**Vehicle:** 2026 Toyota 4Runner SR5- -700Miles I am reporting a persistent vibration issue that appears to come from the engine bay and is transmitted through the driver's side floorboard into the driver's left foot and leg. The vibration is most noticeable when the transmission is engaged and the vehicle is under load. If the transmission is disengaged while the vehicle is still moving, the vibration disappears, even though the driveshaft, axles, and other drivetrain components are still rotating. This suggests the issue may be related to the engine or transmission rather than the tires or other rotating components. My daily one-way commute is approximately 30 minutes. By the time I…

The Toyota 4Runner (5th and 6th Generations) lacks a dedicated 'Approach Lighting' function, creating a critical personal safety and trip-and-fall hazard during nighttime entry. Users are forced to navigate the vehicle's perimeter in total darkness, increasing the risk of injury from unseen obstacles or security threats. I am requesting an investigation into this lighting logic omission and a remedy via a software update to the Lighting Control Module to ensure owner safety for all generations of the 4Runner platform.

At approximately 520 miles, while performing a low speed left hand turn, the vehicle experienced a sudden mechanical "thunk" in the drivetrain followed by an immediate loss of motive power (Limp Mode) in my new 2026 Toyota 4Runner TRD Pro. The engine revved significantly, but the vehicle failed to accelerate as intended, creating a hazardous situation in the intersection of oncoming traffic. A diagnostic health check at an authorized dealer confirmed stored DTC fault codes P281671 and P08BA71, indicating that Pressure Control Solenoids Actuators "H" and "L" were in a "stuck" state. The vehicle's Freeze Frame Data recorded a catastrophic internal transmission slip, showing an engine speed of…

The car has the iforce max powertrain. At low speeds or in stop and go traffic, when the car has come to a stop, the car will lurch forward, which could potentially cause an accident. I took car to dealership and they said this is normal operation of the hybrid system and there is no fix. This is a huge safety issue if the car pushes itself forward and potentially causing an accident. The transmission system is very unrefined.
