Power Train Problems of Honda Pilot - part 1

The manufacturer’s defective fuel delivery system (faulty fuel injectors covered under Honda TSB #19-056) causes severe engine cylinder misfires, dropping the vehicle into an immediate, unpredictable, and sluggish 'limp mode' while driving at highway speeds. This sudden loss of power and acceleration creates a severe traffic hazard, preventing the vehicle from keeping pace with traffic or safely merging. The primary fueling malfunction has also led to cascading damage, sequentially melting and destroying both catalytic converters and prematurely destroying brand-new spark plugs in under 5,300 miles due to raw fuel dumping into the exhaust stream.

While driving my 2019 Honda Pilot at highway speeds 70 mph, the dashboard suddenly displayed a severe safety warning stating "transmission temp too hot. " there was no prior warning, mechanical symptom, or heavy cargo towing to cause this. The sudden warning forced me to immediately navigate across multiple lanes of fast-moving traffic to pull onto the shoulder of the highway, creating an immediate and dangerous crash hazard. This is a severe mechanical failure that occurs without reason under standard driving conditions, heavily compromising vehicle reliability and occupant safety on the highway. The vehicle has been exclusively and regularly maintained at an authorized Honda dealership according to all factory recommendations. The sudden transmission overheating and subsequent safety hazard occurred despite flawless maintenance compliance, proving this is a severe manufacturing or chemical fluid defect and not a case of owner neglect.

My car would rev without increasing speed and would jerk with braking and acceleration. The Honda technician diagnosed a transmission problem called a slip flare and the transmission is being replaced under warranty at 28k miles. I do not believe this caused a safety issue because I caught it early but it took the dealership a couple days to reproduce the issue. There were no warning lights or error codes alerting an issue.

When I am driving my Honda sometimes will change gears "hard" or sometimes when I press the gas pedal it will hesitate and not go when I am trying to go around another car. I have had my car for less than a year and it has happened through out my ownership.

After automatic braking engaged, within a couple days car will make a zipper noise and gas pedal will not work. Have to press it 5-6 times and then it will start working again. Very dangerous when you have cars traveling behind you and you basically start slowing down immediately. But today, not sure if related, backed out of driveway on a slope, car went immediately to park with a large sound like the bottom falling out of the car and shook the car. Several warnings kept flashing (emissions, transmission, and p for park was flashing). I powered car off and back on was able put in n to let it coast backward to get out of the road. Completely shut everything off waited a couple minutes and was able to drive it back to my driveway and there was fluid leaking from underneath halfway between the front to tires. Calling dealership tomorrow.

Took Pilot to reilly's for free diagnostic reading. Showed misfires in cylinders 4 & 5 & random misfires. Then took to son's Honda and paid for the same diagnostic readings which were the same. The Pilot drives in a "limp mode" due to the issue. This issue is a known Honda issue for this year and make model. They have granted some Pilots an extended warranty to resolve the known issues. They say mine doesn't qualify even though it is the exact same issue. Defects with their fuel injector system. A secondary issue is the transmission. We were traveling 2 hours away on the highway when we got a warning to pull over. Our transmission fluid was too hot. This is another issue I have found to be a common problem with the 2019 Honda Pilot's and their redesign transmission system.

