High frequency vibration of the driver side external mirror at speeds above 45 miles per hr. As a result it impossible to make out vehicles and vehicle details beyond 15 meter behind. It's hard to focus the eyes to mirror. Could be happening to passenger side to but undiscernible from driverside. Vehicle issue found less than 5 days from the date of delivery(1st Sep 2022). Toyota doesn't have a solution is what the dealer is saying trying to get replacement mirror. Issue had been confirmed Toyota refusing to provide replacement or acknowledgement of the problem. Problem with Toyota safety sense drcc, lda, lta, etc. There is a body roll, at high speed and cornering vehicle feel unstable. During drcc if the speed is set say at 70 miles, one has ability to accelerate more by pressing the accelerator. Say the speed is increased to 80 miles per hr. The car doesn't sometime start slowing down after taking foot off the pedal. Sometime the speed continues to increase where the car should start slowing down when pressing of the pedal stops. Had to force brake due to safety concerns and possibility of a accident with the vehicle at the front. Tested few times same behavior. The lane keep is finicky and many times just doesn't provide the visual confirmation at the gauge and misbehaves in cornering in a major way. Keep assist looses control and strat drifting to the left and the applied force tends to pull or force to the left the car left. Pull more to the left during cornering and the assist forces to the left on its own instead of staying in the middle of the lane. High speed cornering feels unstable and with drcc acceleration and speed doesn't account for vehicle stability. Had to brake multiple times to make sure the vehicle stability is not compromised. There seems to some level of system issue that is not getting addressed though this is a tested platform.
2021 Toyota Venza steering assist feature creates a safety hazard. The steering assist works with the cruise control and lane departure. When on, it appears that the steering assist picks up its position or centers the vehicle in the lane from the nearest white line on the right side. It positions the vehicle approximately 12 to 18 inches from the right line position thus positioning the vehicle slightly right of the center of the lane. One is forced to fight the pull of the wheel to maintain a center lane position. This steering assist function creates the following problems: 1. Off-center to the right can make it too close for vehicles traveling to the vehicles right. Also, it does not adjust for vehicles traveling too close or possibly swerve on your right side. It will maintain its position regardless of events alongside of you. It receives its bearings from only the white line. This condition is more severe when traveling in a left lane on a multiple lane road with a dotted line. 2. Because the steering assist picks up its orientation from a right-side line; when the line is out of position or not available, the car will automatically move right until it finds something to coordinate the cars position. Without something fixed like a line or curb it will take the car off of the road. When approaching an off-ramp, the right solid road barrier line, usually veers right off the highway and will follow the direction of the off-ramp. Under this condition I have discovered that the steering assist feature will actually take me off of the highway onto the off-ramp and alongside the right-most solid line wherever it goes. I feel that NHTSA still should examine any issue on a car that could make its operation unsafe. Furthermore, it appears that NHTSA has not performed any crash-worthiness testing including weight and roll-over. Why has safety testing and crash worthiness not been performed on this vehicle? lastly; why doesn’t it have a standard NHTSA door label?.
