After many, many, many attempts to install them on a 2009 Honda Pilot I had to give up. The top holes are misaligned - even after repeatedly raising and lowering the car with minimal adjustments to try to align the holes. There are similar reviews that also point to this issue with the 2009 Honda Pilot's top vents. I didn't want to drill holes or enlarge them, that's not my job. Poor manufacturing, poor quality assurance processes.
