    The Electronic Park Brake (EPB) fails to release when the car is shifted into gear. The park brake dashboard light remains on, and the brake does not release. The problem is intermittent but has occurred multiple times in the first 2 months and 2,000 miles of owning the newly purchased vehicle. The vehicle was purchased in Nov 2025, and in Jan 2026 it was taken to the authorized Toyota service center at the Toyota dealership where it was purchased to have this issue repaired. But Toyota refused to replace any parts. Multiple photographs of the brake failure were provided to the Toyota service center, but they will not replace any parts or do any repairs related to the issue unless they can replicate the intermittent failure while the car is at the service center garage.

    I recently purchased a Toyota Grand Highlander just two days ago, and I’m experiencing a serious issue that is affecting my ability to drive the vehicle safely. At speeds between 25–40 mph, there is a significant cabin boom and echo inside the vehicle. This creates a pressure sensation in my ears, causing nausea, disorientation, and physical discomfort. I’ve only driven about 50 miles, and the symptoms are severe enough that I cannot continue driving the vehicle.
