general problems of the 2020 Honda Accord - part 1

9 warnings lights turned on on my dashboard and when going slow and accelerating it brakes by it self also brakes on freeway going 70 mph and then recovers.

My car shut off on the road. I tried to accelerate but all my lights on the dashboard came on. I wasn’t able to accelerate more than 20mph. I was about to make it back home. Today I tried to take it out on a test drive, it’s drivable but I was not able to accelerate. Every time I pressed the gas, my car would stall. This is the 4th time it happened.

Engine,coolant system vehicle was cutting off in the middle of driving shaking and jerking.

All the indicator lights are activated on the dashboard. They go off after disconnecting the negative battery terminal bit CO. E back on later.

I have constantly had to replace spark plugs within the last year — all lights are on dashboard. Finally took it and got a p0372 code, rough idling and misfiring, and stalling. Car once cut off on me while driving. Took it to the Honda dealership and it is indeed my fuel injectors and gasket. I have tried to get in touch about a possible recall but the Honda manufacturer are failing to release a recall. With all lights on dashboard, no features of the car can be used (cruise control, road departure, lane keep assist, collision mitigation, hill start assist, traction control, brake hold, and tpms) I’m looking forward to a recall coming as soon as possible. I have done my research and thousands of people are having the same issue, it is frustrating especially with the cost of work having to be done. Nobody should have to purchase a new car because of a defect of the manufacturer or too lazy to investigate the issue. Honda salesmen and mechanics all say the same thing about the 1. 5l sports model. Over 3,400 worth of work due to a problem I did not cause.

Car has recently started to actuate the door locks while accelerating from a slowing or braking position. There was some clicking or chattering under the steering wheel that may be a symptom before this started happening. It sounds a lot like the recall for other Accords on the control module. Either way, the car should not be actuating the locks when accelerating from a slowing or braking situation. This is not normal and could be life threatening if in an accident.

The touch screen radio will randomly start pressing itself, it’s a major safety issue. You can be on a road trip with the gps on the screen and it will randomly go to settings causing you not to be able to see where you need to go next. This is a constant problem I deal with everyday.

All lights have popped up on dash. Stayed on for 2 days back in July and then went off. Came back on 2 days ago (oct 5th) and have not went off yet. Lka, cruise control, parking brake light, tpms, traction control, and engine light.

The vehicle keeps braking automatically with nothing in front of me, I see numerous people reporting it so I figured I should aswell, nothing in front or near me when it automatically brakes, it is scary as heck tho!.

Good morning, I have new Honda Accord 2020 which always been taken care of regular services and oil changes etc. This morning I tried to start my car going to work but suddenly all brake related warning signs came off. My card still not starting the engine. I researched online and found out many people who have same Honda facing same issues. So I figured it's better to be reported before someone gets really hurts while on road. Please find attached pictured with this incident report please.

I am reporting a potential safety issue with my 2020 Honda Accord touring hybrid. On September 4, 2025, my dealership identified a non-genuine purple quick-splice connector in the driver’s door harness, which they attribute to error codes b1142 (driver’s door lock knob switch circuit), u0199 (lost communication with driver’s door module), and u3003-16 (electric servo brake control unit power source low voltage). This connector, not installed by the recent audio installer who put only upgraded speakers and deemed non-Honda, may be an aftermarket modification (possibly an alarm/tracker or anti-theft device) causing electrical faults. While no water was found, the issue could impact brake assist (u3003-16), posing a safety risk. I request NHTSA investigate whether this reflects a widespread manufacturing or modification defect, especially given reports of similar quick-splices at dealerships for repos or fleet locking. A reddit user said, “ we see these at our dealer frequently. Those are quick-splices, usually used to piggyback off your oem wires to supply voltage/signals to an aftermarket alarm/tracker. Other dealerships install this in the event of repos/auto locking an entire fleet/or additional anti-theft. ”.

Electrical drain in system causing premature battery failure and electrical misfiring that causes the car to shut off and flashing a brake warning message to contact dealer and once this occurs car won’t start until Honda link and hands free pairing are reconnected. Issue is if the misfiring drains the battery, driver is not able to reconnect the cars apps and pair the bluetooth, therefore, car is not will be immobile until battery is recharged.

The contact owns a 2020 Honda Accord. The contact stated that when attempting to start the vehicle, it would rev up and take an extended 15-second start before starting. The vehicle was taken to the dealer, who was not able to duplicate the issue; however, did presume that a defective fuel system caused the failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 48,000.

