Honda Accord won't start problems

Filed Oct 15, 2026 · Electrical · KS

1. The service center diagnosed the BCM as faulty. I do not have the faulty part available as it was replaced. Service center work notes: Vehicle no start confirmed, battery voltage is at 12.4V. Vehicle has message on dash to touch key to ignition start stop button, with no success. Proceeded to inspect all main fuses to under hood fuse box, found all fuses are good main 175 amp fuse is ok, along with all four multi fuses. Proceeded to follow troubleshooting for message displayed on dash, tested key fob for unlock and lock functions, tested start stop button functions with no issues. Checked fuses that power is at each supply pin, pin 1 on connector a has 12.2v and pin 18 12.3v. Used the ground from connector pin 51 while testing voltage on previous pins to confirm ground is good. It is suspected that bcm has a internal failure and will need to be checked with known good unit, reprogrammed and retest to confirm vehicle will start. 2. The car in the faulty condition had no noticeable difference from one with a low battery so I tried to jump start the vehicle per the owners manual. This put me at a significant fire risk of over charging the battery. 3. Unknown if the manufacturer, insurance or police inspected it. 4. No warning lamps prior to failure. Dash was entirely blank other than aforementioned instruction about the key fob.

I am reporting repeated, unpredictable loss of engine power and propulsion in my 2019 Honda Accord Touring 2.0T (approximately 146,000 miles). The exact cause remains UNKNOWN. On XXX, while driving on [XXX] near [XXX], my vehicle suddenly lost acceleration at highway speeds and eventually stalled. The vehicle repeatedly lost power, experienced crank-no-start conditions, and at one point could barely maintain 10 mph. I was stranded and had to have the vehicle transported to a Honda dealership in [XXX]. Diagnostic code P0087 (Fuel Rail/System Pressure Too Low) was recorded multiple times, including at 70–74 mph. Numerous warnings appeared, including emissions, brake system, electric power steering, stability assist, adaptive cruise control, collision mitigation, and road departure mitigation. The unpredictable loss of propulsion creates a serious collision risk, especially on highways and in traffic. The Honda dealership initially could not reproduce the failure. After replacing the spark plugs at my expense, the vehicle was returned to me. Approximately 23 miles later, the malfunction returned, and I immediately brought the vehicle back without clearing any codes. Honda subsequently diagnosed and replaced the high-pressure fuel pump at my expense, but the loss-of-power issue continued. The vehicle previously received Honda’s in-tank fuel pump safety recall repair in May 2025. Despite that recall remedy and subsequent repairs, the vehicle continues to malfunction. The exact cause remains undetermined. The vehicle has been inspected by an authorized Honda dealership. Repair records and diagnostic information are available, and the vehicle can be made available for inspection upon request. I am requesting an investigation into this recurring safety-related loss of propulsion. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

this has actually been a problem since I first got the car in 2015 but probably started happening in 2016. but it happens so intermittently that I hardly thought about it or figured it just needed a new battery. but I changed the battery and it is still happening where the car won't start. I have to push the button repeatedly or put the car in N to get it to start. eventually it works but I'm worried about an electrical issue causing a fire. when it doesn't start all the lights on the dashboard light up. I keep trying and eventually it works. as I said, I'm afraid it will cause a fire. I called honda and they said some cars were recalled for starter issues but not my vin number. seems like if other Hondas had issues mine would too.

My parked 2020 Honda Accord had a spontaneous side curtain airbag deployment with the engine off, which matches the known humidity/short-circuit sensor defects that are currently under Federal safety recall. The deployment caused damage to the interior of my car, as well! There have been no warnings, indications or issues before. There was no collision or impact of any sort. The car will not start and had to be towed to Hugh White Honda, Columbus Rd. Athens, OH. The service department reported that they can’t find the “why” of how it occurred, nor would they be able to repair the damage that occurred from the airbag deployment. The insurance agent said without visible “cause” they will deny any claim.

