2017 Honda Pilot complaints

Alarm randomly goes off when parked and locked without doors being open. Unplugged hood latch sensor and it stopped but security system is not armed (absence of blinking light).

The contact owns a 2017 Honda Pilot. The contact stated that while driving at an undisclosed speed, the vehicle failed to accelerate while depressing the accelerator pedal. There were several unknown warning lights illuminated. The contact referenced NHTSA Campaign Number: 23V858000 (FUEL SYSTEM, GASOLINE); however, the VIN was not included in the recall. The dealer was not notified of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 143,000.

My Pilot only had 46,942 miles when it failed due to a camshaft thrust cover surface roughness being out of spec causing excessive camshaft movement. This was confirmed by the mechanic at Honda that worked on my Pilot. The pilot was checked for the engine light concern and the technician reported the following: CONFIRMED DTC P0369 CMP SENSOR INTERMITTENT INTERRUPTION. FOUND CMP SENSOR TO HAVE WEAR FROM TIMING GEAR DUE TO CAMSHAFT MOVING SIDE TO SIDE. RECOMMEND REPLACING CAMSHAFT, SENSOR, THRUST PLATE, THRUST CAP, TIMING GEAR AND RELATED HARDWARE TO START. $3895.00 Also recommend replacement of timing belt with tensioner $516.00 There were not warning lamp before the failure. My engine just died and had to be towed to a dealership in Canada close to where I was residing. I felt my safety was at risk because my vehicle died in the middle of the highway and that could have lead to a crash. This is a know issue with 2016-2017 Pilots and Ridgeline. I know this from the service bulletin that was issued in January of 2018. However only certain vehicle were recalled for this exact issue. I contacted America Honda motor company and a Case #XXX was open. I asked to be reimbursed for repairs of $5200.00 Canadian to which they said no.

While driving my vehicle it begin making a rattling/clacking sound. The sound became more louder as we drove it home. The emissions system problems message appeared. We had a mechanic come to check it. He discovered the a rod bearing was damaged and we needed to replace a piston and other parts as well. We have been unable to drive it since due to safety issues.

I am the original owner of a 2017 Honda Pilot and bought the car new. It has 142,549 miles and been well maintained and adult driven. The engine started making a knocking noise. I took the car to the Honda dealer and they told me the engine needs to be replaced. Needless to say, they told me it would cost around 10 thousand dollars and was not covered under warranty. I opened a case with Honda (Case # 15988404) and was denied by their review process. I bought a Honda because it has a reputation for being reliable and should run for well over 250,000 miles. I am also aware that Honda has had many issues with their 3.5L V6 engine and there have been recalls for bad bearings causing premature engine failure. They also have issued recalls for this engine up to the 2016 model year. In my research for this issues, I have seen a lot of other owners reporting engine failures for the same engine for model years prior to 2016 model years. I would like for this filing to be another example on record of their engine failing prematurely. I am also aware that there has been a lawsuit filed against Honda and their 3.5L V6 engine for additional years. I hope this lends additional support to all the other owners who are experiencing the same issue.

Transmission and torque converter, were effected on my car. Safety concerns were witness when wife was driving on freeway with our 4 kids and car was jerking and not going like it’s was suppose to. We drove to slow lane were we proceeded to destination slowly . Problem was detected when transmission light came on when my wife and sister in law were driving on freeway. America Honda didnt want to look into it due to it being out of there warranty-of 150,000. So we took it to a transmission shop. We’re he diagnosed the code for the torque converter. The warning light came on at 166,000 miles. Thats when we’re actually aware of the issue. We never received a letter or call from America Honda warranty regarding this issue.

The vehicle started to Make loud clinking sound coming from engine. Went to dealership for diagnostic and high pressure fuel pump failed. Was quote 2000$ .

