Honda Passport knocking problems

Filed Oct 9, 2026 · Engine · OH

I have a 2020 Honda passport elite with a 3.5L V6 J35Y6 with 108k miles on it which is similar to the engines that have been recalled in other models like the pilot, ridgeline, and odyssey, and I have researched multiple vehicles with a similar problem of spun rod bearings which has left metal debris in my engine. I have found hundreds of passports that have been reported with the same issue. My vehicle is currently sitting at the dealership and they said it needs a new engine due to this issue. My vehicle is not drivable until the engine is replaced. The dealership estimated a cost of over $5k.

The vehicle experienced a sudden internal mechanical failure while driving, resulting in loss of propulsion and complete engine failure. The vehicle was towed to an authorized franchised dealership service center (Gardena Honda) for inspection. No check engine lights, warning lights or any pile pressure warning! Oil change was 2,500 miles until next service. Upon complete teardown and diagnostic inspection, factory-certified technicians confirmed internal engine damage, specifically connecting rod bearing failure leading to a seized engine requiring a complete engine replacement ($9,375.00 total repair cost). This internal failure presents a severe safety hazard: an unexpected engine stall or lockup at highway speeds risks loss of power steering, loss of power brakes, and an immediate crash. Symptoms align directly with the federal safety agency Recall 23V‑751 and ongoing federal investigations regarding Honda 3.5L V6 engine connecting rod bearing failures, where out-of-spec manufacturing leads to premature bearing wear and sudden engine seizure. The vehicle is maintained according to manufacturer specifications and has 55,649 miles. The failed components remain preserved at the dealership service department for federal or manufacturer inspection upon request.

I purchased the 2023 Honda Passport used with 47,500ish miles. It came with a factory 60,000 5-year powertrain warranty. The ONLY reason i paid cash for this vehicle. At 49,900 miles, the engine developed a subtle engine knock. At 50,460 miles, engine has clearly audible knock at idle - 2,000 RPM in gear (under load). 9/1/26 Antrim Honda, [XXX] denied hearing obvious noise. They did not collect oil or oil filter but charged a $190.00 diagnosis fee. The dealer’s conclusion: the noise is a “common engine characteristic of the 3.5" but is contradicted by the presence of bearing material in the oil. With 1,000 remaining on the previous oil change, completed by Keystone Ford, prior to my purchase, XXX, I changed the oil myself. I changed it into a new, cleaned pan, inspected and found heavy metallic “gold dust” bearing material suspended in the used oil. I have retained both the used oil and the oil filter for Honda’s inspection and independent laboratory analysis. No warning lights or codes on the dash.

The engine experienced a catastrophic lower-end bearing failure at approximately 63,000 miles. The vehicle had been maintained according to the manufacturer's recommended maintenance schedule at the dealership service department. There were no missed oil changes. The failure occurred without any prior indication that a major internal engine problem was developing. The vehicle was taken to a Honda dealership, where the engine was disassembled. The dealer confirmed a lower-end bearing failure and reported significant metal debris inside the engine. The engine was determined to require complete replacement. A sudden internal engine failure creates the risk of an unexpected loss of power while driving, which can increase the risk of a crash, especially in traffic or at highway speeds. The failed engine is available for inspection through the servicing dealership if requested. The failure has been confirmed by the Honda dealership. No warning lamps or messages provided sufficient advance notice to prevent the failure beyond symptoms associated with the engine failure itself. I am submitting this report because I believe this may represent a manufacturing or design defect rather than normal wear and tear. I request that the federal safety agency investigate whether similar connecting rod bearing failures are occurring in other Honda Passport vehicles with this engine.

The vehicle experienced a catastrophic internal engine failure caused by connecting rod bearing failure. Prior to the failure, the engine developed abnormal internal knocking/noise, indicating bearing deterioration. The engine is currently available for inspection. While traveling approximately 55 mph on [XXX], the check engine warning light illuminated. Within about one mile, the engine rapidly lost power and developed a severe knocking noise. The sudden loss of power at highway speed created a serious safety hazard by reducing my ability to maintain traffic speed and safely maneuver the vehicle. I had my child in the vehicle, and both we and surrounding motorists were placed at risk of a collision while I attempted to move to exit traffic. The failure has been confirmed by an independent repair facility, Absolute Automotive LLC in Parker, Colorado. Their inspection determined the engine suffered internal damage due to connecting rod bearing failure. I have the engine replacement invoice, technician's diagnostic notes, and photographs documenting the engine damage. The vehicle has not been inspected by Honda. I contacted Honda to report the failure and request assistance, but I was informed there was no recall for the 2021 Honda Passport equipped with the 3.5L V6 engine and that Honda would not provide assistance unless a recall existed. Before the engine failed completely, the engine developed abnormal internal knocking/noise. While driving on [XXX], the check engine warning light illuminated, and within approximately one mile the engine lost power and produced a heavy knocking noise, rendering the vehicle unsafe to operate. I am submitting this complaint because a sudden internal engine failure resulting in loss of power at highway speeds presents a significant safety hazard and should be investigated.

I took my card to Honda Of Staten Island. An advisor took a ride in my car and heard the knocking noise from under the Honda Passport. He asked to have the car be put on a lift to make sure there was nothing dangerous with the passport, after it was checked by a mechanic, they said it was safe to drive, the noise has become louder. I checked on Honda's website with my Vin, and nothing comes up on recall, however when I look with my model, year it says Rr Subframe bolt. I am hoping that Honda does not say they can't find anything wrong when I clearly hear the noise Honda's website is describing. I thought I inform the federal safety agency about this. I don't want to get into an accident or for that matter anyone else because of this issue.

Engine failed and now the piston rod is knocking inside the engine. Engine failure while operating a vehicle is extremely dangerous and could cause an accident or death to myself and anyone else around my vehicle while its being operated. This type of issue can even cause a fire in the engine bay. When the issue presented itself I was going 60 down the highway. Yes, the vehicle has been in two independent shops which have both confirmed the engine failure due to premature connecting rod bearing wear which was most likely caused by manufacturer crankshaft issues. No it has not been inspected by manufacturer, police, insurance, or others. No there were not any warning lights, messages, or sysmptoms prior to the failure.

While driving at highway speeds, I experienced multiple loud, intermittent double-knocking noises within a short period of time, followed by an additional grinding/rotational noise at low speeds. These noises were abnormal and raised immediate safety concerns, prompting me to bring the vehicle to a dealer that day. During inspection and test driving, the noise condition was confirmed. Further inspection revealed that a front brake caliper (flange) bolt was missing, and the brake caliper had shifted out of position. This bolt is a critical fastener that secures the brake caliper to the brake assembly and is available for inspection through service records. This condition posed a serious safety risk, as a shifted or unsecured brake caliper could result in reduced braking performance, brake failure, or wheel lock-up, potentially endangering vehicle occupants and other road users. The issue was confirmed by an authorized Honda service center, and the vehicle was inspected by manufacturer-authorized personnel. The vehicle was repaired at no charge by reinstalling the correct hardware and restoring the brake caliper to its proper position. One week later, I have come to find out this is a known issue, and Honda has issued a Technical Service Bulletin (TSB) for 2023–2024 Honda Passport vehicles addressing loose or missing front brake caliper/flange bolts. I never received a recall notice or voluntary letter from Honda notifying me this might be an issue or to have it inspected. No warning lights or messages appeared prior to the incident; the only symptoms were the knocking noises at highway speeds and grinding noise at low speed.
