2025 Toyota Grand Highlander Complaint Log

We have two forward facing car seats in the third row. When buckled according to the car seat user manuals - the seatbelts do not stay buckled. The seatbelts unbuckle while driving, creating an extremely dangerous situation for our toddlers. We take out and redo their car seats daily due to them being unbuckled while the vehicle is in motion. Our toddlers are not able to unbuckle them - so we know it is a vehicle defect. The car has been taken to the dealership where they simply tell us they can’t find an issue. We do not feel safe in this vehicle and do not want our children in there. No safety lights appear on the dash to notify us that the seats have become unbuckled.

Driving when it sounded like a gunshot went off in the car. I looked to the back of my car to see what was around me (nothing), and saw no damage to any windows. I could hear glass cracking so I went to open my moonroof screen to check the glass and I could hear glass on the screen so I closed it right back. I pulled over and was able to confirm the sunroof had busted across the back of the glass. It did not look like it was hit by anything, but like it blew out then spidered across the remainder of the glass.

Sunroof spontaneously exploded leaving an 8” hole and a completely shattered sunroof. The sunroof is flexed upwards like it was under extreme pressure. The high temperature was 70 degrees in Tuscaloosa today with cloudy skies and misty rain. So there shouldn’t have been any concerns from heat or cold. This left shattered glass every above the sunshade. Fortunately the shade was closed to catch most of the shattered glass.

Transmission slipping, holding high RPM, Jerky shifts, back seat not locking at times, infotainment freezing up

Due to the design of the grill located at the front end of the 2025 toyota grand highlander the vehicle poses vulnerability for multiple debris items to fly up into exposed air conditioning condensor. The damage caused by the debris is not covered by the warranty because it is considered an outside occurrence. However the design creates the vulnerability for the ac to become damaged. It is also sitting below the radiator posing an additonal risk for damage and should have additonal protection to help prevent damage. I am currently having to dispute the refusal to cover the damage to my own ac condensor done by a rock flying into the grill space causing damage and losing freon, because they state it is an outside occurrence regardless of the fact that the design is faulty. There are multiple people who have experienced this happening to their vehicles some not even at the 2000 mile mark and are responsible for the financial cost. Upon doing research the 2026 toyota grand highlander model was created with an even lower setting bumper that provides better coverage and protection for the air conditioning condensor and all other important mechanical components. Suggesting that Toyota is aware of the issue if they created an additonal part to help protect that area from damage. I am literally at risk each time I drive my car just for the fact that rocks are on every road way as well as other debris. I have called the customer relations department with no resolution given only to be told I am responsible for the cost of the repair. I believe this is something that needs to be addressed as well as fixed for the sake of the buyer and the already large cost of owning and maintaining a vehicle. If it happens more than a few times its not bad luck, it's a flaw in the creation of the product and consumers should not have to be held financially responsible for someone else mistake, whether individual or corporate entity. I have previously owned 4 other toyotas with no issues!

The front panel of the sunroof shattered while the vehicle was parked in our garage. Glass shards are inside the car. The dealership submitted a claim to Toyota who denied any material defect and refused to repair under warranty.

outside temperature reading is 2 to 7 degrees high, which is not good when it makes the difference between freezing temps and not freezing temps

At a complete stop my car started shaking violently back and forth. It felt like we were in an earthquake. It has happened before but not as violently and not as long. No warning lights or anything. It has had problems with lurching and stuttering since we bought it. The dealership said they fixed it once (the stuttering) but it’s still happening. They cannot duplicate it and it’s not throwing any codes.

Dear National Highway Traffic Safety Administration, I am submitting this complaint to formally report a serious safety issue involving the left front axle of my Toyota Grand Highlander Hybrid XLE. The vehicle was first diagnosed by my local Toyota dealer on January 14, 2026, at which time the left front axle issue was identified. I contacted **Toyota Motor Corporation**, and I was initially informed that the required replacement part would arrive on February 6, 2026. After that date passed, I was told the part would arrive in early March. I have now been told it will not arrive until late March. Based on these repeated delays, I am concerned that “late March” could easily become late April or even later, with no firm commitment or guaranteed repair date. I have contacted Toyota dealership multiple times and made several phone calls seeking assistance, updates, or a definitive timeline. Unfortunately, no one has been able to provide a clear solution, firm delivery date, or alternative support while the part remains on back order. Due to the axle issue, I do not feel safe operating the vehicle, as I believe it presents a significant safety risk. This vehicle is essential for my work and daily financial responsibilities. Because I do not feel it is safe to drive, I am unable to use the car to earn my day-to-day income and meet my financial obligations. As a result, I am currently losing wages, and the prolonged delay is causing financial hardship and significant inconvenience. Given the safety implications and the ongoing lack of resolution, I respectfully request that the National Highway Traffic Safety Administration review this matter. I would appreciate guidance on the appropriate next steps, including whether this issue warrants further investigation, inspection, or potential recall action. I also seek clarification regarding what protections or remedies may be available to consumers when critical safety components are unavailable for extended periods.

