2020 HONDA ACCORD Electrical System Problems

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

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...

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.

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...

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

ENGINE,Coolant system VEHICLE WAS CUTTING OFF IN THE MIDDLE OF DRIVING SHAKING AND JERKING

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.

A supplemental restraint message is occasionally flashing on my dashboard

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.

The contact owns a 2020 Honda Accord. The contact stated that while driving approximately 30 MPH, several unknown warning lights illuminated. The contact pulled over and turned off the vehicle to reset the instrument cluster; however, the warning lights remained illuminated. The contact checked under the hood to check if the battery terminal was loose, but found no issues. The contact had taken the vehicle to an independent mechanic who replaced the 12-Volt battery; however, the warning lights returned. Additionally, the contact stated that while stopped at a traffic light or while depressing the brake pedal, the vehicle was vibrating. The contact had not taken the vehicle to a local dealer or to an independent mechanic to be diagnosed or repaired. The contact had stopped driving the vehicle. The contact stated that prior to the instrument cluster failure, the low-pressure tire monitor warning light was intermittently illuminated. The tire pressures...

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.

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.

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.

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...

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

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

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.

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

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.

Brake system light keeps coming on

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...

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.

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.

The contact owns a 2020 Honda Accord. The contact stated while driving at 25 MPH, the front driver's side air bag, the front passenger's side air bag, and the knee air bags were deployed unintendedly. Additionally, there was a significant amount of chemical smoke inside the vehicle. There was no warning light illuminated. The contact stated that she depressed the brake pedal to stop and exit the vehicle, but the vehicle failed to respond. The contact stated that the vehicle rolled for 30-40 seconds and stopped after hitting a bicycle pole. The contact stated that the front passenger's side seat was occupied by an adult and the rear seats were occupied by an adult and a baby in the car seat when the failure occurred. The passengers sustained body aches and ringing ears but did not seek medical assistance. The contact stated that she parked the vehicle, and then all...

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.

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 contact's father owns a 2020 Honda Accord. The contact stated that following a short drive, the vehicle was parked on the street. The contact said that neighbors tried to alert him that the vehicle was on fire. The contact is hearing impaired and did not hear his neighbors knocking on his door. The fire department was called by a third party and extinguished the flames. The contact stated that the fire department left a note on her father's front door explaining that the fire had started under the driver's side front tire wheel well, then proceeded down the driver's side and was extinguished using water by the driver's side rear wheel well. The right passenger side of the vehicle was not damaged by the fire. There were no injuries. The fire department wrote a report and determined that the fire was an electrical system failure. The vehicle was not...

The contact owns a 2020 Honda Accord. The contact stated while driving 25 MPH, the messages "Lane Departure. See Dealer", "Engine Problem See Dealership”, “High Beam Problem. See Dealer" and other unknown messages were displayed. The vehicle was towed to the dealer, where an unknown fuse was replaced; however, the vehicle started temporarily but the failure recurred. 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. The failure mileage was approximately 84,000.

This is the third Accord I've owned, and none of them have been issue-free, but this one (2020) is the worst. I bought this car in March of 2021 with only 6 miles on it. Within a week it started to throw occasional notifications, which I called the dealership and asked about. They assured me that it was just a hiccup and to bring it in for a factory reset. They performed this reset, and the car appeared to be fine after that. BUT - Less than two weeks later, it started showing the four LKAS/CMBS lights and dash prompts - brake system problem, road departure mitigation system, collision mitigation braking system, and adaptive cruise control system 'problems', each saying 'see your dealer'. Made an appointment to bring it back in, and on my way to the dealership - having the car for only one month at this point -...

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...

Several times my car has slammed the brakes on its own when I have not touched the brakes and also when there is no car in front of me for it to detect the need to brake. The most recent time on 4/8 on the freeway.

While early driving in early December 2021 in my almost new car (7000+ miles) most all the lighted problems that could occur with an old vehicle lit up like a Christmas tree on the dashboard. Most of the items may or may not have actually quit working but their problem lights stayed on. Still it is no fun driving without cruise when your wife has breast cancer and you have have to drive 3 hours each way to Gainesville, Florida for treatment. I assume all the warning lights functions still worked, but it is hard to tell if things like the brakes were pr were not working when driving as they seemed to work fine. So I soon afterwards took the car into the dealer on December 11, 2021 in Leesburg, Florida. But by this time all the dash lights remained off as they are supposed to. So all they...

I LEASED MY VEHICLE A YEAR AGO, I HAD ELECTRICAL ISSUES WITH MY OLD CAR SO I WANTED A BRAND NEW CAR THAT WAS RELIABLE AND SAFE FOR ME AND MY CHILDREN. IN THE FIRST MONTHS THE CAR WAS FINE BUT AFTER ABOUT 4 MONTHS THE CAR WOULD SMOKE FROM THE EXHAUST PIPES RANDOMLY. I TOOK IT FOR MAINTENANCE AS THE CAR SYSTEM DIRECTED BUT THE REPAIR SHOP NEVER SAID THERE WAS ANYTHING WRONG WITH THE EXHAUST SYSTEM. A MONTH OR SO PAST AND ONE DAY I GOT IN THE CAR AND ALL THE LIGHTS ON THE DASH BOARD WERE IN. I WAS SO FREAKED OUT BECAUSE IT WAS A NEW CAR AND NO WARNING LIGHTS SHOULD OF BEEN ON. I TOOK IT TO HONDA REPAIR SERVICES AND THEY FOUND OUT THAT A MOUSE WENT IN MY ENGINE AND CHEWED SOME OF THE ELECTRICAL WIRES. THE COST OF THE REPAIR...
