2021 Honda Pilot fuel system problems

Filed Nov 8, 2026 · Electrical, Engine · NC

2021 Honda Pilot EX-L, 3.5L V6. The engine cranks slowly and is sluggish to start when restarted after a short stop of roughly 10-30 minutes (for example, running errands). After the vehicle sits an hour or more, it starts normally. The condition appears tied to engine heat-soak. The battery has been tested and ruled out as the cause. This is a repeat of a prior problem. The vehicle previously received Honda's repair for the idle stop no-restart condition under Service Bulletins A23-010/23-009, including starter assembly and starter relay replacement and a valve adjustment. The slow hot-restart symptom has returned since that repair. This matches the condition under the federal safety agency investigation EA25004, where owners report the problem returning after the campaign repairs. Safety risk: Slow or failed restarts when the engine is warm could leave the vehicle and occupants stranded, including in traffic or unsafe locations. With Auto Idle Stop, a weak restart could also cause the engine to fail to restart at an intersection. Dealer: Scott Clark Honda performed the work the first time. I have an appointment with Hendrick Honda for Tuesday 11/10 Warning lamps or messages: None The vehicle is available for inspection on request. Video of the slow crank can be made at any point as it’s every time I drive.

The electrical for the infotainment system cuts out and the rear camera is no longer on the screen, it will cause loud popping while driving as the MOST Net system is failing. There is also poor gas mileage and reads the gas tank contents incorrectly while displaying incorrect MPG typical with the fuel pump recall for this generation of Honda Pilot, but both of these recalls removed my specific year shortly after they were announced.

While driving with my family in my 2021 Pilot on the interstate at 75mph, I felt a shudder while in traffic. Fortunately, I signaled to get over and cars around me responded, because the check engine light flashed on and off and the car shut off. We had enough time to roll to the side of the interstate safely because drivers around me were aware and considerate. The car would not restart so we had to tow it. The Pilot has been evaluated by an independent mechanic who says that a failure in the high pressure fuel pump caused oil to dilute gasoline. A full engine replacement is required. There was no prior warning of this issue. American Honda has been contacted for potential support. Early stage of that, but dealing with them has, so far, been great.

My current 2021 Honda Pilot (purchased used May 2024) is stalling out in live traffic - the most recent on XXX creating a massive safety hazard. (In addition, the engine is making the same exact clicking noise that the 2015 Honda VIN:[XXX] made right before the engine catastrophically seized on my way to work. That 2015 Honda Pilot seized due to a defective Variable Cynlinder Management (VCM) system. This defect was covered by a court-ordered federal class-action settlement warranty extension (Alex [XXX] v. American Honda, Case No. XXX), extending coverage to 10 years/150,000 miles. While that vehicle was fully within this window - Honda of [XXX] wrongfully denied this legal warranty.) The CURRENT 2021 Honda Pilot (Purchased Used) VIN: [XXX] suffers from intermittent engine stalling in live traffic. The dealership has failed to resolve this issue across three separate visits, while exploiting the emergencies. The timeline of failed repairs includes: 2/14/25: The vehicle stalled in live traffic. The dealership charged me $420.48 for diagnostics and a failed repair. 8/13/25: The dashboard lit up and the vehicle suffered engine failure leaving my family stranded for 9 hours waiting for Honda Assist. It was brought to the Honda of New Rochelle service center where they exploited this emergency to charge me an exorbitant $1,300.00 out of pocket for unrelated work financed via Sunbit loan. 9/24/2025: The vehicle stalled in live traffic for a third time. The dealership charged me an additional $572.00 for another failed repair. They reguse to give me the RO's and the car has 29 active codes including U3006-16 (ECU Power Source Failure), proving a severe electrical or fuel delivery hazard remains completely unresolved.

My vehicle has failed to restart several times with the auto idle start feature enabled while stopped at a stoplight. I was in a turning lane the first time it happened, so other vehicles had to make a left hand turn from a lane that was meant to go straight to get around me. The starter has not been inspected There weren't warning lamps prior to the auto start feature not working. When the car would not turn back on. I had to put the car in park, turn off "Accesory mode", turn the car back on, and put the car back in drive. There have been several other instances the car has hesitated to restart, but it does.

