2016 Honda Pilot

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.  To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

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 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.

American Honda Motor Co. Inc. and dealership (Della Honda - Plattsburgh, NY) refused to perform the required alignment as part of recall campaign 26V365 without out-of-pocket payment. As part of the recall, they removed and replaced lower trailing arms and installed subframe bracing. The service advisor said alignment was part of the recall. However, after the work was complete and I drove away from the dealership, the steering wheel was noticeably pulling to the left. I brought it back immediately and they said they had not performed the alignment as it was not part of the covered recall. They charged me for the alignment stating they thought the steering pulling was from my recent strut replacement, not the rear subframe replacement. Alignment after this type of subframe work should be standard practice and part of the covered expenses for the recall.

I have an unresolved rear sub frame recall. The dealer looked at the problem. Said to fix it that control arms need to be replaced. Along with any other parts to fix recall. They submitted to Honda for goodwill claim to cover control arms. Honda approved it, and dealer told by Honda don’t know when parts be in. That was about six weeks ago. Still no updates from Honda to dealer on fixing it or parts being in.

very well maintained 2016 honda pilot oil changes done on time only 149k miles started it up labor day weekend to a sound of engine knock. It ran for a min or two before I turn it off oil was full. It is not the failed timing the belt tenisoner.... I called my local Honda dealership where they said my vin was not included in the crank/engine bearing recall. I have no warranty and the dealership of course wants me to tow it there to pay their tech their diagnostic fee. I have read so many stories of this happening to the honda pilot and Ridgeline vehicles. This is a shame.... Honda needs to step up & double check their manufacturer dates & add more vin to this recall ASAP

Engine warning light came on, then all warning lights came on, then the engine just stopped. Honda dealer confirmed it was due to a failed crankshaft and might be covered under a current recall, 23V-751. We spent over $10,000 in diagnostics, purchasing a rebuilt engine and installing the rebuilt engine. The issue was confirmed by a Honda Dealer. No issues with the Pilot prior to this happening. There are many complaints for the same issues from other 2016 Honda Pilot owners with the same failures. Honda knows this was an issue with parts used but has only covered part of 2016 Honda Pilots instead of all of them.

My vehicle's fuel injectors failed, triggering a check engine light with code P0430. This matches a known manufacturing defect described in Honda's Technical Service Bulletin 20-100, which states injectors on affected vehicles may not have been manufactured to proper specifications, causing internal wear or clogging. The problem was confirmed and repaired by an authorized Honda dealership. The manufacturer extended the warranty for this defect to 10 years from original purchase or 150,000 miles, whichever comes first, due to the scope of the issue. My vehicle fell outside that window by approximately 15,000 miles despite showing the identical, factory-acknowledged defect. I paid out of pocket for a repair the manufacturer's own documentation attributes to a manufacturing defect, not normal wear. I am filing this complaint because owners with vehicles exhibiting this same documented defect are being denied coverage based on an arbitrary mileage/date cutoff, even though the defect originates in manufacturing and symptoms (a triggered check engine light) may not appear until after that cutoff has passed. This means the extension does not protect all owners of vehicles containing the defective part, only those whose symptoms surface within an arbitrary window. There was no impact to vehicle control or immediate safety when symptoms appeared, but the underlying condition stems from a part Honda has already documented as defective.

The 6-speed automatic transmission on my 2016 Honda Pilot EX-L (103,200 miles) has experienced a severe mechanical failure casing dangerously hard, violent gear shifts during both acceleration and deceleration. Critically, no dashboard warning lights or malfunction indicator lamps illuminated while this dangerous driving condition persisted, leaving me with no advance warning of a safety hazard. A subsequent diagnostic scan at an Authorized Honda dealership revealed hidden diagnostic trouble code P0776 (pressure control solenoid "B" performance or stuck off) and a failing torque converted. The severe, unpredictable jerking and hesitation during shifting creates an immediate traffic hazard during acceleration in traffic. Approximately 45 days prior, an out-of-town Honda dealership performed a prescribed triple fluid flush when the issue first arose. Then, 5 days later, my local Honda dealership performed the prescribed software update for shifting issues, which failed to remedy the underlying defect again. The dealership has now quoted $11,000 + for a full replacement of the transmission and torque converted. American Honda corporate has opened Case Number: 16606142 to track this defect.

Service Bulletin - Under certain circumstances, after coming to a stop and engaging idle stop, the vehicle may not restart automatically due to excessive cylinder pressure and/or low cranking torque. Typically, the customer can immediately restart the vehicle by selecting Park and pressing the ENGINE START/STOP button.

Service Bulletin - The AWD warning light is on potentially due to water intrusion into the rear differential pump motor connector area that corrodes the terminals.

Service Bulletin - Drivers may experience a chirping sound coming from the engine area with the engine warmed up due to the high pressure fuel pump is making a chirp.

Service Bulletin - MIL flashes and vehicle will not accelerate, low power. After cycling the ignition, the symptom does not return with no stored DTCs. This issue is more common in regions with cold weather (specifically near or below freezing temperatures). Usually after a long drive (around 2 hours) and accelerating while cornering.

Service Bulletin - The MIL flashes and vehicle will not accelerate, low power. After cycling the ignition, the symptom does not return with no stored DTCs. This issue is more common in regions with cold weather (specifically near or below freezing temperatures). Usually after a long drive (around 2 hours) and accelerating while cornering. Moisture accumulation in the intake manifold during long drives gets drawn into the combustion chamber while cornering, causing misfires.

Service Bulletin - The A/C does not blow cold air, and the lower corner of the condenser around the receiver/dryer cap is stained due to a poor O-ring compression against the receiver/dryer barrel wall.
