What 609 owners told NHTSA about the 2015 Honda Accord Hybrid

I own a 2015 Honda Accord EX-L V6 3.5L that I purchased brand new from the dealership with zero miles. I’ve taken excellent care of the vehicle, and because I typically drive short distances, it only has 93,000 miles as of June 2025. Despite the low mileage and proper maintenance, the intake manifold plenum (part #17160-5G0-A00) now needs to be replaced due to significant deterioration. The material used for this part is poorly made, it corrodes and breaks down over time, causing vacuum leaks. This is a well-documented, widespread issue in Honda vehicles globally. In my case, the deterioration has caused performance and safety concerns and has rendered my car undrivable. To make matters worse, this part is on national backorder with no estimated delivery date. I’ve contacted numerous dealerships and suppliers with no success, leaving me without a working vehicle or timeline for repair. I rely on this car for transportation, work, and daily responsibilities. It is extremely frustrating that a critical engine component is both defective and unavailable, especially when so many other Honda owners are facing the same problem. I am filing this complaint to raise awareness and request a timely investigation and resolution.

The contact owns a 2015 Honda Accord. The contact stated that after starting the vehicle, the engine made an abnormal ticking sound. The vehicle was taken to an independent mechanic, where an oil change was performed; however, the abnormal ticking sound became significantly louder. There was no warning light illuminated. The independent mechanic informed the contact that the engine had failed. The contact stated while driving 45-50 MPH two hours later, the failure recurred, and the vehicle shuddered and stalled in the middle of the road. The contact was able to restart the vehicle and drove 50 feet into a gas station driveway, where the vehicle stalled. The vehicle was towed to the residence. The Subaru dealer where the vehicle was purchased from, was contacted, and informed the contact that the vehicle was not covered under an Extended Warranty due to the mileage. The contact related the failure to NHTSA Campaign Number: 15V121000 (Engine and Engine Cooling). Additionally, the contact stated that the Forward Collision Avoidance Warning light was illuminated. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The contact was awaiting a call back from the manufacturer. The failure mileage was approximately 101,000.

Upon starting the car (54,000 miles) the ABS Light, Steering light, FCW, LDW, Brake light came on. After looking in the manual it was determine that the car was dangerous to drive. I did not experience anything indicating an issue with the car before this happened. I took it to Scott Clark Honda right away. The dealer preformed a diagnostic test which showed the Anti lock braking system Solenoid Value was Malfunctioning, the Electric Power Steering was experiencing a problem in the "VSA" System, the Forward Collision warning, and Lane Departure warning were showing a "VSA" Brake Actuator Malfunction. The car was underivable without getting this repaired. Because the VSA Solenoids are built inside the ABS Modulator they can not be replaces separately. The cost to repair this $2764 the part cannot be replace without a $150 Brake Fluid exchange. The initial Diagnostic fee was $30. The out of pocket expense to drive the vehicle was $2944 plus tax and shop fees. There are multiple complaints regarding the same issue. Please issue a recall. I would like Honda to reimburse me for the repair costs.

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.

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 .

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

Multitude of dash warning lights are on. Honda dealership says the Modulator assembly needs replaced. They say its backordered and have no idea when to expect it. I have seen on the internet that other customers are asking the same question. It seems dangerous since I have no idea or what safety systems are working.

While driving home from work, taking my usual country highway, suddenly my car took a sharp turn out of nowhere. I did not brake but tried to steer myself back to my lane. The vehicle jerked that direction, then jerked back the other way. I went back and forth four or five times before very carefully slowing down and pulling the car to the side of the road. Thankfully, no other vehicles were beside or coming toward me, or I am sure this would have resulted in an accident. Multiple dash symbols were lit up and remained on after turning off the car and on again. These were Vehicle Stability Assist, Electric Power Steering, Low Tire Pressure, Forward Collision Warning, and Lane Departure Warning. I waited on the side of the road until a tow truck could pick it up. The service center told us after their test drive that there is nothing wrong with this vehicle. Nothing has been done, and I fear the next time the vehicle decides to "act up."

Warning lights on dash (ABS, Brake, Steering, FCW, LDW, Slip/traction control) all came on at the same time, every time I started the car. Brought to Holler Honda Winter Park, FL and they diagnosed as having faulty VSA modulator-control unit. Part has not been available for over 2 years and don't know when will be available. Dangerous, but told fine to drive car just not to jam on brakes! Doesn't sound safe to me. NO stability control! Miraculously found Honda part at Honda dealer in NJ by searching online after Holler gave me part number. Paid over $900 to buy part/shipping. Brought to Holler to fix. Within 2 weeks had 2 VERY close calls where drivers cut right in front of me almost causing collision and causing me to have to jam on my brakes. BUT...FCW and ABS didn't work. FCW never alerted me to possible collision (used to work perfectly for over 7 years I've had the car) and ABS did not work (brakes locked up and I skidded but miraculously stopped in time). Brought back to Holler Honda and they plugged it in to computer and 1st told me that I had turned off the FCW (I wouldn't know how to do this even if it were possible), then when they could not show me how to turn it back on (because I don't have the ability to turn it off) they told me I must not have FCW (I do) and that the ABS was working just fine (it's not). After speaking with HONDA NA and sharing the info with them, they told me that I did in fact have FCW and that no one could find anything wrong with the car. I think I bought a bad "new" VSA mod. but since Honda refuses to issue a recall when I told them about the problem, I will never know and now can't do anything about it. I know I'm not the only one driving around with a potentially dangerous car because this repair cannot be done and there is an "indefinite, nation-wide waiting list" on the part (due to supply issues). Spent over $1400 to basically have all the warning lights turned off and the car NOT repaired.

While driving my FCW lights came and said failure. I took my car to an independent service center and they confirmed that many Hondas with the same year have had this same problem. Told me that he wouldn't even be able to repair because the part needed to fix the light from coming on was unavailable all across the world. So many Hondas have had this same issue and needed to repair this issue that it's unavailable. I had the car less than one year after I bought it used with less than 95,000 miles. I've owned 5 other Honda accords that would go forever and have 200,000+ miles without any issues. I've already had to place my alternator 5 times and starter as well.

April 2021 while driving dash guages stopped. No speedometer, no rpm, no temperature. Flashing fcw system failed began to flash. Multiple warning lights appeared. Check engine, power steering, break, abs, fcw, ldw, airbag, vsa and tpms. Honda of Gainesville in Florida has had my car for almost a year. No fix. Replaced engine harness, engine fusebox, computer, and cluster. To no avail. Now they say I need an interior fuse box and entire interior wiring harness. I believe they are just guessing at this point. According to honda internet forums this is a common issue with many years and models. No fix. This has been reported by many honda owners as a safety issue that should be recalled. It is incredibly unsafe to drive this vehicle with all these systems in fail. Please review. Photos and documents attached.
