2019 Honda Accord: false forward collision warnings

Filed Oct 9, 2026 · Fuel system · LA

I am reporting repeated, unpredictable loss of engine power and propulsion in my 2019 Honda Accord Touring 2.0T (approximately 146,000 miles). The exact cause remains UNKNOWN. On XXX, while driving on [XXX] near [XXX], my vehicle suddenly lost acceleration at highway speeds and eventually stalled. The vehicle repeatedly lost power, experienced crank-no-start conditions, and at one point could barely maintain 10 mph. I was stranded and had to have the vehicle transported to a Honda dealership in [XXX]. Diagnostic code P0087 (Fuel Rail/System Pressure Too Low) was recorded multiple times, including at 70–74 mph. Numerous warnings appeared, including emissions, brake system, electric power steering, stability assist, adaptive cruise control, collision mitigation, and road departure mitigation. The unpredictable loss of propulsion creates a serious collision risk, especially on highways and in traffic. The Honda dealership initially could not reproduce the failure. After replacing the spark plugs at my expense, the vehicle was returned to me. Approximately 23 miles later, the malfunction returned, and I immediately brought the vehicle back without clearing any codes. Honda subsequently diagnosed and replaced the high-pressure fuel pump at my expense, but the loss-of-power issue continued. The vehicle previously received Honda’s in-tank fuel pump safety recall repair in May 2025. Despite that recall remedy and subsequent repairs, the vehicle continues to malfunction. The exact cause remains undetermined. The vehicle has been inspected by an authorized Honda dealership. Repair records and diagnostic information are available, and the vehicle can be made available for inspection upon request. I am requesting an investigation into this recurring safety-related loss of propulsion. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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. 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.

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.

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

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.
