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.
Driving approximately 72 mph when vehicle died causing a potentially very hazardous situation - check engine light came on, master warning light came on, see dealer for repair message displayed. Was able to limp to side of road and had vehicle towed to dealership. After 2 days of diagnostic testing the engine control module (ecm) was replaced under warranty (less than 12,000 miles on vehicle). The vehicle is running, however, now notice a decrease in gas mileage and difference in transmission shifting since replacement.
The hands free calling feature has a serious echo when calling to the driver while on the road making it useless to use. It is California law states that calls made while driving must be hands free. This problem has existed since the car was purchased new. It forces the driver to handle incoming calls using a cell phone without the hands free while driving. My wife and I want Toyota to repair our car free of charge . My wife and I researched this problem on line and apparently this is a ongoing issue with Toyota’s 2019 and older. We want it fixed or we shall move forward with the lemon lemon law.
