2021 Honda Insight

On March 7, 2024, the Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE24008) to assess reports of inadvertent activation of the Automatic Emergency Braking (AEB) system in model year 2019-2022 Honda Insight and 2019-2022 Honda Passport vehicles. The complainants allege activation of the AEB system with no apparent obstruction in the vehicle's path, resulting in rapid vehicle deceleration. Honda indicated that it is aware of a total of 412 reports that may relate to the alleged defect. Honda provided analysis of the alleged defect and stated that some customers possibly had an inadequate understanding of the AEB system and its limitations. However, many consumer complaints received by ODI allege that Honda dealerships were unable to reproduce the condition or state that Honda dealerships informed the consumer that this is considered normal AEB operation. To date, ODI has received a total of 106 consumer complaints of inadvertent activation of AEB in the subject vehicles.In total, ODI reviewed 475 reports involving vehicles with unique VINs that may relate to the alleged defect. Of the reports reviewed by ODI, three (3) allege a crash caused by the inadvertent activation of AEB and two (2) allege injury. This Engineering Analysis is being opened to further assess the scope, frequency, and potential safety related consequences of the inadvertent AEB activations. Further, the scope of the investigation is being expanded to include assessment of model year 2023 Honda Passport vehicles. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

The contact's daughter owns a 2021 Honda Insight. The contact stated that while her daughter was driving at an undisclosed speed, the front driver's and passenger-side air bags suddenly deployed without impact. There was no warning light illuminated. The contact stated that the air bags cracked the front windshield and injured the driver's arm. The police arrived at the scene, but no police report was filed. The contact was unsure whether the driver had received medical attention. The contact's daughter had someone drive the vehicle to the residence. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 150,000.

There is a massive hood flutter when large vehicle drive towards me going above 50mph. It feels and looks like the hood is not latched correctly and going to open into my windshield. This has happened since I purchase the vehicle new in 2021

Went in for a typical servicing. They noted that the downstream O2 sensor was damaged by rodents. The vehicle, with around 14k has always been stored in a weather tight garage, never stored outside. There has been no rodents in the building since I owned it from 1999. This is a presumptuous statement I refuted, but they wouldn’t take off, and I felt this is a warranty or recall item. There are lots of speed bumps in the North Portland neighborhood, which may have caused the problem by cable scraping. I believe they documented it as rodents to escape their extended warranty contract requirements. I purchased an O2 sensor, which my independent said I don’t need to use it after taping the scrape as there’s no electronic issues being reported in the system. I would like this investigated and them pay for the sensor I apparently don’t need to install.

I received a 2021 Insight Seat Weight Sensor Safety Recall in September 2025 saying that recall replacement parts were now available at Honda Dealers. Ever since I received this notice, none of the Atlanta area Honda dealers are able to remedy the defect in my vehicle due to lack of parts, contrary to the notice saying parts are available.

Under certain circumstances, the portion of the PCU that controls charging of the 12 volt accessory battery malfunctions, sending the PCU into a "fail safe" mode, preventing battery charging and activating warning displays for the driver. This has caused my vehicle to stall while driving, potentially increasing the risk of a crash. Other honda hybrids during this year have been recalled but not by my VIN number, however I am having the exact same issue. Below has me give a specific date but this happens almost every morning.

The brake servo control unit feel simulator which reduces the simulation force provided to the brake pedal during emergency or failed conditions and is a key component of realizing a Regenerative Braking System. It provides a good pedal feeling to a driver, improves energy recovery and ensures braking security. My safety has been put at risk as that part is integral to my brake system (including the hybrid function) e.g. my car was in reverse and the brakes were not responding and had to leave my car. I towed my car to a local independent service provider and they confirmed via the OBD-II scanner that confirmed my break servo control feel simulator is bad and would need to be replaced. After doing research, the brake servo part is made in Japan by a company called Nissin. The part has been recalled in Japan and UK due to failures in similar hybrid models. The brake servo serves many functions including ensures consistency, mimics traditional braking, and provide the driver with a natural-feeling brake pedal, especially because the system relies on both regenerative braking and hydraulic friction brakes. For about 3 days I received a cluster of warning signs from my car such as traction control, brake system, brake, steering malfunction, and ACC. Given that this part directly affects braking capability and overall vehicle safety, I am deeply concerned that my safety has been compromised as the life of the part is supposed to last the life of the car (about 150,000 miles) . I respectfully request an immediate investigation, and would like to know whether this issue is covered under an existing or pending recall campaign. If not, I'd like to submit this to the recall campaign in the U.S. Please advise on the next steps for inspection, replacement, and ensuring my vehicle is safe to drive. Thank you.

While my wife was driving my car on a busy road. The servo brake control unit/ pedal simulator broke making it near impossible to stop the car. She had to crash the car into a parking block. And Honda import/export is uncooperative and dismissive of the fact that my wife and daughters lives were jeopardized due to the part malfunctioning

On two (2) occasions, the "collision mitigation braking system" braked with no reason. It has happened on a quiet and straight line residential street with no other moving vehicle, pedestrian, animal, or any other obstruction in view. After one second or so of braking, it returned to normal. It is available for inspection. I have not spoken to the local Honda dealer about it, and there were no adverser repercussions. There were no prior warnings of any system malfunction.

Service Bulletin - The ACC system error message comes on while driving when outside temperatures are low/near freezing due to snow and ice getting stuck to the front of the millimeter wave radar. This can cause DTC P2583-76 (Temporary stop of Integrated Driver Support System [Misalignment Millimeter Wave Radar]) to be stored.

Service News - If an Adaptive Cruise Control System Problem comes back on when the vehicle is driven in freezing conditions, inform the customer it is likely due to snow or ice buildup on the radar. Advise the customer of the following procedure to clean the front grille where the radar is located.
