Just returned back home from a quick drive and the vehicle was sitting in my driveway. After about 20 min I walked by the car and noticed the entire back window in multiple pieces. There was no one that walked by or drove by. Pieces of glass were noted to be 10 feet behind the vehicle on the driveway. There was no one in the vehicle at the time and nothing in the trunk area that was potentially pressing on the glass. Vehicle was towed to the dealership where it was collision wrapped until the glass could be replaced.

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.

I purchased a 2024 Honda Pilot on [XXX]. In March, between the 4th & 22nd (approx 1800 mi) I thought I saw a crack but as my vehicle had been parked in the parking structure where I live adjacent the ports of LB & LA (prone to excessive dust) & recent rain/moisture causing the dust to form into lines I figured to wait until washing before confirming. On 3/22 I confirmed a crack - no point of impact. As I had planned a vacation to Mexico I opted to photograph the crack AND the vehicle in Mexico capturing date and location stamp. I returned on 4/16. On 4/29 I took my vehicle to El Monte Honda. I let the service advisor know about the crack & upon inspection he found a 2nd crack - no point of impact. The advisor said they were scratches on the inside - 2 piece laminated. I pushed back because the visible thickness of the crack I discovered did not match the hairline feel. He convinced me that replacing the windshield could lead to other issues such as leakage - a known problem on the current generation so I asked him to note the damage - he noted a scratch. I took the vehicle but ultimately decided it wasn't fair as both were in drivers line of sight. Upon return he said the system used to communicate between the dealership and manufacturer was down and would have to come back. I called 2 months later - no return call. 9/13/24 I decide to go to local dealer (Long Beach Honda). The service advisor inspected and said he would call Honda but did not. Driving away I noted a smudge where the advisor located a crack - a 3rd crack, no point of impact. Called Honda & they said no record of me going to the dealer. Closed case. On 10/1 I returned to LB Honda with a record from 4/29 and images. He said possible glass delamination but only because a Boeing engineer reenforced stress cracks. He did not return calls nor advise Honda. Called Honda. They refuse to do anything without a diagnosis and service advisors are running away in what appears a deliberate effort.

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.

When pushing the accelerator there is typically anywhere from a 2 to 5 second delay before the vehicle starts to move. On average the delay is around 2 seconds, but there have been times where trying to pull into traffic the vehicle would not move for approximately 4 to 5 seconds creating a hazard. When the care is moving at higher speeds, the acceleration and gas pedal response is accurate, this only occurs when at a stand still or at very slow speeds. I have taken the car to the dealership to be evaluated and they informed me that the vehicle is operating as it is intended to and the delay is normal. I believe that this acceleration delay is inevitably going to cause an accident because it is difficult to gauge when the care is going to begin moving due to the inconsistent acceleration issue.

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.

PE25017 · 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.

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. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy.

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. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign.
