2022 Lexus Es

I purchased my car approximately four months ago, and the lights on my dash began blinking there was a warning to clean parking sensors. I went to the dealership to see what this meant. They stated I have a missing sensor and immediately stated it was not covered under warranty. I haven’t had any wrecks or bumps on my car. I asked if it could be a default with the glue that holds the sensor in place. The manager said that’s not possible someone had to push the sensor out. He continued to state they have had several cars come in with the same issue and people are pushing them out. This has caused warning lights to come on in the vehicle due to this default the dealership stated it was a wear and tear and would not be covered under warranty. It also causes the car to beep as if you are going to hit something every time you start he car. Even if you turn off the system, it still beeps and blinks as if your car will shut down. the parking sensors are defective in the sense that they are not secure and being installed which is causing repair approximately $900-$1000. I stated it has been extremely hotter than normal with a consistent temperature oaf 102+ in Arkansas. He was not open to the fact and basically said pay or leave. He refused to give me an estimate on the cost unless I paid the $100 diagnostic fee. I feel that if several people have been in for the same reason it’s should definitely mean there is something defective with the front bumper sensors. I have not even drove 10000 miles and now there is a repair not to my fault that I am having to pay as if the car is t expensive enough. I believe there needs to be some sort of recall on. This section with how they are installed. He said they glue them on the back side and glue does melt..please look into this.
