What owners report
Vehicle began exhibiting multiple electrical safety issues around April 2025. EMF (electromagnetic field) levels were measured and found to be excessively high, causing physical discomfort and triggering health concerns for my disabled son and me.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The high-pressure fuel pump and related fuel system sensor failed, resulting in a sudden loss of engine power.
My vehicle has slowed while driving four times within the last 12 months. I have taken it to the Hendrick Lexus dealership in Charlotte as well as the Scott Clark Toyota dealership in Charlotte.
