2016 Honda Pilot: engine knocking or ticking

Filed Nov 3, 2026 · Engine · MA

I was stopped at a traffic light just off a highway exit ramp, with my vehicle in drive. When the light changed and I attempted to accelerate, the vehicle would not move forward. I immediately shut off the engine. Because I was stopped in an active traffic lane near a highway ramp, I became concerned for my safety and restarted the vehicle in an attempt to move out of traffic. Upon restarting the engine, I heard a knocking noise that had not been present previously. I was able to move the vehicle approximately five feet to a safe position before shutting it off again.I did not attempt to drive the vehicle any further because I was concerned about causing additional damage. The entire incident unfolded within seconds. This was a single, sudden failure rather than a recurring issue. The knocking occurred only during the period leading up to the vehicle becoming inoperable. This was not an ongoing issue that I had been experiencing for months. Car would not accelerate, I began experiencing a knocking noise from the engine. The vehicle subsequently stopped running.

Hello, While driving, the engine developed a distinct, heavy metallic knocking sound coming from the bottom end. I took the vehicle to an independent repair shop for inspection, where the mechanic drained the oil and cut open the oil filter. The filter pleats contained significant metallic debris and bearing shavings, confirming internal connecting rod bearing failure. The mechanic confirmed the engine has severe bottom-end damage requiring a complete replacement. The damaged oil filter and engine are available for inspection upon request. According to the previous owner, the vehicle was brought to an official Honda dealership in April 2024 for this exact knocking noise. Per the seller, the dealership misdiagnosed the engine knock as a faulty timing belt tensioner and charged approximately $2,000 to replace the timing belt assembly. That repair failed to resolve the noise, but because of the dealer's misdiagnosis, the vehicle continued to be driven with failing rod bearings. This failure poses an immediate safety hazard. Sudden connecting rod bearing failure on the highway can lead to complete engine seizure, abrupt loss of power at high speeds, power steering loss, or a thrown rod causing an engine fire, putting passengers and surrounding traffic at severe risk. Prior to the diagnostic check, there were no low oil pressure warning lights or dashboard indicators. This failure directly aligns with the federal safety agency Campaign 23V‑751 (Honda Recall XG1) for 3.5L V6 (J35) engine connecting rod bearing defects. This 2016 Honda Pilot has the exact affected J35 engine type and exhibits the exact failure mechanism described in the recall, yet this specific VIN was excluded. Given that non-recalled VINs are experiencing identical catastrophic bearing failures, Honda should expand the recall parameters or cover the replacement engine cost for vehicles with this confirmed defect.

Connecting rod spun a bearing/ rod knock Verified le customer's concern regarding an abnormal engine knockır oise. Conducted a diagnostic inspection and confirmed pronounced metallic knocking noise originating from the ower engine assembly. Used a mechanic's stethoscope tr isolate the noise to the crankshaft/connecting rod area technician verified a catastrophic lower-end engine failure. Specifically, the diagnostic notes state: "Connecting rod spun a bearing / rod knock Verified" "Pronounced metallic knocking noise originating from the lower engine assembly" "Testing indicated that the knocking noise was most prominent at cylinder #2, consistent with excessive connecting rod bearing clearance and a spun connecting rod bearing." Furthermore, the computer scan sheet shows zero codes for low oil pressure, engine overheating, or vehicle neglect. The temporary misfire codes listed occurred solely because the technician intentionally disconnected individual ignition coils to isolate the mechanical knocking sound. This precise diagnosis—a spun connecting rod bearing at cylinder #2 due to improper clearance—is the textbook definition of the inherent manufacturing defect that triggered the major the federal safety agency Action regarding Honda 3.5L V6 engines. Because my vehicle was manufactured at the Lincoln, Alabama plant and has been maintained perfectly by Honda its entire life, this failure is undeniably due to a factory structural defect rather than normal wear and tear or owner oversight.

