UNKNOWN OR OTHER
Multiple times a week in the summer my car will hesitate to go once I have stopped at a stop sign/busy four way intersection. When I push the gas the car doesn’t respond and hesitates for a long while before I can get the car to start moving again. The car will roll into the intersection after I take my foot off the break to go and it won’t do anything. It is terrifying and confuses other drivers around me thinking that I am letting them go. This has happened upwards of 20 times since I have had the car. It happens only on hot days when the external temperature is above 80 or so degrees and happens when car is freshly started. It reliably happens when I go up a pretty small hill by my house about 1 minute after starting the car (even when it is coming from being parked in my garage). Joseph Toyota on Colerain in Cincinnati has not been able to reproduce the issue. I drive with two children in the car and it is so scary when it happens because I have almost been hit with them in the car many times now.

FUEL/PROPULSION SYSTEM
The car stalled on entering secondary roads from my own neighborhood. When it happens, I have pressed the throttle and the car stops moving forward. It takes 5-10 seconds before the engine picks up and the car moves. The first owner found the same thing and now as the second owner, it has done the same thing.

POWER TRAIN, ENGINE, VEHICLE SPEED CONTROL
Sometimes, when trying to accelerate in certain situations, the vehicle accelerator pedal will not respond or the engine stutters and won't immediately respond to input and the vehicle seems to stall. This has been scary several times in traffic. The vehicle originally would throw an engine code on the dash about system failure and was taken into the dealer after several of these incidents and a software updates was performed, but it still happens randomly although now with no code.

STRUCTURE:BODY, UNKNOWN OR OTHER
Damage occurred to the front air conditioning system because a rock flew through the open grill area. This punctured the system causing a couple thousand dollar repair, not under warranty. The car was nearly brand new at the time. The grill area is a problem, it's a bad design.

ENGINE
The engine would not engage for 4-5 seconds when pulling out of my neighborhood. Gas pedal was all the way down and after a delay, the car rolled forward as if trying to start in 2nd/3rd gear. I am a cautious driver, but this is an unsafe scenario when pulling out into traffic.

STRUCTURE:BODY
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. This took a matter of seconds while on the highway without any warning. The problem, cause, effect, and repair was all diagnosed by a Toyota service personnel at a Toyota dealer. It was reported that this is a common issue with the grill design.

ENGINE, FUEL/PROPULSION SYSTEM
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.

A rock went through the grill and pierced the AC condenser. The result left us with no AC. Toyota of Grand Rapids charged us $2300 to replace it. The holes in the grill are massive. Toyota of Grand Rapids has a video on file documenting the issue.

UNKNOWN OR OTHER
Road debris from normal driving on paved roads (perhaps related to a trip from Flagstaff to Phoenix on [XXX] in April 2026- in Phoenix the AC took a very long time to cool down the car), road debris punctured the ac condenser. The AC stopped working entirely in July of 2026, so it was taken to Findlay Toyota Flagstaff for review. They noted all refrigerant had leaked from the system, and that road debris had punctured the condenser. The warranty claim was denied, and I paid about $1450 out of pocket for a new condenser and system recharge. I have the estimate from the dealer along with the receipt for the actual repair; however, the file upload functionality of this app is not working.

FUEL SYSTEM, GASOLINE
The contact owns a 2024 Toyota Grand Highlander. The contact stated that while driving at an undisclosed speed, there was an abnormally strong gasoline odor inside the cabin of the vehicle. The contact believed that the odor was caused by a fuel leak. The vehicle was taken to a dealer, where it was diagnosed with an evaporator filter failure, and it was determined that a fuel leak was not the cause of the odor. The dealer stated that the vehicle did not require a repair and could still be driven with the odor inside the vehicle. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 45,000.

WHEELS
I have a 2024 Toyota Grand Highlander (FWD Gas) with about 37,000 miles and had 2 wheel bearings fail - front right and rear right. I noticed a constant humming noise starting around 20-25 mph that increased with vehicle speed. Thinking it was tire noise, I replaced all 4 tires, and the sound was still present. The dealership first replaced the right front bearing, and when they drove it after the repair, they noticed the sound decreased but did not eliminate the noise, and they further diagnosed a failed rear wheel bearing.

POWER TRAIN
My vehicle has a recurrent issue with failing front axle assemblies. The vehicle experienced rotational clicking and had both from axle assemblies replaced around 20,000 miles. Around 40,000 miles the clicking returned and toyota has refused to replace the failing axles again. I currently am at 63,000 miles and I won an arbitration case regarding the axles. The arbitration decision ordered toyota to replace the axles and determined that the parts were defective and covered under warranty. Toyota breached the arbitration and refused to replace the defective axles as ordered in a legally binding arbitration. Rotational clicking is more apparent at low ambient temperatures. A metallic grinding is more apparent at high ambient temperatures. I have had several drive train skips, a sensation of drive train parts slipping and slamming together. Toyota knowingly put defective parts back on my car during the 20,000 mile repair. Toyota release a technical service bulletin T-SB-0082-24 in sep of 2024. It stated that they redesigned the axle to fix the problem. The tsb said to put the original part number on instead of the updated, fixed part number. I received the old, broken part number when my repair was done in 2025. There is a new bulletin T-SB-0028-26 release in april 2026 for the same issue and it states that the previous bulletin is obsolete. The new bulletin states that the correct part number is the new part number not the old one. Additionally, the tsb indicates toyota changed to the new part number with a vin cutoff sometime in 2024. The fixed part number was changed at the production line level in 2024 yet I received the old, known defective part. These are drive axles and a failure can lead to loss of control and a serious accident. A full investigation and recall of this part should be conducted.

SERVICE BRAKES, HYDRAULIC
The contact owns a 2024 Toyota Grand Highlander. The contact stated that the vehicle unexpectedly lurched forward while depressing the brake pedal. There was no warning light illuminated. The contact stated that excessive pressure was needed on the brake pedal to prevent the failure. The contact stated that a service appointment was scheduled with the dealer. While conducting independent research, the contact identified Technical Service Bulletin: T-SB-0028-25, which was associated with the vehicle shuddering while at a complete stop, and believed that the failure was associated with the technical service bulletin. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 39,000.
