2017 Honda Civic: battery drain or dead battery

Filed Aug 26, 2026 · Body, Electrical · CA · 1 injury

My 2017 Honda Civic just had a known BCM issue and many with the same models year from 2016-2018 experience the same failures. Honda should have a recall because it's where the car unknowingly drains the battery and the engine sits in idle/accessory mode that is damaging to other parts that the customer have to expense for.

The Body Control Module (BCM) on my 2017 Honda Civic suffered an internal failure, creating immediate safety hazards. The defect caused persistent parasitic battery drain, sudden vehicle power loss, and erratic electrical behavior. A faulty BCM can cause critical safety components—such as exterior lighting, turn signals, and windshield wipers—to fail without warning while driving. Honda has already recalled 2018–2020 Accords and 2019–2020 Insights for identical BCM programming and hardware failures (the federal safety agency Campaign 20V771000 / Honda Campaign X95). My 2017 Civic utilizes similar BCM architecture and exhibits the exact same dangerous failure symptoms. This component defect is widespread across multiple Honda platforms from this generation, and the safety recall must be expanded to include the Honda Civic before a catastrophic electrical failure results in a crash or injury. I had to replace the unit entirely out of pocket to ensure the vehicle was safe to operate.

The Body Control Module (BCM) is faulty and causes the alarm to go off on its own, lights inside the cluster glitch turning on by itself and drains the battery even with the key fob nowhere near its vicinity when off. Sometimes does not recognize the key fob.

After turning off the vehicle and locking it the vehicle continuously turns on to accessory mode on its own. On a few occasions I came out to a dead battery or have been woken up more than once to my alarm blaring in the middle of the nite and when I came out to check my vehicle it was usually turned on to accessory mode upon researching the internet I found that many owners with the 2016 and 2017 have the same problem which is a result of a faulty Body Control Module within the keyless entry system. I have taken my car to honda to be fixed it's been 3 days now with no solution on repairs yet.6/7/25

Came out to a dead battery, despite the battery being less than four months old. On one occasion, I came out to the vehicle with the windows rolled down. On another occasion, I was told there was an issue with the anti-theft system. There was even a time where I came out to my car in accessory mode, despite not turning the vehicle on. Reading online, all signs point to a failure of the BCM. This is a common enough issue where there are entire threads dedicated to the problem.

BCM module in the 2017 Civics seem to have constant Parasitic Battery Drain issues that are not being addressed by Honda. My battery died and was replaced, drain continue on a daily basis. Was able to trace to BCM module. checked online to find numerous other people having the same exact issue.

There is a short in the BCM (body control module). This causes massive parasitic drain on my battery of over an amp (roughly 1.2 amps typically). I have to pull the fuse for it (fuse 18 in the engine bay fuse box) every time I leave my car off for more than a couple hours. I'm extremely worried this short is going to cause either a fire or one of the important functional systems of my car to stop working while I'm driving. I have read MANY other reports of this happening to other 2017 Honda Civics yet Honda hasn't done anything about it.

Starting about 9 months ago I have had several occasions of electrical issues on my 2017 honda civic that is less than a year and a half old and only has 18k miles on it. It first started around the fall last year with my car repeatedly popping the trunk when I would not be near it and would come out to it in the parking lot at work and find my trunk wide open. Later on I found out the trunk popping open would force the car alarm to go off for several hours and occasionally would lead to a dead battery. When I took it in to have the issue investigated the technicians told me the couldn't diagnose the problem and that it shouldn't continue (it has continued and in fact is happening as I type this in my apartment). The next issue occurred about 2 months ago while I was driving down the interstate in the pouring rain and my windshield wipers stopped working completely. Upon having this problem inspected the technicians determined it was "faulty" windshield wiper motors and had both replaced. The latest issue that occurred was as I was driving to pensacola from washington and stopped off at a rest stop in the middle of nowhere oregon for some sleep. Upon waking up (3hrs after I shut the car off) I discovered my car was doing some glitchy thing with all the lights and dashboard where it was acting like I was turning it off and on. I had nothing turned on or plugged in when I went to sleep and when I woke up the car was completely dead and the electrical system had totally disabled the car.
