I am submitting a safety complaint regarding my 2019 Honda Accord LX. While driving, a yellow “Brake System” warning light appeared on the dashboard. The vehicle continued to drive normally, and no obvious braking problems were noticed at that time. However, the warning remained illuminated while driving. In addition, I experienced intermittent episodes where pressing the accelerator pedal did not immediately increase vehicle speed. There was an approximately 1–2 second delay before the vehicle responded to throttle input. This occurred while the vehicle was in motion and could create a potentially dangerous situation in traffic. After turning the vehicle off and restarting it, the warning light disappeared. The issue appears intermittent. The brake fluid level is normal, and no diagnostic trouble codes were detected with a basic OBD-II scanner when the warning was present. After researching the issue online, I found multiple owners reporting similar symptoms involving brake system warnings and temporary loss of accelerator response on Honda Accord vehicles. I am concerned that this may indicate an electrical, braking system, sensor, or software-related defect that could affect vehicle safety. I request that NHTSA investigate this issue and determine whether a broader safety concern exists.

Complaint Regarding Ongoing Issues After Turbocharger Repair – 2019 Honda Accord I am submitting a complaint regarding ongoing issues with my 2019 Honda Accord after a turbocharger-related repair. The initial diagnostic code associated with the vehicle was P2563 (Turbocharger Boost Control Position Sensor Circuit Range/Performance). After the turbocharger/wastegate repair, my vehicle began displaying multiple system warnings, including: * Emissions System Problem * ACC (Adaptive Cruise Control) warning * Collision Mitigation System warning * Lane Departure/Lane Keeping Assist warning * Electric Power Steering warning * Stability/traction control warnings * TPMS (Tire Pressure Monitoring System) warning After the repair, the vehicle began jerking and experiencing a loss of power. Multiple warning lights appeared. While the warning lights temporarily cleared after a couple of vehicle restarts, they later returned and continue to reoccur. I subsequently took the vehicle to Honda, where I was informed that a sensor required recalibration. Despite having the sensor recalibrated, the issues have continued, and the warning lights continue to return. I am requesting that Honda investigate whether the repair, wiring, sensors, modules, calibration, or the turbocharger system itself may have contributed to these ongoing problems. I have also noticed that many Honda Accord owners are reporting similar turbocharger-related issues and multiple warning lights appearing. This appears to be a very common issue among affected vehicles, and I believe it warrants further investigation to determine if there is a larger underlying problem affecting these vehicles. I am requesting that Honda review this matter, document these concerns, and provide a proper resolution. Thank you for your attention to this matter.

SRS weight sensor failure-- triggers the dashboard warning light and disables my passenger airbag. My SRS light is on continuously. There is a current Honda recall for this issue for my make and model; however, do to my VIN not being listed, the Honda dealership wants to charge me a diagnostic fee plus the repair costs for the exact issue that the current recall is listed for. My VIN needs to be added. I should not have to come out of pocket to pay for this when I'm having the exact issue listed in the recall. My SRS light being on continuously is a MAJOR Safety concern because it disables the airbags--so in the event of an accident, the airbags will not deploy. I contacted Honda Corporate and they created a case--Case number 16432964 for this issue--but they told me it would be possibly months to get anything done and I would still have to pay out of pocket first. NHTSA RECALL NUMBER: 26V-332 CAMPAIGN DESCRIPTION: 2018-22 Accord, Accord Hyb Seat Weight Sensor Recall Exp RECALL DATE: 05/21/2026 I have a service appointment on XXX @830AM at the Honda of Owings Mill Address: [XXX] Phone: [XXX] I am also experiencing the phantom braking issue (unintended activation of the Collision Mitigation Braking System) when there is no object in sight. The fix seams to be updating the Collision Mitigation Braking System (CMBS), which often require software updates and sensor recalibration. The dealership wants to charge me for this as well.

When driving down a state highway in town, about 40-45mph, with no cars or objects in front of me and within the lanes - aka nothing unusual - my dash lit up with the orange "BRAKE!" warning and then slammed on my brakes. I had no idea at the time that my vehicle could even do that, as I'd had it at least three years and, while I'd had false warnings because of a line on the road or something, it had never done that. Luckily, there were not cars close behind me, because it was disorienting and took a moment to realize what was happening and adjust my driving to correct it. It was incredibly concerning, and I searched for what feature would even do that and how I could turn it off. I've told many people about it since, as it's the kind of thing that makes using "safety features" of a vehicle untrustworthy, let alone what could've happened had there been cars behind me at that moment.

