The car stalls or fails to accelerate from a complete stop despite adequately stepping on the gas pedal. This has left me in dangerous situations with oncoming cars as my car fails to move as expected. This issue occurs sporadically.

- Vehicle intermittently will not respond or will barely respond when accelerator is depressed from a complete stop or near (rolling) stop. I have noticed this issue mainly when A/C is on high and during hot temperatures. I reside in the Phoenix, AZ area where high temperatures have been ranging around 110-115. - This poses a safety risk when attempting to pull out onto a busy road, either turning left or right. If the gas pedal fails to respond, this could lead to a serious crash. - This issue has arisen following a recent software update that Toyota performed (under service bulletin TSB-0017-24). This update was done to correct a different issue (shifting hesitation between gears when accelerating from 0-40mph), however it seems to have negatively affected the response of the vehicle when starting up from a stop. I have not yet taken my vehicle back to Toyota with this issue, but MANY owners of the HybridMAX are experiencing this same issue as the weather temperatures have peaked. - No warning lights appear when this occurs. The problem arose shortly after I had a software update done at the dealer on June 14, 2024.

while the engine has not warmed up, when its hot and air conditioning is on high, vehicle does not respond to the gas pedal while trying to accelerate from a stop. vehicle hesitates on acceleration. i feel this is a safety problem, because i need the car to merge quickly onto the road from a stop. this hesitation could cause a bad accident. i feel like the hesitation, is the car trying to find the gear.

When accelerating from a stop, there is a hesitation or lack of power when stepping on the accelerator. Releasing the accelerator and depressing it again will get the car going. The engine also revs high at low speeds before dropping to the next gear.

The vehicle randomly won’t go when starting out from a complete stop. You can push the gas pedal to the floor and it will barely move. Almost got hit in an intersection trying to make a left turn. Toyota is aware of the problem and has a TSB and did an ECM update but the problem persists. It’s scary when it happens. Can’t trust the vehicle.

1. Transmission issues with slippage, response. Issues where when going from reverse into drive taking 2-3 seconds to engage. Issues coming from a stop to going as well whereas there’s a hesitation with propulsion. 2. Safety has been at risk numerous times when pulling into heavily trafficked areas. Response to pedal should not have a 1-2 second hesitation, but it does and it’s sporadic. Can no longer back into locations where it may be important to put it into drive and move fast, a 3 second delay is a long time when you’re not moving and someone is going 50mph in a 35. 3. Dealer reproduced the delay from reverse to drive and annotated it was “normal” behavior. 4. Dealer denies issues with transmission, brought to another where they said it was a CVT and that’s just how they are and master tech came for drive with me. He was wrong, XLE is not a CVT. They flashed it/reset it. Seemed to help with shifting issues, however it did not fix delays. 5. No warning lamps.

**Vehicle:** Toyota Grand Highlander Hybrid Max **Issue:** On high-temperature days, when the A/C is running at full capacity, the vehicle occasionally fails to accelerate from a stop. This issue persists even after applying the recommended ECM update. **Safety Concern:** The lack of reliable acceleration poses a significant safety risk, particularly when turning across oncoming traffic or entering a busy street. This situation can leave the vehicle stalled in the path of approaching vehicles, increasing the likelihood of an accident. **Action Taken:** Applied the ECM update that is supposed to resolve the issue, but the problem persists.

Starting off from a stop or at low speeds the vehicle loses all power. Engine stumbles and does not respond, when it happens it almost feels like the engine may stall. Pressing the accelerator and the vehicle will not move, then suddenly will start to go seconds later. This has almost resulted in a crash since the vehicle loses all propulsion unexpectedly. No warning lights. Took to the dealer twice and everything is “normal” no codes stored.

There is a huge hole in the undercarriage starting at the back of the vehicle and runs all the way to the front of the vehicle. Hole is large enough a child can climb in without anyone knowing and could possibly die if car is in motion.

Our vehicle loses power after initial startup when you first accelerate. We have had three incidents where we were pulling out from a stop sign or stoplight on a major road and you press the gas and the car shutters and doesn’t move at all. All three times a car accident almost occurred. This has been reported to the dealer and they replaced the entire hybrid powertrain. The issue persists at random with no warning messages generated by the car. It also hasn’t been replicated for a dealer to see themselves. It’s extremely dangerous and has been reported numerous times on forums.

Fuel tank is 17.2 gallons. Refueling on empty only can put in max at 12 gallons when fueling tank is full or stopped. Have never been able to put more than 13 gallons in this tank. Has taken the car to dealer for checking, they came back and said the tank was a 17 gallon tank.

The fuel tank capacity according to the vehicle specifications should be 17gallons. I have refilled the vehicle three times after reaching empty (around 20mi left according to the gauge), and when I fill the tank it only takes about 11 gallons to fill. That is a significant difference. Even with a reserve, I should be putting around 15 gallons in the tank when it is on empty to fill it. I am concerned that the tank is not the correct size or there is a problem with the fuel level sensor.

Subject: NHTSA Complaint - 2024 Grand Highlander Hybrid XLE Rear Windshield Shattering To Whom It May Concern, I am writing to formally file a complaint regarding a concerning incident with my recently purchased 2024 Grand Highlander Hybrid XLE. On [XXX], 2024, the rear windshield/liftgate glass spontaneously shattered without any apparent cause. The vehicle was merely six months old at the time of the incident. This unexpected and potentially hazardous occurrence has prompted me to investigate further, and I have come across multiple reports online from other customers who have experienced similar issues with the same rear windshield/liftgate glass on this specific vehicle model. This pattern of incidents raises significant concerns about a potential manufacturer's defect that may compromise the safety and reliability of these vehicles. Given the frequency of such occurrences and the potential safety implications involved, I am urging the National Highway Traffic Safety Administration (NHTSA) to investigate this matter thoroughly. It is imperative to identify any underlying issues or defects that may be contributing to these incidents to ensure the safety of consumers and prevent any potential accidents or injuries in the future. Please consider this complaint as an urgent matter, and I implore the NHTSA to take appropriate action to address this issue promptly. Your attention to this matter is greatly appreciated, and I look forward to a swift and comprehensive investigation into this concerning issue. Sincerely, [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

At speeds under 30 mph cabin air pressure builds in the cabin and creates a bass sound or “cabin boom”. The pressure hurts occupant ears as well and has made them sick after riding in the vehicle. This is a well known issue with the Grand Highlander. Toyota has not offered any acknowledgment or a fix.

Sometimes the radio lose volume all the way. You could turn the volume all the way up , change stations, FM, Sirius and nothing happens. The only way that this issue goes away and you can go back and start listening is to turn off completely the vehicle, leave if off, for a few secs, then power on . turn on the vehicle. This is very annoying since if you are driving for a long period of time, you cannot turn off the vehicle to do this trick. I hope this 3.0 Toyota Multimedia works better and more reliable.
