2017 Honda Civic Electrical System Problems

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.

I am filing a safety complaint regarding my 2017 Honda Civic Hatchback and the dangerous issue related to its air conditioning (A/C) system — a problem affecting many Civic owners nationwide. I initially brought my vehicle to Honda City Chicago for a Honda “campaign” repair (a term they use instead of calling it a recall) in 2023 and again this year, related to the A/C system. I was told the issue would be resolved. However, after agreeing to an optional transmission oil change they recommended, I was later told the A/C still wasn’t fixed — and that I now needed to pay $400 for a diagnostic. That diagnostic revealed the actual problem: a locked A/C compressor. (Which they knew they just wanted the money) This defect is not just an inconvenience — it’s a serious safety hazard. When the A/C is turned on, the locked compressor causes the engine to shake violently and stall completely. This happened to me at a red light; the car shut off, became unresponsive, and I was stuck blocking traffic. If this had occurred while driving at higher speeds, the consequences could have been catastrophic. Many Civic owners have reported similar compressor failures leading to engine stalls and unsafe driving conditions. Honda is aware of this issue but continues to treat it as isolated rather than a systemic defect. I urge the NHTSA to open a formal investigation into this widespread and dangerous issue involving locked A/C compressors in 2016–2020 Honda Civics. A safety recall is warranted before more drivers are put at risk or harmed due to this known defect.

While driving my Honda civic 2017, a loud static noise suddenly started coming from the vehicle’s audio system or speakers. The noise is persistent and does not stop unless I turn off the vehicle completely. This creates a significant distraction and could interfere with hearing emergency vehicles or other road sounds. This issue occurs randomly and is a serious safety concern.

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

I drove home from work today like normal. Pushed the engine start/stop button before getting out of the car. The radio was still on, and the dash was still on, with Accessory Mode, push "start/stop" twice to turn off, or something similar to that. I pushed the button twice. It went to accessory mode. I started the engine, drove the car out of the drive way, came back, pushed the button to turn off the car... accessory mode. turned the car on, turned the car off.... accessory mode. Moved the keys all away from the car. Started the car (which i could do because it WAS STILL IN ACCESSORY MODE) and drove the car, meanwhile there was a big warning saying there was no key fob in the proximity. Parked the car, pushed the on/off button.... accessory mode. I have tried everything I can think of, the car wont lock. It wont exit accessory mode unless its in full on start. Someone could come along and steal my car because I cant turn it off. all i can do is disconnect the battery and after 2-3 days i connect it and it works just temporarily. This is not ok and unsafe especially when i have a new born and stranded in the middle of the wors place due to this issue.

The abs speed sensor on honda vehicles are placed in such a way that is breaks often. And when it breaks, it leads to multiple sensors going off which may cause the abs to lock up while braking normally, car accelerating unexpectedly.For me the speed sensor on the right wheel was broken. This lead the car to accelerate unexpectedly and then the sensors would go off. Car accelerating and braking in a weird way would definitely lead to some issues. And when you go to the dealership for this issue, first they won't be able to diagnose it. They will simple reset the codes and say uts an intermittent failure and charge you 100 dollars for nothing. Then you have to go again the other day with the same issue and then they tell you its speed sensor. I think that's a bad service and since honda knows of this beong common issue with how they have placed the sensor it should be recalled.

About a week ago my car began going into accessory mode on its own leaving my interior and exterior lights, my dash board lights and my head unit on until i noticed so my car couldve been dead if i wouldnt have seen. also since the car is locked and it goes into accessory mode on its own the alarm starts going off due to the security system thinking its being broken into. ive done my research trying to figure out what the issue is and ive found a huge amount of other people are also dealing with this issue. during my research i found that the cause for the car going into accessory mode and the alarms going off is the body control module. so many people are saying they filed complaints and tried to get a hold of honda to try and get a recall started but nothing has come of it and im hoping that you guys can change that. i looked into the body control module and you cant even get the part right now due to very high demand and the part being on back order indefinitely due to so many people dealing with this issue. i hope something can come of this thank you.

My vehicles Body Control Module has malfunctioned and now I have to get a new one. When driving my car will begin to flash all of the warning lights including the power steering, break system, TMPS system and the immobilizer light. This is distracting while driving and it makes me feel like I am going to crash and I could injure myself or others on the road when these lights are distracting and I am not in a safe place to pull over. Honda Marysville has inspected the vehicle and has confirmed that the Body Control Module has failed. A bunch of alerts began to pop up and I was unsure of which ones to fix. I checked all my tires and they were within normal range so I was confused why my car was showing me the warning light. There were no other warnings that were shown. My car alarm would go off and the lights on the dash would flash when I turned my car off.