The car was running perfect, 9 months after I bought this car, before 20,000 miles Front Left Axle become defective, and therefore, the dealer promised to reemplaced it, but I am still waiting from the dealer. It is a big risk to runs the car like that.

2025 Toyota Grand Highlander Hybrid AWD, with about 16000 miles. While driving, the brakes failed. The brakes would only work if the pedal was pushed all the way to the floor. A "Low Brake Power" warning light came on the dash. The following warnings came on at the same time. Parking Brake System, Advanced Ultrasonic Detection, Vehicle Stability Control, Check Engine, Smart Stop System, Brake System, Electronically controlled Brake, Secondary Collision Brake, Anti-lock Brake System. I was lucky to have been traveling on a road that was not busy and was traveling at less than 30 mph very close to my home. Had I been driving on the interstate, on a busy road, or near pedestrians, the event could have injured or killed myself, my family, or others. The car was towed into the dealership. The dealership said that the issue was not current and the car operated normally when after it was towed in. The following DTC codes where present (P05E000, P05E062). This indicates an issue in wiring or brake pedal stroke sensor. They suspect its an intermittent issue with the sensor. The sensor was replaced (P/N, 89510-0R010 and 62112-0E040-C1). They also said the car battery was low and replaced it (P/N 00544-H5061-540). The dealership said that they would send the affected part to Toyota for inspection, but I have not heard anything back. The dealership experience was poor (Mark Jacobson Toyota, Durham, NC).

While accelerating from low speeds and turning, the car exhibits a rotational clicking noise from one or both front drive shaft assemblies. Seems to be the identical issue noted in the 2024 Grand Highlander that was presumably fixed during later production lots (T-SB-0082-24). That issue was seemingly solved with driveshaft replacement. The dealer said they “could not duplicate” the issue; however, it happens often while I am driving the vehicle and others have reported it to the same dealer as well. It seems to be an existing related safety issue that the dealer, and potentially the manufacturer, are ignoring until we get past the warranty.

The vehicle takes an excessively long time to make heat, I know NHTSA only has requirements related to defrosting the windshield and it's clear Toyota is aware of the heating issue because they added an electronic defrost to be able to pass the defrost test. The vehicle when it is less than 20f outside takes 40+minutes to warm the cabin to a reasonable temperature. The dealership let the vehicle warm up in their 80deg F shop and said it took 20minutes to get heat out of the vents and claimed that this was normal behavior. I have owned several new cars and also work as an engineer in testing so I've driven countless new vehicles to do various tests and have never had it even take 20 minutes to have heat in a vehicle.

While driving under normal conditions, the air conditioning system in my Toyota Grand Highlander suddenly stopped working. The vehicle was inspected by a Toyota dealership, which determined that the AC condenser had a hole/puncture that caused a refrigerant leak and complete AC failure. Toyota denied warranty coverage, classifying the damage as “road hazard,” despite acknowledging that this is a common issue with the Grand Highlander. There was no collision, no unusual road event, and no warning prior to failure. The condenser appears to be positioned in a highly exposed and vulnerable location, allowing small road debris to puncture it easily. Based on discussions with the dealership and reports from other owners, this issue is occurring repeatedly and results in expensive repairs (approximately $1,500–$2,000). This appears to be a design-related vulnerability, not an isolated incident or abnormal use. A failure of the air conditioning system significantly impacts vehicle safety and operability, particularly in extreme heat conditions. I am reporting this issue to document a pattern of premature AC condenser failure in Toyota Grand Highlander vehicles and to request further investigation.

Inconsistently but on numerous occasions, this vehicle has experienced harsh shifting, hesitation, or jerking during low-speed acceleration (e.g., 20-40 mph) or gear engagement. This was a known and reported issue with the 2024 model for which Toyota provided a fix. They have not provided one for the 2025 models. This issue is a safety risk while driving because with the surge you feel you must quickly let off the pedal, and with the hesitation you let off the brake indicating you will move forward yet the vehicle doesn’t accelerate.