I experienced repeated stalling, loss of drive power while on the highway, limp mode, and all dashboard warning lights over several years. I brought the vehicle to an authorized Honda dealership multiple times and specifically asked whether these symptoms were related to the known fuel pump recall. Each time I was told the recall was not the cause. I was also told recall parts were unavailable or delayed. Based on dealership misdiagnoses, I paid out of pocket for multiple repairs including spark plugs and ignition coils which they claimed were the reason for my car acting up, that did not resolve the issue. Among other repairs I did on my own like replace the battery twice and what not. I have since received Honda’s official recall notice confirming that a faulty fuel pump causes the exact symptoms I reported. My vehicle is now completely inoperable it does not start and cannot be driven or transported. I have filed two claims with Honda Corporate, both denied based on mileage. I believe the vehicle’s failure is a direct result of Honda’s failure to address the recall in a timely manner and the dealership’s repeated misdiagnosis.

The engine stop/start system on my 2016 Honda Accord, VIN [XXX], has stalled and shut off without warning in active Los Angeles traffic dozens of times since September 2025. The vehicle loses all power mid-drive with no warning — no dashboard lights, no warning sounds — leaving me unable to accelerate or respond to surrounding traffic. The condition has progressively worsened and now includes repeated no-start failures requiring three documented tows. The component failing is the engine stop/start system. The vehicle is available for inspection upon request. My safety and the safety of others hav been put at risk repeatedly. I am a [XXX]. My wife, age [XXX], has [XXX] and has been a passenger during stalling events. Sudden unexpected stalling in active Los Angeles traffic creates immediate foreseeable risk of rear-end collision and loss of vehicle control. This risk has been experienced dozens of times over six and a half months. The problem has been presented to Honda of Hollywood, a certified Honda dealer at 6511 Santa Monica Blvd, Los Angeles CA 90038, across five separate visits. Each time the dealer concluded no problem could be found. On one visit I was charged nearly $2,000 for spark plugs and a gasket — work with zero diagnostic connection to the stalling complaint. The vehicle was returned to me in an unsafe condition after every visit. On [XXX] the tow truck driver who responded to my third documented tow independently experienced the failure, could not start the vehicle, witnessed the complete failure sequence, and declared the vehicle unsafe to drive. He is an independent third-party witness with no stake in this case. I have video documentation of the vehicle stalling in active traffic on multiple occasions. I have voicemails from Honda of Hollywood's own service advisor documenting their diagnostic failures. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle experienced a catastrophic engine malfunction resulting in a no-start condition. The vehicle is currently inoperable and is available for inspection upon request. The engine failure caused the vehicle to lose power and become unreliable, creating a risk of breakdown while driving, which could have resulted in being stranded in traffic or an unsafe location and posed a risk to my personal safety and the safety of others. Yes. An independent repair facility confirmed the vehicle would not start and diagnosed the engine as failed. The vehicle was subsequently towed to another facility, where the condition was again documented. The vehicle has been inspected by independent repair facilities. The extended warranty company, Route 66, reviewed the claim and denied coverage based on their assessment. No inspection by the manufacturer or law enforcement has occurred. Prior to the failure, the vehicle exhibited warning indicators and operational issues, including overheating symptoms. These issues worsened over time and ultimately resulted in complete engine failure and a no-start condition.

I noticed random misfires months ago. I've replace my spark plug three times in 6 months. My coils are good, etc. It started getting worse about a month ago. It goes into limp mode and suddenly slows to 20 mph. Some days it won't start. The dash lights flash and the cars computer goes crazy it won't go over 20 mph. This is a widespread issue causing ppl to spend thousands and no fix in sight. Usually it hits between 15-90k miles. Twice I was on the interstate and it just slowed to 20 mph. I have had it at the dealer twice. They are clueless and can't do much without Honda stepping up. Honda needs to address this. My car was built in 2021 and somehow missed a major recall. It's putting stress on my catalytic converter and other parts that cost thousands to fix. I'm taking it in on Monday for the third time. If they can pinpoint it this time I'm afraid it might cost me thousands. It's a Honda and it shouldn't be having issues from 15k to 90k.

Car won't crank lights on dash on. KEEP saying ABS Braking system.
