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.

SUV check engine light for the emissions system came on 11/21/2025. The light does not stay on all the time, it goes on and off ever several days. During my state inspection, dealer diagnosed issue to a P0430 code and ran a cylinder AF test. It revealed that cylinders 2, 5 and 6 failed for rich conditions and stated the fuel injectors require replacement. Both the dealer and honda Corp. stated there is no coverage for this issue. I did find that this issue was found with previous years for my model and make, however my year is not covered for the warrenty extension. Honda service bulletin 20 - 100.

My car has always had slight issue getting consistent fuel pressure causing the engine to rev abnormally when giving gas during acceleration. On 11/25, my car failed to start due to the fuel pressure being too low. I brought my car into two mechanics including a Honda certified dealership to inspect an issue with my fuel pump. I was informed that other Honda Pilots of the same year as mine have a recall on their fuel pump, but my VIN was not included. Both mechanics indicated that this is the exact issue that the other Pilots under the recall have and they were not sure why mine was not included. It is pulling the same codes, too, when it went under diagnostic testing as issue with the lower fuel pump.
The auto shut off has been not working properly and the vehicle wont restart after it shuts off. My wife was at a traffic light, and the vehicle shut off.

The auto shut off has been not working properly and the vehicle wont restart after it shuts off. My wife was at a traffic light, and the vehicle shut off. When the light turned green, it did not restart. As a result of this she about got taken out by a semi that was coming in behind her. This could have been a deadly accident as it is raining and wet. She was stuck at the light on a busy highway for 3 minutes before the vehicle would restart.
My car was fine. I was driving fine and then I pulled out of my neighborhood and all of a sudden my check engine light started blinking and my car was hesitating and jumping. I pulled over for 10 minutes with the car turned off and then it was fine. It did something similar once before a week prior but I thought it was a one t…

My car was fine. I was driving fine and then I pulled out of my neighborhood and all of a sudden my check engine light started blinking and my car was hesitating and jumping. I pulled over for 10 minutes with the car turned off and then it was fine. It did something similar once before a week prior but I thought it was a one time thing. There are recalls for fuel injectors on the year prior honda pilots. And the mechanic shop said that’s what they would replace when they looked at it.

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.
EA25004 · No Restart After Auto Start/stop Engages

Status: open (inferred from source dates) · Engine And Engine Cooling:engine; Engine And Engine Cooling:engine:crank/camshaft Position Sensor; Engine And Engine Cooling:engine:engine Control Module (ecu/ecm):software; Engine And Engine Cooling:engine:hard Parts Internal/mechanical
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. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

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.