Component/System Failed: Engine – Excessive oil consumption (piston rings / internal engine components). The vehicle is available for inspection upon request. Description of the Problem: The engine is experiencing excessive oil consumption. During a monitored oil consumption test, approximately 0.9 quarts of oil were consumed over about 1,006 miles, which equals a consumption rate of approximately 1 quart per 1,118 miles. This rate is abnormally high and indicates an internal engine defect, likely related to piston rings and/or sealant failure. Safety Risk: Excessive oil consumption creates a significant safety risk. If the oil level drops too low between oil changes, it can lead to engine failure, sudden loss of power while driving, engine seizure, or stalling. This could place the driver and others at risk, especially at highway speeds or in traffic. There was no visible oil leak. The oil is being burned internally. Inspection / Confirmation: The issue has been monitored through an oil consumption test. Dealer diagnosis indicates internal engine repair is required (piston and seal-related repair). Estimated repair cost is approximately $6,000. Warning Lamps or Prior Symptoms: No external oil leak was present. Oil level dropped significantly between checks. (If applicable, add: “Oil warning light did/did not illuminate.” If unsure, write: UNKNOWN.) Manufacturer / Other Inspections: Vehicle has been inspected by dealership service department. (If Honda corporate has been cont

On Feb. 03, 2026 around 5:30 pm, driving 290 west going 65 mph. No cars on either side of me and the next closest car 6 lengths of me, my car slammed on the brakes and alarmed. The sudden braking lasted 1-2 seconds.

Engine was making a loud grinding noise and when my fiance got home from work it completely died out and will not turn over

Car bought at 103,000 miles engine failed at 109,700 verified thru Honda Dearler with metal shavings in number six (6) cylinder. Started ... with check engine display and started missing.

The contact owns a 2017 Honda Pilot. The contact stated that while his wife was driving approximately 65 MPH on the freeway, the vehicle stalled due to battery failure. There were no warning lights illuminated. The vehicle was towed to an independent mechanic, where the battery was replaced. After restarting the vehicle, the contact heard an abnormal knocking sound consistent with a rod knock. Additionally, the trunk handle paint had chipped and was rusted. The local dealer was contacted and referred the contact to the manufacturer for assistance. The manufacturer was contacted and confirmed that there were no recalls associated with the VIN. The failure mileage was approximately 51,000.

In June 2025, Honda sent a warranty extension reimbursement for the 2017 Honda Pilot for the torque converter-DTC P0741. Since the torque converter was defective, I replaced it on 5/7/21. I completed the reimbursement form Honda requested and included the invoice and proof of payment. On 9/30/25 Honda sent me an email stating that my reimbursement is being processed in 6-9 weeks. I have called several times and sent emails and they continue to tell me they will expedite my reimbursement. It has been over four months. My case # is: XXX. .

The contact owns a 2017 Honda Pilot. The contact stated that while driving between with the RPM between 2,000 and 2,500, the vehicle bucked. There was no warning light illuminated. The vehicle was taken to the dealer, where a transmission triple flush was performed; however, the failure recurred within 1-2 months. The vehicle was taken to an independent mechanic, where the transmission was serviced several times; however, the failure reoccurred. Transmission fluid was added to the vehicle; however, the failure persisted. The dealer was notified of the failure and advised the contact that another diagnostic test was needed. The vehicle was not repaired. The contact related the failure to TSB: 16-091 (Judder from the Torque Converter Lock-Up Clutch); however, the model year was not included. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 120,000.

I am submitting a safety complaint regarding a 2017 Honda Pilot experiencing a connecting rod bearing failure. Which has left my vehicle disabled. While driving on I-270 North, the vehicle suddenly made a loud “pop” noise and immediately lost power, creating a dangerous situation on a busy highway. Shortly afterward, the engine developed a very loud knocking noise, consistent with internal engine failure. The vehicle does not need to reproduce the concern, as multiple technicians were able to immediately hear the knocking upon inspection. The issue is constant and clearly present. There were no warning lights, no check engine light, and no prior indications of failure before the incident occurred. This sudden failure without warning presents a serious safety risk, especially at highway speeds. The vehicle has been regularly inspected and serviced, including services performed in dealership settings. The vehicle is currently available for inspection if needed. I am aware that similar model years have been affected by connecting rod bearing issues, and I believe this vehicle should be included or further investigated due to the sudden and dangerous nature of the failure.

