I own a 2019 Honda Accord Touring 2.0T with approximately 75,500 miles. I brought the vehicle to Ryan Honda in Monroe, Louisiana, for Honda Campaign 26-091, which involved a software update to the ACC/CMBS Honda Sensing system. Before this campaign was performed, the vehicle had no ABS, VSA, brake-system, adaptive-cruise-control, collision-mitigation, or related warning messages. Approximately six hours after the dealer completed Campaign 26-091, multiple braking, stability-control, and driver-assistance warning lights/messages appeared. I returned the vehicle to Ryan Honda. The dealership diagnosed a failed VSA modulator/control unit and initially quoted approximately $1,785 for replacement. Because the failure appeared only hours after Honda performed software work involving interconnected driver-assistance and braking systems, I questioned whether the recall procedure, programming process, electrical conditions during programming, or resulting module communication could have contributed. The matter was escalated to a Honda representative, who reportedly consulted Honda engineering. I was told Honda engineering determined that Campaign 26-091 and the VSA modulator failure were completely unrelated and that the software update could not have caused the failure. Honda subsequently offered to install a used VSA modulator, reducing my cost to approximately $650. I understand that timing alone does not prove causation. However, I believe the extremely close timing between Campaign 26-091 and the sudden appearance of multiple safety-system failures warrants investigation. I am asking the federal safety agency to document this incident and determine whether other Honda vehicles receiving Campaign 26-091 have experienced similar ABS, VSA, brake-system, or Honda Sensing failures shortly after the software update.

Inadvertent Automatic Emergency Braking
On February 21, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE22003) to assess reports of inadvertent activation of the Collision Mitigation Braking System (CMBS), an automatic emergency braking (AEB) system, in model year 2017-2019 Honda CR-V and 2018-2019 Honda Accord vehicles. The reports allege that activation of the AEB system occurs while driving with no apparent obstruction in the vehicle's forward path, resulting in sudden vehicle deceleration. Honda indicated that they were aware of a total of X,XXX reports that may relate to the alleged defect. Honda provided analysis of the alleged defect and alleges that some customers possibly had an inadequate understanding of the CMBS and its limitations.  However, many consumer complaints allege that Honda dealerships were unable to reproduce the condition or state that they were informed that this is considered normal CMBS operation. To date, ODI has received a total of 1,294 consumer complaints of inadvertent activation of CMBS in 2017-2022 Honda CR-V and 2018-2022 Honda Accord vehicles. A total of 31 complaints alleged a crash and 50 alleged an injury. The Total column in the Failure Report Summary removes duplicate reports and shows the total number of reports with unique VINs from all Manufacturer, ODI, and EWR data sources. In some cases, there were multiple reports associated with a particular vehicle in which recurring failures were alleged. In total, there were X,XXX reports, 93 injury incidents and 47 crashes involving vehicles with unique VINs that may relate to the alleged defect. PE22-003 has been upgraded to an Engineering Analysis to further assess the scope, frequency, and potential safety related consequences of the inadvertent AEB activations. The scope has been expanded to include assessment of model year 2020-2022 Honda CR-V and Accord vehicles.

What 2019 Honda Accord owners say
Most recent owner complaints, unedited.
The vehicle keeps going into limp mode and misfire on cylinder 2 and 3 and all dashboard lights are coming on. I had my spark plugs changed and my coils
the warning goes for everything that is on the dashboard. there are no safety features for the car that helps to protect the car and other cars. there are no warnings. this car is dangerous for everyone. no emergency brakes.
I own a 2019 Honda Accord Sport 1.5T. While operating my vehicle, multiple safety-system warnings appeared on the dashboard at the same time. The vehicle displayed “Brake Hold System Problem,” “Adaptive Cruise Control System Problem,” “Collision Mitigation Braking System Problem,” and “Road Departure Mitigation System Problem,” each instructing me to see my dealer. These warnings concerned me because they involved the braking system and several Honda Sensing safety systems simultaneously. I parked the vehicle and turned the engine off. When I restarted the vehicle, all of the warnings had disappeared and the dashboard appeared normal again, even though no repair had been performed. The vehicle has approximately 72,980 miles. I have photographs documenting the warnings while they were displayed. I am reporting this to the federal safety agency because the problem was intermittent and affected multiple braking and driver-assistance systems at the same time. I am concerned that the systems could malfunction again while driving, including the braking/collision-mitigation system. I would like this incident documented as a potential safety defect involving the 2019 Honda Accord.
Car suddenly tries to stop on clear road going freeway speed of 70mph. I'm travelling on the hov lane with few vehicles on the lane to my right. There are no vehicles in front of me.
*brake mitigation system , an yes it is available for inspection. *Car suddenly braked hard on a clear smooth road. Going 45 MPH *No it has not. *No it hasn't. No warning until a big BRAKE lit up on my speedometer
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 the federal safety agency 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.
My check engine light is on along with other light. I am getting the vehicle stability assist system problem, reduced traction and handling. Hill start assist problem vehicle may roll upon brake release, collision mitigation braking system problem, electric power steering system problem. Steering assist reduced, collision mitigation braking system problem. Road departure mitigation system problem. My car when I first start it in the morning idles very hard and then settles. I have taken it to honda and tried to get it covered under the tsb but the lights went off and they claim they could not pull the codes. This has happen several times and my car is under 150,000 miles. This is a safety hazard in traffic when the car decides it wants to stall.
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. the federal safety agency 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.
