The vehicle hesitates and does not accelerate immediately from a complete stop. This occurs more frequently when the car is on a slight incline. The delay in acceleration creates a safety concern, especially when attempting to merge into traffic or pull out onto a roadway. I have reported this issue to the dealership multiple times, but they have not taken action because they have been unable to reproduce the problem.

I was driving toward the perimeter of my neighborhood, approaching an arterial cross street. When I braked the pedal went straight to the floor. The breaks didn’t work despite pumping them multiple times. I also heard the engine revving. To avoid the intersection and busy street I steered into a yard, hit a retaining wall and a tree, rolled and hit a metal city street sign. All airbags deployed. I was taken to the hospital by ambulance. The car was totaled and is on a temporary hold at a salvage yard.

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.

Description of Issue: I have experienced repeated incidents where the accelerator pedal becomes unresponsive (“dead pedal”) after coming to a stop. When pressing the pedal to accelerate, the vehicle does not respond at all for several seconds. Then, without warning, it suddenly surges forward with excessive acceleration once the power engages. This problem happens intermittently throughout a drive each day, often enough to be concerning. It occurs after being stopped at an intersection or in traffic. No warning lights or error messages appear before or during the issue. The delay followed by a sudden surge is dangerous, as I expect the car to move when I press the pedal, but it hesitates instead. When the vehicle finally responds, it accelerates quickly, which could cause me to lose control or collide with another vehicle. Safety Concern: This malfunction creates a significant safety risk. It puts myself, passengers, and other drivers in danger when the vehicle fails to accelerate as expected in high-risk scenarios such as crossing intersections, merging into traffic, or making left turns. The hesitation can leave the vehicle exposed in traffic, and the sudden lurch forward can cause unintended movement or rear-end collisions. Status: The problem has occurred multiple times under similar conditions and is ongoing. It has not yet been inspected or confirmed by a dealer or service center, but I have an apt Aug 24th. However, the malfunction is real, reproducible, and presents a serious hazard that could lead to an accident if not corrected. Many others with the same vehicle have expressed the same concern as well on forums and reported no fix after dealership appointments.

I've had consistent issues with the vehicle accelerating and shifting. These include sluggish acceleration, loss of power, sputtering, and limp mode. We've almost been hit by other vehicles almost 10 times because the vehicle has failed to accelerate when pulling into a roadway. The vehicle will start to accelerate slowly, then stop, then 5-10 seconds later will surge forward will the engine revs very high and is delayed shifting into 2nd gear. I've told my Toyota dealership about this numerous times but they keep telling me that there's no issue but there clearly is being that many others are experiencing the same exact problems. There's never been a warning lamp or message when this happens. This is a huge safety issue and my family is extremely lucky that we haven't been involved in a serious accident.

*Acceleration lag from a stop On June 21, 2025 - 92 degrees outside leaving store, I was making a left turn from a parking lot. I took my foot off the brake to creep forward which the vehicle did, but as I pressed the gas the car would not accelerate. I was stuck in the middle of the lanes with my car coasting. Fortunately it was a quiet street and the car coming from behind me had ample time to stop until i could coast my car to the side of the road which then it revved high and engaged. It felt like the car was in neutral but it was in drive. It lasted about 5 seconds. *It would not accelerate which was scary and very dangerous for obvious reasons. * I took the car to the dealership on the next business day and unfortunately cannot have it inspected until July 15, 2025. *No warning lamps, messages or other symptoms. *My car is available for inspection. That would be great! That’s why I brought it to the dealer but they were booked. *It happened only once, but I haven’t driven it much since the incident. I am now driving my 20 yr old, reliable MDX until I can get it inspected on July 15th

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.

Engine failed to engage while trying to pull out of my neighborhood this morning. The electric motor starts and propels the car forward into the road, but the gas motor fails to engage leaving me in the middle of the road without the ability to maneuver. This is a recurring problem. The dealer is aware of it and I have made reports here before. Just documenting each time until Toyota cooperates and helps find a solution. The car does not display any error codes. When I call the dealership to tell them and hopefully go in to have them run a diagnostic they consistently fail to get back to me or downplay my concerns.

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.

Car will not accelerate immediately from a stop; seems to happen more often when on a slight incline. This poses a safety issue when pulling out onto any road. I have asked multiple times at the dealer about and been told they cannot do anything about it unless the car gives a code. They also say it will not reproduce for them, although every time I pull out of their service location (with a slight incline) it stalls out and will not engage immediately for me.
