Example complaints

“The vehicle has had rocks get in the suspension 4 times so far which creates loud clunking noises and can cause a noticeable feel in the steering. The most recent time, after the rock entered the front end, the brakes were soft and required excessive pedal force followed by a clunk before the brakes abruptly applied. I like on a paved road with a rock driveway and it seems like the shielding for the front end is inadequate. I have friends with a 2022 sienna that live on a gravel road that have experienced similar issues.”
NHTSA complaint #11523611, filed 2023-05“While driving approximately 70 MPH the vehicle tends to float or wanted to change lanes on me. The vehicle would jerk to the left or to the right requiring corrective action on my part. At first I attributed the problem to the windy conditions, but later decided the wind was not the cause. It appears that when driving less than 40 MPH, there is no problem. This problem continued for my entire trip (about 1400 miles). This is a vehicle that was modified by VMI into a handicapped accessible van. I don't know if regular Toyotas do this or not.”
