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.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2026 Toyota Grand Highlander Hybrid verdict →