While driving my 2017 Honda Pilot Elite, the vehicle has experienced four separate incidents of sudden and complete loss of power, including while traveling at highway speeds and during rush-hour traffic. The engine shuts off without warning, causing the vehicle to stop in traffic. In multiple incidents, the vehicle would not restart for several minutes. These incidents occurred on U.S. 19 and Interstate 275 in heavy traffic, creating an immediate risk of collision. In one incident, the vehicle died while traveling at highway speeds. In another, it shut off at a red light and blocked traffic during rush hour. The vehicle has been taken to an authorized Honda dealership multiple times. Diagnostic testing initially found no issues. Later visits attributed the problem to the battery, despite the battery being recently replaced and the condition recurring after replacement. The symptoms exactly match Honda Pilot start/stop engine failure recalls affecting nearby model years. However, because my model year is not included, the dealership refused to repair the vehicle in accordance with the recall, even when I offered to pay for the repair. I believe this represents a safety-related defect involving sudden engine shutdown while driving. The vehicle is unreliable and unsafe to operate. Furthermore, given the repeated failure of this vehicle, the dealership’s inability to permanently repair the condition after multiple attempts, and the ongoing safety risk, I am concerned this matter

Was driving down highway I40 near Nashville and the engine started making a noise. I was able to drive to my Mothers house. My Dad looked at it and stated it sounded like a rod knocking. So we went to take it to the dealer because after some research we found a recall for rod bearing failure. My vehicle was not on the recall list. We then proceeded to take the car to the dealer to check if there was a safety bulletin at the dealership when the engine locked up. My Dad came to rescue us and towed the car back to his and my mom’s house.

Emissions System Problem- UNKNOWN reason

My Honda Pilot has been diagnosed with engine failure by Royalty Auto in Kingsland, GA despite having been cared for quite well. This failure occurred well before reaching the expected life of the vehicle, yet outside the warranty window and having NO symptoms before the sudden failure. After doing some research on Pilot owner online forums, as well as, the NHTSA website, it seems similar complaints have been well reported and a recall has been issued for some vehicles in the same year and model under NHTSA campaign number 23V75100. This relates to Honda manufacturer recall XG1 and Honda recall GG0.

I received a letter from Honda regarding a warranty extension on the torque converter of my 2017 Honda Pilot. When I took the vehicle into the dealership, their senior technician confirmed the mechanical issues happening with the vehicle are aligned with the description of the concerns outlined in the warranty extension. The only element of the extension condition that was not happening was a code popping up on the screen. When I asked what conditions would need to take place for the code to pop up, they stated the torque converter would seize up while driving and cause the vehicle to be a hazard to those in the vehicle. When I explained this to Honda, they continued to deny the repair since the code did not populate. I am asking the NHTSA to look into this matter as I assume the purpose of the warranty extension was to repair an issue that could cause serious injury to the inhabitants of the vehicle, and not to rely on an electronic error code to pop up. Thank You

Turned car on and it was making a very loud sound coming from what sounded like the engine. Very loud when accelerating or stepping on the gas. Driving at lower speed was also loud. Unknown if it was safe to drive. Took to mechanic and was told it was the high pressure fuel pump. There were no warning lights or warnings.

I am writing to formally document a mechanical failure that occurred while I was driving on a major freeway. While traveling at highway speed, I suddenly heard loud, abnormal knocking and banging noises originating from the engine. Almost immediately, the vehicle lost power and became difficult to control while maintaining speed with surrounding traffic. Within moments, dashboard warning indicators illuminated, and engine performance rapidly deteriorated. Due to concerns for safety and to prevent further damage, I safely maneuvered the vehicle out of traffic and shut the engine off as soon as possible. After stopping, the engine was able to restart; however, it continued to produce concerning mechanical noises. The vehicle was no longer safely operable and required towing. Following inspection by two separate repair facilities, including a Honda dealership, both independently concluded that the engine had experienced a rod bearing failure. At the time of the incident, the vehicle had approximately 176,000 miles. Despite the mileage, the vehicle has been well maintained, including completion of the full 100,000-mile service and tune-up. This failure occurred without warning and created a hazardous situation due to the sudden loss of power while traveling at freeway speeds. I am concerned because Honda Pilot model years 2016, 2018, and 2019 have had recalls involving rod bearing failures. Given the circumstances and the nature of this failure, I believe Honda should consider re

My 2017 Honda Pilot (3.5L V6) is experiencing severe, rhythmic engine knocking and loss of power. The vehicle has no active warning lights or check engine codes. I am aware of the active NHTSA investigation PE25008 regarding connecting rod bearing seizure in this model year. The engine failure creates a significant safety risk, including potential stalling at highway speeds and the risk of engine fire. I am requesting that this vehicle be included in any forthcoming recall for the 3.5L V6 engine crankshaft/bearing defect.

