Anyone else getting water pooling in the spare tyre well in their 2026 RAV4?
I've had my 2026 XSE PHEV since June and today was the first time I've looked in the spare tyre well. I noticed quite a bit of water pooling in there. The photos don't really convey the amount of water but it was about 2-3cm deep (about an inch). It took three towels to soak it all up.
My car gets parked outside and it is winter where I live so there has been some rain but not huge amounts. I've washed my car a few times and I use a hose not a pressure washer and the boot is always locked when I do. I don't think either of those things should cause this amount of water pooling.
My only thought is I had a towbar hitch installed back in June. It was by an installer the Toyota dealer recommended and they use themselves. Could something they have done caused this? I'm making an appointment to take it into the dealer in the morning but just wondering in the meantime whether anyone else has experienced this and what was the cause? Thanks.