Vehicle: 2019 Honda Pilot ex VIN: [xxx] current mileage: 77,000 miles complaint description: I am filing a critical safety complaint regarding a catastrophic transmission failure that actively disables my vehicle's advanced driver-assist and automated safety systems while driving, creating a severe crash hazard. At approximately 36,085 miles, the vehicle experienced a severe torque converter judder. The dealership performed an 11-quart transmission fluid service. Immediately following this service, the vehicle began suffering from unpredictable, cascading dashboard warning lights that completely disable the vehicle's automated safety braking, forward-facing camera suites, and vehicle stability systems. The dealership repeatedly misdiagnosed this powertrain fault as a camera/sensor issue, charging me out-of-pocket for a front multipurpose camera replacement that did not resolve the issue. At 77,000 miles, the transmission suffered a complete failure. A diagnostic tear-down confirmed a stuck solenoid valve and destructive metal shards circulating throughout the transmission and fluid lines. The primary safety hazard is that the mechanical failure of the powertrain and torque converter actively sends erratic data to the vehicle's central computer, instantly shutting down the automatic emergency braking system, lane-keep assist, and forward collision warnings while the vehicle is in motion on public roads. This forces the driver to operate without critical automated safety features unexpectedly. Honda has issued an extended warranty for transmission judder on certain 2019 Pilots ([xxx]), but claims my specific VIN is excluded despite experiencing the exact same catastrophic mechanical and electronic safety failure. I request an investigation into this safety-disabling defect. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I noticed up and down motion that seemed like a rotor problem. I had them look at the rotors and breaks. It was not them. They balance the tires and that didn't fix it. I asked them to do a nvh test to find where the vibration was coming from they told me they would do it and kept my car for the weekend. Monday rolls around and they tell me they won't do it. I was able to find a nvh app which you will see in the results attached. They still refused to do the test. By government and Honda policy they are required to have this equipment. They just refuse to do it because this it is sitting in my driveway accruing non repair time because its not safe or mechanically sound. I still have 13000 miles left on my 5 yr 60000 mile warranty.

The contact owns a 2016 Honda Pilot. The contact stated that while accelerating from a stop, the vehicle lost automotive power, and the battery, oil, and information warning lights remained illuminated. Several minutes later, the vehicle was restarted, and the contact continued driving. Another failure occurred while attempting to accelerate from a stop, and the transmission shifted into neutral, the brake pedal became stiff, and the contact was forced to restart the vehicle. The vehicle was not diagnosed. The failure mileage was 98,512.

The contact owns a 2025 Honda Pilot. The contact stated that the vehicle recently received routine maintenance by the dealer; however, approximately one month later while driving at an undisclosed speed, the vehicle lost power and came to a complete stop. The messages “transmission temperature -avoid heavy acceleration and high speeds”, “transmission system problem”, “apply parking brake when parked”, “emissions system problem”, and “power may be reduced - see your dealer” messages were displayed. The vehicle was towed to a dealer and was diagnosed with transmission. The contact was informed that the transmission needed to be replaced. The manufacturer was notified of the failure, and the vehicle was repaired. The failure mileage was 52,646.

My 2022 Honda Pilot has experienced a serious safety malfunction involving its idle stop system. When the vehicle stopped and idle stop activated, the vehicle unexpectedly shifted into neutral and would not allow me to shift back into drive. I had to turn the vehicle completely off and restart it before I could drive again. This left the vehicle temporarily unable to move in traffic. Since xxx, the vehicle has required five replacement batteries, three installed by Honda dealerships and two elsewhere. In xxx, Honda sent us a letter titled "pgm-fi idle stop software update" and "warranty extension: engine does not auto restart after entering auto idle stop. " the notice referenced Honda service bulletins 23-008, 23-009, and 23-010. During our most recent visit to Honda of [xxx], the dealership diagnosed a failed battery and charged us $634 for replacement parts and labor. When we picked up the vehicle, we specifically asked whether Honda's pgm-fi software update had been performed. The service representative stated that the update was unnecessary because diagnostic testing did not identify the issue. We have not received confirmation that the software update was completed. I am concerned that the underlying cause of this malfunction has not been identified and that the vehicle could unexpectedly become unable to move in traffic again. I request that NHTSA investigate this potential safety defect. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The engine required a short block replacement at approximately 40,000 miles. There was a severe knocking sound and the dealer diagnosed heavy scoring and abnormal wear present on the front bank cylinder walls. The result was excessive internal engine clearance and cylinder wall damage. Engine cylinder piston block holes were worn beyond spec. After 33 days the vehicle was returned and developed a growling/grinding noise when the ac was in operation and at lower speeds that followed the rpms. Vehicle was returned to dealer and told sound was normal operation for this model and stated it was coming from ac compressor. Independent shop verified 2 days later ac compressor was failing and possible metal contamination. Ac compressor is backordered with no eta. Advised to not use ac or defroster to avoid seizing and causing serpentine belt to snap. Advised Honda customer care and assigned case manager who was made aware of knock and compressor failure and contacted dealer who stated vehicle could not be seen for 7 days due to being booked. Advised case manager of vehicle safety concern with internal engine failure damage and failing ac system and was denied emergency loaner or assistance and told it was all they could do. Vehicle now unsafe due to both with no timeline for fixing and known hazards due to severe engine failures and associated issues with main systems.