With no warning, the engine has completely stopped while I was driving. The engine will not turn over at all after that moment. All maintenance was maintained on the vehicle, including regular oil changes. There were no lights, signals, or even engine sounds leading into it stopping. It appears that there are others who have had the same issue with this engine.

Vehicle: 2017 Honda Pilot VIN: [XXX] Mileage at incident: ~137,800 miles Description of the problem: My 2017 Honda Pilot has experienced repeated engine misfire issues involving cylinder 5 following a major engine repair performed by an authorized Honda dealership. On September 22, 2025, Honda of Kenosha, WI performed a camshaft and camshaft thrust cover repair on my vehicle at a cost of approximately $4,080. The dealership documented in the repair order that the camshaft thrust cover was not torqued to specification and that the engine misfired immediately after the repair. On December 5, 2025, approximately 44 days later, the vehicle was returned to the same dealership due to slow cold starts and warning lights. During the initial diagnostic at drop-off, the dealer documented a stored P0305 trouble code indicating a cylinder 5 misfire, which is the same cylinder involved after the prior camshaft/thrust cover repair. The dealership recommended and performed a battery replacement after a load test showed low reserve capacity. After replacement, the technician later confirmed that the battery was not the cause of the cylinder 5 misfire. The diagnostic codes were cleared, and the issue was described as intermittent. During the same visit, the dealer documented a tear in the lower portion of the engine air intake flex tube and evidence of a small rodent nest under the engine cover. However, the dealer also documented that no hoses, wiring, connectors, or sensors showed signs of

Transmission locked up and had to be replaced April 8 of 2025. I was blessed it did not lock up while I was driving, but did as soon as I pulled in my driveway. While driving that evening I had some issue with it not downshifting. When stopped in driveway could not restart the car. Had to have a special tow truck take it to the repair shop. I never got a warning light regarding the transmission needing to be checked. I had issues prior to the lock up, engine revving, gearshifting too late. Obvious transmissions issue. As I never got a warning light no code would show to have it repaired. I took it to the honda dealer for repair. After the replacement with another 9 cyclinder transmission the autoshut off is problematics causing me to stall out when stopping at lights and intersections. I had a previous experience with the 1999 honda odyessy and had 3 transmissions replaced. I am concerned about my safety as I could only replace it with another Honda 9 cylinder transmission.

Dealership believes the conneting rod bearing failure. Engine seized and was towed to dealership. So was driving 35mph and lost all power and braking on a 2 lane road. He was able to direct the car off the road safely without further incident. Car was towed to the dealership and has been there since.

What component or system failed or malfunctioned, and is it available for inspection upon request? 2017 Honda Pilot (127K miles) has experienced complete engine failure. Independent mechanic and Honda service have both said an engine replacement is required. Vehicle is at Honda of Katy and available for inspection. How was your safety or the safety of others put at risk? A breakdown occurred while my young son was driving. Thankfully, he was not on the highway, but the situation was distressing and has shaken my confidence in the vehicle's safety and reliability. He had to push it out of an intersection into a gas station, posing a safety risk to him, his passengers, and other cars on the road. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It was towed to our mechanic and then to Honda after his inspection found the problem to be consistent with the NHTSA recall 23V-751. Honda's inspection shows that the engine needs to be replaced. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? An engine light came on 11/17 while my son was driving (1 mile from home.) Once he arrived, we immediately took it to the shop, but the light disappeared between his stop at home and when we started it up again. The mechanic could find nothing wrong. He took a drive for a few miles and the light never came back on and no codes were found. The oil was then chang

