Service Brakes Problems of Honda Passport - part 1

On numerous occasions while driving on the highway with no other vehicles in the vicinity of my vehicle the forward collision active braking activates aggressively and brakes for no reason this is concerning at 70 mph with a vehicle behind that may be following to close on a slippery road surface. Vehicle is available for inspection any time upon request. Vehicle has not been inspected by any one yet. No warning lamps other than the one associated with forward collision braking.

Purchased car new. Problems with brake system started at 6k mls. Problems got progressively worse to 29k mls where now rotors are being replaced due to “extreme warping” with pads, calibers, and everything else deemed fine. On brief internet search it was apparent that this rotor warping at low milage is a common problem. Warped rotors are a safety hazard to the driver, their passengers, and everyone else on the road with them. Please investigate.

I have had my rotors turned 3 times and replaced once in the span of 2 years. They are warped each time, causing pulsing in the front end when braking. My brake pads have never needed to be replaced. I was told by the mechanic that taking a road trip puts a lot of strain on the rotors and overheats them. I am finding this is a common issue for many other owners of this vehicle. Mine has 27k miles on it. The first 3 times the car was in for having the rotors turned was within the first 6 months of ownership, under 10k miles, and I am the only owner.

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

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.

The brake system is not working properly when stopped on a hill. The vehicle will roll backwards after pushing the brake. If you are stopped on a hill you have to keep the brake engaged while also accelerating to keep from rolling backwards and hitting the car behind you.

The cmbs alerts braking despite there being no obstacles in front or around the vehicle. Also, the at stop lights when the engine shuts off, on several occasions the car has completely turned off and will not let you do anything (place in park or drive) until you manually start it again.

While driving and pressing on gas the car started beeping and started to brake. There was no obstruction in front of me to cause this. The break flashing signal didn’t come on. It just beeped and started to brake and then stopped.

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.

The contact owns a 2026 Honda Passport. The contact stated while driving at various speeds, the brakes were independently activated briefly, with the message “brake” displayed. There was no warning light illuminated. The local dealer was contacted; however, the vehicle was not diagnosed or repaired. The contact was informed that the VIN was not under recall. The manufacturer was not notified of the failure. The approximate failure mileage was 8,637.

Incident # 1. June 2025 vehicle has approximately 3400 miles on it. I was driving southbound on I 35 freeway in the lakeville minnesota area. I was in the center lane of the freeway traveling at about 65 mph. Traffic was light. There was no one in front of me. Suddenly, the car broke hard. I was thrust forward against the seatbelt with my hands, pushing against the steering wheel as the car slowed rapidly and came to an abrupt stop from 65 miles an hour. I had no ability to get the car to go. The gas pedal had no effect as this car came to a rapid stop. I found myself stopped in the center lane of the freeway frantically looking around to see what cars were coming, can I find the four way flashers. A car passed me in the right lane and a car passed me in the left lane. Then I was able to limp over to the shoulder out of the traffic lanes. I shut the car off immediately and tried to compose myself. After a moment or two, I turned the engine back on and the car operated normally. At the dealership they fixed some things but they said they didn’t find anything that was directly related to the unexpected rapid braking. Incident #2. July 2025 vehicle has approximately 4300 miles I was driving northbound on 35e taking the entrance ramp to eastbound highway 36. I was driving on the entrance ramp beginning to accelerate to highway speed. There were no vehicles in front of me, not on the ramp, or on the highway. As I neared the end of the ramp the vehicle suddenly broke hard thrusting me forward again. It came to a complete stop. Fortunately, for the second time, there was no one behind me. This was the second time the vehicle engaged the brakes in an emergency stop for no reason. The dealership said they couldn’t find anything cause of the incident. The vehicle remains at the dealership. I have requested reimbursement of my purchase price from Honda. We have an arbitration hearing schedlued on oct 27, 2025.

