The fuel injection system routinely fails or misfires. Not only does this cause an issue with said system but it also triggers a host of other dashboard alerts. The alerts display all wheel drive problem, emission system problem, power steering problem, hill start problem, vehicle stability assist problem. This is a safety issue because the amount of alerts especially unrelated alerts is obfuscating any actual problems and making it difficult to diagnose the real issue. Investigation shows many other drivers having the same issues with this model only going away when the fuel injection system is replaced. It's also safety issue because if the fuel injection is failing then the car may shut off at a danger to the driver and the public. Given that it is known and chronic it should be a recall

In my 2016 Honda pilot a lot of buttons are popping up on the screen with no information about how to fix it. My car is having trouble accelerating and is hesitating when needing to accelerate. I was unable to speed up while driving to get to 45 mph Because it would not speed up. All the buttons that are coming up on my car or not correct it’s showing trailer issues and I’ve never once trailed anything with my car. It seems like it’s having extra trouble when the air condition is on as well. I’m unable to figure out what is wrong with my car because all the buttons are not coming up correct when they plug it in for a diagnostic. I have had the alternator replaced and that did not change anything.

My battery was being drained until dead by a faulty keyless control module. I paid to have the battery replaced after my son and I got stranded 1.5 hours from home. All the lights on the dash went off and nearly every error code displayed as well. Currently at Honda dealership getting the module replaced at a mere $840 after I paid $370 for battery installation when my car "broke down". Now to see I am not the only Honda customer with this issue in this model of vehicle. The car started displaying all the error codes about a week before it began just completely draining the battery that was on 6/23. Battery replaced that day and by Saturday 6/28 was unable to start my car due to battery being completely dead. Had to jump my car and take to dealership on sunday 6/29. So was late to work and have been without my vehicle for over a week while they were trouble shooting the issue.

Car sound system distort and no sound after 10 minutes of driving. No bluetooth audio, radio, music working. Changing volume, sound setting, factory reset the info system but the problem still exist. Increase the A/C fan speed and driving through pumps seems make the problem start earlier. Sometimes, turn off the car and restart the car after 30 minutes, the sound system is back on, but after the 10-15 minutes the sound went off again. This problem could cause safety issue as I relied on navigation sound while driving. There seems to be the same problem that being recalled in newer model.

The alarm continuously goes off unprompted while the car is off. The dashboard lights will flash as if the car is attempting to start without any input from the driver. Clicking can be heard from the dashboard during this time. The battery is drained from this continuous issue. Other systems then seem to be impacted. The car has begun lurching out struggling to shift gears. In the last 3 years, all fluid systems have been flushed, battery replaced, oil gauge replaced, and keyless remote entry module replaced. The issue persists. All recalls have been completed as well. When the car is in ACC mode, the battery indicator is on and the flashing of the dashboard indicators still happens (as when the car is off right leading up to the alarm being tripped). Once the car is started , the indicator goes away. There is no apparent clicking or changes in the dashboard when the car is on and actively drawing from the battery.

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.

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.