Malfunctioning fuel injectors causing misfires stem from a known issue with faulty fuel injectors; a problem widely reported across multiple Honda models equipped with the 1. 5-liter turbocharged direct injection engine. Notably, the Honda cr-v (2019–2023), civic (2019–2022), and Accord (2018–2022) have all been consistently linked to fuel injector failures. The most serious safety concern associated with this defect is the potential for sudden throttle changes, which can trigger the check engine light, cause the engine to lose drive power, hesitate, or even stall—all of which significantly increase the risk of a crash or injury.

Multiple warning lights on the dashboard come on and stay on including but not limited to check engine light, abs, break lights ect….

While diving at highway speeds (first at 55mph in may 2025 and then again in July 2025 at 65mph) I got a warning on screen about power loss and a critical failure and that power will be reduced and to stop at the side of the road. Within 30 seconds or a minute of the warning the car power cut out significantly impacting the speed and both times almost causing traffic behind me to hit me from behind. I took it to Honda dealership in dulles, va back in may 2025 and they told me it was the electric water pump which I had replaced. Now in July it happened again and this time I had my wife and child with me in the car as well as a guest. I had to pull over and all the warning lights started to flash (everyone of them). I have taken it back to Honda but having a car that goes from 65mph to 25mph on the highway with no warning to others is a recipe for disaster. Apparently this is a known issue with the hybrid system and the battery needs replaced (from online Honda forums) which Honda is not doing unless forced. I am still waiting for my dealer to get back to me but its exactly the same problem as the other notes I saw online. My car only has 46,000 miles.

The Honda infotainment system, does not respond to touch, and randomly changes screens as if someone is pushing buttons. It randomly switches to the phone, contacts, music, bluetooth connection, and navigation. When using navigation it moves the map and brings up routes. This can cause significant distractions to the driver. Multiple individuals have reported this issue to the dealer.

This engine has been so poorly designed it leaks coolant into the engine system. I am extremely frustrated and disgusted with the dealership and Honda for knowing these engines are defective yet still producing/selling them. We pay hard earned money for something so unreliable it’s actually insane. I don’t want to be nasty about it but someone needs to say something.

I continue getting a message supplemental restraint system problem. See your dealer. Also, many times not all my doors lock and I have replaced the battery for key fob numerous times and no luck still while driving I hear a noise as if the doors are locking or unlocking on its own.

Brake system light keeps coming on.

A supplemental restraint message is occasionally flashing on my dashboard.

Right front turn signal does not work also fm/am radio does not work as well as trunk release button on trunk itself. Had both head lights replaced thinking it was an led issue with turn signal and was told by mechanic that bcm is the issue. Called Honda regarding the recall to the bcm and was told my car is not apart of said recall because it didn’t come from a certain region but seems to be all of Honda Accords have this issue regardless of plant manufacturer.

My blinker won't appear on the dash. My trunk won't open. My back up camera won't come on at all. Can't adjust my exterior lights, stuck on the dimmest setting and can't change. Lights will also flicker and I have no control over it. My radio screen told me to enter a code but wouldn't allow me to. My break system light was on. There is warning reading adaptive cruise control see dealer, automatic emergency braking see dealer, lane departure warning see dealer. Doors locked and unlocked while driving. Air condition wasn't blowing the temperature it said, and acting as it was on low when it was on the highest setting. It is available for inspection upon request. I brought my car into a Honda dealership today. My car had to stay overnight because they were unable to address the problem. There were no prior problems or warnings beforehand. All these problems first appeared when I started my car for the first time on November 14, 2024. These put myself and others at risk because the doors locked and unlocked which could have caused us to get trapped in. The lights not working put me at risk at night because I could not see the road that good.

Starting sconce July the car will vibrate at random times and will hesitate and buck while car will vibrate and not want to move have brought the car back to the dealership over 4 times now and they can not find any issues despite me having videos and any information I can gather since July if 2024.

10 months after purchasing my vehicle from the dealership, all lights illuminated on the dash, it goes through each warning every time you crank. This would not go away. I took it to the Honda dealership during a recall and they said they could not find the problem. Suddenly this week, after owning this car for 2 years and being told the issue could not be found, and only 90,000 miles, the car made a sudden stop on the road almost causing an accident. The car would not move forward or reverse. We had to have it towed to a dealership and waiting to hear issue. This is an extreme hazard! and I may be stuck with a costly bill once again, with no resolution.