There is a coolant leak in the hybrid radiator caused by a puncture. When taken to the dealer, they said a rock must have punctured it. The dealer currently has the part. Me, my husband, and 2 children were driving on I-5 when the car stopped accelerating and a "hybrid malfucntion" code and "engine malfunction" code started flashing. Prior to this, there were no warnings. I was thankfully able to full over safely, but we were stuck on the side of I-5 for at least an hour waiting for a tow. I am reading online that this is an issue with the car and seems to be a design flaw. The gaps in the grill are too large, and there is no mesh or anything else behind the grill to protect the front end of the car.

On 11/02/2025 with the cruise at 55mph all glass closed. Heater on with no vehicles around, the sunroof exploded. It pushed up from the inside. With less than 9k miles on the vehicle. It took my dealer 8 days to look at it then Toyota denied the warranty. Then Quoted me over $2,100 to replace. This vehicle isn't safe to drive as told to me from the dealer.

While driving at approximately 50 MPH with no other vehicles around, there was a loud bang and then the sound of air. We identified that the panoramic sunroof had exploded. We pulled over immediately and took photos of the sunroof which at that time was shattered but intact. There was a clear bulge upward and no sign of impact from an outside force. We then continued driving to our home approximately another 40 miles, during that drive shards of glass flew onto the roadway leaving a hole in the sunroof of approximately 10-12 inches. We brought the vehicle to Toyota dealership for a warranty repair. Toyota refuses to cover under warranty, stating outside influence. I am confident there was no outside influence causing the glass to explode. The vehicle is a 2025 Grand Toyota Highlander Hybrid Limited with approximately 9000 miles on it, the incident happened on Nov 2nd. 2025 around noon. Weather was mild, 50-60 degrees F, no precipitation or severe winds.

The contact owns a 2025 Toyota Grand Highlander with an Evenflo Revolve 360 Slim car seat, Model Number: 36812470A, Manufactured Date: December 12, 2022, installed in the vehicle. The contact received notification of NHTSA Campaign Number: 25C010000 (Child Seat). The contact stated that while driving at an undisclosed speed with the child secured in the car seat, the contact became aware that there was an object in the child’s mouth. The contact pulled over to the side of the road and removed a foam piece from the child's mouth. The contact inspected the car seat and became aware that the foam was from the headrest. Medical attention was not needed. The manufacturer was not notified of the failure, but the contact stated that the manufacturer mailed tape to cover the exposed areas of the car seat.

The contact owns a 2025 Toyota Grand Highlander. The contact received notification of NHTSA Campaign Number: 25V744000 (Back Over Prevention); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was contacted and diagnosed the vehicle and determined that the camera had failed, and that the contact would be notified when the remedy was available. The contact stated that after leaving the vehicle with the dealer, the back over camera started to fail. The back over prevention camera no longer switched the screen for the camera while in reverse, but remained on the home screen or radio instead. The contact had not heard from the dealer regarding the parts availability for the repair. The manufacturer was not made aware of the failure. The failure mileage was approximately 29,000.

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 lasts for a few seconds. No warning indicators are displayed prior to, during or after this happens. The dealer checked the vehicle on 30AUG2025, was not able to reproduce, but applied a firmware update TSB-0040-25, which has not solved the problem. Took it back to dealer on 14OCT2025, but the dealer was again not able to reproduce the problem. It poses a safety risk when attempting to cross intersections or entering round-abouts and the vehicle can only move at a coasting speed instead of the expected normal acceleration.

Sun roof shattered unprovoked in 2 month old vehicle while driving slowly in parking lot. We didn't know what happened at first but then opened interior lining and the shattered glass fell into the cabin; nobody was hurt. when we took this to dealership, we were told this wasn't under warrantee and we had to get it fixed independently. I filed a complaint with Toyota Care but they denied covering cost to fix the shattered sun roof. We did not have the shattered sun roof inspected by anybody else but it has been fixed by glass shop.

Poor acceleration from 0 to 40. Vehicle will start shuttering at a dead stop. The engine has shut off once with this issue. It happened around 4800 miles.

Windshield is prone to cracks and chips. Experienced multiple chips/cracks going at various speeds with precaution to other vehicles.

The car only accepts 11-13 gallons of gas when refueling an empty tank despite the advertised 17.2 gallon capacity. I believe this is a fuel gauge or DTE system problem. I’ve seen many many similiar complaints on the forums. Fuel gauge issue could leave drivers stranded on the road.

