2024 Toyota Grand Highlander other reported problems

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.

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.

What component or system failed or malfunctioned, and is it available for inspection upon request? I was driving when I heard a loud boom, it almost sounded like a gunshot. Not noticing anything I continued driving. After a short distance I started hearing wind whistling. It was at this point I pulled over and saw my sunroof had shattered and there was a big hole. How was your safety or the safety of others put at risk? If I had not have the shade closed glass would have fallen into the car. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, I brought the car to the Toyota dealership. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? I did call my insurance company but I am not sure if they actually inspected the damage. They have been dealing directly with the Toyota dealership service department. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, that's why I continued to drive until I heard the wind whistling

My 2024 Used Toyota Grand Highlander Hybrid Platinum Max was at a slight decline stopped at a stop sign in Echo mode. The whole car began to violently shake and lurching forward. No one was in front of me and my foot was on the brake or I probably would have run into a car in front of me. The dashboard then flashed a warning about the hybrid system overheating. The only way to stop it was to turn off the engine, then turn it back on. The car then began driving normally. I have also had an issue with hesitation felt while accelerating 0-40 mph with study throttle. Upon researching both issues, they should be resolved with TSB calibrations to my car of T-SB-0028-25 and T-SB-0017-24. This is not an error that would come up when doing a diagnostic check on my car's computer per research I have done. I took my car to get the updates at Toyota of Redlands, CA, and they refused to do them unless they could recreate them themselves. I called Toyota to report this, and they said that each Toyota dealership/service is privately owned at their own discretion. I was basically told to return if I experience it again. I do not want to experience this again and they wouldn't take my word on it anyways. I feel like next time I could injure myself or someone else if this glitch happened again. I therefore would like to implore to make this a mandatory preventative TSB calibration for cars that have had this reported/models/year which mine has. This goes for any TSB calibrations should be done preventatively, but especially ones that can cause a potential accident like T-SB-0028-25 and T-SB-0017-24. Here is information on why this would not show up on a diagnostic test: Your Toyota didn't generate an error code because the shudder is a software calibration issue rather than a component failure. The onboard computer (ECU) only triggers a check engine light or throws a Diagnostic Trouble Code (DTC) when sensors detect a hard mechanical or electrical failure.

There is an ongoing problem with Android connectivity. I have brought this to the dealer’s attention multiple times, but they continue to claim that my phone is not compatible. However, this same phone connects flawlessly and consistently in my other vehicles, so compatibility does not appear to be the issue.

This is regarding recalls for my 2024 Toyota Grand Highlander Hybrid Platinum Max. The vehicle has been in the possession of Koons Tysons Toyota since December 23, 2025 (80 days as of 3/11/26), for repair of Safety Recall #25TA13 and #25TB13 NHTSA 25V744) involving the Panoramic View Monitor System/Parking Assist ECU. The dealership has explicitly informed me that the vehicle is unsafe to operate and have therefore kept it. Toyota and its authorized dealer have made three (3) repair attempts to correct this safety defect. Two separate replacement components were ordered and installed without resolving the issue. A third required component is currently on backorder with no definitive ETA or repair completion date, as the date keeps getting pushed. We are not being updated and are not receiving information from the dealership and Corporate about the details about the problem and nature of the delay. Toyota has obligations under federal recall law administered by the National Highway Traffic Safety Administration (NHTSA) to remedy safety defects within a reasonable time and at no charge to the consumer. An indefinite inability to complete a safety recall repair due to parts unavailability raises serious concerns under those obligations. Furthermore, a previous recall #25TA08 (NHTSA 25V595) which was supposedly completed on October 14, 2025 by the same dealership is showing as INCOMPLETE in the vehicle record with NHTSA.

UNKNOWN, vehicle dash warnings advising front sensors were not working causing error messages. The vehicle was taken to the dealership for a recall and they advised the Right front Ultra Sonic Sensor also needed to be replaced. They alleged this was potentially caused by an unknown impact such as small rocks or bugs. The faulty sensor causes error messages on the dash and needed to be replaced. They would not cover this under warranty which is a repair cost of $823.81. The only other band aid was to turn of the other sensors to get rid of the dash notifications, not allowing the other sensors to work as designed to monitor items or people in front that may not be seen by the driver. This turns off some of the vehicle's safety features. Toyota was directly notified of this incident but refused to cover the issue under warranty and expects consumers to pay for a new sensor and programing for a part that is faulty or not durable enough to perform under normal driving conditions. I am making this notification to NHTSA so there is a record of the issue with the durability of the Toyota Ultra Sonic Sensor or failing under normal driving conditions in case there are other complaints about the same issue.

