IllustrationMultiple times I have pressed the gas pedal and the car has not responded, as in did not accelerate. I was almost T-boned one time because of it since I was turning left and could not accelerate above 5mph. This is a frequent issue among GH Hybrids from talking to others.

- 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.

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.

1DP26006 · Road Debris/rocks Damaging The Heat Exchangers
Opened Aug 20, 2026 · No close date supplied
Status: open (inferred from source dates) · Engine And Engine Cooling:cooling System
The Office of Defects Investigation (ODI) received a Petition dated July 20, 2026. The Petition requests an investigation of road debris / rocks damaging the heat exchangers in model year (MY) 2024-2026 Toyota Grand Highlander vehicles. The Petition contends that the Grand Highlander’s front-end grill has large, open apertures and no protective screen between the grill and the vehicle’s heat exchangers. The Petition further alleges that as a result, during normal driving, the damage to heat exchangers results in coolant leakage and sudden loss of propulsion. The Petitioner cites thirteen (13) complaints received by ODI alleging this failure, which, when added to the petitioner’s own complaint, bring the total under consideration at this time to fourteen (14). ODI will evaluate these complaints to determine if they are related to the failure cited in the Petition and conduct a technical review under 49 CFR Part 552. This Defect Petition is being opened to evaluate whether to grant or deny the petition. The petition can be reviewed at NHTSA.gov under ODI number 11754975.
