2021 Honda Passport

My 2021 Honda Passport Elite suffered cataphoric engine failure at 90,000 miles. The 6th cylinder bearing was missing when my vehicle was towed into Honda for diagnosis after my engine shut off while I was traveling 55 mph. I had no warnings for this failure including no engine noises and no check engine lights. I had to have a new engine put in my vehicle and Honda refused to cover the cost at 100% because they stated there were no open recalls at this time. I feel this is a manufacturer engine defect that is the same as the open recall defect Honda has on the 2017, 2018, and 2019 Pilots with the same 3.5-liter V6. The engine failure descriptions are exactly the same.

Fuel Injectors/ Misfires

The CMBS malfunction lights come on every time I start my car. The only time it went off was when I drove straight for about 15 minutes without stopping at a light It started a few months ago out of nowhere. I thought it was my camera, I took it to a Honda dealer and they said I needed to buy another camera for 2500 dollars. I don't have 2500 dollars they told me I could drive it but I won't have that safety feature. I only had this car 6 months and already the camera is acting up. Another dealer said it could be the battery. I really don't know why at this point that everyone is having these issues with the Honda sensing camera. I think it is a safety issue because it should be working at all times

Driving to work in normal speeds and conditions. The emergency braking enabled and slammed on the brakes to my car - despite there being no threat or need. The brake was with such force that I jerked forward. This is the third time this has happened with this car in the past week. Car is available for inspection if needed. The car has not yet been inspected by Honda for this situation.

I bought my car in 2021. Two weeks ago 4-5 dashboard signs came up on my screen. I contacted local dealer and they said they need nearly $3000 to fix it. I told them it’s a safety issue and they refused to budge. I complained to Honda through X and they refused to help me. They are not taking it seriously

I purchased a used 2021 Passport the end of May 2025. While driving, the 'collision mitigation braking system' or CMBS would activate the braking system and would intermittently just brake, causing panic for not only myself, but I'm sure drivers behind me for suddenly braking with no imminent threat in from of me. This happened multiple times without receiving any warning or notifications, just suddenly. It would happen without warning, or sometimes nearing a bridge or a cover plate on the road, which almost caused accidents multiple times to get rear ended. I have driven for decades and never felt anxiety until I drove this vehicle for a few months. I felt scared driving this vehicle, feeling uncertain when it would suddenly just brake. Eventually after a few months of driving, I got a reading that said CMBS problem on the screen. I scheduled an appointment with the dealer. The dealer suggested a near $3000 replacement for a camera (on a 2021 vehicle). At the appointment, I ultimately returned this vehicle to the dealer where I bought it and unfortunately lost out on thousands of dollars after having the vehicle about 6 months. I have always liked Honda, and have had 2 prior Hondas, but with this vehicle purchase, I felt the most unsafe I have ever felt in a vehicle, and moving forward will not feel comfortable purchasing Honda.

After having constant issues with the idle stop and the car alarm going off in the middle of the night and day for no apparent reason I took it to the dealer to get it fixed. After supposedly fixing the idle stop, about two weeks later I was going up a ramp during a heavy traffic hour and the car completely shot down. It took me a few minutes to get it back on. I’ve had issues with this car from day one (brand new). I’m currently trying to get another car.

During an oil change my magnetic drain plug was caked with magnetic gray material with specks of silver flake in it. This oil change has 6142 miles on it. I am concerned because my passport was built in Sept of 2020 right at the transition of the previously recalled j35 motors were produced. Car has been serviced at the Honda dealer since new except last 2 oil changes which were performed by me.

Auto idle malfunctioned. At a stop light the engine turned off and it took 5 minutes to restart the engine. No warning lights or messages appeared before it happened. Had the PGM-Fl Idle stop software update done 9/16/23 at 17,582 miles. Took to dealer they could not re create , the car has 46,359 miles now. This is 2nd vehicle this has happened to me , other vehicle same exact auto idle problem started at 60,000 and I drove it for 13,000 miles experiencing stalling out at lights and in stop and go traffic for over a year ( very dangerous and scary experience ) I took it to 2 different Honda dealers numerous times before they finally replaced starter assembly , starter relays and adjusted the valves per the March 2023 warranty extension notice .

One day the lights just started flashing. Took to dealer and was told that someone must have backed into me and would be about $2500 to replace the camera (which is behind the windshield). Occasionally it will function but clearly seems to be a malfunction. In research online there appear to be many others that have experienced the same issue - can’t just be a coincidence. Shouldn’t happen on a reliable four/five year old car

WHEN ATTEMPTING TO MERGE ONTO A SECONDARY ROAD AFTER EXITING THE INTERSTATE ENGINE POWER WASNT THERE AND THE CAR FELT AS IT WAS GOING TO EVENTUALLY JUST DIE. THIS HAPPENED WHEN THE CAR HAD BEEN DRIVEN OVER 50 MILES, SO IT WAS AT OPERATING TEMP.. REMOVING FOOT OFF THE THROTTLE AND REALPPLYING SEVERAL TIMES HAD THE CAR RETURN TO FULL POWER. LUCKILY, FOR THIS INCIDENT, TRAFFIC WAS LIGHT AND THE MERGE LANE WAS LONG. SO FAR THIS HAS OCCURED TWICE IN THE MONTYH OF JANUARY 2026.