Concerns with the brake master cylinder and brake booster. Bolts not torqued enough during manufacturing. I had an independent inspection completed on 6/4/25. Technician determined the bolts were not torqued properly. Concern is my brakes could fail causing fatal crash.

On 11 Apr 2025, I was driving my 2023 Honda Passport at night on a toll road in clear weather when my infant son began screaming in distress. I pulled over onto the shoulder, partially onto a dirt area with bushes for more space. I pressed the “park” button, unbuckled my seatbelt, and opened the driver door to step out. As I did, the vehicle suddenly began rolling forward despite being in park with the door open and the seatbelt off. I fell trying to exit and had to roll away from the vehicle as it continued moving. A passenger jumped into the front seat and stopped it. This wasn’t a lurch or slight movement the car rolled enough to put me in danger. It behaved as if it were in neutral, not park. I later tested the same conditions (engine running, door open, seatbelt off), and the vehicle auto-shifted to park as designed. This confirms the safety feature failed in that moment. No warning lights, alerts, or error messages appeared before or during the incident. I reported the issue to Honda and asked the dealer to inspect the transmission and interlock systems. No faults or diagnostic codes were found. The service advisor said park can take a second to engage, but the movement I experienced was excessive and unsafe. This is a serious safety concern, especially with children in the car. I’ve also seen other reports of similar issues in Passport and pilot forums. I have manageable scrapes and a joint effusion in my knee.

The vehicle infotainment system froze. Several minutes later after driving, I pressed the brakes but they did not function. The vehicle would not stop and crashed into the vehicle in front of me. Emergency braking did not engage or otherwise show signs of activation. After turning off the car and dealing with the accident, I restarted the vehicle and the brakes and infotainment system operated normally.

This afternoon traveling home from our 5 year olds swim class, turning into our neighborhood at appropriate speed and braking. Shortly after I turned in, my Passport jerked, dinged, locked the steering and then was ok. No error lights came on but was very scary. Too many recalls with this vehicle.

I have a 2024 Passport black edition that has had front brake rotor issues since about 4k miles. It has has struts, wheel hubs, bearings, brake pads rotors either replaced or resurfaces 4 times and I am afraid to drive the vehicle at this point. Its been parked since oct 2025 after the last repair while I fight with Honda to take the vehicle back .

We are currently experiencing very cold weather in my area. I have a Honda Passport that uses a camera for its braking, lkas, acc, and other features. During extreme cold, the camera shorts out causing safety systems to fail. Others report the same issue on Honda cars: [xxx] no accident or injury resulted - merely trying to avoid a future safety issue information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Rotors went bad with less than 250 miles on new car. Per american Honda rotors are not defective, because dealership didn't day were defective; therefore, not covered under warranty, considered wear and tear. Dealership initially stated the cause of the rotors going bad was that I was hard braking and riding the brakes; however, first, I'd only had the car about 3 months and second, I contacted the dealership a few days after I bought the car and informed them of the problem. Next, dealership said the rotors were bad because my aftermarket floor mats were resting on the brake; however, the mats were put there two days before. The 2024 Honda Passport rotors are defective. At the very least the rotors in the one I purchased are dedective.

Breaking and steering wheel malfunction causing accident on December 20th 2024. Car is currently still at dealership for investigation. My safety was at risk, causing injury to shoulder. Not sure if problem has been reproduced, not confirmed by dealership as of yet. Police reported, insurance company only fix damage, then vehicle was towed back to dealership for inspection, after being repaired in a different shop. Was called back by dealership to have additional inspection done and was told that my car was going to be refurbished. Issues started once my car had hit 10,000 miles, after my first vehicle maintenance expectation. Received multiple systems warning lights, information dealership multiple times and nothing was done until after the accident still have no car til this day 5/14/25.

The automatic braking system will activate at various times shaking the wheel and applying the brakes. This happens when there is nothing in front of the vehicle.

