2024 Toyota Grand Highlander

I own a 2024 Toyota Grand Highlander Hybrid MAX Platinum, purchased brand new in February 2024 and now with approximately 30,400 miles. Since the first few weeks, the vehicle has had an ongoing fuel tank/range issue. 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 vehicle reports the tank as full and but generally shows only 270–290 miles of estimated range. The actual miles driven before requiring fill up is 230-250 miles. Toyota issued T-SB-0060-25 (Low Fuel Warning Light Logic Enhancement), which a Toyota dealer reluctantly performed on my vehicle. It initially improved the displayed range by only about 10 miles, but did not resolve the problem, and the condition is now worsening. The dealer solution was to tell me I can drive another 60-100 miles past empty but I do not believe that is a reasonable or safe workaround. This is because the driver cannot reliably determine the remaining usable fuel or how far the vehicle can safely travel. The condition remains unresolved and is a known issue with other Toyota Grand Highlander Hybrid Max owners.

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. The engine seemed to minimally climb in RPM and only accelerated minimally out into the cross road. This lasted approximately 1-2 seconds. AT this point I was fully into the first lane of traffic. I then fully depressed the accelerator to try to get the vehicle to respond and after approximately a 0.5 to 1.0 second delay the engine fully responded and I was able to accelerate out of the oncoming cross traffic. This is by no-means the first time this behavior has happened with this vehicle but it is the first time I'm reporting it to the NHTSA.

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 fuel is the cause without further inspection. At this time, I have not been given a specific diagnosis identifying a failed component or confirming that a particular fuel-system component is malfunctioning. The vehicle is available for further inspection if requested. The strong gasoline odor raises a safety concern because the presence of fuel vapors could potentially indicate a fuel leak or another problem with the fuel system, creating a possible fire hazard. The problem was reported to and inspected by Fox Toyota in El Paso, but the dealership attributed the odor to the ethanol content of the fuel rather than identifying a defective component. I have not had the vehicle inspected by the manufacturer or any other independent facility at this time. I have not observed any warning lights or warning messages associated with the problem. The primary symptom has been the strong gasoline smell. The vehicle has the 2.4L turbo engine. I would like to know if other 2024 Grand Highlander 2.4L turbo owners have experienced the same issue and, if so, what the actual cause was and how it was resolved.

While driving on a highway at highway speed of approximately 62 miles per hour, a rock from the highway went through the front grille's hole, and punctured the area of the radiator, resulted in a large loss of coolant, and the vehicle's speed suddenly lost highway speed and lost propulsion on the highway, while driving at a highway speed. Thankfully noone was driving behind me. However, If someone was behind me, they would have hit me from the rear due to my loss of propulsion.

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, The RPMs get extremely high while the car is going 25-40 mph and remain there for a few seconds up to ~20 seconds. I am fearful of getting t-boned when my car hesitates while turning at an intersection, going through an intersection or pulling out from a parking lot. I have been stuck in several intersections when traffic was coming toward me, but thankfully those cars had patience and avoided us. I've also found that this issue always happens when the hybrid battery shows that it only has a charge of 3 bars. It seems that the engine, transmission and hybrid battery don't know how to communicate when the battery charge gets that low. This has been happening since Dec 2023 when I bought the vehicle and the dealer has never been able to duplicate or find any error code, they are refusing to fix a known issue when many others are experiencing the same issue. There are Toyota Technical Service Bulletins (TSBs) out there regarding this problem but my dealer told me they won't do anything as it could label my vehicle a lemon. This is creating an unnecessary safety risk for me and my family.

On a recent road trip I experience loss of acceleration twice. I was at a stop sign making a left hand turn. I step on the accelerator it start forward but then stop suddenly leaving me in the 1st lane of on coming traffic. I smashed on the accelerator several time before the vehicle finally responded. I took the vehicle to the dealer on 6/30 told the dealer what had happen along with my google findings acceleration hesitation and sudden lurching in the Toyota Grand Highlander Hybrid MAX Technical Service Bulletins (TSBs), including T-SB-0017-24. The dealer could not duplicate or find any error code, they are refusing to fix a known issue. They are creating an unnecessary safety risk for me and my family.
