The vehicle came to a complete stop while attempting to enter the Highway. As I accelerated to gain speed, and the vehicle halted down to stop, all sensor warning systems started to light up on the dashboard: Adaptive Cruise Control, Automatic Emergency braking, Lane Departure Warning, Parking Collision Warning, Lane Keeping Assistance -- all sensors flashing simultaneously. As our vehicle stopped, the vehicles around us in the Highway had to abruptly stopped as well, causing a serious hazard, not only to myself and my family, but also the potential for a serious injury to other as well. This incident happened to us twice, and my passenger was able to record a video of the dashboard, as all the sensors were flashing and the vehicle switch to neutral on its own coming to a stop. We explained to the Honda dealership service department and after the second time, they kept the vehicle for service and it has been over (30) days since we had any update. The vehicle has been inspected by the dealership, and it is still there as parts are in back order, but there are not sure of what the real problem is. There were no previous warnings of this problem, the vehicle is a 2024 Honda Pilot Elite with 30,174 miles, and still under dealer warranty. This is the 3rd Honda Pilot I ever owned and never experienced anything like this before. My biggest concern is that if they do not fix this vehicle properly or if it is defective, my life and my family's will be in danger every time we drive it, as we do not know when it will decide to stop while driving.

Incident Description: While traveling at 45 mph with Adaptive Cruise Control (ACC) active, the vehicle experienced a "phantom braking" event triggered by high-contrast shadows on the roadway. The Collision Mitigation Braking System (CMBS) incorrectly identified a shadow as a physical obstacle and abruptly applied the brakes in a clear path of travel. I was forced to manually override the system by applying the accelerator to prevent a potential rear-end collision. Safety Risk & Technical Context: This defect is repeatable under specific lighting conditions and occurs across multiple speed intervals (35–45 mph). I believe this incident is directly related to the ongoing NHTSA Engineering Analysis (EA24002) regarding inadvertent AEB activations. Furthermore, recent Service Bulletins (such as MC-11024251-0001) regarding Front View Camera and Radar Sensor updates suggest a known failure in the system's ability to process high-contrast environmental data. Conclusion: My local dealership failed to investigate the complaint. The sudden, unexpected deceleration poses a severe safety risk to the vehicle's occupants and following traffic. I request that NHTSA formally notify Honda of America regarding this recurring ADAS failure to ensure that my VIN is prioritized for the necessary sensor alignment and software enhancements.

The contact owns a 2024 Honda Pilot. The contact stated that while driving approximately 75 MPH, the brakes inadvertently activated after passing a truck on the highway. The contact stated that the vehicle unexpectedly slowed down to 40 MPH. The contact stated that there was no warning light illuminated. The contact stated that while the accelerator pedal was depressed, there was an abnormal banging sound coming from under the floorboard. The contact pulled over and checked the vehicle, and saw a puddle of transmission fluid on the ground. The vehicle was towed to a dealer where it was diagnosed, and determined that the transmission needed to be replaced. The vehicle was not yet repaired. The contact stated that the inadvertent braking had occurred once before, but it was not as severe, and the vehicle was not diagnosed. During the first failure, there was no warning light illuminated. The manufacturer was not informed of the failure. The failure mileage was approximately 20,000.

My Honda is having strange, intermittent issues with a plethora of things. I have taken it to a diagnostic specialist who worked with a phone mechanic and noone can tell me what is going on. My car will fully shut off at stop lights randomly, so I have to turn off the auto-idle feature every time I drive. Sometimes my power steering cuts out and my wheel locks and unlocks and my computer screen shuts off when this happens. I have to shut off and start my car for it to work again. Other times, all of my automated safety features stop and I get a huge slew of messages telling me that my lane assist, automatic hill braking, and a ton of other automatic safety features don't work. My car can't lane assist, do adaptive cruise control, use the backup camera, or anything. It goes away if I stop and restart my car a bunch. I also had a seatbelt alarm that was going off repeatedly with no reason. The dealership turned off the alarm. I am having a lot of issues with this car that makes me question if it is a lemon. I see other new Pilot owners mentioning issues with power steering shutting off and it's a huge safety risk. Noone knows whats wrong or how to fix it so what do I do? This happens intermittently, randomly, and recurrently since June.

