BACK OVER PREVENTION: WARNINGS
This is regarding recalls for my 2024 Toyota Grand Highlander Hybrid Platinum Max. The vehicle has been in the possession of Koons Tysons Toyota since December 23, 2025 (80 days as of 3/11/26), for repair of Safety Recall #25TA13 and #25TB13 NHTSA 25V744) involving the Panoramic View Monitor System/Parking Assist ECU. The dealership has explicitly informed me that the vehicle is unsafe to operate and have therefore kept it. Toyota and its authorized dealer have made three (3) repair attempts to correct this safety defect. Two separate replacement components were ordered and installed without resolving the issue. A third required component is currently on backorder with no definitive ETA or repair completion date, as the date keeps getting pushed. We are not being updated and are not receiving information from the dealership and Corporate about the details about the problem and nature of the delay. Toyota has obligations under federal recall law administered by the National Highway Traffic Safety Administration (NHTSA) to remedy safety defects within a reasonable time and at no charge to the consumer. An indefinite inability to complete a safety recall repair due to parts unavailability raises serious concerns under those obligations. Furthermore, a previous recall #25TA08 (NHTSA 25V595) which was supposedly completed on October 14, 2025 by the same dealership is showing as INCOMPLETE in the vehicle record with NHTSA.

LANE DEPARTURE: BLIND SPOT DETECTION
The contact owns a 2024 Toyota Grand Highlander. The contact stated that there was a small crack on the windshield on the driver's side at the top where the windshield meets the frame. The contact stated that the crack had started to expand. The contact recently noticed another crack in the center of the windshield, starting at the bottom. The contact stated that both cracks were approximately 5 inches long and expanding. The contact had not struck a rock or road debris for the windshield to crack. The contact had taken the vehicle to a dealer to be diagnosed and was advised by the dealer that the cracks were the result of small stones being kicked up by other vehicles. The vehicle was not repaired. Additionally, the contact had been experiencing failures of the infotainment screen going black, and the side-view mirror Blind Spot warning lights not functioning as designed. The vehicle had been taken to the same dealer several times, and the dealer resolved the issue. The contact stated that the infotainment screen failure had reoccurred. The manufacturer was not informed of the failure. The failure mileage was approximately 40,000.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
While slowing to a stop on a slight incline (an interstate off-ramp), when almost stopped, the car started bucking as if the brake pedal was being slammed on, then released, slammed on again, then released, and repeated for maybe 2 seconds. I quickly hit the "P" (Park) button to take it out of gear and it stopped. No warning lights or anything came on and it drove perfectly fine afterwards. It felt just like the emergency braking and the car thinks you're going to hit something. It was very strong and jarring. Happened a 2nd time on April 4 in the same circumstances - driving downhill on a highway off-ramp and stopping at red light at the end of the ramp.

Dash board appeared safety issue warning and ask to contact dealer. I have been to dealer 3 times since bought the vehicle last year. The first time it appeared was after I bought the vehicle for a week. I brought the vehicle back to the dealer and ask for a refund or exchange another one, and was denied. I happened 2 more times and I brought in again. They said that they adjusted the sensors for a less sensitive level. I contacted toyota to exchange or return the vehicle last year. They got my information down and never replied to me until now.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The car is not involved in an accident, but TYOTA and the dealership cannot provide an ETA for when the issue will be fixed. It would be great if the vehicle could be returned or traded for another vehicle if there is no fix available. However, without losing my money as the dealership wants to take it less than 10K even it has been less than 3K miles.
NHTSA complaint #11613246 — an unverified report by a vehicle owner.
LANE DEPARTURE: ASSIST
Toyota has issued a STOP SALE and RECALL on the airbags in this vehicle. There is no anticipated time for resolution but rumors indicate it might be October. During this time the airbags would not deploy if you are driving with the front windows down as it affects both driver and passenger side. We bought this car with the expectation of quality and my confidence is not high given Toyota has also issued recalls on engines in the Tundra. I have contacted Toyota Customer Care, a case was created and I was directed to the dealership for any additional action or updates. The dealership has indicated that the warranty administration has not authorized loaners as there would be no reason for me to drive with my windows down. While that might be true this time of year due to extreme heat I may take the car with me to cooler climates and have the windows down. The Lane Keep Assist seems to be aggressive at times trying to get me to "stay" in my lane when I have been driving and maintaining a center position in the lane but feel it pull the steering wheel when it seems unnecessary. I am unclear if this is a defect in the software or cameras or if it could be the result of a sensor with some debris or obstruction over it (i.e. dirty windshield or bug splatter)

BACK OVER PREVENTION
The contact owns a 2024 Toyota Grand Highlander. The contact stated that while his wife was in reverse at 10 MPH, she collided with another vehicle. Though equipped, the back-over prevention system failed to activate, which could have potentially prevented and/or lessened the collision. The air bags did not deploy. No warning lights were illuminated. A police report was not filed, and no injuries were reported. The vehicle was taken to an independent mechanic, who was unable to duplicate the failure and informed the contact that the incident recorder does not log data for incidents under 25 MPH. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 500.

The hood vibrates at 50mph on the back 1/4 th closest to the windshield. It’s very distracting while driving. I also had an incident where adaptive cruise control in light rain did not appropriately anticipate traffic up head and I had to slam the brakes myself.

The center console display stopped working the next day I picked up my car. This display also displays the feed from the rear-view camera, which is flaky because of this issue. The center console display enters a reboot cycle; it reboots every minute, distracting me while driving. I picked up this new vehicle on Dec 15, 2023. This issue started occurring on Dec 16, 2023.