I am filing this complaint regarding my new Honda Pilot with only approximately 300 miles. The vehicle has multiple serious problems that I believe should be investigated as potential safety defects. Steering/rack clicking: the steering system produces a loud clicking/rattling noise that sounds like loose marbles, especially at low speeds and during slow turns. This appears to come from the steering rack/steering assembly. There are multiple reports from Honda Pilot owners on online forums describing the same or very similar steering noise dating back to the 2023 redesign. It is extremely concerning that the issue continues in newer vehicles. A potential defect involving the steering system could affect steering control and represents a serious safety concern. Transmission jerking: the transmission jerks, lurches, and rocks the vehicle at low speeds, particularly when shifting into drive, reverse, and between 1st and 2nd gear. There is sometimes hesitation followed by an abrupt engagement. Unexpected movement during parking, reversing, or stop-and-go traffic could create a safety risk. A/c not cooling: the a/c is not properly cooling the cabin and has a condenser/refrigerant leak. In extreme temperatures, inadequate cabin cooling can also become a safety concern, particularly for children and other vulnerable passengers. It is unacceptable for a vehicle with only 300 miles to have these significant issues. Given the multiple owner reports and the apparent persistence of the steering problem across model years, I strongly believe NHTSA should investigate these complaints and determine whether Honda should be required to conduct a safety recall. Honda should not wait for accidents or injuries before taking action. If these are widespread defects, Honda should issue a recall and provide a permanent repair to affected owners. I am requesting that NHTSA investigate these issues and take appropriate action to protect Honda Pilot owners and the public.

The contact owns a 2019 Honda Pilot. The contact stated that the check engine warning light was illuminated. The vehicle was taken to the dealer and was diagnosed with fuel injector failure. The contact was informed that the fuel injectors needed to be replaced. The fuel injectors were replaced. The contact became aware of technical service bulletin: 21-010, NHTSA id number: 10187008 (engine and engine cooling, electrical system, equipment, power train). The contact called the dealer, and it was confirmed that the VIN was not covered under an extended warranty. The manufacturer was informed of the issue and confirmed that the vehicle was not included. The manufacturer referred the contact to the NHTSA hotline to report the failure. The failure mileage was 91,670.

The vehicle since purchase has a delay of a few seconds after hitting the gas pedal to move forward. Once the vehicle does decide to move, it surges to a high rpm before switching to second gear moving forward rather aggressively. This causes the vehicle to be unpredictable and unsafe when making decisions in navigating traffic.

My 2022 Honda Pilot black edition (VIN 5fnyf6h07nb042859, 62,900 miles) has multiple intermittent safety?critical failures involving the transmission, acceleration, adaptive cruise control, and hvac blower. These issues occur without warning and without diagnostic trouble codes. Transmission/acceleration failure: most recent incident was 7/30/26 on highway 71 during heavy traffic. The vehicle twice experienced rapid deceleration with no ability to reach a safety stop. Rpm dropped below 1000, then spiked to 6,000–8,000 while the vehicle continued to lose speed. Acceleration returned only after several seconds. This also occurs during highway merging and uphill acceleration. Additionally, when disengaging cruise control and immediately pressing the accelerator, the vehicle loses speed, rpm drops abnormally low, then spikes before power returns. Adaptive cruise control/Honda sensing failure: on 7/30/26, the vehicle rapidly decelerated when a semi?truck was beside me, despite no vehicle ahead. The week prior, while driving several states away, setting cruise at 70 mph caused sudden deceleration and cruise resetting itself to ~54 mph. These events resemble phantom braking and radar mis?targeting. Hvac blower failure: during a long multi?state trip the week prior, the ac blower (speed 3–4) intermittently stopped blowing for several seconds, then resumed at the same speed with no change to the display. These failures affect powertrain, forward collision avoidance, vehicle speed control, electrical systems, and cabin equipment. The dealership (roush Honda, westerville OH) cannot replicate the issues and reports no stored codes. These defects pose significant safety risks.