I took my vehicle (2017 Honda pilot) to a Honda dealer in Selma, TX to have a pre-road trip checkup. They performed mileage related maintenance and assured me the vehicle was ready for my 2200 mile road trip. 600 miles into the trip, I stopped for gas. As I put the car in park, I received multiple errors on the driver's info panel. "1.Emissions system problem. 2.Transmission system problem. 3.Stop driving when safe. Transmission problem. See manual." Without any warning there was complete and sudden failure of the transmission. The car is available for inspection at a Honda dealer in Little Rock, AR where they ran diagnostics and found a list of problems. Apparently the Honda dealer in TX saw at least one of the errors and deleted it without informing me. If the transmission had failed while I was driving on the highway, average speeds of 70 mph, it could have caused a fatal accident. Right now the failed transmission has only been inspected by the Honda service dept in Little Rock, AR. There were no warnings from the vehicle to the driver prior to the complete and sudden failure whatsoever. After the failure the power train was locked in park. Drive, reverse, and neutral could not be engaged. I understand the mileage on the vehicle is high, but it is a grave safety concern when a major component of a vehicle can fail without reason or warning.

Engine connecting rod bearing failure diagnosed at the dealership. At 30mph, engine lost power and clunking noise was heard, coasted into a parking lot and had the vehicle towed to the Baierl Honda Wexford PA Dealership quoted total engine replacement at $9,978.93 +labor, + tax.

While traveling on highway a loud bang occurred, car jerked and started decelerating almost causing on accident. Car came to rest in middle of highway exit. Car was towed to Honda dealership where it was found to have a broken crankshaft rod bearing. No warning signs or symptoms had come prior to. New engine is required and confirmed by dealership.

2017 Honda Pilot Errors: lane keeping assist problem LKAS adaptive cruise control problem ACC road departure mitigation system problem RDM collision mitigation system problem CMBS or Collision Mitigation Braking System

This car loses speed when passing while highway driving. Car decelerates and throws you into neutral throws dash errors of "blind spot" & "transmission problem". I was luck to be able to get over 2 lanes to break down lane without being hit from behind on several occasions. Car message to put in park and turn off. Car was in neutral and wound not go into park. I had to put emergency break on and power down car in neutral. Waited a few minutes then restarted and no errors on dash. Car back to normal. Car has major faults and you can't show the codes when you get to dealer because they are gone then they also want to charge you $175 diagnostic fee. Car also has issues with the stop light idle turning off feature and not turning back on for 5-10 minutes yet another way someone can hit you from behind. I am stuck with this unsafe car and Honda never has to recall anything. I am going tomorrow yet again to try and get the Service Bulletin 23-078 Warranty Extension for the torque converter covered to see if that will resolve issue.

The Auto engine idle stop system just quits and stalls out at intersections. I have to put the car in park and restart the vehicle. Some times it takes a few minutes to get it moving. I’ve brought it to the dealership and they updated the software but it didn’t make any difference. It doesn’t happen all the time but it’s very frequent. I’ve started disabling it because it’s frightening when your call stalls and people are coming up behind you quickly at a green light. Today it’s entirely malfunctioning with a warning so I will have to take it back to the dealership again for them to tell me nothing is wrong. Honda should do a recall on this. I’ve searched the internet and I’m apparently one of many people having the same issues with this feature. Thanks so much.

The contact owns a 2017 Honda Pilot. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from the engine compartment, prompting the contact to discontinue driving the vehicle. The check engine warning light was illuminated. The vehicle was towed to the dealer, who diagnosed a failure with the connecting rod bearings, resulting in damage to the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 23V751000 (Engine and Engine Cooling), but the VIN was not included. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 100,000.

Auto-idle feature shut off vehicle at a stop and would not restart when light changed. Have to shut off vehicle and start like it was parked. Not safe in city traffic. Dealership said there is no issue with auto-idle feature

My engine started ticking at 113k, had fuel injectors replaced, came back in shortly after, they said engine failed, replaced with used engine… that one starting making noises, they apparently didn’t replace those fuel injectors either, so replaced those. Now catalytic converter is failing at 145k.

