I have experienced multiple instances where the vehicle's transmission abruptly downshifts into lower gears, significantly reducing speed and creating a hazardous situation. This unexpected behavior has occurred on the Interstate, both while merging onto the highway and during regular driving conditions. On two separate occasions, my daughter was driving the vehicle when the transmission malfunctioned while driving on the Interstate. She was terrified as she believed she was losing traction and was unable to accelerate properly, putting her life and the lives of others at risk. I have personally experienced this issue as well when attempting to merge onto the Interstate under clear and dry road conditions. The vehicle would not exceed 35 mph, creating a dangerous situation. To rectify the issue, I had to pull over to the side of the road, place the car in park, and then put it back in drive to regain normal acceleration. I have used a code reader to check for any diagnostic trouble codes, but none were present. However, a blinking traction control light illuminated during these incidents, indicating a potential issue. I am deeply concerned about the safety implications of this problem.

The contact owns a 2021 Honda Passport. The contact stated that on numerous occasions while driving at undisclosed speeds and making left or right turns, the vehicle independently decelerated. The contact stated that the engine revved, and the RPMs increased; however, the vehicle failed to respond with the accelerator pedal depressed. The contact turned off and restarted the vehicle for the vehicle to return to normal operation. No warning light was illuminated. The vehicle was taken to the dealer however, the failure could not be duplicated. The contact stated that the failure recurred. The vehicle was not repaired. The manufacturer was notified of the failure and a case was opened; however, the contact was recently informed that the case was closed. The failure mileage was approximately 30,000.

This car accelerates when down shifting in mid to higher gears. We were in the snow on a steep decline and when I downshifted into 4th gear the car immediately accelerates ( Not Coasted ) but accelerated increasing my speed before finally downshifting. It is also having similar issues with the 7th, 6th, and 5th gears. We lost traction immediately after shifting when the car accelerates and I have no drought that we would have crashed if we were approaching or in a turn at the time. 12/28/22 I spoke with the dealer today and he was aware of other complaints. I made an appointment to have them check it out tomorrow 12/29/22. I have repeated this issue multiple times and plan to show them. This also happens every time you downshift into 4th gear etc on dry or wet pavement, even on flat surfaces.
We were driving at 55mph and every warning light came on. It quickly decelerated to 20mph then wouldn't shift from first gear. We were in an area where there was no places to pull over. We pulled over and the car wouldn't shift from park. We were told to let it sit 15min then try again. After 20 min the car worked normally. The …

We were driving at 55mph and every warning light came on. It quickly decelerated to 20mph then wouldn't shift from first gear. We were in an area where there was no places to pull over. We pulled over and the car wouldn't shift from park. We were told to let it sit 15min then try again. After 20 min the car worked normally. The computer system deletes all the errors once it sits. The dealership says there is nothing wrong. This is the 2nd time it's done it. We were told to check the battery. It's new and we do not trust this vehicle. If it does it on the freeway it would be catastrophic. Honda needs to fix this problem. The crash avoidance also says to brake at every car in the opposite lane. I purchased a code reader to try and save all the codes when the car acts up.

My 2021 Honda Passport first shifted itself into neutral and displayed a message on the instrument panel saying “Stop Driving When Safe. Transmission Problem. See Manual” in February 2022. My dealer inspected the vehicle and said no problem codes were stored and returned the vehicle to me. In May 2022, my vehicle displayed the same message and shifted itself into neutral while backing out of a parking space. This resulted in my vehicle rolling forward into the curb. Luckily my vehicle was parked by a curb and not in front of another vehicle where a collision could occur or pin a pedestrian between the two vehicles. My dealer inspected the vehicle again and stated no codes were stored and returned the vehicle to me. Honda has been contacted twice regarding the issue and on the fourth repair attempt, a field engineer inspected the vehicle and could not find any codes stored. The engineer also recommended the vehicle be kept in park while it is not moving.

My 2021 Honda Passport with under 12K miles has gone into Neutral on its own twice in the past year ( May and October of 2021) It has also slipped into low gear on its own (D1 of an automatic transmission from D3 or D4 in Oct 2021 and March 18 2021. The last incident forced me onto the shoulder to avoid serious injury as I was gaining speed to merge from an entry ramp to a 50 mph, 3 lane Rd. I brought it back to the Honda dealer after the March 18 incident and they told me they couldn't find anything wrong with it. I don't trust this transmission and will be forced to sell it back to Honda but am leery of it happening to someone else who may not be able to avoid an accident like I did. I also reported these incidents to Honda on 03/24/22 (case# 12912165)

Had the optional transmission cooler installed at the Honda dealership to help increase vehicle towing capacity. After install, when the vehicle shifts from 7-8 gear at light throttle application (approx. 45mph) the transmission makes a grinding noise. Took vehicle back to dealership and they inspected. They contacted Honda tech support and they stated it is a known design defect. They will not address it in anyway even though there are many possibilities to address this. Noise is energy and energy has to dissipate. I am concerned the grinding noise will start to wear something out and cause a failure later in the life of the transmission or the cooler.

See Manual" When this happen the car automatically shifts into Neutral and will not shift back into any gear other than Park unless I completely restart the car. Many other people have also had this problem, can be seen here https://www.passportforums.com/threads/major-transmission-failure.2984/ I believe there is a major issue with the transmission on some Honda Passports that is potentially fatal. I took the car in once to get it looked at and they could not find anything wrong with the car, it has happened since I took the car in to repair.

Car shifted into neutral on its own while accelerating up a freeway on ramp with a transmission error warning light on dash and could not get the vehicle to go back into gear until ignition was cycled a couple times. Obvious safety risk as any vehicle movement was impossible, and was not able to completely coast out of the traffic lane. There was no known symptom prior to this event and the vehicle is currently at the dealership for repair/warranty evaluation though they state "it is not showing any error codes on the diagnostics plug in", they did state that on test drive it "behaved perfectly until coming back to the dealership and acted up again....again showing a dash warning but no diagnostic code."

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy.

The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign.