Vehicle had an engine fire yesterday. Inner cv boot is burned. Luckily fire was put out quickly with a fire extinguisher.

The steering wheel became extremely difficult for my husband to turn. Power steering went out on my 2025 Honda Pilot trailsport. Numerous warnings were then displayed on the vehicle's dashboard screen, it was impossible to drive, and caused us to have to get towed. We had it towed to a Honda dealer for repair, where it was discovered that the steering wheel had more turns in one direction than the other, the shaft boot was misplaced, non-factory pins on the steering rack were noted, and the clock spring was stuck reading 508 degrees. Furthermore, the steering wheel rack gearbox had to be replaced following a steering angle sensor failure in my 2025 Honda Pilot trailsport. This is a serious safety issue and should have never have happened in such a new vehicle. This incident not only put my family's lives at risk, but also everyone else on the roadway. Why did my vehicle that I bought brand new and have only serviced at Honda have non-factory parts?.

My 2016 Honda Pilot has 97,500 miles. The engine stop working and I have it replaced a used 3. 5 engine. The transmission has transmission overheating problem and I took a picture on the dash board. I show it to the service advisor and they won't acknowledge about the overheating problem. Honda care customer service won't do anything regarding the engine and transmission problem.

The 6-speed automatic transmission on my 2016 Honda Pilot ex-l (103,200 miles) has experienced a severe mechanical failure casing dangerously hard, violent gear shifts during both acceleration and deceleration. Critically, no dashboard warning lights or malfunction indicator lamps illuminated while this dangerous driving condition persisted, leaving me with no advance warning of a safety hazard. A subsequent diagnostic scan at an authorized Honda dealership revealed hidden diagnostic trouble code p0776 (pressure control solenoid "b" performance or stuck off) and a failing torque converted. The severe, unpredictable jerking and hesitation during shifting creates an immediate traffic hazard during acceleration in traffic. Approximately 45 days prior, an out-of-town Honda dealership performed a prescribed triple fluid flush when the issue first arose. Then, 5 days later, my local Honda dealership performed the prescribed software update for shifting issues, which failed to remedy the underlying defect again. The dealership has now quoted $11,000 + for a full replacement of the transmission and torque converted. American Honda corporate has opened case number: 16606142 to track this defect.

I had two time between the week of June 30 th to July 4 thank July 13 to July 16 th on the excessive heat days my car was making a lot of sound from driving side as well full vibrations on steering and floor I went to page Honda dealer ship they said short block problem and they they are raising request to Honda my mileage is 58800 2023 Honda Pilot bought in may 2023 which is under power train warranty but did not receive any email or any paperwork from Honda dealer ship.

* collision mitigation braking system (cmbs) – southeastern Honda: shortly after purchase, the cmbs repeatedly slammed on emergency brakes without cause, incorrectly flagging adjacent or oncoming vehicles as collision threats. I presented video and photo evidence to southeastern Honda. The service manager dismissed the hazard, telling me I "just have to learn how to drive the car with these driver assist features. " fearing an accident, I was forced to permanently disable the system. * starter failure / battery issues – space coast Honda: the vehicle went through four batteries and repeatedly failed to restart when auto idle stop engaged, stranding my wife and children in parking lots and active traffic. I brought the car in multiple times insisting the starter was the issue, but space coast Honda refused to replace it because no codes were present and my VIN wasn't attached to a recall. Once out of warranty, I replaced the starter out-of-pocket, which permanently resolved the issue. Teardown of the original starter revealed extensive heat damage, burned insulation, and charred components. * current engine concern – space coast Honda: the engine now exhibits rod bearing failure symptoms aligned with recall 23v-751, including knocking and metallic debris in the oil and filter. I brought the vehicle and photo evidence to space coast Honda. One staff member claimed metal in the oil was "normal," while another disagreed. I left the car for evaluation, but two days later learned no inspection was done; they claimed Honda would deny it based on VIN exclusion and quoted $13,500 for a used engine. When I insisted they present my case to Honda anyway, they abruptly raised the inspection fee to $800—despite having completed zero diagnostics over two days.

