2015 Honda Accord Electrical System

Having a huge amount of probable parasitic drain. Can’t figure out where it’s coming from but killing a brand new battery in weeks

In 2017, my vehicle was part of a Honda recall for the battery sensor. I had the recall service completed at Colerain Honda in Cincinnati, OH. Honda marked recall repair as completed in 2017, but the same defect has been ongoing since 2021 through today. I have had to replace multiple alternators and batteries, believing the recall repair (battery sensor issue) was properly resolved, but the issue persists. This raises concern that the recall work was either not done correctly or not done at all. The dealership has refused to provide records or assistance, leaving me to cover repair costs throughout the years. This is a safety and reliability concern that remains unresolved. When I contacted the dealership, they were unable or unwilling to provide documentation of the actual recall repair outside of "it's been completed, we can't see back that far", leaving me uncertain whether the work was properly performed and how they did it. I was also treated rudely and dismissed when requesting answers or proof. This raises a potential safety risk: If the recall repair was never done, my vehicle is still at risk of electrical fire or failure. If the repair was improperly performed, it could leave me and other drivers in danger. I am requesting NHTSA investigate whether Honda and Colerain Honda fulfilled their recall obligations in this case.

Odometer Fraud. The contact purchased a 2015 Honda Accord. The contact stated that while attempting to register the vehicle, it was discovered that there was a mileage discrepancy. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 60,300 and at the time of registration, it was discovered that the mileage was 242,000.

I am filing a complaint regarding an unresolved and hazardous safety issue tied to a federally mandated recall on my 2015 Honda Accord (Recall #KH0 – Battery Management Sensor). The recall was eventually performed, but only after inappropriate pushback from the dealer due to my vehicle having a salvage title — which is irrelevant under federal recall law. The core issue is that this sensor regulates the electrical system and can cause overcharging or undercharging — which in my case, led to premature alternator failure. Honda’s own Technical Service Bulletin (TSB 17-069) acknowledges the link between BMS failure and electrical system damage. Furthermore, Honda’s own documentation acknowledges that many customers — particularly used car or private party buyers — were never properly notified of the Battery Management Sensor (BMS) recall. As a result, these customers may be unjustly denied warranty or reimbursement claims, through no fault of their own. This applies directly to my case. I had already replaced the alternator out of pocket due to failure, long before I was ever informed of the recall. Once I became aware of the issue and brought the car in, I was relieved that Honda performed the BMS recall repair, which resolved the dashboard alerts. However, it is unfair and unacceptable that Honda refuses to cover the damage the faulty system caused prior to the recall being completed — especially when I was never properly notified in the first place. This places the financial burden of a known safety defect onto the customer, despite the existence of a federally mandated recall directly linked to the damage.

The contact owns a 2015 Honda Accord. The contact stated that while driving at an undisclosed speed, several unknown warning lights were illuminated, and the vehicle lost motive power. The contact stated the failure occurred while driving on a steep hill. The contact stated that a passerby stopped and assisted with getting the vehicle to the shoulder of the roadway. The passerby connected battery cables to start the vehicle. The vehicle started and the contact drove the vehicle to a nearby Auto Parts store. The representative charged the battery overnight; however, the next day the failure reoccurred. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The contact stated that an elderly church member replaced the battery sensor; however, the failure reoccurred. The manufacturer was not made aware of the failure. The failure mileage was approximately 109,000.

The Flow Honda in Winston Salem service advisor told me that this model and year of the Accord Hybrid have this problem.

Car first started showing issues with the charge system. The car would randomly not start and would require a jump start. I replaced the battery and the car worked fine for 2 weeks and then it just wouldn't start at all. A new alternator was put in and the care drove fine for 1 month. Took it back to dealer mechanic and he said he needed a new alternator. Got the alternator replace and care worked fine 2 months and then it was back to not starting or it wouldn't accelerate pass 20 mph and the power steering light would come on and the steering wheel would lock up. The tire traction light came on as well as the check engine and battery light ABS and emergency brake light. Took it to the mechanic he replaced the terminal post and components after the car would start at all even with a jump start. The car worked fine for 3 months and then it started cutting off in the middle of traffic on the road while driving it and would not cut back on. Took to the dealer and was told that it was a camshaft sensor. The camshaft sensors was replaced and the car started cutting off while driving it on the road and the steering wheel would lock up. All lights on the dashboard would come on including the power steering wheel, tire traction, check engine, emergency brake, battery light, ABS light. Radio would cut off and reset continuously while driving and make static pops. The car will continue to cut off while driving and cut back on at times or just not restart.

