2016 Honda Pilot engine problems

Filed Nov 5, 2026 · Engine, Fuel system · AZ

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.

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.

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.

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.

I have been having issues with my 2016 Honda Pilot and I looked on Experian and it stated that there is a recall. There are two different recalls, the first one says Fuel Injector/W Software Update the date is 11/24/2020 and recall # W8V. Also recall for Start/Stop Switch that the recall date was 12/9/2020 and recall # Y93. I bought my car in 2024 but I did not get an extended warranty. The car is having same symptoms for the past 2 years, my husband tries to fix what he can. Even though it is not under warranty they never fixed these issues before selling my car. It started acting up after 3 months of having it. So I am thinking they just took of the system problem and tweaked it so the car would be sold.

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.

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.