2018 Honda Pilot transmission failed at only 34,726 miles I want to share my experience so other Honda owners are aware of a very premature transmission failure. I am the original owner of a 2018 Honda Pilot with only 34,726 miles. My family has trusted Honda for many years, and my wife also drives a Honda hr-v. We believed Honda vehicles were reliable. While driving, my Pilot suddenly showed a “transmission system problem” warning. The vehicle became very slow and later was unable to engage into gear. I had to tow it to capital Honda in san jose. Capital Honda diagnosed a complete transmission failure requiring a full replacement. The repair cost was about $11,800. I appreciate that american Honda provided goodwill assistance and covered a large portion of the repair. With that assistance, my out-of-pocket cost was reduced to $3,500. However, I am frustrated and disappointed that a Honda transmission could fail completely at only 34,726 miles. This is unacceptable for such a low-mileage vehicle, especially from a company known for engineering quality and reliability. All maintenance was completed on time at Honda dealerships. About six months before the failure, the transmission fluid service was also performed at a Honda dealer. I did not neglect this vehicle. Because of the low mileage, I asked american Honda to review my case for additional goodwill assistance. Unfortunately, that request was declined. Again, I appreciate the assistance already provided, but as a loyal Honda customer, I am deeply disappointed that I still have to pay $3,500 for a major transmission failure that happened far too early. I am sharing this so other Honda Pilot owners can watch for warning signs such as warning messages, delayed engagement, slipping, jerking, or abnormal shifting. Please keep your service records and report serious issues if they occur. Honda built its reputation on reliability, but this experience has made me question that reputation.

A safety concern with some Honda Pilot models involves a potential transmission defect that can cause the vehicle to hesitate or fail to accelerate when the driver presses the accelerator. This unexpected loss of power can create hazardous situations, particularly when merging into traffic, crossing intersections, or attempting to avoid obstacles. Drivers have reported delayed engagement and inconsistent acceleration, raising concerns about the reliability and safety of the vehicle's transmission system.

On June 25, 2026 my 2025 Honda Pilot elite (47,503 miles) upon ignition had every warning light in the system illuminate sequentially without any prior incident. I had never experienced any indication of malfunction, including warning lights or messages. The emissions system problem light remained illuminated on the dashboard and, after review of the owner's manual instructions to avoid heavy acceleration and high speed, I had the vehicle towed by aaa on a flatbed truck 75 miles to my home. The incident occurred during the evening and the next morning I drove the vehicle to herb chambers Honda of seekonk, the dealer who has performed every service on the vehicle, including recalls. Of note is that the service team at the Honda dealer, specifically malainne costa, has been exceptional in addressing this issue. American Honda was consulted to determine the best plan for resolution. I understand that american Honda is trying to work through necessary adjustments with the new 2025 model year. One month after the incident, my vehicle remains at the dealer. I learned that the two cylinder heads in the engine block on my vehicle need to be replaced and those parts are still on backorder. Another engine component system may require replacement due to calcium buildup on the intake valves. I was assured that my driving habits were not a factor in this incident. My concern is that this incident occurred at a time when I was in a safe location and was able to await the arrival of aaa without worry about my personal safety. I bought the brand new vehicle in November, 2024 and it is obvious that I drive a significant amount of miles per year. I worry about the safety risk of other drivers having a similar experience in a less than optimal location especially since there was no indication of a problem prior to this critical incident. I share this incident in the spirit of exploring whether this is a systemwide problem that may result in a safety recall by Honda.