While driving our 2016 Honda Pilot on the highway approximately three weeks ago, we experienced a sudden, loud clunk from the engine, followed by catastrophic engine failure. The failure occurred unexpectedly while the vehicle was traveling at highway speed, creating a serious safety concern. Following the incident, we learned that the engine had suffered severe internal damage involving the connecting rod/piston assembly, with internal components breaking through the engine block. The vehicle now requires a complete engine replacement, estimated by the Honda dealership at approximately $20,000. At the time of failure, the vehicle had approximately 95,000–105,000 miles and had received regular maintenance at an authorized Honda dealership, including major engine maintenance in November 2025. We are particularly concerned because Honda previously issued Safety Recall 23V‑751 for connecting rod bearing failures affecting certain 2016 Honda Pilots. However, our vehicle’s VIN was excluded from that recall despite experiencing an apparently similar catastrophic engine failure. the federal safety agency also opened Investigation PE25008 to investigate additional connecting rod bearing failures involving Honda vehicles outside the original recall population. We believe our vehicle’s failure warrants investigation to determine whether it is related to the known connecting rod bearing defect and whether additional vehicles were improperly excluded from the original recall. We have opened a case with American Honda, which is currently reviewing our request for assistance with engine replacement. We request that the federal safety agency document and investigate this incident as a potential vehicle safety defect, given the sudden engine failure at highway speed and the risk of a serious accident.

The engine has developed a severe internal engine knocking/rattling noise while running. This symptom matches the defective crankshaft and connecting rod bearing failures detailed under the federal safety agency Campaign 23V751000, presenting a severe risk of sudden stalling and complete engine failure under load.

I am writing to report a severe internal engine defect on my 2016 Honda Pilot that poses a sudden stalling and safety hazard, identical to the failures covered under the federal safety agency Recall Campaign Number 23V‑751. My vehicle is currently experiencing a distinct metallic rattling/knocking noise coming from the lower engine block. This noise is highly noticeable under acceleration and high-load conditions right before the transmission shifts gears at higher RPMs. Upon performing an inspection of the engine oil system, the drained engine oil revealed a heavy concentration of microscopic metallic "glitter" and shimmering copper/silver shavings suspended in the fluid. This confirms acute, active connecting rod bearing degradation and crankshaft journal wear. Despite displaying the exact textbook symptoms, failures, and manufacturing characteristics of the defect outlined in Recall 23V‑751 (improperly ground crankshaft journals from the factory), my specific VIN is currently excluded from the recall scope. I am submitting this complaint to formally document that my vehicle is a clear positive match for this manufacturing defect. I request that my VIN be added to the active recall scope or included in the federal safety agency’s ongoing investigation regarding Honda’s under-inclusive recall volume, as this failure introduces an immediate risk of catastrophic engine seizure and sudden loss of motive power at highway speeds.

Driving home late Tuesday night October 13, 2026 the car made a severe noise, pulled to side of the road turned car off. The car would not start, the car was towed the next day to the Honda Dealership it was bought from. The car had just been in the Honda shop for routine maintenance. There was no warning lights. The safety concerns being on the side of a busy road. My wife and 2 children had to wake up and come and get me. This Pilot is our primary car the other one is not safe enough and is used for in town driving. According to the dealership it was towed to it was a P0304: cylinder 4 misfire misfire with a brand-new plug and a healthy timing belt, together with a loud engine noise, points to mechanical damage inside the engine. That fits a rod bearing failure.