I am told my 2025 Grand Highlander has a hole in the AC Condenser from "road debris" according to a Toyota dealership leading to no air conditioning. I've never taken the car off-roading. A simple google search shows that others are having this issue and are buying extra netting to protect it from happening again. I'm told I need to pay $1,800 to have this fixed when I haven't even had the car for a year. This seems like a design flaw that needs to be addressed.

Apparently, a rock flew into the front grill striking the radiator (which is located directly behind the grill) and put a hole in it. This caused fluid to leak and fortunately during a routine maintenance check (my first service) on 8/15/25, it was discovered. The car was deemed not safe to drive until repairs were made. I submitted it to my insurance company and they inspected it and verified the issue. The radiator was replaced by Toyota at the dealership where I purchased the vehicle. They said they heard of a few cases, but I went online and discovered several vehicles that had this happen. Apparently the grill on the new highlanders is the issue - it has wide openings and the radiator is directly behind it. I am purchasing a bra and some mesh to place behind the grill in order to prevent another incident. No warning lights or indicators came on and the dealership said it would've eventually when it got hot enough. Fortunately, most of my driving was local after the incident occurred so the vehicle didn't have time to overheat. I am thankful it was discovered before I was stranded.

I have experienced intermittent transmission issues. Specifically, the car often fails to shift gracefully from first gear, resulting in rough or hard shifts that are jarring and unsafe, particularly during acceleration or in stop-and-go traffic. On multiple occasions, the vehicle has refused to shift correctly, requiring me to pull over, turn the car completely off, and restart it to restore proper shifting functionality. This issue is not only inconvenient but also poses a significant safety risk, especially when merging into traffic or navigating busy roads. For a vehicle marketed as a reliable and family-friendly SUV, these transmission problems are unacceptable. The transmission issues have significantly undermined my confidence in the vehicle’s safety and reliability, particularly as I rely on it for family transportation. The need to pull over and restart the car to address shifting problems is not only inconvenient but also dangerous in certain driving conditions. Furthermore, the reports of similar issues among other owners indicate that these problems may persist without proper intervention from Toyota.

I am writing to report a serious issue with my 2025 Toyota Grand Highlander Hybrid (VIN: [XXX] ), purchased on [XXX] from Hillside Toyota . I have noticed water leaking from the top of the windshield, dripping onto the steering wheel and dashboard, particularly during rain or after a car wash. This issue began on [XXX] and I saw couple of times under these conditions, posing a potential safety hazard due to driver distraction and possible damage to electrical components. I have taken the vehicle to Hillside Toyota on 05/05/25 and 07/21/25 where they inspected the vehicle but could not identify the source of the leak” or “attempted a repair, but the issue persists. This issue is concerning, as it affects the safety and functionality of my vehicle, which has only 1184 miles INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle suddenly gave several warnings of “check engine visit your dealer”, “Hybrid system malfunction”, “AWD system malfunction 2WD activated” and “System malfunction visit your dealer.” The vehicle was bought new 4 weeks prior. Took it to the dealership and the technician said there was coolant all over the engine compartment and there was a leak somewhere. After inspection he told us that a small rock hit the radiator and caused damage. Told to replace the radiator and flush the system and it was not covered under warranty. After research was done, it was found there was a forum with hundreds of not thousands of people with the same issue. This has been an issue with the new OEM front grill not protecting the radiator and leaving it susceptible to be damaged easily. Toyota Corporate was called and said they were aware of the issue for some time. Even the Technician told us this is a common issue with this vehicle. Also if you place something inside the grill to protect the radiator, it will void the warranty.

The vehicle was in PARK and the IGN was in the ON/RUN position and the air conditioning was on. There was no one in the driver's seat but there was an occupant sitting buckled in the front passenger seat. The passenger heard a sound (possibly the ICE turning on) and he felt the vehicle move forward about five inches. He became worried about his safety and pressed the IGN button in order to turn the vehicle off. It could have pushed itself into other cars in the parking lot or pedestrians. A report was made to the local police department on the same day. This occurred in a retail parking lot. Video footage cannot be obtained as a police officer or insurance company must request it. I have not seen a check engine light nor any message prompts and it has not been inspected by a dealership.