During a winter storm in approximately 10°F weather, my vehicle became immobilized due to a no-start condition. The starter initially engaged and cranked the engine several times, then failed and would only free-spin without turning the engine. After this occurred, the vehicle could not be shifted into neutral because it is equipped with an electronic shift-by-wire transmission. The only method to move the vehicle requires a proprietary Honda mechanical neutral-release tool (07AAA-TZ3A100). This tool was not supplied with the vehicle, was not available to the owner or responding tow operators, costs over $200, and local Honda dealerships do not carry it in stock. As a result, it was not possible to obtain the tool in an emergency situation. Two flatbed tow trucks responded. Both operators stated the only way to load the vehicle would be to drag it while locked in park, which would likely cause damage to the transmission, drivetrain, or tires. This was not a safe or acceptable option. As a result, occupants were stranded from approximately 1:00 PM until 6:30 PM in 10°F weather with no heat, because the vehicle could not be moved. A single common mechanical failure should not render a vehicle completely immobile with no accessible emergency override. Requiring a costly, proprietary tool that is not provided with the vehicle and not available to dealers or emergency responders creates a serious safety risk due to cold exposure and inability to move or clear the vehicle during emergency conditions.

Was driving 47 mph at 12:35 EST on a clear sunny day and car braked automatically. No car in front of me.

During a normal drive we came to a stoplight, seconds after stopping, an emissions alert displayed along with transmission and VSA (I think). Upon seeing these codes I began to drive into a gas station and the vehicle barely moved with little power. We were able to park about 40 feet away and the vehicle would not move any further. This sounds similar to the existing recall but this model year is not included. I had to have the vehicle towed.

Vehicle has been having AIS issues for a couple of years, requiring new batteries, new starter/relays and countless internal computer updates (none of which have helped btw...). This morning she had the AIS engaged, went to turn left at a green light and when she released the brake the vehicle threw itself into Neutral and flashed a "Auto Idle Stop System Problem" message on the dash. She put it into park and tried to restart, which failed, she then had to turn the vehicle off completely and restart from there. As I mentioned, none of the computer updates Honda has done for this vehicle have helped and it's my understanding there is a block of vehicles in this age range (all Passports, Ridgelines and Pilots) that continue to have problems with the AIS as well. Honda needs to disable this "feature" on any vehicles they cannot fix via computer updates IMMEDIATELY before they get someone killed. Not to mention, we are sick and tired of having to replace the battery and/or starter every couple of years. Honda should not be putting tax breaks above their customers safety and satisfaction. You know it's bad when their 30+ year techs go out of their way to buy a used Honda just to avoid the AIS because they don't know what to do with it at this point either.

SRS warning light came on. Diagnostic found Code U3000-49 Internal Failure of the SRS unit-Seat weight sensors on front passenger seat Front seat lower frame/rail required replacement and was completed by the dealer at my out of pocket cost. This vehicle was not included in the Honda 750,000 vehicle recall for this same defect. Reference Notice 24-050

Car slammed on brakes while on interstate, the system likes to say brake, brake, brake, when there is nothing to brake for but a few days ago it actually took action and slammed on brakes on the freeway.

The contact owns a 2021 Honda Passport. The contact stated that while depressing the accelerator pedal, there was an abnormal sound coming from the vehicle. In addition, the vehicle vibrated abnormally and drove roughly. No warning light was illuminated. The vehicle was taken to an independent mechanic, but was not diagnosed or repaired. The vehicle was taken to the dealer, where it was diagnosed, and determined that the high-pressure fuel pump had failed and needed to be replaced. The dealer suggested that the fuel injector and throttle body needed to be cleaned; however, the vehicle was not diagnosed or repaired due to the cost. The contact related the failure to NHTSA Campaign Number: 23V858000 (FUEL SYSTEM, GASOLINE); however, the VIN was not included in the recall. The manufacturer was made aware of the failure. The failure mileage was approximately 140,000.

No incident has occurred. However, my concern is that a recall was issued on February 1, 2024 (NHTSA Recall Number 24V-064), and as of October 31, 2025, Honda is still stating that parts are not available to complete the repair. I first contacted Honda in March 2025—over a year after the recall was issued—and was informed that the necessary parts were still unavailable. I called again in October 2025, and received the same response. We are now approaching two years since this recall was announced, and it is unacceptable and inexcusable that Honda has yet to provide the parts needed to correct this safety issue.

The contact owns a 2021 Honda Passport. The contact stated that upon starting the vehicle, there was an abnormal knocking sound coming from the engine compartment. The check engine warning light was illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the connecting rod bearing in cylinder #3, resulting in damage to the engine. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 23V751000 (Engine and Engine Cooling); however, 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 73,000.
