NHTSA investigations into the engine on the Odyssey

Engine failure. Open.

NHTSA summary
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.

No restart after auto start/stop engages. Open.

NHTSA summary
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 review

Engine failure. Closed aug 20, 2025.

NHTSA summary
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.

Ignition interlock failure - rollaway. Closed jan 14, 2013, led to recall 12V-573.

NHTSA summary
On December 10, 2012, Honda Motor Company submitted a defect information report to NHTSA regarding ignition interlocks in approximately 576,117 model year MY) 2003 through 2004 Honda Pilot and Odyssey vehicles that are the subject of this investigation and 231,044 MY 2003 through 2006 Acura MDX vehicles (Recall No. 12V-573).Honda's report states that a design change to the ignition switch used in the recalled vehicles reduced the range of rotation for the ignition switch from 160 degrees in earlier designs to 125 degrees without a corresponding change to the ignition interlock blocking mechanism.The result was that excessive rotational force could damage a lever that would allow the driver to remove the ignition key that was in a position other than the Park position, which may allow the vehicle to roll away.ODI identified 176 complaints related to the alleged defect, including 48 roll away crashes.Threeof the incidents resulted in the following injuries to pedestrians:1) a broken foot and torn Achilles tendon; 2) a fractured fibula and crush injuries to a shin area; and 3) an incident requiring unspecified treatment at a hospital emergency room.This investigation is closed.The VOQs associated with this investigation are: 10486515, 10486393, 10486100, 10485010, 10482229, 10482091, 10481169, 10481105, 10481079, 10481027, 10480804, 10480648, 10480099, 10480009, 10479934, 10479695, 10479561, 10479517, 10479494, 10479484, 10479437, 10479421, 10479409, 10479343, 10478916, 10478876

What owners wrote

“RE investigation EA25004. We have had two instances of the van failing to restart after it shut off automatically at a red light. This caused a dangerous traffic situation where the van would not start up while traffic was approaching. The battery is in good condition and the van has just over 10,000 miles on it.”

“While waiting at a red light with foot on the brake, the auto idle stop system shuts off the engine but fails to restart it when the foot is lifted off the brake, causing stalling. The vehicle has to be put in park and turned off completely and restarted before it will drive. This has happened twice, once on 5/1/26 and today on 5/7/26.”

Filed May 7, 2026

“The vehicle's Auto Idle Stop system shuts off the engine at stop lights and other low-speed stops and, on multiple occasions, fails to restart, and the AIS disable button is sticking. We disable AIS every single time we drive the vehicle, and on multiple occasions the button has re-engaged itself mid-drive, meaning the safety hazard cannot reliably be avoided even with the workaround Honda recommends.”

“2025 Honda Odyssey has been stalling due to Auto Idle Stop (AIS) failure to restart at traffic lights or stop signs. Engine fails to restart automatically and car needs to be manually restarted with push-button off/on switch. No apparent fix issued by Honda.”

If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
