Blind Spot Detection problems of the 2019 Honda Passport

Even after recall repairs the vehicle continues to randomly display error messages with vehicle systems while driving. It has been cleared several times and battery changed but continues to return. This model has serious issues with the electrical components.

Warning system failure… all lights lit and systems did not work. Car was drivable but with no safety mitigation systems. Happened suddenly while driving on hwy. Displayed the following warnings: transmission system problem blind spot info system problem power steering system problem emissions system problem vehicle stability assist problem hill start assist problem traffic stability assist problem road departure mitigation system problem rear tailgate did latch not working the d for drive was blinking these safety systems put my driving at risk as I rely on them for safe driving, lane change . . Etc brought to dealer for second time and they insist I leave the vehicle on so they can check the error codes. Even had ready made sign “ do not turn vehicle off” for dashboard. Seems like significant problem and I’m not the only one. Evidenced by chatter on Honda web forums. My question is, why do all system failure lights activate? why can’t they determine the failure after car is turned off. Isn’t that the purpose of fail codes? why do all safety functions fail when one issue arises. Evidence points to a software bug that effects all these functions (yes including the rear latch) dealer recommends replace the abs module but is not sure. Last time they replaced the speed sensor. Seems they are unsure. Needs software fix !.

The transmission system problem light appeared on the dash, and then the blind spot info system problem light appeared as well. The car refused to shift and caused us to pull off the road at night, put the car in park, and turn the car off on a busy road. It is scheduled to be looked at by friendly Honda in springfield IL on July 28th 2023 no the vehicle has not be inspected by anyone yet no there were no warning alarms at all prior to the incident.

Forward collision warning alert (brake) warning triggers frequently when opposing traffic is present. Sometimes the brakes apply that has led to several near miss collisions from being rear ended. The blind spot warning false triggers during wet conditions. Both of these items are distracting and first is dangerous. The two different dealers I have contacted are aware of these issues and have stated that Honda has no solution. One of the dealers said they could check/adjust the radar for $270 but may not fix the problem.