The car is having starter issues. At times I can push the button and it will start right up. Then sometimes it takes several clicks. This a safety concern especially in a dangerous situation. There have been several complaints about this and Honda had yet to do anything. Hopefully someone addresses this soon!

When starting the car via push button start , there is a clicking sound. The battery was replaced fuses checked and sometimes it will start on the first push other times it takes 5 minutes. I had to start my car after I had to leave my car suddenly due to needing to enter a store asap to retrieve my wallet. Upon returning, one person clearly was attempting to enter my car who saw me than left. So I had to leave the area quickly. But the car just clicked when ignition button pushed. 6 mins later I was able to start it. The car only has 36000 miles on it. But I’ve had every thing checked, alternator, battery etc. the starter is the the obvious problem

After having my Honda Accord sport 2015 4 cylinder, I started to notice around 90k miles an occasional grinding noise when starting the car that is getting progressively worse. I've had previous Hondas with many more miles and never had this issue before. I believe the issue is the starter, but I have not been able to take it to the mechanic yet. I intend to go this weekend. I'd like to also state there have been numerous reports regarding starters for a V6 engine, and I believe it is the same for 4 cylinders.

My car will randomly say check charge system. I have got my battery and alternator both tested and they're both at Perfect working capacity I Google the problem and I found out there has been a recall in the past on the same issue with 2013 to 2016 models. And my car is having the same electrical issue my car runs and drive fine it does not turn off or anything but it just keeps on showing check charge system. The past recalls has been in the Rusted salt belt area and that is where I am in Massachusetts. It is the battery connector issue. Is the sensor that connects to the battery I guess that has been faulty in the past and other cars and has been in multiple 9th gen Honda Accords. And my car keeps having the same issue even though my battery and alternator are perfect. How do I get Honda to fix this.

The vehicle has had several incidents where it won't start when the ignition button is pushed. The dashboard lights come on, but they run through and say that all the ADAS systems are inoperable. This has o cured numerous times I per the years and still hasnt been fixed.

Car intermiittantly does not start Has happened at least four times this month(Jan 2023). Had battery and alternator checked they are fine.. Sometimes will start on second try. Car only has 44,400 miles on it. Have read hundreds of complaints for the same issue. It is time for a recall on a defective part.

Like many others, I have had starter problems on my 2015 Honda Accord. It has less than 50,000 miles and is kept in a garage. The starter should not need to be replaced so soon and I believe it is defective.

Back up camera black screen, safety issue.

Starter is inconsistent. Looked online and many customers have complained about it. It’s not just a starter it’s a flaw in the design. Looks like other parts need to be replaced in order to correct the issue. This should be a recall.

Possible starter/electrical issue when trying to start vehicle. Will start up with no problems at time and then others it will only click and display all dash lights. At times it will take only a few attempts and then it will start while other times it takes several minutes to start. This has been an issue leaving you stranded in a excessively hot vehicle oftentimes with small children in car seats in the back with no air. Dealers say this is a common issue with this make and model although no recall has been put in place. This issue first began in 2020 and has been intermittent since then.

Intermittent starting of car. Push button start works inconsistently. All lights on dashboard light up and system sometimes makes clicking sound. Have been stranded numerous times. I often times have young grandchildren in car so this is a safety issue.

Vehicle failing to start consistently. Battery is fine. No noise is heard when moving key to start. Either starter or ignition is bad. Concern about being stranded.

6/24/2022 I was driving my 2015 Honda Accord with 65k miles when the car had no power, unable to accelerate, and limited steering. The following warning lights went on : Malfunction Indicator Lamp, Vehicle Stability System Indicator, Electric Power Steering System Indicstor, and Low Tire Pressure indicator (new tires last week). I let the car sit for awhile and restarted it with the same warnings showing. Very scary and unsafe to suddenly lose power and steering. I had just returned from a trip on a mountain road and busy highway which could have had deadly results. My car is a 2015 with 65 thousand miles on it- how does something this dangerous occur?

2015 accord with 39000 mi. has had a starter motor fail, this apparently a common problem.
