2021 Toyota 4runner Transmission Problems

Your 2021 4Runner shut off completely while driving on the highway at 35 mph, then restarted after about 15 seconds—and this happened three times in one trip. You couldn't accelerate or steer while it was shut off. A few days later, warning lights and check engine lights started appearing repeatedly, and when they do, your transmission loses 2nd gear and lurches forward, making the vehicle very difficult to control. You've taken it to the Toyota dealer over six times, but they've only reset the computer and haven't found or fixed the underlying problem.
