Toyota Grand Highlander

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,…

I haven’t had no accident in my car

On occasion the car will not accelerate from a dead stop like it should. I think it’s turbo lag. There have been a few times I thought I was going be broadsided pulling out into traffic when normal acceleration would have been safe but with a dead pedal for a few seconds it was terrifying. I’ve brought this up to two different dealers and they say without being able to experience it there’s nothing they can do. Someone going to die because of this.

After coming to a complete stop at a stop sign or stop light, then trying to go, the vehicle will stall. It will not go when given gas. The first time it happened, I was at a busy intersection with oncoming traffic coming towards me with the pedal to the floor, nothing would happen for 5-10 seconds. It was terrifying. Thank god the car coming towards us went around in time. It then happened again in my neighborhood a week later. Thankfully that time I wasn’t in traffic. I have noted that it…

This vehicle has just over 18,000 miles on it and is 14 months old. It has a manufacturer design defect that allows small stones or birds to hit and puncture the air conditioning condenser. It is a known defect and Toyota refuses to warranty their product, forcing the consumer to pay out of pocket $1,500-$1,700 for repairs. Oddly, the sister Lexus vehicle has a screen over the condenser to prevent this.

Radiator issue summer of 2025, when in back to back traffic at low speeds my vehicle overheated at a stand still took vehicle in to dealership with no real answers. The following summer 2026 same scenario but the engine was smoking. Took into dealership and they stated the connection for the radiator fan was disconnected which meant it was not colling the engine. A month later the AC is blowing hot air when AC is set to the coolest setting, scheduled another appt with dealership likely another…

The passenger-side second-row bench seat (60 percent section of the 60/40 split) has a defective seat track/latch assembly that fails in both directions: it seizes completely when it should slide, and it failed to stay latched while the vehicle was in motion. The seat saw almost no use for the first 34 months of ownership (third row kept folded). Within two weeks of its first regular use (XXX, approx. 45,700 miles), it seized completely and could not be moved in either direction. An authorized…

Driving down the highway and the sunroof exploded

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…
