2023 Honda Passport Brakes Problems

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.

This has happened 7 times since I have owned the car (purchased April 2023). On regular asphalt roads in clear daytime weather with no cars in front of me (and usually no cars behind), the emergency braking system goes nuts and slams on the brakes and the wheel starts shaking. The roads have never been wet, and there has never been debris or other objects around; I live in a semi-rural area with no curbs, guardrails or other close peripheral objects that could confuse the system. It's bad enough that the front rotors became warped and I had to replace them or deal with rumbling brakes. It also almost caused an accident the one time there WAS someone behind me, as they almost rear-ended my vehicle. Fortunately, that driver was paying attention. I would take the vehicle back if it didn't have 11k miles on it already. Having your vehicle suddenly stop completely out of your control on the highway is going to get someone killed. Hopefully not me!

The contact owned a 2023 Honda Passport. The contact stated that while driving approximately 70 MPH, there was a loud booming sound coming from the passenger’s side front of the vehicle nearby the wheel. The contact lost control of the vehicle, and the brakes failed to stop the vehicle immediately. The contact coasted to the side of the road where the vehicle eventually came to a stop. There were no warning lights illuminated. The vehicle was taken to the dealer who stated that the caliper bolt had detached causing the caliber to fall onto the wheel from the caliper mount. The dealer stated that the bolt was not initially installed correctly during the manufacturing of the vehicle. The vehicle was grounded. The manufacturer was made aware of the failure and opened a case. The approximate failure mileage 8,500.

The contact owns a 2023 Honda Passport. The contact stated that while driving approximately 70 MPH, the brake pedal was depressed; however, the vehicle was shimmying and rattling abnormally. The brake pedal was depressed but the vehicle was slow to respond. There were no warning lights illuminated. The vehicle was taken to the local dealer to be test driven. The contact was informed that the rotors were warped. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 22. The VIN was not available.

Twice I had all kinds of safety alerts were scrolling on May 2nd ans august 7th.. First it was a fluid leak and cable. Second there was a piece of metal in the brakes. ABS sensor full of grease. Now sometimes Brakes is flashing for no reason (like going uphill) and if I need to brake at a higher speed on the freeway, the brakes make a sound of pots and pans rattling. As I have no confidence in the brakes, I tried downshifting but the car speeds up. From time to time the car speeds up or slows down without any reason as I am not using cruise control. Forward collision warning does not work properly, in fact collision mitigation system is not fiable. I get a warning sign for the back seats when there is nobody and nothing on the seats. Everything is very irregular.