On Nov 9, 2024 I was pulling into a parking spot in a public parking garage, after turning 2 tight corners to approach the parking spot. About half way into the parking spot, the car suddenly lurched and accelerated and I crashed into a 90 degree concrete corner wall! it happened so fast, without any warning sounds or abs brakes deploying. The entire front passenger corner of my car was badly damaged. Luckily I was not injured, nor were there any other vehicles or persons involved. It is just not possible that I could have personally pulled into a parking spot at such a high speed as to cause such extreme damage to the vehicle! I drove the vehicle to a body shop on 11/11/24, which was one recommended by my insurance company. The vehicle was inspected by the body shop, which was directly in contact with my insurance company. I did ask the shop to make sure the mechanic checked for any safety issues during repair, as I was concerned as to the cause of the accident. I have an impeccable driving record and I cannot explain how such an accident could happen! I had no issues with the car previously. Upon further inspection into the damage, on 1/3/25 it was finally evaluated as a total loss, as there was damage to the frame and other issues! I did receive a statement on 1/3/25 from the body shop that there was a "fault in the system, causing gas pedal lock, which might be cause of accident". I felt I had to report this possible issue that resulted in a total loss and obviously could have injured myself, others or other vehicles!.

Emergency braking system activated for no apparent reason. Traveling at freeway speeds on a straight section of freeway when braking system briefly activated. There were no other vehicles or obstructions within 200yrds that might have triggered this. Had someone else been driving or if we had been in rain or snow conditions the outcome might have been different. Vehicle was approx 3 days old when this happened and brought back to the dealer to check. They could not reproduce. There were no prior symptoms or warning lamps.

The automatic emergency braking system engages in times when it is not appropriate to do so. The vehicle will flash the “brake” warning light on the dashboard, will shake the steering wheel, apply light braking, and in a few instances has applied hard braking. We have been unable to determine a specific trigger for this issue. The vehicle will engage this feature on strait roads with no other vehicles or obstructions on the road. It has happened during both rainy and sunny conditions. The vehicle has also exhibited this behavior when going up and down hills both with and without other vehicles present. The vehicle will do this sometimes when other vehicles enter our lane at a safe distance and at low speeds, at or below 30 mph. The vehicle has also done this at highway speeds of 55+ mph both with and without other vehicles or obstructions in the roadway. We have experienced this while driving curvy roads both with vehicles passing in the opposite lane of traffic and when no other vehicles are present. The feature appears to randomly engage at all speeds between 15+ mph to 70+ mph with or without vehicles on the roadway. It also doesn’t appear to matter if a vehicle is in our lane, an adjacent lane, or the opposite lane of traffic. This issue was identified and has been ongoing since the vehicle was purchased in October 2023. The issue happens at least 1 time most days the vehicle is driven but can range between 1 time and 3+ times each day. The vehicle is driven consistently 30+ miles each day with occasional trips of 300-500 miles in a single day. The other issue we have noticed is the rear cross traffic warning. We have noticed something’s this will engage when no other traffic or obstacles are present. We have also observed this feature failing to engage when a vehicle or obstacle is present. This issue does not happen often but has been observed enough that is has come to my attention as a potential issue.

I purchased this vehicle from a dealership 1 week ago. Prior to receiving the vehicle it had been serviced by the dealership and had passed inspection. The vehicle is a 2021 with low miles and appeared to be in very good condition with no appreciable rust, corrosion or wear. Since purchase, I have driven the vehicle about 160 miles on my daily commute. I did have issues with one of the automatic systems, but will submit that as a separate report as I do not believe it is related to this issue. Tonight I was driving home from work on a hilly, curved two-lane road and came upon a vehicle parked across the opposite lane and slightly into my lane. I was traveling at about 45 mph and pressed on the brakes suddenly but with reasonable force in order to slow to pass with caution. I immediately felt loss of brake pressure and did not stop as expected. I continued on at the same speed and passed very close to the rear of the stopped vehicle. Fortunately, I was able to swerve to avoid a collision. Once the brake pedal was pressed completely to the floor, the vehicle began to decelerate gradually as I continued down the hill. No warning lights or alerts came on at that point. At the bottom of the hill, I turned onto a flat quiet road to drive slowly and assess the situation. I determined that the brakes were compromised and that most pressure had been lost. I parked the vehicle and about 15 minutes later turned it off and back on and numerous warning systems came on saying that the brake fluid was low and other steering and traction control systems were compromised. I got out of the vehicle and brake fluid was pooled on the ground by the rear tire on the driver's side. When the roadside assistance person arrived we confirmed the leak by putting more brake fluid in, which gushed out onto the ground when the brakes were applied. The vehicle was transported by flatbed to a repair shop. There was no warning prior to this incident and no emergency system alert until well after.