Missing the wire connector for the puddle lamp installation? although not a safety issue, would like to bring this to attention; wire connectors (and wires) missing on both driver and passenger doors? Not sure if this was a factory oversight, or an error in original wiring diagram of Toyota? If so, there could be other wires missing in the vehicle as well. Hopefully Toyota will look into this and propose a fix for their customers. Thank you

I am submitting this complaint regarding a serious safety hazard and design flaw with the 2025 Toyota Grand Highlander Hybrid. While driving on a two-lane highway, our vehicle suddenly lost power and warning lights appeared on the dashboard. We were forced to exit the highway immediately (we were less than 0.5 miles to an exit). Shortly after pulling onto the off-ramp, the vehicle entered limp mode, significantly limiting its ability to function - all assist systems deactivated amd the car has a significant decrease in power. We were able to drive approximately half a mile to a nearby gas station, where we called for a tow. This situation left us vulnerable on a busy roadway, placing both us and other drivers at risk. The Toyota dealership diagnosed the issue as damage to the hybrid inverter radiator, allegedly caused by a rock or piece of debris entering through the front grille. We were told this was not covered under warranty, and to make matters worse, the necessary part is currently on backorder for three weeks to three months—leaving the vehicle undriveable. A significant concern is the design of the front grille, which has large, open gaps that allow ordinary road debris to enter the engine compartment. This leaves critical components like the hybrid inverter radiator exposed and vulnerable, even under standard driving conditions. After researching, I discovered numerous similar reports from other Toyota hybrid owners—including those with Grand Highlanders, Highlander Hybrids, RAV4 Hybrids, and Prius models—who have experienced the exact same issue. In nearly every case, drivers were told it was due to external damage and denied warranty coverage. This presents a clear and growing safety issue: 1. Sudden power loss on a highway or arterial road increases the risk of collision. 2. A critical hybrid system component is inadequately

Front Windshield cracked out of nowhere with no trauma, , now needs replacement due to crack expanding. I discovered it in the morning when my car was parked and not driving.

When going over rough or uneven roads, the car produces a strong low-frequency resonance, like a bass-heavy "boom". This causes a very uncomfortable feeling of pressure changing in my ears, gives me a headache and ear pain whenever I drive in local roads, which is the majority of driving in my area. This causes me to need to pull over and stop the car frequently to readjust my hearing. I've found many reports from others of the same issue but Toyota have not acknowledged it or found a solution.

Hood on 2025 Toyota Grand Highlander vibrates/flutters due to poorly designed aluminum construction. Very distracting and causes drivers to take eyes off the road. Toyota has issued T-SB-0111-24 for the 2024 Grand Highlander for this specific issue but my dealership told me that it doesn't apply to the 2025 but the hood part number is the same for both years. The constant vibration could eventually "work harden" the thin metal and ultimatlly allow the hood to break off the vehicle. Check out the old Jimmy Stewart movie when the constant vibration made the tail break off the airplane.

The contact owns a 2025 Toyota Grand Highlander. The contact stated while reversing, the back over prevention system failed to function as intended. The contact stated that the image was visible; however, there was no tone alert. Additionally, there was a message indicating that the Adaptive Cruise Control was unavailable and to see the dealer. The vehicle was taken to the dealer; however, the failure was not duplicated. The contact stated that the automatic braking system had independently activated. The contact stated that the failure had occurred several times. The contact stated that the instrument cluster was replaced two weeks prior to the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 10,000.

The Panoramic Roof Glass shattered on its own while driving on the freeway, there were no overpasses, no trees, no semi-trucks, no other vehicle in front of me while i was driving. The shattered glass pieces fell on my children in the back seats luckily there were no injuries as we closed the screen immediately.

The 2024 and 2025 Toyota Grand Highlander has excessive hood shaking and vibration at the rear of the vehicle. It is directly under the projection area of the windshield and directs your attention to the movement. At highway speeds the shaking is excessive. Toyota has not been able to find a repair for this issue.

Fuel fill-ups averaging 13-14 gallons when vehicle trip computer alerts 0 miles remaining distance to empty. Fuel tank capacity published as 17.8 gallons. Total vehicle range understated, requiring more frequent stops at gas stations to fill. Not a direct safety concern, but a significant nuisance and dealer has stated this is normal and there is no fix for this issue. EPA estimated MPG 26-27, should equate to approximately 460+ miles/tank. Instead experiencing approximately 350-365 miles per full tank of fuel.

The entire life of the car from initial purchase the fuel gauge is incorrect. The car has a 17 gallon gas tank and the fuel gauge is calibrated to around 13 gallons. The car thinks it is out of gas around 13 gallons when there is actually 4 more gallons left.
