The sunroof on my 2021 Toyota Highlander spontaneously exploded. I was merging onto a highway but just started to accelerate normally - was going approximately 20-30 mph. The entrance ramp was a merge lane, and there was a semi truck with no load, so intentionally accelerated slowly to allow the truck driver easy access to the highway. The temperature outside was approximately 80 degrees, clear skies, no construction around me. No object from the truck in front flew backwards to hit my Highlander. It sounded like a gunshot, but felt no impact to the Highlander. I slightly opened the sunroof liner, because the loud noise seem to come from directly overhead. I saw that the sunroof was shattered, so quickly closed the sunroof liner to prevent any glass from falling down. I exited the first exit and drove to the dealership. Ironically, I already had an appointment for routine maintenance. …
THE ENGINE COVER ASSEMBLY DETACHED FROM THE BOTTOM OF MY CAR WHILE DRIVING. SIMILAR TO THE EXISTING RECALL FOR THE FRONT LOWER BUMPER COVER ASSEMBLY. While pulling out of a parking lot, I noticed that there was a scraping noise under my car. Prior to parking at Jones Beach State Park, I was traveling on Ocean Parkway at a high rate of speed (50-60MPH) and it was a very windy day. I did not hit any obstructions or scrape the bottom of my car on anything. There was nowhere for me to pull over and as I sped up, the noise went away. When I got off the highway, the noise returned. When I got home, I looked under my car and there was a plastic piece dragging just in front of my front tires. I remembered I had received a notice about a Toyota recall related to the lower front bumper cover assembly and looked that up - it felt very similar to what I had experienced. …