The automatic emergency brake system will randomly activate despite there being nothing in the way, no car in front, and no obstruction. It causes the car to slam on the brakes for no reason which I’m afraid will cause someone to hit me from behind.

The brake and tmps ights came on for no reason while driving. I pulled over to the side of the road in fear of my safety. I restarted the car to see if they would clear but unfortunately they did not. The manifold and gasket were leaking. The vehicle has been misfiring.

The vehicle has made multiple abrupt emergency brake activations in non-emergyncy situations. Nearly causing a crash multiple times. It's my opinion this system is severely flawed and extremely dangerous - not only to me but anyone around me. Shame on Honda for allowing this system to drive on our roads.

Driving on 684 in new york state and the car started to break and no objects or cars in front of us. Dash-broad light came on and it said break. Traveling doing 70 mph and car went to 50 or so in seconds. This goes on about once a week in different areas.

I have encountered two types of brake issues: 1) my vehicle seems to flash brake occasionally when oncoming vehicles pass by for no reason - they are not entering my lane or doing anything that should cause the message to flash. The vehicle type does not seem to matter - they have been old and new models, and have been both cars and trucks. My vehicle has only visually warned, but does not engage brakes, so no further safety issue is involved. It has done it frequently on some days and then none for awhile. We have tried to make note of vehicle type and model for consistency, but have not found any. 2) if my vehicle has its cruise control on (which is often) and a vehicle in front of me moves into a left-turn lane to turn - often with plenty of notice - my vehicle will engage it’s brakes and slow down even though there is no danger of hitting the other vehicle. So long as I take it out of cruise control, it will continue on driving. I suspect that if cruise control is not disengaged, it could fully brake and cause a bigger issue of an injury or accident.

The Passport flashes brake and steering wheel shakes for no reason. I’ll be driving down the road nothing near and it does this. A few times it’s actually applied the brakes. Thank goodness no one was behind me as it potentially could have caused an accident. This occurs daily. Especially if I am driving on a 2 lane road.

On Sunday April 14 while driving on the lie middle lane a person driving at a high speed went from right side across to left lane in front of me when all of a sudden the brakes activated itself and my car nearly came to a stop nearly causing a car behind me to rear end me. This happened several times before while driving approaching vehicles in front scaring my family and I. Now my cmbs lights are permanently on on the dash. This system is nerve racking and will cause a severe fatal crash. Many people on several platforms are complaining about the same or similar issues. And understand an investigation has begun. Something needs to be done to resolve this issue. I have owned my 2021 Honda Passport since November of 2023. With 19k miles.

The collision mitigation braking system (cmbs) comes on randomly with no vehicles or obstructions in front of it.

No warning messages on dashboard. The drivers side mirror goes off like there's something there but there's nothing. Same with the braking display light comes on when I'm no where near anything, yet I've had cars pull out in front of me thankful no crash has happened because it doesn't go off then. I plan to take it into the dealership soon. I can't give an estimate of how long exactly it's been doing this. Especially side mirror warning. That's been going on. The braking thing has probably been a month now.

When driving the auto breaking is applied. The warning system flashes on the dash and the breaks are applied, there are no cars around me at the time. The system will also activate at times when going around a curve and a vehicle is approaching from the opposite direction.
