Our 2016 Honda Pilot Elite sputtered as we tried to accelerate and then the engine died. It is available for inspection upon request. The engine stop unexpectedly while driving limiting control of the vehicle. The problem has been reproduced for an independent service center. The Honda service center, and two independent service centers are unable to determine the cause from the vehicle codes. There were no warning lamps, messages or symptoms prior to the engine dying.

To whom it may concern, My name is [XXX] . I hope this message finds you well. I am writing this message with a heavy heart, to advise of our story that is ending with a tragic experience. On [XXX] my wife, [XXX] , and I, walked in a Honda dealership. We drove away confident about our new vehicle, a 2016 Honda Pilot. It was highly recommended by the salesman. Since then, we have maintained the vehicles services. Sadly, on Saturday, [XXX], the vehicle malfunctioned and engine stalled on the highway. The steering wheel locked, the vehicle would not accelerate, and the brakes failed. I managed to pull over, but we were terrified and stranded for over forty minutes. The vehicle was towed home, and we contacted the dealership, who agreed to inspect it. It was taken to the service center in early December and has remained there since. The certified Honda mechanics' diagnostic report confirms issues consistent with online Honda recalls. As this is our only vehicle, this situation has created significant hardship for our family. Our dream of owning a Honda has unfortunately turned into a nightmare. Honda corporate has denied our request for any and all assistance. We would be most grateful for any assistance you can provide.

We have always taken great care of our Pilot, regular oil changes, tire rotations, checking the fluid levels. Just before we went on vacation, our Pilot's check engine light came on and started blinking under normal driving conditions. When we hooked up the code reader, it was for a misfire in the second cylinder. Having changed the spark plugs about 30-40k before this incident, we tested the plugs and assumed it was the coil. We changed the coil. After returning from vacation, we drove the car minimally yet after about 40-50 miles, the code returned with knocking sound. We had the car towed to our residence...to find the same code. We inspected the plug and coil, no issues were present and the code was cleared. The next day, the code came back on and the engine was knocking very loud and had definite performance issues. I checked the Honda recall page and our car had no open recalls. I noticed that other Pilots with the V6 engine in our model year range were included an investigation by the NHTSA. Our mechanic drove our pilot for 30 feet and immediately called me to tell me that he would not suggest even spending money on diagnosing the problem....as he believes the engine is a total loss. It seems unfair that Honda would not address this issue as it seems a wide spread problem after a simple google search.
We were just told that the engine rod bearing on our 2016 Honda Pilot is going out. I see that the 2018 and other years have had recalls on this issue. I have read on different forums that owners of the 2016 are also having this problem. Can the 2016 please be included in the recall? Thank you, [XXX] and [XXX] [XXX] [XXX] …

Wife was driving kids to school on the highway when the vehicle bucked repeatedly and started making a loud ticking noise. When checked using a scan tool, it showed that a backfire had occurred on cylinder 5. Vehicle only has 120,850 miles on it and has always been serviced as required at a Honda dealership. There were no previous warnings or indicator lamps to foreshadow the engine problems with the vehicle. Vehicle was taken to the Honda dealership and they stated that it needed a new engine. When asked as to why, they stated they just knew it did. After researching the problem online, the connecting rod bearing recall for 2016 Honda Pilots was found. The symptoms were exactly the same as what others had when having that same failure. Vehicle taken to another repair shop who came to the same conclusion that the vehicle needed a new engine. Honda of America was contacted about the issue and they stated that the vehicle was not covered under the recall as it is outside the stated manufacturing window even though the engine is having exactly the same connecting rod failure as is stated in the recall. Honda refused to provide any assistance or help in resolving the problem. The dealership wants over $10,000 to install a USED replacement engine. Honda is obviously misrepresenting the problem to limit their liability even though they are fully aware there is a bigger problem with these engines. Quite a few other people online in groups/boards are stating they have the same engine failure and Honda is refusing to take accountability for it. Fortunately, it did not fully throw a rod at highway speeds with my wife and children in the vehicle as a much more life threatening situation may have occurred. We have little confidence if they replace the engine with a used, lower mileage engine that this situation that this issue will not reoccur.
I was driving down the highway when I started to hear a knocking sound at certain RPM. No check engine light and I was unable to safely pull over. As I continued driving looking for a safe place to park the vehicle, within a few minutes the noise in the engine got worse and then suddenly the vehicle completely lost power and wou…

I was driving down the highway when I started to hear a knocking sound at certain RPM. No check engine light and I was unable to safely pull over. As I continued driving looking for a safe place to park the vehicle, within a few minutes the noise in the engine got worse and then suddenly the vehicle completely lost power and would only drive in limp mode. Luckily I was able to pull off to an offramp and get the vehicle into a gas station parking lot. I called for a tow truck and had the vehicle towed to the nearest dealership. At the dealership they inspected the vehicle and found that it was damaged similar to the Safety recall related to NHTSA Action Number: RQ24013 and advised me to have it towed Calgary Honda. I called the Honda Dealership and they informed me that it did not qualify for the recall at the time but the issue sounded familiar. I had them and the current dealership quote me the pricing and decided that I would proceed with the repair from Honda directly. It took awhile to get a replacement engine in and I had to wait several weeks but I was finally able to have it replaced at Calgary Honda in November of 2024. It cost me $10,000 to replace the engine as well as have the work done to repair the alignment after the power failure and replace the battery due to the vehicle sitting for weeks in the cold. I believe my vehicle is part of the same issues as: NHTSA Action Number: RQ24013 and wanted to submit my report to hopefully get reimbursed by Honda for the engine and all other costs associated with the Recall
Unknown, I was driving on the Highway when all of a sudden my car came to a stop with the engine smoking up. I had it tow to my house and had my brother in law who is a car mechanic come check and he states that it is the connecting rod bearing. We see recalls on it for other same car model and year, but not for my VIN.

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. 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 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.

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.
