2020 Lexus Rx

While into a road trip from Florida to Tennessee on I-75 the sunroof spontaneously exploded. The interior sunshade was closed. Otherwise the glass shards would have entered the interior. The glass most likely would have caused cut injuries to the driver (my wife) and I. Also, it may well have caused her to lose control of the vehicle resulting in a very serious accident while driving at 75 mph. My insurance company classified it as vehicle mechanical failure and not covered by my insurance. They indicated this has happen to other vehicles including Lexus. The replacement cost for glass and labor was $1,087.75

Just after topping a hill on an Interstate Highway, both lanes of traffic ahead of us came to a sudden and complete stop. I was in left lane and reacted quickly and applied full braking power and managed to stop a foot or 2 from the rear of the stopped car ahead of us. A few seconds later we were hit from the rear by two cars, one, a Black late model Camry, which almost stopped and a 2nd, a large, new German-maker grey SUV, which never applied brakes, destroyed the black Camry behind us and then destroyed our car, when it hit the left rear and after impact continued pushing the front of the car into the steel cables separating our lane of travel from the oncoming traffic in the other lane of the Interstate, until the steel cables stopped us. Neither the electronic collision alert system, the air bags or the emergency braking system activated. The electronic system in our new Lexus then came on and told us that the collision alert/airbag activation system was defective and to contact our dealer for inspection and repair. However, our car was totalled destroyed and taking it to a dealer for "inspection" was neither possible nor practical, but my wife and I walked away without any known injuries. Lexus was advised of the defect, the extent of damage, and told where car was and invited to inspect it. Not sure if Lexus ever inspected it.

Was driving into the garage (coasting) very slowly and as I was preparing to step on brake the car revved forward unsuspectedly - I have a video on my ring door bell and you can hear the engine then the squealing of the automatic braking system. I destroyed the adult 3 wheel bicycle that was stored along the wall but that helped the vehicle from crashing through the bricks - I remember shouting “what the hell is happening”. After much research as I knew I did not depress the accelerator in error - I found that this has been a common occurrence with Toyota and Lexus products. I am a very careful driver and I have replayed the incident in my head over and over. I presently dont have the insurance and repair information Readily available
