What's causing a steady, high pitched sound that appears to be coming from back
What is your question?
I have a 2014 Lexus GX460 with 64,000 miles. I hear a low volume, high pitch sound that appears to be coming from the backseat area of the car. It's constant, doesn't ever get louder or softer. And when I shut off the car, the sound continues for about another 5 seconds or so. Any thoughts as to what can be causing this?
What makes this problem better or worse?
it's always the same. I just purchased the car and the temps have been consistently hot (Arizona)
How long has your 2014 Lexus GX460 had this problem?
I noticed it after purchasing the car, about six weeks ago.
RepairPal Certified shops can diagnose and repair your 2014 Lexus GX460. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
The only noises I can think of would be fuel pump operation related (doubtful) and audio system noise. Have a trained technician near you listen for this noise together with you to weigh in first hand.