Car goes idle/shuts off with the auto shut off feature but won't turn back on automatically.

While driving the engine started smoking and stopped working. Upon checking by a mechanic it was found that the engine had no oil and was shut. Regular maintenance had been performed on a timely manner and there had been to previous issues or any oil leaks.

My Honda which has 120,000 miles is experiencing rod bearing issues. Honda refuses to help cover costs. I know there is an ongoing investigation with this year and similar mileage issues with Honda pilots so I am submitting this as proof of another case this is happening.

My 2017 Honda Pilot has been diagnosed with engine failure by John Hinderer Honda Heath, OH despite having been cared for quite well. This failure occurred well before reaching the expected life of the vehicle at 106,515 miles, yet outside the warranty window and having NO symptoms before the sudden failure. After doing some research on Pilot owner online forums, as well as, the NHTSA website, it seems similar complaints have been well reported and a recall has been issued for some vehicles in the same year and model under NHTSA campaign number 23V75100. This relates to Honda manufacturer recall XG1 and Honda recall GG0. I have reported my claim to Honda but received no resolution as of yet. My Manufacturer Claim Number with Honda Corp is 15916252. The failures of my engine should be considered in the NHTSA Campaign number 23V751000. Honda recall number XG1, Honda recall GG0. In addition, my claim should be considered as part of NHTSA Action Number: RQ24013. This is a current investigation as to why the NHTSA Campaign Number 23V751000 was limited to 249K vehicles while so many cars continue to have the same issue but fall out of the scope of the recall.

Complete engine failure on our 2017 Honda Pilot EX-L on October 7, 2025. We purchased it new in 2017 and have maintained it per Honda recommendations, including oil changes. We have all of the records to support this. Based on research and the audio diagnosis from two separate mechanics (one being Honda), the failure was likely caused by a known connecting rod bearing issue that led to a recall of 249K Hondas in 2023. Please include this in the NHTSA ODI evaluation PE25008, which is considering expanding the scope of that recall based on 414 additional incidents after the recall. Incident Timeline & Diagnostic Summary October 7, 2025 (≈12:30 PM) -Took the vehicle to Anthony’s Auto for an audio diagnosis based on a knocking sound. --Technician reported: knocking sound was slower than the piston rate, indicating a likely --rod bearing failure, leading to an inevitable and complete engine failure. --Technician confirmed: Oil level was normal (at the proper level). -Anthony’s Auto cautioned not to drive on the freeway, stating the engine could fail at any time. -I drove the vehicle home; less than ¼ mile from our house, the engine seized (knock → failure). I put the car in neutral and drifted into our neighborhood. -Vehicle was towed by AAA to Marin Honda (appointment scheduled for October 8). October 8, 2025 (~5:10 PM) -Marin Honda contacted us with their initial diagnosis and options: --Honda acknowledged that they had changed the oil at their facility in June 2025, per the sch

I am reporting a recurring “Keyless Start System Problem” warning on my 2017 Honda Pilot. This is a known and widespread issue affecting 2016–2017 Honda Pilot models, as acknowledged by Honda in Service Bulletin 20-117, which identifies a defect in the push-button start/stop switch assembly. In my vehicle, the warning appears intermittently, and the engine sometimes fails to start or requires multiple attempts to engage the ignition. This is a serious reliability and safety concern, as the vehicle may not start when needed, potentially leaving drivers stranded or unable to respond in emergencies. Although Honda recognizes the defect in their service bulletin, they have not issued an official recall and refuse to repair or replace the part outside of warranty coverage. Many owners are being forced to pay out-of-pocket for a clearly documented manufacturer fault. I respectfully request that the NHTSA investigate this issue and consider requiring Honda to issue a recall or provide a no-cost remedy for all affected 2016–2017 Honda Pilot vehicles. Additional details: •Model: Honda Pilot •Year: 2017 •Issue: “Keyless Start System Problem” warning, intermittent failure to start

