My 2007 LS460L has the electrical system shut off for like a second while driving

Asked by Jun 10, 2017 at 05:43 PM about the Lexus LS 400

Question type: Maintenance & Repair

My 2007 LS460L has the electrical system shut off for like a second while
driving. Happened on a long trip after being on for about 200 miles. I was
driving at about 70 MPH. It was just a second, but I could feel the power
steering tighten, and the radio reset. It did it about 10 times over 20
minutes. I pulled into a rest stop, turned it off and let it sit for 10 minutes,
restarted and it ran fine for another 120 miles. This week, I made about 5
trips about 15-20 miles each day, with no problem. Yesterday, it did it again
after the car was running about 20 minutes at 45 MPH or less
