Vehicle began to misfire on cylinder 3. As the issue continued more cylinders stared to misfire. Next was number 6, then 2 increased up the engine. Air fuel ratio was 1.6. Assuming it was fuel/air/electrical in nature, the spark plugs, and fuel injector were changed and air intake and upper valves were cleaned of carbon build up. All gaskets replaced by new. Discovered and replaced a bad egr valve. Last codes that the car displayed before towing to dealer were many misfire codes and 2 engine/transmission communication errors. Dealer shop discovered air fuel ratio of 1.35 and checked all work before. Discovered fuel pooling and some shiny areas in the engine from scoping it. Decided that if was a bad engine with internal failure and transmission. Quoted me $17000 (about the same value as the vehicle if it was jn very good condition) for a new engine and transmission or $6800 for a used engine alone at risk of replacing transmission as well assuming communication errors do not go way or transmission fails further. I have called honda corporate my reference # 16624114. I requested goodwill repair due to recalls and class action lawsuits related to connecting rods in engines of similar cars and model years. And transmissions recalls for similar cars and model years. Goodwill is unlikely but pending.

When I am sitting at a traffic light and the auto engine idle stop gauges it very frequently completely shuts off the engine and will not restart. I will hit the power button to try and turn the vehicle back on, but it won’t work. I have to put the car into park, completely turn off the car battery, open the car door, while sitting in the middle of traffic, and then shut the car door and restart the car. If I do not open the car door, I cannot restart the car. I have taken this into Honda twice to have an evaluated and they “cannot find“ the problem despite their being a bulletin out specifically about this problem. It is now shutting off on me three and four times in a single trip. I was almost in an accident trying to restart my car when a light turned green and I couldn’t get my vehicle to restart as all the cars around me went. This has been an ongoing problem for years.

I'm filing a formal safety complaint regarding my 2019 Honda Odyssey, VIN [XXX], & requesting an engineering-level review by American Honda. I've brought this vehicle to an authorized Honda dealer numerous times for recurring & increasingly serious electrical, engine/power-loss, & transmission problems. Despite thousands of dollars in repairs, the problems continue. The vehicle has unexpectedly shut off/lost power; the power sliding doors have failed & required manual opening; low-battery warnings have appeared; & the radio/infotainment system repeatedly loses power and resets. I have photographs showing the message: “Anti Theft System–This system has lost power.” More seriously, the vehicle has malfunctioned in Park, Reverse, while shifting into Drive, & while turning. Most recently, the transmission would not engage properly and the vehicle had to be shut off and restarted multiple times before it would go into Drive. Delray Honda documented this transmission failure/no-drive incident on its August 2026 repair order. In May 2026, I brought the vehicle to Delray Honda for a Check Engine Management System warning. Repairs were performed, but the warning returned within days. Delray Honda then replaced the power distribution module, costing me approximately $2,000. I've spent thousands more dollars addressing these recurring problems without resolution. I understand Honda/NHTSA Recall 19V-299 involved certain 2018–2019 Odysseys and a loss of power to the Transmission Control Unit. My Odyssey appears to have been manufactured around the time of those Hondas that were covered by that recall. I'm not claiming without diagnosis that the defect is identical, but the similarity of the symptoms warrants an urgent investigation. I request that Honda open a formal safety case, review my complete service history, DTCs and TCM/PCM data, determine whether my vehicle has the same or a related defect, and review my prior repair costs for reimbursement. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

Hello, my 2019 Odyssey 3.5L V6 engine has a severe knocking noise/engine failure identical to Recall 23V-751, but my VIN was excluded. The car has only 81,100 miles and started the knocking out of no where a week ago. I had an independant mechanic take a look at it and he said the same thing that it was the connecting rod bearing and the knock was coming from the engine. I dont think it is fair that I should be held liable for an engine repair that is a factory fault and just becuase my vin number is not inlcuded. The vehicles oil was also just changed at the dealership prior to the knock starting. Please have this strongly considered to have HONDA cover this repair.

The connecting rod bearings failed, resulting in engine damage. The failed bearings, crankshaft, and oil pan debris have been retained and are available for inspection on request. The vehicle developed a loud ticking noise from the engine. A Honda dealer initially diagnosed the noise as coming from the timing belt tensioner and replaced the timing belt and tensioner. The noise was unchanged after that repair. The dealer then traced the noise to the bottom end of the engine and performed a teardown on 07/16/2026, which confirmed connecting rod bearing failure with significant metallic debris throughout the oil pan. The dealer documented the failure with photographs. The engine is not driveable. The problem has therefore been confirmed by an authorized dealer through disassembly. The manufacturer has been notified but has not physically inspected the engine. There has been no police or insurance involvement. Warning symptoms: an audible ticking noise from the engine was the only symptom. No warning lamps, dashboard messages, or other indications appeared at any point before or during the failure. Safety: this failure mode is the subject of NHTSA Preliminary Evaluation PE25008, opened 08/20/2025, covering connecting rod bearing failures leading to complete engine failure in the 3.5L V6, including MY2018-2020 Odyssey. It is also the failure mode described in Recall 23V-751, which states that engine failure may cause loss of motive power and increase the risk of crash and fire. My vehicle falls outside that recall's build range and the manufacturer has declined coverage on that basis. Had the bearing seized while driving rather than being found during shop diagnosis, the engine could have lost power or stalled without warning. This vehicle carries family passengers on highways. No crash, fire, or injury occurred.

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.

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.