I am filing a safety complaint regarding a 2024 Honda Pilot touring with approximately 46,000 miles. The exact component or system that failed is currently unknown. My best assessment is that this may involve the electrical system, powertrain, engine control/software system, charging system, auto idle stop system, or another related vehicle control system. The vehicle is currently available for inspection upon request. The vehicle has had intermittent multiple warning lights appear on the dashboard. On June 7, 2026 around 9:00pm, while the vehicle was in drive, the vehicle shut off/lost power. This created a serious safety risk because the vehicle was being operated when the shutdown/loss-of-power event occurred. I am concerned this could happen again while driving, including at freeway speeds or while transporting a child. The problem has not yet been reproduced or confirmed by the dealer. The vehicle was taken to a Honda authorized dealership for inspection. The dealership advised that the battery tested fine and that no diagnostic trouble codes were found so far. Diagnostics are still pending, and as of this complaint, no confirmed cause, diagnosis, or repair has been provided. The vehicle has not been inspected by police or insurance representatives. American Honda motor CO. Has been contacted, and a case has been opened regarding this concern. Warning lamps/symptoms did occur before the shutdown/loss-of-power event. The vehicle had intermittent multiple warning lights on the dashboard before/around the time of the incident. The warning lights first appeared on or around June 3, 2026. The shutdown/loss-of-power event occurred on or around June 7, 2026. I am requesting that NHTSA document this safety issue involving a 2024 Honda Pilot touring shutting off/loss of power while in drive with no confirmed diagnosis or repair at this time.

I own a 2017 Honda Pilot equipped with the 9-speed automatic transmission. I am reporting what I believe may be transmission/torque-converter failure and a potential safety concern. The vehicle began experiencing shuddering, jerking, and hesitation. There is significant rpm fluctuation and harsh shifting. The problem occurs on highway speeds, accelerating or shifting lanes, 40–60 mph. During these episodes, the acceleration stalls and is accident prone. 8 months ago, I brought the vehicle to an authorized Honda dealer because of these symptoms, they couldn't get the code. 3 months ago, I went again for same issues, the dealer diagnosed a damaged air-intake hose and I paid for replacement. However, immediately driving off the lot, the original symptoms continued after the repair. I returned the vehicle to the Honda dealership because the problem persisted. The dealership has now diagnosed transmission failure and has estimated the repair at approximately $10,000. American Honda has offered approximately 60% goodwill assistance toward the repair, leaving me responsible for approximately $4,000. I am concerned because there are numerous reports involving transmission and torque-converter problems in 2017 Honda Pilots. Honda has issued technical service information concerning transmission and torque-converter conditions in this model year, including information involving the 9-speed automatic transmission. I am also aware of other NHTSA complaints involving premature 9-speed transmission and torque-converter failure in 2017 Honda Pilots. My vehicle has previously required other Honda-recognized repairs, including fuel-injector/emissions-related repairs that Honda covered. I am submitting this complaint because a transmission or torque-converter malfunction that causes hesitation, harsh or unexpected shifting, loss of acceleration, or loss of motive power can create a serious safety risk, particularly while entering or traveling on a highway or crossing traffic.

Driving to work and, all of a sudden, the dashboard lights flicker and the car says the transmission has issues. The car advises us to pull over out of the highway. This was driving to work. The car completely stops working. The dealer says the transmission is dead. This is a car that is a 2019 Honda Pilot. 7 years old. It was bought through Honda and serviced at Honda. The transmission should not go out this early. We also purchased a 2019 Honda odyssey in may 2023. In December 2023, the tranmission and to be replaced. I've owned 6 Hondas in twenty years and the only ones that are problems are the 2019 version.

We believe there is a serious safety issue with our 2026 Honda Pilot with its delayed acceleration. There is a distinct delay between pushing the gas pedal and the engine engaging/moving the car forward (approximately 2 seconds). This has nothing to do with the auto idle stop function. I've attached a vlinker mc+ device to our car's obd port and used the car scanner mobile app ([xxx]) to measure the delay. I'm attaching visual proof of the delay between the gas pedal and the engine rpms. The reason we believe this is a safety issue is that when trying to merge into traffic (think of crossing 2 lanes to turn left) the delay means you have no confidence you'll make it safely across without getting broadsided because the car won't accelerate when it is needed. This sounds eerily similar to NHTSA 25v-031. The engine hesitation will cause an accident at some point. This issue was reported to Honda customer care (case #xxx) but they declined to address the situation and pushed it back on the local Honda dealer. "all technical evaluations and potential escalations must originate with, and be requested by, an authorized Honda dealership based on their inspection findings. " we already brought this up with our local Honda dealer in a service call on xxx. It was documented in our service record with them. They asked us to submit the issue to Honda customer care. Since all parties are pointing the finger at each other, we are raising this safety issue with NHTSA. This is a new vehicle purchased at the end of may, 2026. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I am having an issue with the start stop function on my 2021 Honda Pilot. When active, the start stop struggles to restart after it is engaged at a stop light. There have been two instances in the last two weeks where the vehicle did not restart on its own and needed to be restarted manually. Spoke to the dealer service team and they indicated there were no known recalls and it would be out of pocket for me to diagnose and repair.