It brought the car to an abrupt stop for no reason. If a car had been behind me, they would have slammed into me. It was so abrupt, I felt like I had whiplash. It was terrifying. I had taken the car into the dealership to due to the brake pin recall just 3 days ago. They inspected and said the pin was fine. When I called them to report this experience, they said it was unrelated to the recall. I am bringing my car into them tomorrow to inspect what happened with the automatic braking system.

The automatic emergency braking system in my vehicle has repeatedly activated without any visible reason. The brakes engage suddenly even when there are no cars, curves, reflective surfaces, or obstacles nearby. This has occurred on straight, empty roads and in clear conditions. We have previously taken the car to the dealership for issues related to sensors and wiring, and were even told at one point to turn off certain safety features. Most recently, we went through the dealership and escalated the issue to Honda corporate, but they closed our case and claimed there is nothing wrong with the car. I am very concerned that this unresolved issue could lead to the brakes locking up in a dangerous situation, potentially causing an accident.

I believe that there is a safety issue with the design of the adaptive cruise control on the 2024 Honda Pilot. The vehicle applies the brakes at about 1 mph over the selected speed. It is especially aggressive when topping a hill. The gas lets up, but due to the vehicle inertia, the car slightly accelerates, then braking. I believe that this action is unsafe for several reasons. It slows the vehicle several mph below the set speed causing cars behind me to swerve or come close to me. No human driver would apply the brakes in that situation. It also appears to irritate those same drivers. I’m glad that none of them has a weapon so far. It also applies the brakes going downhill on the interstate highway. This occurs at any speed below 55 mph. This also makes it look like the driver is continually tapping the brakes, when no one normally would. I suspect that there may be extra brake wear. My family asks what is going on with the car because of the aggressive braking. I previously owned a 2018 Honda Pilot with adaptive cruise control. It used transmission downshifting to slow the vehicle. I admit that there were some over speeds, but nothing serious. The 2024 Owner’s Manual states that downshifting is also used, but I’ve only seen the brakes used for over speed control. There are no user selectable adjustments to the system. I am getting used to this (feature, not a bug) by clicking off the cruise control whenever the conditions are close for a brake activation. This causes me to pay more attention to monitoring for those conditions, rather than the actual driving and traffic scan. I suggest that the system use downshifting followed by brakes after a 3 or 4 mph excursion from the set speed.

Flashing warnings include AWD system problem, electric parking brake problem, brake system problem, brake hold system problem, electric power steering problem, antilock brake system problem, vehicle stability assist problem, hill start assist problem, trailer stability assist problem, hill descent control system problem, adaptive cruise control problem, lane keep assist problem, collision mitigation system problem, road departure mitigation system problem, low speed braking problem, auto high beam problem, parking sensor problem, antilock brake system problem, as well as drive mode change unavailable, rear hatch will not open, drivers seat will not automatically move into position once vehicle is started, vehicle will not shut off without having to hit the off button numerous times, and vehicle is not auto shutting off after the 10-15 min timeframe. Dealer states they have ordered the part and is currently on back order. Was told Honda does not provide loaner vehicles for warranty work. Seems strange that a wheel sensor could cause so many errors and shut off all safety features, brakes and drivetrain of the vehicle.

Status: open (inferred from source dates) · Seat Belts; Seat Belts:rear/other; Seat Belts:status Indicator Switch
The Office of Defects Investigation (ODI) has received 6 complaints, and multiple Early Warning Reporting (EWR) field reports alleging inaccurate rear seat belt warning status. These allegations concern both false positive and false negative statuses in model year (MY) 2023-2024 Honda Pilot vehicles manufactured by American Honda Motor Co. (Honda). The complaints state that the rear passenger seat belt warning system is displaying inaccurate information to the driver for both second and third row seating positions. This can lead to the driver dismissing warnings regarding rear seat belt status. The inaccurate information can also cause the driver to believe rear occupants are buckled when they are not. This reliance on false information presents concerns for the safety of children and child seats located in the rear rows, especially in the third row where the buckled status is more difficult for the driver to visually confirm. ODI is opening this Preliminary Evaluation (PE) to determine the scope and severity of the potential problem and to fully assess the potential safety-related issues. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data.

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement.
