There’s currently a recall on the 2018 2019 Honda odysseys. The recall is for the same as exact issue that I had with my 2018 Honda Odyssey there’s a problem with the connecting rod bearings recall campaign number 23V751000. I’m being told from Honda that my van does not fall into the production date range for the recall. I’m being told that any repairs I’m going to have to cover myself even though it’s the same issue that the other vehicles are having. I was on the interstate traveling about 70 miles an hour. My check engine light came on blinking I lost total power I had to get out of the left lane and make it all the way to the shoulder between traffic. I had my car towed to the Honda dealership that I’ve taken it to for every single service since I purchased the vehicle. I want to know why my vehicle is not gonna be covered under this so-called recall, if it’s having the same as exact issues as the other vehicles and the recall. And Honda is refusing any help

Around October 29th my vehicle developed a faint to loud noise within 24 hours. There was no engine light, no leaking of fluids and no other warning.

Around October 29th my vehicle developed a faint to loud noise within 24 hours. There was no engine light, no leaking of fluids and no other warning. As we drove the vehicle to a repair shop I could tell there was some hesitation or lack of normal power. The shop we took my vehicle too was not able to do any repair or diagnosis so it was towed to Honda of Olathe, then New Concept Auto and finally Sallas Auto. On November 10th, I was told my engine needed to be replaced due to bearing issue. The mechanic ran diagnostic tests and did not find any past cleared codes or active codes that should have been triggered by an engine issue. My vehicle was serviced regularly. Most recent was an oil change end July/Early August, no issues were found, no metal flakes. In that short period of time my engine failed and I had to replace with a used 2018 engine. During this time we were informed by friends of the Honda Odyssey recall for 2018 engines, however upon calling Honda Corporate, I was told my specific 2018 Honda Odyssey was not included and would "not be covered at this time, if ever". My mechanic is adamant the issues listed in the recall document is the exact issue I had with my engine. On attachment please notice item 1 and 2. Also the deer note at the top of the attached invoice is determined to be a coincidence by three separate mechanics - Honda of Olathe, Sallas and New Concept Auto as well as the State Farm advisor. Thank you

For the last 3 months the car will turn on by itself and drain the battery. Went to several mechanics that could not find a reason for this issue. This weekend, while I was driving on the road, the car stopped while driving on the highway. This happened 4 times risking my life, wife, and my children. The problem has been reproduced and confirmed by other owners of this car on various forums. I have not had the vehicle inspected by the manufacturer as they are trying to charged me thousands of dollars to review the issue. There were no warning lamps or signals on the car.

This vehicle has had numerous electrical issues, culminating in the need for three batteries in a six year. Period. From day one there were electrical issues with the auto stop start and the car in one occasion the battery completely died. Honda was unable to identify the issue and electrical issues. Continue to happen. in the last 18 months I’ve had numerous occasions where this auto stop start would engage at a stoplight stop sign in the middle of busy traffic, but would not start back up. I took it in for service and they cannot re-create or identify the issue. This is very scary when it happens as I have been on start and go traffic on the interstate on busy intersections and the car will not move nor can it be restarted for 5 to 10 minutes. Honda offers no solution to this dangerous problem. After months of not being able to fix this. Identify a problem the car no longer moves into reverse consistently Honda recommends new transmission. After becoming frustrated with Honda and feeling unsafe with my family in this vehicle, I had to trade it in for a new vehicle as no solutions were offered to make me feel safe driving it or to get it repaired effectively or identify why it keeps needing new batteries and has electrical dysfunction since purchase

4PE25018 · Inadvertent Deployment Of Side Air Bags
Opened Oct 28, 2025 · Closed Jun 25, 2026
Status: closed (inferred from source dates) · Air Bags; Air Bags:sensor:side Impact; Air Bags:side/window
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.

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.

PE25008 · Engine Failure
Opened Aug 20, 2025 · No close date supplied
Status: open (inferred from source dates) · Engine
The Office of Defects Investigation (ODI) has received 414 reports of connecting rod bearing failures in the 3.5L V6 engine used in the following vehicles: Model Years (MY) 2018-2020 Acura TLX, MY2016-2020 Acura MDX, MY2016-2020 Honda Pilot, MY2018-2020 Honda Odyssey, and MY2017-2019 Honda Ridgeline. The subject engine failures were analyzed as part of a Recall Query (RQ24013). It was determined that these engine failures are outside the scope of Honda Recall 23V-751. Further, evidence gathered in conjunction with RQ24013 does not suggest this failure is caused by the same crankshaft manufacturing defect that is addressed by Honda in Recall 23V-751. Based on analysis of data from RQ24013, NHTSA has closed that investigation. The significant number of reports of engine failure in vehicles outside the scope of RQ24013 presents a potential safety risk that warrants further investigation. ODI is opening this Preliminary Evaluation (PE) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues.

RQ24013 · Engine Failure
Opened Nov 8, 2024 · Closed Aug 20, 2025
Status: closed (inferred from source dates) · Engine
On November 8, 2024, the Office of Defects Investigation (ODI) opened Recall Query RQ24013 to assess the scope of Honda recall 23V-751 after receiving complaints that alleged connecting rod bearing failures in vehicles that were not within the scope of recall 23V-751. In November 2023, Honda recalled 248,999 various Model Year (MY)2016–2020 Honda and Acura vehicles equipped with the 3.5L V6 engine. Honda recalled these vehicles due to a crankshaft manufacturing defect that caused premature connecting rod bearing wear and engine seizure. While the out-of-scope failures involved in these complaints appear to have a very similar failure mechanism as the recalled engines, a thorough analysis of all available data from Honda has not indicated that the same manufacturing defect exists in the out-of-scope engines as the engines recalled by 23V-751. Based on this analysis ODI has determined that Honda has properly defined the scope of recall 23V-751. Consequently, ODI will close this RQ investigation. NHTSA will continue to investigate these complaints of engine failure as part of a new Preliminary Evaluation Investigation (PE25008). The Agency reserves the right to take additional action if warranted by new circumstances.
