2015 Honda Accord Electrical System Problems

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

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.

Getting error P2602 Low Voltage Coolant Pump. No visible sings of failure or damage to the pump or wiring. Tested power, ground, and signal and found them all to be ok. Vehicle has 133,000 miles. Engine is not running hot at all. Very cool to the touch, error P2602 causes car to go into limp mode and can not drive past 40 mph. Issue could be from Pump recalls from other honda models that used the same pump that is in the 2015 Honda Hybrids. Honda did not include 2015 Honda Hybrid in the recall when they should have, because its the same pump that was recalled in other hondas. Took the car to dealer in Auburn, WA, Hinshaw's Honda. Please get report from them. To get a second opinion took car to an independent Honda repair. Again same issue, stating pump replacement.

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!

The charging system pops up on my dashboard even though I replaced the battery charging sensor and the battery. I got the alternator check and it was good so but the car stalls on me from time to time when I take off or when am driving.

ABS Control Module with well known defects. Needs to be recalled. [XXX] . Many, many customers are having this issue, including me. I was told that the part is not available after market and the Honda Genuine part was quoted to me at $3,000 with low labor cost to the repair.

Copy from another complaint, as I am having the same issue. Issue where multiple dashboard indicator lights coming on. Tire Pressure, ABS, Power Steering, and Traction Control lights specifically all on at the same time. Car typically drives fine but will intermittently not want to accelerate

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

2015 has a bad ABS Modulator fail (Solenoid valve). My car only has ~75k miles. It seems this is a common error with 2010-2015 Honda Accords and presents a safety concern. Honda has not issued a recall.

The contact owned a 2015 Honda Accord. The contact stated that while the vehicle was parked outside, the vehicle caught fire. The authorities were called to the scene and extinguished the fire. Upon inspection of the vehicle, the fire department determined that either the battery wiring and/or the roof wiring had caused the fire. The vehicle was towed to an independent tow yard where it was deemed a total loss. There were no injuries or property damage as a result of the fire. The dealer was notified of the failure. The manufacturer had yet to be notified. The vehicle was deemed a total loss. The failure mileage was approximately 92,000.

Issue where multiple dashboard indicator lights coming on. Tire Pressure, ABS, Power Steering, and Traction Control lights specifically all on at the same time. Car typically drives fine but will intermittently not want to accelerate and/or brakes are trying to apply themselves while trying to accelerate. This is a dangerous safety issue as I could be driving on the highway the car all of sudden would not continue accelerating. Short term Workaround is turning Traction Control off but does not last. In general issue seems to be electrical. Could be battery, ABS Module needing a reset to neutral, wheel speed sensors are bad, PCM Module faulty, fuel pump failing, VSA issue or needing a reset, faulty wiring, or a combination of all of these mentioned. I took to a Honda dealership (Mall of GA) and they could not resolve the issue and recommended a VSA Module replacement which is a $2000+ repair. This issue came up for me in mid-July 2023 and as of this post is still an issue. This should be recall as I keep seeing complaints about this online in various forums for 2012-2017 Honda Accords.

Problems began at 50,000 miles and now at 60,000 a year and 1/2 later they are ongoing . Electrical and engine …. Honda knows all the problems bless I am having are in many of their models! This is DANGEROUs and Honda is negligent ! First it was my car wouldn’t start. The alternator went also It needed to have the front and rear seal replaced . That is crazy ! It must be leaking oil and needed the seals due to improper torque. Had that repaired and within 2 weeks I kept saying it wasn’t running right. THEN My car overheated after driving for 10 min on a busy highway in Atlanta. Smoke pouring out of the hood. I was trapped and couldn’t get out because of traffic. HORRIFIC experience.! Electrical issue began at 50,000 miles at the same time . Electrical issues ongoing AND engine does not run right. It’s rough loud , judders , it can be sluggish or no responsive, Last year my car had 50,000 miles. It had gone through a battery every year and 1-2. Then 16 months ago it wouldn’t start. Since I have replace the starter , alternator , battery and battery cable. In individual events of warning lights or failing to start. Today the charging systems warning light and fcw light flashed while driving. The electrical system in this car is a known problem. It MUST be recalled. The 4cl has now time to recall the v-6 for torque and parasitic battery drain . This is potential for fire , car sudden loss of power it’s negligent to not recall . I have invoice after invoice but the problem persists . Why are you only recalling the 4L engine ? There is a class action about battery drain but only for 4 L? I know the didnt produce many accord V6 but the V6 is used in the Acura and I believe the Odysse. I have called and called Honda . I emailed the head of Honda in Japan . He sent my email back to the dealer. This is my 4th Honda. We were an entire Honda family but not any more . Safety is not first .My accord problems will result in a terrible accident . Please do something

I’ll start by saying my car is impeccably maintained at the Honda dealership! I have reached out to Honda and even emailed the hard of Honda motor corp in Japan and my cars problems. In the last 16 months my car has trouble starting , failed to start on several times , and for [XXX] reason the battery charging issue light comes on , as well as forward control warning light . It began last spring 2022. I need the main and rear seal replaced , a new battery eve though mine wasn’t a year old and was purchased and installed at the Honda dealer, it also needed a new alternator. Within 10-15 minutes of driving all the dashboard lights flashed smoke poured out of the engine.the car overheated while I was driving in the highway ! I was stranded in busy highway traffic . I also had a new battery cable replaced. That was between march and April of last year. All is documented and reported to Honda. Highly unusual for a 7 year old car with 50,000 to need 2 seals, a new battery each year for 3 years in a row , a new battery cable , and alternator . I also reported the car isn’t driving well . 1 year later and I need another alternator and a starter! In March The car wasn’t starting it made clicking noises - it needed a starter and now in July it the battery charging issue light was again flashing and needed another alternator . My car is nether safe nor reliable . There is no doubt my car has MAJOR electrical issues that are ongoing and unresolved.it is NOT just my Honda accord.the records show this.Please do something .I can not afford a new car . Honda says they are about safety but they are NOT ! With so many ongoing electrical problems it is not if but when something will happen. I’ve made it clear to honda and now you that we the consumer need help from the ongoing honda electrical issues plaguing the accords before there are fatalities. Also, do more psa letting consumers know they need to report issue on your site- o didnt know and I am pretty savvy .

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.

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.
