2017 Lexus Rx

When checking the emergency SOS function in my car I found that it did not work. I called Lexus support and was told that the following safety systems would no longer be operative: Lexus Enform Safety Connect including Automatic Collision Notification; Enhanced Roadside Assistance; Emergency Assistance Button and Stolen Vehicle Locator; Lexus Enform Remote including Remote Engine Start/Stop, Door Lock/Unlock, Vehicle Finder, Guest Driver Monitor, Vehicle Status and Alerts, Key Fob Remote Start, and Integration with Alexa® and The Google Assistant; Lexus Enform Destination Assist including 24-hour live response center agent; Lexus Enform Service Connect including Vehicle Health Report, Vehicle Alerts, and Maintenance Alerts; These include safety systems that I rely on, especially when driving on interstate highways, and were included when I purchased my car. I had no warning that the services would cease to function in October of this year. Lexus states that these systems will no longer function because telecommunications providers will no longer support 3G service. This is certainly a safety issue for me and for other drivers and I believe that Lexus should be required to modify the hardware/software in these vehicles to function in a 4G/5G environment. Lexus representatives state that Lexus has no plans to correct these safety issues. I am requesting that NHTSA review this matter as a highway safety issue.

Sunroof Glass Failure Report: I was traveling on the interstate at the speed limit and there was a loud bang, which after I pulled over, discovered that the sunroof had "exploded". There was no sign of anything hitting it and the weather was typical for the Texas Gulf Coast in a July morning. Luckily, the underneath cover for the sunroof was closed, because several pounds of glass fragments were released in the sunroof failure and would have been all over the passenger compartment of the Lexus. This is a major safety issue, especially if a child is fastened in a car seat with this problem directly overhead. This issue has been reported by numerous other Lexus owners and seems to occur often enough that it should be a concern for the manufacturer, but I am not aware that they have taken any action on this. A photo of the failed sunroof is included.

I hear a loud clicking sound that is coming from the vacuum pump that sends vacuum to the brake booster, I am concerned that it could eventually cause braking issues.in the future if not corrected ,i have read multiple forums and it seems to be a common problem with this particular vehicle and ones similar to it, I would like to have this issue resolved before a traggedy occurs.
