NHTSA Complaint #11443368 — 2017 TOYOTA HIGHLANDER

I purchased my Highlander new in 2017 and I have had consistent electrical issues. I the radio has consistently fluctuated between bass, treble, and off for no apparent reason. I have taken my vehicle to the dealer 4 times and still no change. I have replaced the battery 3 times although I only have 25,000 miles on 55,000mile tires, the tire treads are wearing quickly. I rarely go anywhere and when I do it is on smooth surfaced, well-maintained roads. All maintenance is completed at the dealership, including rotation and balancing. I really so annoyed and I see by the comments that I am not alone in these issues. I'm not even going to get into the plastic chrometek wheels. However, Toyota states there are no problems.
