2019 Honda Accord

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.

On July 2021 my fuel pump motor was replaced due to a recall . My car has a raw smell of gas coming from my back seat . I took it to the dealer on 10-24-26 they wanted to charge me 200 to check it which I thought it was crazy due to they had replaced the motor on the fuel pump and I asked to talk to manager he said it was replaced on 2021 and it’s not covered no more . I think if it was replaced maybe the motor or parts that they used where defective. They should check with out charging me

The contact owns a 2019 Honda Accord. The contact stated that while driving at an undisclosed speed, the “Service Engine” warning light illuminated and the vehicle was hesitating and shaking abnormally. The contact used a diagnostic scanner to retrieve DTC for engine misfire in cylinders #2 and #3. The manufacturer was notified of the failure. The vehicle was taken to a dealer where it was diagnosed with coolant intrusion into the cylinders caused by the cylinder head gasket failure. The vehicle was repaired. The failure mileage was 77,689.

Fuel injectors went totally bad at 93,000 miles on a car that has been VERY well taken care of and serviced several times a year. daily driver, no speeding or stunting or anything like that. Got into car and fuel injectors went bad and couldnt accelarate at all, all of the sudden. couldve been VERY dangerous. this is a larger issue and there SHOULD BE A RECALL. heard about this problem, extremely disappointed.

Air conditioning failure: The A/C was blowing warm air on the first day of ownership. • Cooling system failure: The vehicle subsequently experienced overheating issues and left me stranded. • Coolant loss and radiator leak: All Star Honda identified a leaking radiator and found the cooling system out of coolant. • Failed thermostat: A failed thermostat was identified during the diagnostic and repair process. • Stop-leak substance found in the cooling system: Stop-leak material was observed in the cooling system. I have concerns about why it was present and not disclosed initially • Water pump and cooling-system repairs: Repairs included work on the thermostat and water pump, followed by radiator replacement and a coolant flush. • Continued overheating concerns: Despite repairs, I continued experiencing overheating alerts. • Engine performance problems: The vehicle experienced a loss of power, with a reported inability to maintain speeds above approximately 60 mph during one incident. • Check-engine warning: A prior repair-order history documented a blinking malfunction indicator light during a driving incident. • Diagnostic trouble codes: Codes P2601 and P272D were subsequently reported. • Potential head-gasket concerns: The possibility of a head-gasket problem has been raised during the ongoing dispute. Honda has referenced a multi-model cylinder-head-gasket warranty extension, but I have not received approval for coverage on my vehicle. • Warranty denial: Honda corporate has declined to approve the requested warranty coverage. Despite the repeated problems, diagnostic visits, and repair attempts, I am still dealing with the consequences of purchasing a vehicle that has not provided the reliable transportation I paid for. I have spent time and money trying to get answers, and I have been left facing the financial burden of a vehicle that I cannot confidently depend on. I am sharing this timeline because consumers deserve trans

The response to an accelerator input on this vehicle is unreasonably slow and has many times resulted in an unsafe condition. When applying a significant amount of throttle from a stop, or a slow speed, the driver expects the vehicle to respond immediately. I would like to note, that I am not referring to the vehicle's rate of acceleration. I am referring to how long it takes for the vehicle to begin accelerating. During several controlled tests, I applied significant throttle and timed the response to nearly 3s before the vehicle began to exhibit any significant acceleration. I believe this can be easily corrected as it is likely a delay built into the software.

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 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 NHTSA 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.
