While driving, the front driver's side tire and wheel detached from my vehicle, causing significant damage. My vehicle was last serviced at dealer on September 2024. During this service, significant maintenance and repair work was performed, including machining rotors, wheel alignment, and tire rotation. I am concerned that either a malfunction or an improper connection of the wheel has led to this incident. Since service, I have driven approximately 2,000 miles and have not had the car serviced by any other provider. My driving has been limited to general day-to-day use, with no long road trips or encounters with curbs or potholes. The evening prior to the incident, I noticed minor steering wheel shaking while driving over 60 mph and a slight grinding noise. I decided to make an appointment for service on the next day. Unfortunately, while en route to the service appointment, the entire driver side wheel and tire detached as I was making a right turn to enter the highway.

The contact owned a 2021 Lexus RX350. The contact stated that while his wife was stopped at a red light, the vehicle was rear-ended by another vehicle traveling around 65 MPH. During the collision, the driver's side seat reclining mechanism failed to hold the seat in an upright position, allowing the seat to fall backward, resulting in the driver sustaining injuries that the contact attributed to the failure. The air bags did deploy. No warning lights were illuminated. The vehicle was towed to a tow yard and deemed a total loss by the contact's insurance provider. A police report was filed and injuries were reported. The contact's wife was transported to an area hospital by EMT and treated for nondescript injuries to her left hand, left wrist, and both shoulders and bruising to her right hip. The manufacturer was notified of the failure, and a case was opened. The contact was later informed that the vehicle was inspected and that the driver's seat reclining mechanism did not show signs of failure. The failure mileage was 24,000.