During a forward-side lane departure collision in my 2020 Honda Accord, the body control module (bcm), forward collision radar system, braking assist, and vehicle stability assist (vsi) all failed to activate. As a result, the vehicle did not brake, warn, or stabilize before impact. The airbags also failed to deploy during the crash. My safety and the safety of others were put at serious risk, as the vehicle did not respond as designed despite being equipped with these systems. The car is now undrivable but available for inspection. This issue has not yet been confirmed by a dealer due to the car's condition, but similar failures have been reported in other 2020 Honda Accords already under recall. The insurance company did not request vehicle data and did not inspect the systems. There were no warning lamps, alerts, or messages prior to the failure; the malfunction occurred without notice. I am requesting that this vehicle be added to the existing recall list related to bcm and safety system failures.

Bought the car back in 2020 after less than a year electrical problems caused the car to malfunction got it fixed and constantly after that more electrical problems changed the sensors and the car still continued to lose power. While driving on the highway the car completely lost strength and would not let me drive more than 25mph check engine light started blinking as well as all the lights lkas acc tpms and more.

I received a recall notice that there is a safety recall on my vehicle for a circuit board under the passenger seat. Manufacturer recall #xhp, NHTSA recall number 24v064. I utilize my vehicle to provide a source of income. My local dealership informed me after I called them that there was currently no remedy to the problem. This is a major inconvenience that now I can no longer make the extra income I need. Does this problem affect my vehicle as a whole? is this really a safety problem? I need documentation stating this is not a safety recall, thank you.

The anc module malfunctions already at only 67000 miles and causes a humming noise which is very annoying when driving. The ebreak also malfunctions during cold weather conditions. I have had to restart the car due to the electronic parking break not working properly. In case of an emergency I might need it and it may malfunction.

The contact owns a 2020 Honda Accord. The contact stated that while driving at an undisclosed speed, several unknown warning lights illuminated, and the forward collision avoidance message was displayed. The vehicle was taken to the dealer. The contact was informed that the radar sensor, located on the front bumper, indicated that the vehicle was involved in a crash. The contact stated that the vehicle was not involved in a crash. The vehicle was repaired. The contact stated that on a separate occasion, while driving at an undisclosed speed, the vehicle experienced phantom braking twice. After several minutes, the vehicle returned to normal functionality. The “brake” message was displayed. The contact stated that the failure had occurred while driving on the expressway. The vehicle was not taken to the dealer or an independent mechanic to be repaired. Most recently, while driving at an undisclosed speed, several warning lights were illuminated and remained illuminated. Additionally, the cruise control and lane departure warning lights failed to function as intended. The vehicle also failed to accelerate as intended while depressing the accelerator pedal.

The dealer diagnosed and determined that the transmission needed to be replaced. The vehicle was towed to a transmission specialist, where the transmission was replaced; however, the failure persisted. The contact related the failure to NHTSA campaign number: 20v771000 (electrical system, back over prevention, visibility/wiper, visibility, exterior lighting); however, the VIN was not included. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that they could not assist due to the mileage on the vehicle.

I am writing this letter to complaint about a major defect for my vehicle as the Honda dealership located at 1036 jericho turnpike , huntington NY doesn’t want to resolve as the vehicle is still under the manufactory warranty. The defect / problem involves the emergency brake release switch located in the center console area . I reported the defect / problem and hoped that Honda would honor the manufactory warranty under 36, 000 mile policy to replace an or repair any defects without cost to the consumer . However I was informed that payment in the amount of seven hundred and fifty dollars would be needed to resolve / repair the problem/ defect. I was told that the clip that hold the switch/ device to the center comnsole were broken and it is the current owner problem to resolve as it not covered. Just imagine how could I be responsible for a broken clip , when you look at the picture its clearly not a owner error but rather a defect in the workmanship to properly secure switch to the console . I want Honda to honor the under 36, 000 mile manufactory warranty policy and fix this problem without having me as a consumer to pay . Attached are the pictures of the emergency switch resisting inside the center console as no visible damage to the supporting outside structure .

Without driver intervention, the vehicle engaged the brakes. Threw both passengers forward until the seat belt restraints engaged. Bruising both passengers shoulders. The vehicle would not respond to either pedal - brake or gas for a few seconds. There was no visible traffic in front of us. The day was clear. And no construction or overpasses. The vehicle was taken into a certified Honda dealer and inspected. No “flags” or diagnostic issues found. The car was driven by the dealer. The issue wouldn’t reproduce. The dealer stated that they did find a large “smashed” bug on one sensor and wondered if it could have caused the issue. Prior to the vehicle initiating the panic stop, no indications of a event were posted on any device in the vehicle.
