2022 Honda Odyssey

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.

On October 28, 2025, the Office of Defects Investigations (ODI) opened PE25018 to investigate complaints of inadvertent deployment of the side curtain and/or side thorax air bags. These complaints concern model year (MY) 2018-2022 Honda Odyssey vehicles manufactured by American Honda Motor Co. (Honda). Honda issued recall 26V227 on April 9, 2026, to address concerns of inadvertent side air bag deployment. In the recall filing, the company stated that “[a]s of April 2, 2026, Honda has had 130 warranty claims, 25 reports of an injury, and no reports of death related to this issue from January 24, 2017 – April 2, 2026.” Honda states that the Supplemental Restraint System (SRS) Electronic Control Unit (ECU) contains incorrect deployment parameters for the side thorax and side curtain air bags, which may cause inadvertent deployment when the vehicle encounters strong road impacts, such as driving over potholes, speed bumps, or road debris. Honda stated that the SRS control logic for the second and third rows of seating contained an insufficient deployment threshold margin, allowing signal inputs to be misinterpreted as side impacts and causing inadvertent deployment of the side thorax and side curtain air bags. Recall 26V227 states that dealers will reprogram or replace the SRS ECU with improved air bag deployment parameters. Consumers received notice of this recall in late May 2026. In view of the recall being conducted by Honda, ODI is closing this Preliminary Evaluation (PE). The Agency reserves the right to take additional action if warranted by future circumstances. To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

The contact owns a 2022 Honda Odyssey. The contact stated that while driving over bumps, the vehicle made an abnormal, increasingly loud squeaking sound. The vehicle was taken to a dealer, where the failure was identified as a defective driver’s side rear coil spring that required replacement; however, the part was on backorder. The vehicle was not repaired and remained in the dealer's possession. The manufacturer was notified of the failure, and a case was filed. The failure mileage was approximately 44,000.

The contact owns a 2022 Honda Odyssey. The contact stated that during a State Inspection, the contact was informed that the rear coil springs and shocks were fractured. The vehicle was taken to the dealer, who determined that the rear coil springs and shocks needed to be replaced; however, the parts were on back order. The vehicle was not repaired. The manufacturer was made aware of the failure but declined to provide further assistance because the vehicle had not received the oil change services at the dealer. The failure mileage was approximately 36,800.

While child was seated in the rear right second-row seat of a 2022 Honda Odyssey Touring, the seat belt became stuck and jammed, trapping the child in the car seat. Multiple attempts were made to release the child but the seat belt mechanism would not release. The child became distressed and complained of difficulty breathing. As an emergency measure, the child car seat had to be physically cut and destroyed to free the child. The vehicle was subsequently taken to the dealer. The dealer confirmed that the rear right second-row seat belt was found cut in half and that the seat frame had to be replaced. Dealer stated the belt mechanism tested normal during post-incident inspection but was unable to reproduce the entrapment condition. The seat belt tensioner is suspected of having gotten stuck, causing the entrapment. This is a serious child safety incident involving potential entrapment and breathing distress in the second-row seating area.

I went to open back tailgate with key fob, no sound or anything - tailgate did not open. I tried inside vehicle buttons for back tailgate and would not respond - no sounds or anything. Nothing was obstructing the back gate on the outside or interior of vehicle to prevent it from opening. I found a video of a 2021 Odyssey having water leaks into the car from the sliding door and rusts the power module causing it to short. So, my husband opened the back fuse box and got into the back panel and removed and sure enough there is water damage to the module. It is about $400 to replace and it is only a Honda dealership part. This is a safety issue because there is no way to manually open back tailgate in case of an emergency. If water is slowly leaking and causing corrosion, this needs to be fixed by Honda.

When vehicle was stopped, a loud metallic snap occurred and the back end of the minivan rocked. Van was taken in to get checked and the rear driver spring was broken. Both rear springs and shocks were replaced. Vehicle only has 51,054 miles and mechanics said springs should last much longer. Also, same day that this van was take in for service, the mechanics told me that another 2022 Honda Odyssey had just come in with the exact same problem.

I am reporting a recurring and dangerous failure of the infotainment system and electrical control in my vehicle. The following issues occur intermittently but frequently: Safety Camera Failure: The center display screen often goes black, causing the backup camera and side-view cameras to fail completely. This occurs while the vehicle is in reverse, creating a significant blind-spot hazard and risk of collision. I specifically visited the dealership in early June 2025 to inquire about this issue—and I have video evidence to prove it—yet the electronic fault "magically disappeared" (an intermittent issue) when the vehicle was inspected on-site. Despite this, the dealership still charged me a $300 diagnostic fee. Total System Freeze: The GPS navigation, audio system, and all center console controls frequently stop responding or shut down entirely while driving, causing significant driver distraction. Power Management Defect: Most critically, the infotainment system and audio often fail to shut off even after the engine is turned off and the vehicle is locked. This parasitic draw continues until the 12V battery is completely drained, leaving the vehicle stranded and potentially creating an electrical fire hazard. On 03/20/2026, the infotainment system failed to shut down after the engine was turned off, which completely drained the battery. I had to call AAA for roadside assistance to tow/jump-start the vehicle to the dealership. I have a video recording of the system staying powered on while the vehicle was off. Furthermore, I just replaced the 12V battery with a brand new one in February 2026, confirming that this is a parasitic draw caused by a vehicle defect and not a faulty battery. I am unable to upload videos here, but I reserve the right to present them.
