2020 Honda Accord owner complaints

While I am driving I have experienced incidents where the (Automatic Brake System) AEB system engages unexpectedly, causing the car to brake hard without any obstruction or vehicle in front of me. This incident have happened on both highways and main roads. When my car unexpectedly breaks, sometimes I get a warning That Says Brake then the car Beeps and sometimes It won’t give a warning. Today when it happened it only braked once but like I said it happens unexpectedly. (2020 Honda Accord Sport 1.5lt)

Automatic 45mph to zero breaking with no cars or objects in sight. Almost caused a rear end collision due to faulty and unnecessary automatic breaking.

It is unknown what system failed. While coasting to slow for the stopped car in front of me, the car began aggressively accelerating without warning. Adaptive and standard cruise control were both off. Lane keep assist and road departure were also switched off. Due to the slick nature of the road, the acceleration left me traveling far too fast with little space to stop. After sliding to a stop, I was within a foot from the car in front of me. This failure very nearly caused an at-fault accident which there was nothing more I could do. Note that this happened roughly 40 mins into a drive, which was otherwise uneventful. No warning lights were present before, during, or after the issue. This car has been having phantom braking issues and power loss issues consistently since March and has s

Fuel injectors went bad and caused several warnings to pop up at one time. Vehicle begin to stall on the interstate out of nowhere. Taken to Honda dealership to confirm it was the fuel injectors.

On December 4 at 8:57pm I was driving on interstate 295 doing 60 miles an hour and my car’s warning light for breaking came up for me to break like something was in front of me even though there wasn’t, this is a continuing thing going on. I reported every time it happens.

I would like to report a known issue with the Honda Accord Sport 1.5t. My head gasket went out Aug. 2024 with about 100,000 miles on the dashboard. The cost to change it was about 4100. My Turbo Charger is now out Dec. 2025, and they are quoting me about 2100 before taxes. The dealership did advise that there is a known issue with the head gasket going out prematurely due to a default with the engine. They also advised that the turbo charger normally goes out after the head gasket is replaced. Please work on having the engine recalled. This is awful. After researching this issue, I see thousands of others are having the same issue. Best regards, Yvette J.

Driving on the freeway and the car started to lose power and de-cellerate, eventually stopping. After leaving it overnight, I returned and the car started. I slowly drove it to a dealership within 3 miles. The dealer said they could not replicate the issue. They did find a "labor diag found in history code p0304" .

Nothing happened, I just want to know if my engine is a 1.5 or 2.0

I had just left my job in Albany and was headed to the Latham area, while merging into traffic on I-90 West my 2020 Honda Accord EX-L started to rattle and slow down, numerous lights illuminated simultaneously on my dashboard. I immediately pulled off the north shoulder and restarted my vehicle to no avail, the dashboard lights were still lit and my vehicles speed and steering were compromised. My safety was put at risk due to the immediate issues as previously described while in heavy traffic, I could have easily been involved in an accident due this issue. The system Keeler Honda advised me that had failed was allegedly the head gasket leaking coolant into the engine by means of cylinder four. I was later informed by Keeler that this is a common issue with the accord 1.5 L turbo engine

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

I've noticed a very annoying humming sound while driving my 2020 Honda accord sport 1.5t. It will stop when approaching a stop or when opening the front windows. I did some research and lots of 2018-2020 Honda owner's are experiencing the same problem and mentioned it could be the anc system.

Sticky steering wheel at highway speed 70mph and when you put enough force to make it turn it jerks and you have to over correct it and go the other way to maintain in the middle lane on the highway. Takes about 10-15miles to start doing it but does not go away at all once it starts. Happens everytime on the highway

While driving at highway speeds, the vehicles steering becomes locked in place requiring a substantial amount of force to turn with the road causing the car to jerk which then cause me to over correct. There are no warning lights that have come on. The vehicle has less then 60k miles. The problem has been reproduced by a Honda dealer. They stated that they don't know how the steering rack could have failed.

While I was driving on the highway, the brakes of my car suddenly were violently activated and I had not touched the brakes. If there had been a car behind me, it would have been a major rear end collision. It was over quickly and I accelerated back to the normal speed. I talked to the Honda Service Mgr where I purchased the car and he said he was unaware of the problem although I see that that nearly 3 million Hondas have experienced this issue.

The contact owns a 2020 Honda Accord. The contact stated that while driving at an undisclosed speed, the brakes independently activated, and the transmission independently shifted into neutral. The contact stated that there were no other vehicles nearby. The brake warning light illuminated. The dealer was made aware of the failure. The contact was advised to clean off the sensors and see if the failure reoccurred. The contact stated that she did not want to see if the failure would recur. The contact was informed that the repair was not covered under the recall. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 59,660.

When vehicle is parked, and not running, trunk lid unlatches, and opens, randomly and uncommanded. This has occurred on numerous (4-5), occasions when vehicle was parked in my garage.

While driving my 2020 Honda Accord Hybrid, VIN [XXX] , the car would start exhibiting rough engine feels, and all of the dashboard lights would come on. The car would lose power at highway speeds, and I’d have to pull over to turn the car off and on. When checking on OBDII meter, getting P0301 codes. I have replaced the coils and plugs twice and still not better. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2020 accord 2.0t sport 10,600 miles I was traveling across the state with periods of light and heavy rain. About halfway into my ~280 mile trip I stopped for a red light. When accelerating from the light, my car lost power and the accelerator did not work. I coasted to the side of the road and noticed the check engine light blinking, with no other warning messages. I shut the car off and restarted to find no engine light or warning. I was in the middle of nowhere late in the evening so I continued to the destination. With approximately 20 miles to go, I attempted to accelerate around a slower moving vehicle and was met with previous problems, as well as many warning messages. Turning off and restarting the car enabled me to drive again, but the warning messages remain. Both times this
