October 27, 2026Unknown or Other
The front panel of the two-panel glass moonroof spontaneously shattered, buckled and collapsed onto the panoramic roof sunshade of my 2025 Toyota Grand Highlander Hybrid without any impact or accident. I was driving at about 35-45 mph on a paved road and noticed the sound of wind coming from the car ceiling. I opened the panoramic roof sunshade slightly to see if the moonroof was open and saw that the front panel of the two-panel glass moonroof had spontaneously shattered. By the time I got home about an hour later, the moonroof glass had buckled about 1/2 inch into the air and a large chunk of the moonroof glass had collapsed onto the sunshade on the ceiling of the car. I now have a 6x10-in

Experienced repeated axle issues, acceleration hesitation, and poor suspension performance. Dealer failed to identify or reproduce the problem despite multiple visits and diagnostic fees. Axles eventually required out-of-pocket replacement due to popping and clicking. Suspected axle defect persists, and the vehicle remains unsafe-feeling and unresolved. Requesting Toyota investigate and provide free repairs.
October 15, 2026Fuel/Propulsion System
The vehicle exhibits abnormal fuel system behavior. When the vehicle reaches a low fuel condition (approximately 40–50 miles to empty), the fuel tank only accepts about 12 gallons, even though the listed tank capacity is 17.2 gallons. After refueling, the fuel gauge displays FULL and the “Distance to Empty” reading jumps to over 360 miles, which is inconsistent with the amount of fuel added. A Toyota dealer documented this behavior on a repair order, stating that the tank accepted only 12 gallons from a low fuel condition and immediately displayed a range of 363 miles. A second repair order states that the fuel system was inspected and that the tank supposedly has a “3–5 gallon reserve,” but
October 13, 2026SteeringWheelsLane Departure
I experienced a serious safety incident involving my 2025 Toyota Grand Highlander with approximately 14,000 miles. While driving on a straight interstate highway at approximately 70 mph, surrounded by other vehicles, the steering wheel suddenly made two to three sharp, forceful jerking movements to the left. Afterward, the steering wheel remained approximately 20 degrees off-center to the left. All lane departure assistance sensors were active during the incident. This unexpected steering behavior created a significant safety hazard. At highway speed, I could have lost control of the vehicle, departed my lane, or collided with surrounding traffic. I was able to reach my destination, but the

On 9/26 at about 10:15am, my husband and I were fully stopped at a red light with his foot on the brake. Without him touching the gas pedal, the car suddenly surged forward as if it had been accelerated. It stopped for a moment, then surged forward again. Because he was holding the brake, the car didn’t move much, but each surge caused a hard jolt that felt like being rear-ended. No other vehicle hit us.
