2021 HONDA ODYSSEY Forward Collision Avoidance Adaptive Cruise Control Problems

All of my assist lights just came.on one after another saying there was a malfunction with the emmision light continues to go.on go.off even after I paid 580 to have the car serviced for the assist lights. Now the lift gate stopped working three weeks ago yesterday with all the rain that poured now the lift gate is open and will.not latch.

I was driving in light snowfall when several alerts notifying me that the radar sensor was not working. This is common in snow fall. Later I cleared off the radar unit cover (The Honda logo on the front of the car). The alerts remained. I took it to the dealer and they dubiously told me it was "damaged by snow". This is impossible. It was light snow. There was no collision or impact. This device should be durable. It has no moving parts. But Honda wants me to believe that it simply stopped working from driving in a light snow. They want $1300 to replace. How do I know the next one won't conk out after the first snowfall? These units should have a lifetime warranty with only exceptions for collisions or impact damage. If the unit is damaged by snowfall, it's clearly too fragile and should not be on...

The children message that the radar is obstructed, I did the clean where is the radar is but the issue still.

After a slight rain, the error of Radar Obstructed is being displayed. Can’t get this error removed or fixed. After searching more I found out that: 1. Honda has a defective design in the Advanced Driver Assistance Systems (ADAS) of all Honda Odysseys, models 2018-2023. 2. Namely, Honda has placed the RADAR behind the large HONDA emblem on the front grille. This causes the radar to give a "RADAR OBSTRUCTED" warning, which disables all Advanced Driver Assistance Systems in the car (Automatic Emergency Braking, Adaptive Cruise Control, Forward Collision Warning). 3. The "RADAR OBSTRUCTED" warning cannot be reset by restarting the vehicle or disconnecting the battery, requiring recalibration of the RADAR at the cost of $800 each time since it takes several hours to do (per Dealership). 4. The official Honda Odyssey Forum online has countless complaints on the same issue without resolution by Honda. 5. Honda has acted in...

I am writing to urgently bring to your attention a critical issue plaguing the driver assist systems in Honda Odyssey 2018+ vehicles. Despite meticulous maintenance and adherence to manufacturer guidelines, I have encountered a persistent and alarming problem that appears to affect numerous other vehicle owners, as evidenced by online forums and discussions. The issue initially arose during a rainstorm, where I received a warning message stating, "Some Driver Assist Systems Cannot Operate: Radar Obstructed." Despite the weather clearing and thorough cleaning of both the sensors and the windshield camera, the warning persisted. Subsequently, a series of related problems emerged, including: Illumination of the BRAKE SYSTEM LIGHT Malfunctioning adaptive cruise control Faulty collision mitigation system Inoperative road departure mitigation system These errors not only pose a significant safety risk to myself and others on the road but also indicate a systemic issue with the vehicle's safety systems. As my vehicle...

Once the cruise control is set, it consistently drops below the set speed and surges back up or over the set speed. Set on 62, it drops to 59 or 60, then surges back up to 62 or 63. This happens on perfectly flat roads with no traffic in front or beside the car. The dealership tried to tell me that the camera for the adaptive cruise might be seeing things in its peripheral vision area, but there is nothing there, the shoulder of the road is wide and free of obstacles. I've owned many other brands of vehicle, and never had this trouble with the cruise control on any of them. This is also a safety issue because sometimes it just randomly slows down or speeds up when there are cars behind you or beside you.

The VSA modulator has repeatedly failed. When it fails, all of the safety systems report errors - air bags, ABS brakes, high beams, traction control, blind spot detection, parking sensors, etc. Additionally, the power sliding passenger doors and tailgate will not open, even manually. I have taken it into Honda dealerships on 3 separate occasions. On 6/14/21 (vehicle mileage 7,453) they cleared the error codes and reset the system and reported it was fixed. On 2/26/2022 (vehicle mileage 21,077) it happened again and they reported the VSA modulator as defective and replaced it under warranty. On 7/29/2022 (vehicle mileage 26,916) it happened again. This time the dealership disconnected and reconnected the VSA modulator and it decided it was fixed. At the time of the issue I was driving the van at approximately 30 mph on flat streets through my town. I've expressed my concerns that this defect renders the vehicle...