In August 2022, with approx. 92,000 miles, my 2017 Honda Pilot received fuel injector replacement and a PCM update under Honda TSB 20-100, performed by Schaumburg Honda. This Technical Service Bulletin is known to have downstream impacts on emissions systems if the root cause is not fully corrected. On August 13, 2025, at 134,045 miles, the vehicle triggered a P0430 code (“Bank 2 Catalyst Efficiency Below Threshold”). Schaumburg Honda again replaced the injectors. Less than a month later, on September 8, 2025, at 135,101 miles, the vehicle triggered a second emissions code, P0420 (“Bank 1 Catalyst Efficiency Below Threshold”). Schaumburg Honda informed me that both catalytic converters had now failed and quoted over $5,800 in replacement costs. This sequence of events strongly suggests a long-term emissions defect potentially caused by unresolved impacts from TSB 20-100. American Honda denied goodwill assistance based on mileage, despite the clear connection to prior manufacturer-directed service. I have purchased several vehicles from this dealer over the years and have maintained all service through authorized Honda service centers. This raises safety and environmental concerns due to the catalytic converter failure, and may indicate a systemic issue tied to the TSB.

Multiple lights, for ACC, Lane Departure, Forward Collision Warning, and Lane Keeping Assistance system. None of the systems works. Safety of myself and others put at risk due to systems not working and preventing collision. The problem was confirmed by the dealer. Multipurpose camera not operating, required replacement of camera for systems to operate.

The contact owns a 2017 Honda Pilot. The contact stated while driving approximately 10-30 MPH, the vehicle stalled. There was no warning light illuminated. The contact was unable to pull over to the side of the road. The contact pushed the vehicle to the side of the road with assistance. The vehicle was towed to the residence. The vehicle was then towed to The Car Doctor, where it was diagnosed that the engine connecting rod bearing had failed. The vehicle was not repaired. The contact related the failure to NHTSA Action Number: PE25008 (Engine). The dealer and the manufacturer were notified of the failure, but no assistance was provided. The failure mileage was approximately 90,000.

- Emission systems problem despite changing fuel injectors twice -- Dealer found DTC P0420 . Performed 20-100 under warranty extension Dealer replaced the fuel injectors last year in 2024 when the emissions systems problem indicator light appeared and recently again on September 04 2025. The repairs were performed free of charge. - The indicator now appears again on and off in the last two weeks after September 15, 2025. - The indicator sometimes shows up immediately after starting the engine and sometimes turn on while driving.

Auto Start/Stop Issue. I finally experienced what some other members of my family have experienced with this car. My Honda Pilot stalled at a stop light in heavy traffic after the engine was turned off when I stopped at the light using the auto start/stop function. After I released the brake when the light turned green, the car did not start.

120k J35Y6 engine with good oil service and no major issues before. I heard a tapping/ticking noise emanating from the engine. So I brought the car to the local Honda service center for a diagnosis. Without opening the engine (i.e. purely based off sound) they claimed that the sound was "rod knock" caused by the crankshaft pin and the connecting rod bearing, and that the engine was effectively totaled. Upon doing some research I learned that that exact issue is the subject of an ongoing investigation so I decided to submit this report. My receipt and outline of that engine diagnosis is attached.

Vehicle Mileage - 87,200 In February I had the Fuel Pump recall completed after over a year of waiting for the parts to come to the Honda Dealer. I first noticed the recall being issued when I received my notice to renew my registration. Then, I received an official notice from Honda a few months later in the mail. I sent an online appointment form around that time and Bobbi at Honda told me that they did not have the parts and I should wait to check again in a few months as it was impossible for them to get the parts in. So I did - I periodically would call her directly in the service department to check and they still did not have it. FINALLY they got the parts in, and she let me know I could schedule to have the recall fixed. I came in about a week later in early February and had it fixed. Since then I've had issues with my emissions system light turning on randomly - usually whenever there was significant changes in the weather - very hot/much cooler. I just took it into the dealership on 8/4/25 because the light the last few days had stayed on. The dealership told me they needed to check the fuel pump for sure because when I explained the situation to them, it very well could be related to the recall being fixed. They informed me they ran several tests and discovered that I need to replace my catalytic converter. It is clear at this mileage on my Honda Pilot and the delays in having the fuel pump recall fixed caused the damage to the catalytic converter. I spent almost a
