The fuel tank is rated at approximately 17 gallons, but the gas pump consistently shuts off after only 10–12 gallons, even when the vehicle indicates 0 miles to empty. It accepts approximately the same amount whether I refuel with 80, 20, or 0 miles remaining. After filling, the veh…”

• “At 5:16 pm, CST. I was stopped at a stop sign headed west on a 25 mph road crossing a 30 mph road (that does not have a stop sign) in Illinois. After waiting for a an appropriate gap in traffic, I attempted to accelerate though the interesting. I released the brake pedal and attempted to accelerate. The vehicle barely accelerated.

• “I currently own a 2024 Toyota Grand Highlander with the 2.4L turbo engine, which I purchased in July 2023. I have been experiencing a strong gasoline/fuel smell coming from the vehicle. I took the vehicle to Fox Toyota in El Paso for inspection. According to the dealership, the smell was caused by the gasoline I was using and they stated that the fuel contained too much ethanol. However, the gasoline smell was strong enough to be concerning, and I am not comfortable simply assuming that the fue…”

• “The car stalled on entering secondary roads from my own neighborhood. When it happens, I have pressed the throttle and the car stops moving forward. It takes 5-10 seconds before the engine picks up and the car moves. The first owner found the same thing and now as the second owner, it has done the same thing.”

• “I've had consistent issues with the vehicle accelerating and shifting. These include sluggish acceleration, loss of power and sputtering when we've come to a complete stop and starting to move again. We've almost been hit by other vehicles at least over 20 times because the vehicle has failed to accelerate when pulling into a roadway. The car hesitates during acceleration regardless of how much I push the gas. Once it starts to go, it feels as though the car can't shift from 1st to 2nd gear, Th…”
