. Anyway, made a call to get a ride and my cables from the other car. While starting to eat my lunch, maybe 4 to 5 minutes everything turned on by itself including the windshield wipers. I cranked it and it started right up, go figure. I know it is not the battery, cables or a loose fitting which a new one was installed two weeks ago, however I did go check . I need to reset the code which I have only done only when replacing a battery in the past. It is a really strange gremlin, almost like it was waiting to power on when it wanted to.

2004 Honda Pilot i have changed two batteries that have both apparently died jumped them both off and nothing seems to work the alarm for the car stopped working have to manual open the door with the key alternator has been checked now checking the battery fuse to see if that may be the problem The stories are helpful just trying to get my only transportation running again

My 2012 honda pilot is having the same issue. After months of being told by Honda that my car is fine *and hundreds of dollars* I have found the issue. The way that Honda makes the area that the battery sits on, is slightly wonky. Certain batteries don't fit "flush" so that the cable to the post is on an angle. With vibrations driving, there is very slightly movement- enough that it loosens the connection to the negative terminal. Over time, this creates wear and your battery connection isn't tight. You can't tell, but it is. Solution for me was to use an exacta knife and slightly cut the plastic on the battery to allow the cable to sit flush and tight, reducing the meniscal movements. PRESTO! Works like a charm and haven't had an issue in months. Took to Honda and they were like OHHH that makes sense.

I'll add my tale of intrigue and woe to the mix. My wife tried starting her 2012 Pilot today, but it was as dead as a doornail; No clicks, cranks, or dash lights of any kind. The locking mechanism on her fob wouldn't even work. No dome lights or anything else had been left on the day before, and we've had absolutely no hint of a problem recently with the battery. When I tried to jumpstart it, the horn would go off as soon as I connected the last cable to the engine block. After three attempts, the horn finally stayed quiet, but even while being connected to jumper cables, the Pilot wouldn't click, crank or activate any dash lights. What's going on?

It's a parasitic drain. Most likely the radio. Pilots are notorious for this issue. I'm experiencing the same problem. Brand new battery, I haven't been driving it for a week because it's a Lemon, and found signs it was a flood vehicle. Went out to start it today and it's completely dead. No clicks, nothing!
