Picture is of the mat after cutting a notch out for the vent.

I have a 2026 FWD non-Prime Prius and have been running the WeatherTech PN 4418102IM rear liner for a few months now. Picture is of the rear mat after being cut to clear the vent. Posting this in case anyone else is running the same mat, especially with the weather warming up.

I was cleaning my car yesterday and noticed a vent on the rear passenger side half blocked by the mat. A Prius Chat thread mentions that this vent could be the air outlet for the battery. I have emailed WeatherTech about the fitment issue to which they replied that they will let their product development team know.

*see all pics* Roofers replaced small piece of siding but they didn’t put any of the siding back under the corner post. 1st pic shows the step flashing and water proofing that they used underneath but im still worried water will get behind siding and cause water damage. It looks like the barrier doesn’t go more than an inch past the corner. Had them come back and they said it shouldn’t be an issue but should I be concerned?