My 2019 accord gets stiff at speeds over 25-30mph and resists driver input, so much that you tend to over-compensate and make constant steering corrections every second so you don't crash. The car does not track straight at any speed, and does the same when the Lane Keeping Assist (LKA) is off or on. When LKA is active the car will not go straight on a straight smooth road. The car wanders dangerously from the right to left line markers and often rides on the markers bringing you very close to other cars and then jerks the car back to the opposite side of the lane and continues to do the same back and forth like a drunk person is driving the car. Also the Driver Input Required amber light comes frequently on a straight road with highly visible lane markers. It is extremely tiresome to drive the car and try to keep it in its lane, even when I disable all the "driver-assistance" features. This is because the steering has a mind of its own and stiffens up. It resists the slightest driver input so you have to put more strength into it to make it go where you want to, but once the steering gives up fighting you and lets you do it, it results in overcompensating and constant steering corrections by the drive left-right, left-right, just going down in a straight smooth freshly paved road. It’s been over a year and the dealer has yet to detect anything wrong, they tell me my vehicle drives perfect, honda dealer after dealer.

The vehicle suddenly braked on its own without any obstruction, causing a violent stop and injury. I took it to the nearest dealership to check for a recall. They said there wasn't a recall for this VIN, although online searches show this as a known defect for 2018-2020 Honda Accord Collision Mitigation System.

There is loss of power when accelerating and all the warning lights are staying on when the car starts which is disengaging all of the advanced driver assistant systems.

While driving my 2019 Honda Accord, after about five minutes on the road, multiple warning lights suddenly appeared on the dashboard. The emission system, brake system, power steering, TPMS, ACC, hill start assist, collision mitigation, and vehicle stability assist warnings all came on at the same time. The alerts caused concern for safety, as several major systems such as steering assist, braking, and driver-assist features appeared to malfunction simultaneously. The issue seems related to an electrical or charging system failure (such as the alternator or battery), since all of these systems rely on stable voltage to operate correctly. The incident occurred without warning and could have resulted in loss of steering assist or engine power while driving

I was traveling on a two lane road at approximately 40 mph when the automatic braking engaged for no reason, bringing the car to almost a complete stop. There were no other cars from either direction.

NHTSA ODI 11691877

In 2 instances the car put on brakes for no reason. Nothing was in front of car. I was traveling roughly 70 mph and car slowed down and brake indicator came on, also going 75 with cruise control on and the system that brakes the car slowed the car down and then just quit working. Warning lights came on saying system failure but after car was turned off then turned back on there were no warnings.

Wednesday 10/01/25 I was driving to work on the highway with cruise control on, it was a empty road with nothing in front or behind me, my steering wheel got yanked out of my hands and turned all the way to the right towards the guard rail, then the steering wheel got yanked all the way to the left automatically, I did a 180 degree spin and crash my 2019 Honda Accord Touring 2.0L. I believe the Lane Keeping Assist System (LKAS) was at fault as well as the Collision Mitigation Braking System (CMBS). The vehicle got towed off the highway directly to a local body shop. The vehicle is available for inspection upon request. Mine and others safety was put at risk because the vehicle decided to crash itself potentially killing me or other people. The vehicle just arrived at the body shop and no diagnosis has been done yet. The vehicle is not drivable so the problem has not been reproduced. Vehicle has not been inspected and looked into yet, I am waiting for the body man to do a deep dive into it or I am planning on bringing it back to the dealership. There was no warning lamps present.

I feel like my car should be under recall it’s so many other who experiencing the same thing. all of my lights are on, on the dash. Check engine light down to my cruise control not working. as I drive it’s stalling and jerking. I went to the dealership to have my spark plugs and my fuel injectors replace and it started back doing the same thing. Spent thousands just to be going through the same exact thing.

During highway driving the collision system starts to brake without any risk or objects in view. Happen twice within 10 minutes

NHTSA ODI 11685597

Driving along at approximately 41 mph, CMBS unexpectedly activated for no apparent reason. There was no object in road to potentially collide with. Warning system barely activated before CMBS engaged braking very hard. Vehicle went from 41 mph to 31 mph in 2 seconds as recorded on dash cam. This is the 2nd occurrence in the same approximate location, both for no apparent reason & with no object in road ahead. Had an another car been following closely, this would have caused injury.
