While driving my new Grand Highlander, I have experienced a serious and recurring safety issue. Even with lane assist turned off, the vehicle automatically steers to the right when I exit a regular highway — apparently misinterpreting the widening road as a lane shift. When this happens, the steering overrides my input and I am forced to pull the wheel hard to regain control and stay in my lane. This loss of steering control is dangerous and frightening, and I am formally reporting it as a significant safety concern that requires immediate attention.

NHTSA complaint #11731349 — an unverified report by a vehicle owner.
When I went to turn the car on last Tuesday (3/24.2026), the entire digital dashboard was black. I tried restarting the car a few times with no resolution. Thankfully, the infotainment screen and heads up display (HUD) were on and working fine. If it was not for the HUD, I would of had no idea what my speed was driving home. However, I was unable to see my gas level or other safety features which is concerning. Once I got the car home about 15 minutes later, we turned the car off and back on and everything was fine. So far, everything has been working normally ever since. I did take a picture of the black screen as you can see for proof. Please reach out if you need more information.

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.

The contact owns a 2025 Toyota Grand Highlander. The contact received notification of NHTSA Campaign Number: 25V744000 (Back Over Prevention); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was contacted and diagnosed the vehicle and determined that the camera had failed, and that the contact would be notified when the remedy was available. The contact stated that after leaving the vehicle with the dealer, the back over camera started to fail. The back over prevention camera no longer switched the screen for the camera while in reverse, but remained on the home screen or radio instead. The contact had not heard from the dealer regarding the parts availability for the repair. The manufacturer was not made aware of the failure. The failure mileage was approximately 29,000.
NHTSA complaint #11713620 — an unverified report by a vehicle owner.
The Electronic Park Brake (EPB) fails to release when the car is shifted into gear. The park brake dashboard light remains on, and the brake does not release. The problem is intermittent but has occurred multiple times in the first 2 months and 2,000 miles of owning the newly purchased vehicle. The vehicle was purchased in Nov 2025, and in Jan 2026 it was taken to the authorized Toyota service center at the Toyota dealership where it was purchased to have this issue repaired. But Toyota refused to replace any parts. Multiple photographs of the brake failure were provided to the Toyota service center, but they will not replace any parts or do any repairs related to the issue unless they can replicate the intermittent failure while the car is at the service center garage.

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.