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.

The air conditioning stopped working for the second time. So far the compressor bearing has been replaced as well as the condenser.

Body control module/ECU had to be reset at dealership and possible replacement in near future. Glitch occurred and cut power to hazards, turn signals, lights, door locks, etc. during operation of vehicle.

car alarm going off for an extended period of time caused a short at the battery and caused a fire that destroyed the vehicle.

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.

Car fuel injectors will fail and cause misfiring. Dangerous to drive due to engine running rough. Unusual for fuel injectors to go out so soon especially when driven with care and using correct fuel octane.

2nd attempt. I went to download pictures and was kicked out of site. 2017 Honda Civic EX Sedan bought used 2021. So far I've needed 2 new batteries in a very short amount of time. Multiple warning lights are appearing when I start car. Charging System Problem, Power Steering System (EPS) Problem, Charging System Problem, Hill Start Assist Problem, Vehicle Stability Assist (VSA) Problem, Brake Hold System Problem. Yes, charging System Problem was showing twice. Available for inspection. Yes, my safety is at risk, I'm afraid and paranoid on what else could happen while I'm driving. I'm afraid to drive my car for my own safety. You know Honda, my Life matters too! I've went online and read others with similar problems from used to brand new, going into Limp mode not being able to drive over 40 mph and myself being severely inconvenienced with my JOB. Dealership appt this Tuesday. Occurances: Nov 13 12:32 pm 12.19 TWICE 12.21 Once 12.26.23 9:39am AND 11:23am AND 1:10pm 1.2.24 10:21 am 1.4.24 11:42 am AND 12:34 pm 1.5.24 11:13 am 1.6.24 11:37 am brake light came on, binging, then went away. 1.6.24 12:12pm. This is happening almost everyday now. Thank you!!

Keep getting LANE KEEPING and ADAPTIVE CRUISE CONTROL errors randomly as well as BRAKE SYSTEM warning lights. Took to Honda and they said my camera and radar were functioning fine and recalibrated to be sure. I’m still receiving error messages daily.

BCM Failed causing an electrical start problem and the car will not completely turn off. With BCM failed doors will not unlock with the remote and the car fails to start or starts and fails to turn off. This is a known problem with these cars that honda will not address and a safety concern for my family as the car has turned itself off while in motion.

My apologies, I just filled out a form (Your Complaint Number: 11563943) and forgot to add problems with AC with my 2017 Honda Civic EX Sedan. My AC went out, went to local dealership, they recharged this around August 2023 I believe. Good now, but my point is I'd ask how long this will last. They said they don't know. I'm like a day, week, month(s)? Again they couldn't say. I live in a very warm area during the Summer, need AC and I need a cool AC environment when driving. I think I deserve to be comfortable. At the dealership, I had mentioned about a Honda recall letter I received about AC. It was either the Compressor or Condenser that is recalled, I forget. Well, they stated after looking at my car, that it was the item that isn't covered. Bill would be close to $1,000.00, I believe. Come on. I find this shady, confusing and concerning with Honda. Thank you again for your help!!! Yes my Life is at risk with this as well. Again, my Life matters also! This is my 4th Honda and I never had so many things go sideways with the last three Hondas as I'm experiencing now with this 2017 Civic EX. This is just ridiculous. Just about fed up with Honda.

Car was draining battery because it would turn on randomly. They replaced the ignition switch, which didn’t work, then the alarm would go off constantly so I took it back to dealership. They said the part is backordered and they have NO idea how long it will be. It has been nearly 2 months, and I NEED my car for work and my 3 kids. I understand this is a well known issue, and the 2018-2019 models were recalled. Dealer says the have several similar issues with the 2017 models. I got a Honda for reliability, but instead I have had the worst car issues of any I have driven.

Car has a faulty board control module. Car randomly starts itself in accessory mode, even when key fob is not present or batteries are removed. Other times, car will click and not turn on, or show random error messages. Car will intermittently not start; shows “keyless start system problem.” Car alarm randomly goes off. Car will intermittently not turn off once started. Internet search reveals multiple other individuals with the same problem, sometimes covered under warranty and other times not. Honda of America is sometimes helpful and other times, not. Problems are intermittent and difficult to reproduce, necessitating additional diagnostics by dealers. Among other problems reported are problems with door locks, windshield wipers, and headlights. I have concerns that the electrical problems will lead to serious safety issues, such as: lights turning on or off while driving; inability to turn off ignition in an emergency; wipers not working during rain (wet conditions seem to correlate to more problems, for other drivers and for me, suggesting an issue with corrosion), or getting locked into/out of the vehicle in an emergency.
