2016 Lexus Rx

I was driving and pressed the button to close the sunshade on the panoramic sunroof when I heard this like a grinding noise. The cloth sunshade stopped moving. Then I heard a pop noise, and the sunshade came down, and it hit me more on the back of the neck. Then I heard something fall on the floor behind me in the back seat area. I couldn't pull over right away, stopped at a store, and there was a black, plastic and metal piece that was on the floor in back. The sunshade itself was partly hanging off the ceiling where it came from. It didn't hurt but of course it startled me. This happened on Friday going to work 7/18/2025. I haven't used the sunroof for a while because it has been too hot but Friday I wanted some natural air, and opened it up. Researching I see that it is supposed to be all one piece, and everything which includes the entire panoramic sunroof to be replaced which is close to $3,000. I found online that a lot of people have the same problem for years 16-22 on the RX. I found out where the dealers are telling people excessive heat melts the glue holding these adapters in place, and it eventually give way and break. Most people including me park outside, I don't have a garage, and it's summer, this is defective, and it should be covered my Lexus. Since it just happened yesterday, the vehicle wasn't inspected by nobody, there were no warning signs that this was happening either. The safety issue is when it hit me on the back of the neck while I was driving. Thank you for your time.

The vehicle sustained water damage due to Hurricane Ida in September 2021 and was repaired at the dealership. In February 2023, the battery needed replacing for a third time since then and I was told that the front and rear carpeting was soaking wet, again, and it was due to the moonroof rails being clogged. The vehicle is currently at the dealership being assessed and repairs should be borne by the dealer/manufacturer; NOT THE CONSUMER. If this is specific to my vehicle only, then I have a lemon. If it has happened to others, then it should be recalled.

On April 29 while travelling on I185 toward Columbus, GA I heard a loud noise followed by the sound of crumbled glass. When I could find a safe place to pull over, I looked and discovered that my moonroof had shattered. Had the curtain under the moonroof had not been drawn, I would have been hit with the shattered glass, probably resulting in my loss of control over the vehicle at interstate speed, resulting in a serious accident or death. I returned immediately to my dealership, Hennessy Lexus in Duluth, Georgia. They contacted the Lexus regional manager, who denied Lexus' responsibility for the failure. I did, (and needed to) have the moonroof repaired by the dealership. I also contacted Lexus Corporate office by phone, and sent them by email a copy of photos of the broken moonroof and the invoice for the repair. They passed my inquiry down to the regional manager (again) who again denied Lexus responsibility for the failure. The failure occurred in fair weather on a highway with very little traffic, trees or overpasses, and there was no reason to believe that any outside forces caused the failure. I feel that this potentially dangerous failure is a result of poor manufacture or design.
