Battery & propulsion complaint analysis for the 2024-2025 Toyota Grand Highlander
That's about 1.9x the typical rate for hybrids in this dataset (median 7.1 per year). Above peer average — but high-volume models naturally produce more raw complaints, so check the issue mix below before drawing conclusions.
What kind of battery complaint?
Among the 27 battery-related complaints, here's the type mix. These percentages describe what the complaints are about — not how reliable the vehicle is overall.

Sample complaint excerpts
Electric Propulsion
- [2024] The hybrid inverter cooler failed due to an impact with what was described as a rock or road debris shooting through the front grill and striking the inverter cooler so that it leaked coolant and failed. There was no notice of impact, while driving on the highway the hybrid system rapidly went into shut down/safety mode and acceleration and power to the drivetrain of vehicle dramatically reduced
- [2024] During driving on a highway at highway speed (not off-roading), A road debris or rock went through the front grille's hole and damaged the cooling system which leaked coolant and i experienced a loss of power and propulsion while driving on highway, as a result of this issue.
- [2024] 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 someon
Hybrid Drivetrain

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
- [2024] While driving my 2024 Toyota Grand Highlander Hybrid AWD at highway speed with only 16,755 miles on the vehicle, multiple warning messages suddenly appeared, including warnings related to the engine, hybrid system, AWD system, and other vehicle functions. The vehicle instructed me to pull over immediately and significantly reduced power output, making it difficult to maintain highway speed and saf
Thermal Events
- [2024] On 11/24/25 I gave permission to my friend to drive my 2024 Toyota Grand Highlander SUV from my house to Newark international airport, while my friend was driving my 2024 Toyota Grand Highlander SUV on a New Jersey Turnpike , the vehicle suddenly dropped the speed and within moments caught fire. I live in Pennsylvania, but the incident occurred on New Jersey Turnpike . The fire started while the c
High-Voltage Battery
- [2025] Shortly after powering on the GHHM vehicle, driving a short distance, coming to a stop and depressing the accelerator the vehicle does not accelerate as though no power is getting to the drive train. This does not often happen but has always happened when the EV battery level is 3 bars or less and the vehicle is in its Normal mode (as opposed to Sport or ECO). This acceleration failure event last
Source: classified from NHTSA complaint and recall data. "Battery-related" includes high-voltage propulsion battery, charging system, hybrid drivetrain, electric propulsion, regenerative braking, 12V auxiliary battery, and thermal-event complaints. Other complaints (suspension, steering, brakes, infotainment) appear in the engine and vehicle-level sections. Rates are absolute counts, not normalized per-VIN — high-volume models naturally produce more raw complaints than low-volume ones. Self-reported death and injury counts are capped per complaint to limit form abuse.
