rear tailgate window spontaneously shattered
Driver side rear sliding door will not open even when the automatic release button is disengaged. Some could be trapped in an emergency or I am worried that if it opens I will not be able to get it closed.
All of my ADAS systems were disabled due to a water leak. The repair required the dealership to hire a "leak doctor" and then replace a module in the rear tailgate. My vehicle showed an alert on the dash that each of the ADAS features were disabled, auto high beams were disabled, and I could not turn the vehicle off by pushing the start/stop button once, I had to use a procedure that forced the vehicle to shut down. My interior dash lights flickered, I'm not sure if the headlights worked. As the interior dried out, the flickering occurred less frequently. I was able to drive the vehicle to a Honda dealer for repairs.
The power liftgate opens, but then closes unexpectedly. It will open fully, dip down a couple inches, open back up fully and then close quickly. It does not stop closing when it meets moderate resistance, only stops when the button is pressed. I was unloading groceries into the back and it came down on me. Luckily, I was able to reach and press the button. Had it been my children I'm afraid it would have crushed them. This has now happened numerous times and through research I have found a Honda service bulletin about this known issue. I feel it should be a recall since it poses a safety hazard. As I said, it could really harm someone not able to move quickly or a child could lose a limb or be crushed. I shouldn't have to pay for a very expensive repair to maintain safety when Honda knows this is an issue caused by a defect in the spring assembly. Service bulletin 22-018. This happens nearly every time I open the liftgate now, less often when it's cold outside than when it is warm. Makes it hard/nearly impossible to use my trunk space.
The rear hatch will randomly close after it is opened. The hatch will not stop closing if someone is standing under it. Several times now it has closed while someone is getting something out of the back and you can not make it stop without quickly getting out of the way and pressing the button. Both, myself and my wife have been hit pretty hard on the head by the hatch closing on us. This is a HUGE safety concern as I have children that could easily be harmed by the sheer power of this hatch. I have had the issue inspected by an independent shop and was informed that it would need both new power struts at a cost of over $1,200! The van is only 5 years old with 75,000 miles! There are no warning lights, messages or problems prior to the failure.
The power tailgate continues giving issues. I made the first repair about 1.5 years after purchasing as a new vehicle purchase. Now a few years, after the first repair, I', seeing the same issue. The power tailgate stops working and makes all the warning lights on my dashboard light up and drains my battery. During the last repair, the tailgate power unit was replaced as water gets into the compartment and causes damage. Initially it affected the driving assistance, the power steering system and lights as they were all acting up, with the dashboard full of warning messages, when the tailgate initially stopped working.
Sliding door stopped operating as a result of "badly torn inner bushings" which required the door motor and control arm to be replaced. This occurred just from normal use of the vehicle. At certain points, the opposite door also began to exhibit the same symptoms as the other. Furthermore, this problem did not just happen overnight, these components should be made part of a normal inspection just like the cabin air filter. Why is that inspected but the bushings of a sliding door are not? Could it be so the manufacturer or service department is hoping for these components to break so that it can gain business and work?
The rear hatch door closed with me standing under it and I injured my arm trying to stop the door from closing on me. The door will not stop closing even with a person there. This is very dangerous! The mechanic said that we need to replace the rear struts- this car is only 3 years old!
Power Sliding Door Reverses Direction When Closing as if something was in the way. This happens intermittently for both doors. We have to force the door close by passing the safety system. I know for the 2018 and 2019 models Honda. https://static.nhtsa.gov/odi/tsbs/2020/MC-10171536-0001.pdf Dealership is not able to see the issue with the car. I know this has been an issue with Honda Vans.

The failure mileage was approximately 55,000.
While driving on a surface street at approximately 35 MPH on a 100+ degree afternoon, the glass moonroof suddenly exploded. I did not observe any object striking the car or the roof. The shade was closed, so glass did not enter the cabin. However, driving the car above 30mph became impossible due to air impinging on the shade and making it more likely that the shade would open and glass would fall onto me.
