There's a grinding and clicking noise when turning the wheel left and right in a parked position and when slowing down. The dealership replaced the steering rack once already 1 year ago. Now the grinding and clicking noise is back and alot worse. The dealership is going to replace the steering rack for a second time. Spoke to Honda mechanics and told them that there must be another underlining issue.
Steering makes clicking and creaking noise after vehicle is warmed up and driving slow, like parking. Took it to Mcgraft Honda and service adviser heard the noise. Dealership then informed me that the tech could not duplicate the noise and told me it’s normal to hear noises while turning.
Strange clicking noise during low speed steering left or right and moving steering wheel while parked. Honda dealer states they are unable to replicate issue. Issue is very unusual for a new vehicle. Multiple people have same issues on forums and Facebook groups. This is a potential safety issue if there is a faulty electrical s…

Strange clicking noise during low speed steering left or right and moving steering wheel while parked. Honda dealer states they are unable to replicate issue. Issue is very unusual for a new vehicle. Multiple people have same issues on forums and Facebook groups. This is a potential safety issue if there is a faulty electrical steering gear box or suspension component. Honda needs to take responsibility and fix this issue instead of saying they can’t replicate it or that it maybe normal. I took video it is a sound that is audible inside and out.

I hope this message finds you well. I am writing to express my deep concern regarding the ongoing safety issues with my leased Honda, which I obtained in March 2024. Shortly after leasing the vehicle, I noticed that the sensors would frequently activate and deactivate without any apparent reason. In May 2024, while driving, all the sensors turned on, deactivating all safety features and causing the car to swerve. The sensor lights remained on the next day, prompting me to take the car to the dealership. I was informed that the sensor and a camera required repairs, which were subsequently addressed. Despite my concerns about the safety of driving this car, especially with three children, I was assured that the issue was resolved. I filed a complaint with Honda Corporate, and they indicated that the issue would need to recur 2-3 times before considering a different vehicle. Unfortunately, on [XXX], all the sensors activated again while I was driving, causing the car to stop accelerating in the middle of a busy road with my children in the back seat. This placed us in a life-threatening situation, as other vehicles were traveling at high speeds. The transmission light also turned on, advising to avoid high speeds. The next morning, I reported the issue to Honda and arranged for roadside assistance to tow the car to the dealership. During the towing process, the sensors activated again, and the car struggled to accelerate. Once at the dealership, I provided videos of the car's behavior to Ricardo, the service advisor, who acknowledged the severity of the issue. However, he later informed me that the sensors were not currently active, and the scanner could not detect any issues. Despite keeping the car overnight for further testing, they were unable to identify or repair the problem. I was advised to either pick up the car or leave it with them, but no loaner vehicle was offered. I am extremely concerned about the safety of driving this car. I pay 685 monthly INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO

Sudden collision warning displayed on dashboard and brakes were automatically applied. No vehicles in front of me and vehicle behind was sufficient distance away. There was no collision situation at all. Brake system light, collision warning light, and collision mitigation braking system problem - See your dealer displayed on dashboard. I pulled into parking a parking lot, stopped, and turned engine off. After restarting engine, error seemed to clear. Dealer review is pending.
Several crunching noises and knocking noises when moving the steering wheel at low speeds.
Today, the same problem with my car reemerged immediately after I collected it from the dealership, where it was supposedly repaired for this issue.

Today, the same problem with my car reemerged immediately after I collected it from the dealership, where it was supposedly repaired for this issue. Upon driving away, making three stops, and using both the Brake Hold and Engine Idle-Stop features, I encountered the same malfunction, leading to the flashing of all warning indicators. Alarmingly, the parking brake engaged on its own at traffic signals, and the car wouldn't turn off even when this issue was occurring. Previously, I had provided the dealership with a detailed description and photos of this issue. They identified the cause as an improperly installed rear wheel speed sensor, which they claimed to have fixed and reset the error codes. However, the problem persisted right after I retrieved the car. I immediately returned the vehicle to the dealership. The car was still not turning off, and while they noted the issue, I am skeptical about their technical ability to diagnose and solve the problem effectively. I urge Honda to promptly address this issue in collaboration with the dealership and to initiate recalls to prevent potential severe accidents. To replicate the issue, toggle both the Brake Hold and Engine Idle-Stop features in various combination, and drive at a speed of 35-40 mph with 4-5 stops of around 30 seconds each toggle combination. When the issue reproduces, All the warning messages will illuminate, and the parking brake will engage automatically. I suspect the drive controller getting reset due to some electrical tripping when brake hold and/or engine-idle stop is toggled which is causing a cascade of failures.
I bought my 2024 Honda Pilot two weeks ago, it only has 300 miles and suddenly all the warnings indicating system failures were activated, engine check, lane assist, emergency braking, emission system, etc., it almost didn't start, it left me in road.

2PE25017 · Inaccurate Rear Passenger Seat Belt Warning Status
Opened Oct 28, 2025 · No close date supplied
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.

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.
