“My van been giving me some weird issues lately. When I’m going downhill, my brakes don’t seem to work well! I have to push it all the way down, like a spongy.

Dealership wipers”
NHTSA complaint #11658450, filed 2025-05“The driver’s side door mirror shakes when going down the road. The image in the mirror becomes shaky. The passenger side is fine, this is only on the driver side. I have brought this into the dealer, but they said it is normal. In 30+ years of driving cars, I have never had a car mirror do this.”
NHTSA complaint #11706330, filed 2025-12“While slowing down from highway speed 55mph to about 30 mph preparing to turn right, I heard a huge explosion (sunroof). Thinking it was overhead, I slowly pulled back the sunscreen which blocks out the sun from the roof, realized it was full of broken glass and immediately closed it. This was a terrifying event and could of easily caused serious injury or worse. My dog was riding in a secured dog crate in the rear of the van. The van was taken to the dealership for investigation and repair. …”

NHTSA complaint #11435445, filed 2021-10, 12,000 miles“With the rear seat entertainment system in use, the rear visibility is completely blocked in conjunction with the standard rear view mirror. This is a major design defect and is avoidable with available options that should be standard. Without being able to utilize all possible ways to view around the vehicle, Toyota has put its owners, occupants, and fellow drivers at unnecessary risk. An easy remedy is Toyota retrofitting and including going forward their digital rear view mirror.”
