On March 18th, 2023 at 6:30 PM I parked my car and waited for the curbside pick up at a cafe with my 3 girls 6 (my niece) 7, (daughter), and 11 (daughter) years old. The car started blinking all the lights started accelerating by themselves and turned off immediately. while I tried to turn it on it never started instead it blinked and displayed many messages, including transmission system problem, emission system problem, etc. I thought the battery died and called my husband to jump-start the car and it took 30 minutes to get driving with all these scary movements. my kids were traumatized by the experience and I thought thank god they were safe and the problem is solved. After almost a week once again on March 27th at I'm driving the kids to Karate and driving back at 5:45 PM all of sudden it started blinking, shanking, grinding noise, loud noise, and many messages, transmission system problems, emission system problems, etc. "D" drive started blinking. smoke came and I was still on the road not sure what to do. I thought I will be hit by the other cars behind me. luckily I was almost close to our street and it made a loud noise and I parked the car. it still blinked and smoked heavily and I turned off and got out of the car. It was a very scary movement of my life. I have 2 kids and I drive them every day for their day-2 day school/activities. I cannot believe I bought a new car in 2017 trusting the brand and it is already failed, my family. The car has to be towed to the dealership the dealer gave me a code P-2652. I want Honda to take care of their mechanical issues. I cannot get over the trauma I went through and I'm still shaking while I'm writing this. My 7 year old do not want to talk about the car which made me very sad. My girls loved the family car and now I'm in tears thinking about their safety. I want NHTSA to safeguard the consumers who go through these issues. HONDA PLEASE WAKE UP. My girls are ready to draft a letter to HONDA and NHTSA.

I have a 2017 Honda Pilot EX-L with a mileage of 41010 miles. I have completed all the recommended services in a timely manner by an authorized Honda Dealer. When I was driving the vehicle yesterday (3/25/2023) at a speed of around 65 mph, I got an error message saying "Transmission System Problem". There was no error code associated with it. There was no problem in the driving. But at the end of the drive, in the parking lot when I had to reverse, the backup camera will not turn on. After parking the vehicle and turning off the vehicle and restarting it, the error message went away. And then the backup camera also started to work fine. When I was driving back home, the error message came on again when the speed reached around 65 mph. I came home and searched about this error message and I came across a lot of complaints of the same nature for 2017 Honda Pilot owners. Please refer to the discussions on the following links as samples: https://is.gd/RB78A1 , https://is.gd/a84e9h . Since many owners are experiencing this, I am wondering if this is a manufacturing issue. Many owners are talking about the Dealerships asking them to replace Transmission which costs around $8000 or to replace Transmission torque converter which will cost $5000. As of now my vehicle drives fine but I got exactly the same message twice at the speed of about 65 mph. I am scared to take this vehicle on to highways since my vehicle is following exactly the same pattern as that of other owners of 2017 Honda Pilot. I also saw Honda Ridgeline owners in the same year also having similar experience online. All of this make me think that this is more of a design/manufacturing problem impacting many owners and hence may be NHTSA would want to look in to this.

Car has failed to restart numerous times after coming to a complete stop, typically at a traffic signal leaving me stranded in the middle of the road with cars whizzing by in adjoining lanes and cars behind me beeping. This creates a very great hazard. This has happened at least a dozen times. To restart the vehicle, I have to put the vehicle into park, put my foot on the brake, and press the start engine button. This issue started in 2019. Another issue is that periodically the dash display will rotate through every possible malfunction indicator. When this happens, each malfunction indicator light stays on the screen for a couple of seconds and moves onto the next one. When this is happening, the vehicle will not go any faster than 15-20 mph which I think is a safety mechanism to make sure the engine is not further damages if an actual issue is occurring. Fortunately, this has only happened on neighborhood streets where the speed limit is 35 mph so the sudden loss of power did not create an immediate hazard. This issue started in 2019. I took the vehicle to a Honda dealership regarding both these issues but they were unable to determine what caused these issues even after I showed them the video I took of the dash display rotating between all of the malfunction indicators. No police, insurance representatives, police or others have inspected the vehicle.

Vehicle's start/stop system continuously failing. Vehicle will "stop" or shut off at intersection as intended, but then fails to restart, leaving my family stranded in the middle of traffic. This obviously creates a very dangerous situation for my family. This has happened several times. When you try to restart the vehicle it acts as if it doesn't have the power to do so. Inspections of the vehicle at the dealer continuously show the battery is in the "green" or great working condition. Although they've said this, their only response to the issue so far is to replace the seemingly fine battery.

Was unable to restart the car again after many retries. I was very concerned that another vehicle would hit me since we were at a very busy intersection. All the electronic warnings on the dash appeared to flicker on and off when trying to restart. Eventually had to have the vehicle towed to the Honda dealer since the vehicle could not be jump started or restart on it's own.

I took ny Honda Pilot in for a routine oil change. I have had issues with a squeaky sound coming from under the hood. The dealership said my transmission fluid had broken down, and they had to flush/replace it. It cost me over $350. Honda said it wasn’t covered under warranty as it is a maintenance issue. I only have a little over 57,000 miles on it. The squeaky sound persisted, so they replaced a belt. I had to take it back a week after, because yup sound is still there. It was in the garage for over 2 weeks and I just got it back yesterday. I’m not sure exactly what they did, only know they had to take the undercarriage off to get to it. I never received the paperwork as the case hasn’t been closed by the repairman yet. I have an appointment Thursday February 16th to go over wheel bearing issues now and am supposed to get the paperwork for this last repair then. Very frustrating.

I am reporting 2 safety issues in this report, both involving the AUTO STOP/START function in my car. SAFETY ISSUE #1: MALFUNCTIONING AUTO STOP/START (ASS) FUNCTION: At least 4 times during the past 2 months, I have had a serious safety issue with my 2017 Honda Pilot wherein it stalls and is completely inoperable for a short time, while I’m stopped at an intersection. This has caused me undue stress and jeopardized the safety of myself and my passengers, and disrupted traffic. According to my best recollection, the situation occurs when the ASS function stalls the engine (when stopped), and I manually press the ‘Disable ASS’ button to restart the engine. But instead of the engine turning back, all systems completely ‘black out’ as I frantically try to re-start the engine, to no effect. After several scary seconds, somehow it re-starts. SAFETY ISSUE #2: CORRECTLY FUNCTIONING ASS FUNCTION: Even when functioning correctly, the ASS function has caused a safety issue for me at least twice. When the ASS function was automatically engaged, I was unable to immediately accelerate to avoid a potential collision. Although no collision resulted, these few scares ‘trained me’ to manually disengage the ASS function whenever I remember to do so. Based on my experiences, It would be safest to have no ASS function at all.

Car alarm keeps going off randomly and the electronic dashboard flickers repeatedly while the car is parked. I recently left the car at a parking garage and apparently the alarm was triggered and ran all day - I came back to the car that evening and there was clicking sound coming from the engine (not turned on, of course). The battery was drained and when I got a jump start, the alarm went off and the dashboard went crazy again. I wonder what would might happen when the car is being driven. There's clearly something wrong with the electronics. The dealer said I needed a new body control module (BCM), but the part is hard to come by apparently. Having done some research on the the issue, this appears to be a common problem with Honda Pilots. My car only has 50k miles on it and seems out of character to have this part fail. The short-term solution is to leave the car unlocked which in turn disarms the car alarm, but I've seen the dashboard and cabin lights flicker off and on in this state. This problem has been ongoing for months now.

PE25008 · 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. 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.
