Per Honda, the standard maintenance of replacing a timing belt and tensioner has put more tension on the crankshaft, which causes a tapping noise from the connecting rod bearings when the vehicle is accelerating under load. The vehicle is available for inspection upon request. Honda has said that this does not harm the engine, but a noise of this kind is not normal and any noise of this kind associated with this particular part of the engine has the possibility of degrading the engine's life and causing a potential safety issue while driving down the road. Yes, the problem has been reproduced by the dealer. Dealer service department has been the only one to inspect it. No, there were no warning lamps, messages, or other symptoms of the problem prior to the failure. The issue first appeared right after getting the mandatory timing belt maintenance when driving away from the dealer service department.

Hi, I have a 2020 Honda Pilot that showed signs of stalling. AutoNation Honda Thornton Road checked (03/07/2026) and reported I need an INJECTOR KIT replaced and SDC GDI -INTAKE THROTTLE BODY FURL INJECTOR SERVICE. All warning lights were on intermittently (on all day then nothing for 2-3 days then on all day the following day.) The vehicle vibrates and feels like it's loosing power. Honda's website stated risk as " If the fuel pump module is inoperative, the engine may not start or can stall while driving, increasing the risk of a crash or injury. " I have two small kids (18 month and 5 year old) that I commute to and from school every day. Honda's website shows the same issue for Honda Pilots 2016-2021 however, my VIN does not qualify me for the recall. Instead I received an estimate for said repairs for $3,345.06. Please! I am asking you to intervein as it is unfair to single out some vehicle owner even though they are having the same issue as others. Thanks in advance.

Driving on the highway dash goes completely black. Can’t see speed. Cruise control shuts down. Have to pull off the highway shut the engine down and wait for a couple minutes then restart. I have had all recalls repaired at the dealership where purchased but this happens weekly. At 50,000 miles I noticed rough and abrupt transmission shifting and clunking with a lag in acceleration. This continues despite multiple transmission flushes. The problem continues to worsen and current mileage is at 71000

2020 Honda pilot will sporadically turn off at highway speeds and at stop lights and will not turn back on until placed in park with foot on the brake. This is not to be confused with the start/stop feature used to save fuel. Additionally the 2020 pilot will lurch forward (like stuck in drive) while still in park.

There was a snap like sound under my hood while driving. Shortly after, the check engine light engaged and the vehicle lost all ability to accelerate. This happened while merging onto a fairly busy road, with rolling hills. If there were vehicles around there would have been potential for an accident. If this happened on the freeway in a middle lane, the vehicle would not have been able to successfully exit without causing extreme danger to the passengers and other vehicles. The vehicle stopped on the side of the road. When the ignition was briefly reengaged, there were rolling error codes, including vehicle stability, all wheel drive failure, etc. The engine was noticeably knocking. The vehicle was towed and inspected by an independent mechanic. The 3rd cylinder in the engine will no longer hold compression. I now need to get the vehicle to an engine specialist for further inspection and repair.

4PE25008 · Engine Failure
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.

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.
