After previously reporting that a connecting rod bearing noise developed after the timing belt maintenance package was performed near 100,000 miles, the connecting rod bearings failed around 3,000 miles later while going down the interstate with children in the car. Thankfully the Pilot, which was shaking and making noise, was able to be pulled over to side of the interstate and later towed to the dealer service. No symptoms other than the noise at low speeds usually from take off, which regional Honda said wouldn’t damage anything, but apparently it did.

Engine failure
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, the federal safety agency 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
PE25008
No Restart After Auto Start/Stop Engages
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.the federal safety agency 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.

Engine failure
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)2016â2020 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. the federal safety agency 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.

What 2020 Honda Pilot owners say
Most recent owner complaints, unedited.
Tachometer is starting to surging idle. Getting a wave of errors lights and messages. It’s also a known problem on the 2019 of the same model and it has a recall. I received the same code from an auto repair shop. Service Bulletin 21-010
The contact owns a 2020 Honda Pilot. The contact stated that after starting the vehicle, there was an abnormal ticking sound coming from the engine. The vehicle was taken to the local dealer, who examined the engine and discovered metal shavings inside the oil pan and there was engine rod bearing damage. The contact was informed that the engine needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was provided. The contact was informed of the federal safety agency Action Number: PE25008 (ENGINE). The contact stated that the vehicle had experienced the failure listed in the federal safety agency Action Number. The failure mileage was 46,500.
Engine start/stop function fails to restart after automatically shutting off at a light or in traffic. It falters and fails to start, then the dashboard lights up with errors, and I have to put it into park before restarting. Sometimes it takes a few tries before restarting. The battery has been replaced twice in the last year and the starter motor within the last year too, but the issue persists.
When the vehicle is at a stoplight or stop sign, the engine regularly shuts off. The engine does not automatically restart and sometimes it takes several minutes to restart the engine, leaving the car blocking traffic at a light. This happens REPEATEDLY and often.
The problem on our Honda Pilot is related to the starter. We have had four instances now where the auto start/stop function has failed to restart the car after sitting at a stop light. This has happened at very busy intersections resulting in difficulty restarting the car and the car temporarily disabling the auto start/stop functions. I just had this happen for the fourth time on 7/9/26 at approximatlely 6:00 PM. I am planning on taking it into the dealership to have it looked at since it has happened multiple times. I also see on the Internet that other owners are having this issue and the federal safety agency is looking into it. I feel this is a significant safety issues since this happens in traffic and could result in people being rear-ended when their car won't start. This problem started for me about two months ago but I thought it was just a fluke but apparently it is not. The battery and electrical system has been checked and are working properly.
Engine Auto off/ on when stopped for signal light. Routinely, when stopped at a light, the engine will fail to turn back on and the car will go off but will not turn itself completely off. This leads to a delay for the engine clicks into neutral and in order to restart, I must turn the vehicle completely off and then restart. This issue occurs when I release the brake to begin my acceleration after the light turns green. And the vehicle stalls so that the traffic behind me which was prepared to move forward is stuck. The amount of time it takes to get the vehicle turned completely off and back on generally takes much of the light change time.
The contact owns a 2020 Honda Pilot. The contact stated that while driving at various speeds, the check engine warning light illuminated. The vehicle was taken to a local dealer, where it was diagnosed with failures of 4 of the 6 fuel injectors. The vehicle was repaired. The contact related the failure to an unknown recall; however, the VIN was not under recall. The manufacturer was made aware of the failure. The failure mileage was approximately 99,000.
The issue that I am having is very serious if I forget to hit the off button which disables the energy saving my car will shut off. This happens if I am at a stop sign or stop light. I literally have to restart my car all over again. Cars behind me have almost hit me. At first I thought this is a new vehicle it is normal for this happen but quickly rode cards similar to my vehicle features and their cars would not stop like mine does. I have called the dealer several times to report this incident but the managers never return my phone calls. I do fear my safety and my children's safety.
If I leave the auto idle engine stop on,and come to a complete stop, the auto engine stop turns on, but as I release the brake to drive, the vehicle stalls in drive and engine shuts down. I will have to manually turn the car back on and restart the whole system before being allowed to continue. All while at a green light and a ton of traffic waiting behind me to move! Its very disappointing and embarrassing. The failure happened about 5 days after purchase. I just assumed it was a bug, and always turn it off before starting my drive.
