Was driving through highway construction site. One lane, jersey walls close on both sides. A lane shift was forced by the jersey walls and my vehicle slammed the brakes causing me to need to very accurately control steering during this unnecessary emergency braking situation. Cars behind me had no way to drive around or a shoulder for an out. Traffic was heavy, lucky that no accident occurred. Other less dramatic events have occurred with the auto braking as well. The front collision warning without auto-braking occurs on nearly every drive.

Problem started at 11,000 miles as very minor and has become progressively worse up to the now 32,000. Vehicle has been to dealerships 5 times with no repair performed. THE MAJOR SAFETY ISSUE: Hesitation and gear searching on acceleration. Intermittent acuity. 3 times I needed to accelerate quickly in order to merge with 40 mph traffic from a stop sign. I stepped on the throttle and the vehicle lurched into traffic then lost power and gear searched for 3 seconds creating a potentially very serious incident. Once the gear engaged, the vehicle took off at a high rate of acceleration and speed causing yet another unsafe condition and making me look like a maniac. THE OTHER SYMPTOMS: 1) Hard Starting, sometimes vehicle seems to sputter, sometimes it revs hard on startup 2) Vehicle sometimes enters some kind of error state similar to the vehicle not being in park when the engine is shut down. An audible alarm sounds, like when the lights are left on or a key is left in the car, and the vehicle refuses to lock the doors on its own as usual. Visual inspection by the driver reveals nothing appears to be wrong. Lights are off, no key left, vehicle is in park. Powering back on, checking park indicator and turning back off seems to reset this condition. 3) Inconsistent accelerator pedal input. Sometimes the vehicle goes much harder or seems to be held back by something at other times. 4) Erratic torque distribution for AWD. Viewed from dash torque distribution readout. AWD engages 100% at all wheels at times of very light throttle on dry pavement. 5) Engine just sounds terrible at idle and at times of hard acceleration. 6) Rough acceleration. Choppy gear shifts. 7) Vehicle continues to push forward under power when throttle is lifted and brakes are applied causing harder than usual brake pedal pressure to be necessary and inconsistent vehicle slowing. 8) No CEL is on. 9) Constant minor weaving due to inconsistent AWD torque delivery.

The push button gearshifting. I have accidentally hit reverse about 100 times since I’ve owned this car in six months. It ended up in a rear end collision with a parked car. Then when I tried to drive forward, I backed up again. The first time was intentional backing and I didn’t see the car behind me… the second time I was attempting to drive forward and I hit the reverse button again. It was instinctual. I hit the car twice.

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.

my 2023 Honda passport is having shifting problems (high revs, slow nd unpredictable power to wheels) harsh acceleration (not easy to safely /smoothly gauge power and speed from acceleration to wheel) high revs "stuck" --not shifting down smoothly/safely These issues are on going. I also researched and saw this has been reported b y other Honda Passport( 2023) owners. I contacted dealer 10/16/25 to document the complaint and asked dealer to call me back if any service advisories or recalls, they said no, but a service advisor wuld contat me if they felt a follow up was needed. Also, the vehicle had 'catastrophic' computer failure with power lost and warning lights within first 2 years --transmission lost power/engine still ran and forced into the breakdown lane and have vehicle towed. . Dealer did some type of reset. VIN # 5FNYF8H59PB027063