After driving the vehicle for a few hours during a very cold day, as we got off an exit ramp. We then turned onto the next road in our travels and the check engine light went off and blinked. The vehicle went into limp mode. Pulled the vehicle over, turn the car off and then back on and everything worked just fine. Had an oil change already scheduled for 2 days later. Brought the vehicle in for it oil change and we told the Honda Mechanic (dealership) what just happened. His response was: That is a common honda problem. "You did what we would have told you to do. Turn the car off and then back on. When the engine compartment gets really warm when driving for long periods of time with the cold weather, something tells it to misfire and throws a check engine code. We tell people to do what you did and turn the car off and then back on". Meanwhile we had to go out of town again the following weekend. As soon as we got near our destination the same thing happened again. This time in an intersection! Thankfully nobody was coming at the time of the limp mode to avoid a potential serious accident. I have put a lot of research into this and there are a lot of forums online that state this issue with no solution by Honda. I do not see how that is safe to have your car randomly throw a code and be forced to pull over immediately.

I believe I have a fuel pump issue. My car has stalled on multiple occasions while trying to pull out of my driveway. There is at least a quarter tank of gas. I have had to get gas in a gas can and add it to the tank and then it would start. I now make sure I always have at least a half a tank of gas. On three separate occasions when the auto idle stop turns the car off at a light, the car does not restart when the brake is released and it slips the car into neutral (very dangerous at an intersection) There was a recall on Pilots Fuel system, gasoline: Delivery: Fuel pump Recall date 2023-12-17 Recall no. 23V858000 Honda (American Honda Motor Co.) is recalling certain 2013-2023 Honda Accord, Civic Coupe, Civic Sedan, Civic Hatchback, Civic Type R, CR-V, HR-V, Ridgeline, Odyssey, Acura ILX, MDX, MDX Hybrid, RDX, RLX, TLX, 2019-2022 Honda Insight, Passport, 2020 Honda CR-V Hybrid, 2018-2019 Honda Clarity PHEV, Fit, and 2015-2020 Honda Accord Hybrid, Pilot, Acura NSX vehicles.

We were driving our 2019 Honda Pilot and at a traffic light the car failed to restart after the auto stop-start system shut off the engine. This happened when I started to step on the gas so we could have been rear-ended by the car behind us. The brakes also appeared stuck when I tried to depress them so I could restart the car. There was no warning until the car refused to start, but the computer system did appear to do some sort of a reboot sequence.

My Honda Pilot experiences a serious safety issue with the Auto Idle Stop feature. When the system engages at a stop (such as a red light), the vehicle sometimes fails to restart, leaving me stalled in traffic. This creates a dangerous situation for myself and other drivers. The problem appears to be related to the Auto Idle Stop system and/or the auxiliary battery. Many other Honda owners are reporting similar issues, which suggests this may be a widespread defect that needs investigation. I just dropped the car at Honda dealership for further inspection

On the afternoon of Friday, August 29, 2025 while driving the Honda Pilot on a US Highway, the "Check Engine" light came on and the vehicle immediately experience a decrease in speed. Top speed on the highway suddenly became approximately 25 MPH and the Pilot became sluggish and was shaking. We had to drive with the vehicle's "flashing hazard lights" on due to the low speed on the 55 MPH highway speeds. Multiple alerts appeared on the vehicle information display panel. I was just able to get the vehicle home. Due to the Labor Day Holiday, we were not able to get the vehicle scheduled to go into the shop until the Tuesday following the Monday Labor Day holiday. It was very difficult to get the Pilot to start on the Monday "Labor Day" to drive to the automobile shop for them to look at it the next morning (Tuesday, September 02, 2025). Once it did start, it again displayed multiple alerts on the vehicle information display panel behind the steering wheel. Speed was again limited to a maximum of 25 MPH. While driving to the shop (less than 5 miles away), the engine stopped completely and the car shifted out of the "Drive" mode and switched into Neutral without any action of the driver to do so. We had to coast into a nearby parking lot to get the vehicle out of the active city road. All attempts to restart the vehicle in the lot failed. We had to call for a tow truck with a flat bed to take the AWD Pilot to the local shop. While in the shop the codes were diagnosed by the attached "Full Diagnostic Report" via "TOPDON". The shop owner called us saying that the fuel pump had failed and that there was an active the federal safety agency recall for this issue with Pilots. We called the local Honda Service Department and they stated that our VIN number was outside of the current recall for the same Fuel Pump issue. We feel that the VIN coverage for the already Active Recall for the Honda Pilots should be expanded to include our VIN for the same reasons as the Active Recall.