On may 23, 2026 I was driving family and friends around san francisco, CA in my 2017 Honda Pilot (48k miles). We were driving up multiple steep hills, up to a 20% grade in some places with a full car of 7 people. The car handled it well. However, as we neared my home 25 miles away, the car started shaking and the check engine light started flashing. We searched online and the advice was to pull over immediately to prevent the car from overheating and causing permanent, expensive damage. We eventually made it home, shaken, and didn't touch the car for a couple days to let it rest. I learned that there is a warranty extension "warranty extension TSB 20-100" for what seems like this exact problem concerning the fuel injectors. The spark plugs have been replaced in the last year, which eliminates that as a potential issue. The next week, I took the car to Honda san carlos where it's been maintained most of its life. I informed them of the symptoms and that the car is eligible for this warranty extension. They tested it and found nothing. I told them that testing it in the shop or driving it around a few minutes on flat ground with one person is not going to replicate the driving conditions we encountered but they didn't seem to care and I had to pay $250 anyway. I took this to another dealership and the guy said it sounded exactly like an warranty extension TSB 20-100 issue. They tested it and also could not find anything. I called Honda corporate and they will also do nothing. This is clearly a safety issue as this problem will happen again at some point. I have a family and young children and do not want to be stuck on the freeway as a road hazard to ourselves and other drivers. Honda has clearly identified this as a problem yet they won't authorize the repair. They are waiting for this to happen again before they'll fix it, and who knows if this ticking time bomb will occur in a safe place or a dangerous one.

The contact owns a 2016 Honda Pilot. The contact stated that while driving at an undisclosed speed, the vehicle idled roughly and an abnormal noise was coming from the rear of the vehicle with no warning lights illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that the rear differential had failed and needed to be replaced. The vehicle was not repaired. The vehicle was then taken to the dealer, where the same diagnosis was provided. The contact was informed that the rear differential had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 180,000.

While operating my vehicle on a public roadway, the vehicle suffered a sudden, catastrophic loss of transmission hydraulic pressure and vehicle propulsion, accompanied by a dashboard warning light with a blinking "d". The vehicle completely stopped delivering power to the drive wheels while moving with traffic, creating an immediate and severe safety hazard for a rear-end collision on an active road. We pulled into the high school parking lot, stopped the car, then restarted it. It had the error on the dashboard, but we were able to get it safely home, where it was towed to the dealership later. ?the vehicle was towed to dick hannah Honda (the local authorized dealership). The service department scanned the onboard computer (from the parking lot, no actual physical inspection done) and pulled internal transmission fault codes p0730 (incorrect gear ratio) and p0746 (pressure control solenoid "a" performance/stuck off). Based solely on these electronic fault codes, the dealership stated that the internal mechanics of the zf 9-speed transmission had completely failed. They stated the transmission is completely unrepairable and quoted a full replacement cost of $11,984. 41. ?prior to this failure, the vehicle had service documentation and inspection records from authorized Honda franchise technicians, who repeatedly marked the transmission condition and vehicle health check sheets as completely healthy and "green" at every visit for 60,000 miles by american Honda motor CO. Case management was contacted (case #16371194), but they refused any financial goodwill assistance. ?this sudden operational failure of the zf 9-speed transmission platform without any prior maintenance minders given by the computer system. This failure matches the exact software calibration and pressure defects currently cited in ongoing consumer protection litigation involving the 2016-2022 Honda Pilot 9-speed drivetrain.