Catastrophic internal engine mechanical failure. My 2016 Honda Pilot (3.5L V6 engine) has developed a severe connecting rod bearing knock that is highly audible during cold starts and heavily intensifies upon pressing the gas pedal to accelerate. This issue is an exact match to the mechanical defect and symptoms detailed in the federal safety agency Recall Campaign Number 23V751000 (Improperly ground crankshaft pins causing premature connecting rod bearing wear and engine seizure). However, when running my vehicle's 17-digit VIN, the system states that my vehicle is excluded from the recall list. This is a severe, life-threatening safety hazard. The engine is at immediate risk of throwing a rod, throwing metal debris into the oiling system, or completely seizing without warning, which would cause an abrupt loss of motive power at highway speeds or a catastrophic engine fire. Because thousands of owners outside the original production window are experiencing this identical failure, I am filing this complaint to urge the federal safety agency to mandate that Honda expand Recall 23V751000 to include all affected 3.5L V6 engine blocks.

very well maintained 2016 honda pilot oil changes done on time only 149k miles started it up labor day weekend to a sound of engine knock. It ran for a min or two before I turn it off oil was full. It is not the failed timing the belt tenisoner.... I called my local Honda dealership where they said my vin was not included in the crank/engine bearing recall. I have no warranty and the dealership of course wants me to tow it there to pay their tech their diagnostic fee. I have read so many stories of this happening to the honda pilot and Ridgeline vehicles. This is a shame.... Honda needs to step up & double check their manufacturer dates & add more vin to this recall ASAP

I was driving home from a road trip with my family of four, and I noticed that when I accelerated, the engine made a knocking noise. Prior to this, I had driven the car about 300 miles that day with no issues. While I was driving, my wife asked if we could record the noise so we could take it to a mechanic to diagnose the issue. While filming, I revved the engine a few times, and the noise would get really loud. After filming, I drove about 10 more miles, and the engine completely shut off. The check engine and oil lights both came on, and when I pressed the gas pedal, the car made a polite dinging noise. When the incident occurred, we were in the middle lane driving about 70 miles per hour. Knowing that I needed to get off the highway before I ran out of momentum, I carefully changed lanes and coasted off to the nearest exit. Thankfully, we were able to safely get off the highway and into a parking lot. Had we not, we would have been stuck in the middle of 70mph traffic potentially causing a high-speed collision. I was able to get the engine restarted, but it made a horrible squealing noise while running and a knocking noise when I revved the engine. The car also displayed an emissions check error, along with the oil and check engine lights still on. I had the car towed to an independent mechanic, who diagnosed it as catastrophic engine failure due to spun bearings. I did some research and found a recall for the defect, 23V‑751, but my car isn't covered in the initial campaign. I understand the federal safety agency is continuing an investigation into this defect as more cars, like mine, are reporting the same problem. As a result, I took it to the Honda dealer to get a Goodwill Repair, and they diagnosed the car with the same issue. Honda is not going to cover the repair, so I am left with a broken car because of their manufacturing defect.

I am a [XXX] female driver in northern [XXX], and I am driving a 2016 Honda Pilot that is suffering from severe, documented engine failure symptoms that Honda refuses to address. The vehicle is producing a distinct squeaking and chirping sound from the engine bay, and a recent inspection of my engine oil revealed magnetic metal flakes. This indicates that critical internal engine components — likely the connecting rod bearings or camshaft—are rapidly tearing themselves apart and grinding down into the oil stream. The Check Engine Light continuously comes and goes. When taken to the dealership, instead of diagnosing this severe mechanical hazard, the dealership completely neglected the issue, stated they did not know why it was happening, and simply cleared the light, sending me back out on the road in a ticking time bomb. Although my specific VIN is currently excluded from Honda's active rod bearing recall, my vehicle is exhibiting the exact textbook symptoms of the manufacturing defect currently under the federal safety agency investigation.

My 2016 Honda Pilot Elite has developed a loud, heavy metallic knocking sound coming from the engine block that increases in speed with engine RPMs. Despite strict regular maintenance and oil changes, the engine noise is getting progressively worse, creating an immediate risk of catastrophic engine failure, stalling, or seizing while driving on the highway. While this vehicle matches the exact failure symptoms of the federal safety agency Recall 23V751 for connecting rod bearing failure, my specific VIN is currently excluded from the recall scope. I am reporting this as part of the ongoing investigation into underreported V6 engine batches.