Vehicle Safety Complaint — 2024 Toyota Grand Highlander My 2024 Toyota Grand Highlander has experienced multiple serious defects, including two official recalls: • 25TA08 — instrument cluster failure • 24TA09 — airbag defect This week, the instrument display failed completely, making it impossible to view speed or system warnings. I’ve been unable to work since then, causing financial hardship for my family. Earlier, I also had to replace the entire drive shaft at my own expense (~$2,500), which is highly unusual for a new vehicle. These repeated issues raise serious concerns about safety and reliability. I’ve submitted a formal complaint to Toyota Brand Engagement Center, and it has been acknowledged and assigned to a Case Manager. The dealer is still searching for a suitable loaner vehicle that meets my work requirements. Given the severity and recurrence of these defects, I request that NHTSA investigate this pattern and consider whether the vehicle qualifies for buyback or replacement under applicable consumer protection standards. • VIN: [XXX] • Mileage: 96150 miles INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Description of Issue: We have experienced multiple episodes of violent shaking in our 2024 Toyota Grand Highlander while stopped at red lights or in intersections. Both my wife and I have had this happen independently, around two to three times each. Most incidents occurred while our young children were in the vehicle. The most recent incident occurred today, when my wife experienced it twice in a row while stopped at an intersection. Our children were not in the vehicle during today’s event. Component or system involved: UNKNOWN at this time. We suspect a major mechanical or drivetrain-related failure. The entire vehicle shakes violently and feels unstable. We are willing to make the vehicle available for inspection upon request. Safety risk: The severity of the shaking is extreme and it feels as though the car may explode or fall apart. We have had to put the car in park, shut it off immediately, and in some cases, exit the vehicle in the middle of intersections or while stopped at a red light. This places everyone in the vehicle at serious risk, especially our children, and could result in a crash or secondary accident due to the abrupt stop and unexpected behavior in active traffic. Has the problem been reproduced or confirmed by a dealer or service center? The issue has not yet been reproduced by the dealership. We brought the vehicle to Toyota of Escondido after a previous incident. They inspected it but stated they could not find anything wrong. Has the vehicle or component been inspected by others? The vehicle was only inspected by the dealership (Toyota of Escondido). It has not been reviewed by any other parties such as law enforcement or insurance representatives. Warning lamps, messages, or other symptoms prior to the issue: There were no warning lights, error messages, or abnormal behavior prior to the onset of the violent shaking. The issue occurred suddenly each time, without warning.

Sometimes,about 50/50 now, when I stop at a light or a stop sign then try to go, my car refuses to go. Pressing the gas won’t make it go. I just sit there idling or worse, in the middle of oncoming traffic. The lights still work, everything else seems to work. This does this with or without the ac in. It almost jerks you around, but won’t go. This has happened multiple times now.

Ever since I got my car, sometimes it smells like gas on the right side of the vehicle. By driver side and right passenger side in the back. I assumed it was because I topped my gas off, but even when I stopped doing that, it still has a strong gas smell when the car is running and after turning it off. Not ever day, but ever so often.

I was informed by my Toyota dealership and received a written letter from Toyota dated March 25, 2025, that the curtain airbag recall on my 2024 Toyota Grand Highlander had been completed. However, during a scheduled maintenance visit in June 2025, I was told the airbag recall had never actually been performed and was still open. The recall was only completed at that time. I unknowingly drove the vehicle — often with my infant child — for several months, believing the airbag system was safe, based on incorrect information from Toyota. This represents a serious safety concern and a breakdown in Toyota’s recall management. The issue has now been fixed, but I am reporting this because I was misled into driving an unsafe vehicle, putting my family at risk. Toyota’s failure to properly close and track recall repairs should be investigated.

The vehicle’s design leaves the condenser completely exposed, with no protective barrier in place. As a result, even a small rock can easily pass through the front grille and cause significant damage. That’s exactly what I’m currently experiencing, and unfortunately, Toyota has refused to cover the repair costs. What’s more concerning is that I’m far from the only one — many other owners are dealing with the exact same issue. It’s clear that Toyota needs to take responsibility and implement a proper solution to protect the condenser moving forward.

UNKNOWN OR OTHER

Shortly after starting my vehicle and driving out of my neighborhood, there are a series of stop signs. The roadway is at a slight incline. When attempting to press the gas pedal after stopping at the first stop sign, my vehicle hesitates or does not accelerate. This lasts anywhere from 1-5 seconds. This occasionally also occurs again at the second stop sign a few hundred yards later as well. The best I can describe this is as an unresponsive gas pedal or limp mode. I cannot stress how incredibly dangerous this issue is. Someone is going to get seriously injured or killed if this isn’t acknowledged by Toyota or NHTSA. All it takes is for this to occur when someone is making a right hand turn into a roadway. I am fully aware that this is not an isolated incident with my vehicle and other vehicle owners of Toyota Hybrid Max Platinums report this same issue.

I was traveling on HWY 70 in Colorado outside Frisco at 65 mph temp about 35 degrees on 4/4/2025 when I heard a loud explosion. I pulled over and identified that the panoramic sunroof glass had exploded outward. There was no way a projectile could have hit the glass as a cargo carrier was on the roof rack completely covering the glass. The glass had an upward projection as well. I have included photos. The dealer refuses to take responsibility for the poor construction of the sunroof glass.

Intermittently, my vehicle will hesitate to accelerate or will move only marginally (disproportionately to the depressing of the gas pedal) from a complete stop. When it occurs, it often does so for a number of seconds. This has been incredibly dangerous given I live off a busy street and I cannot trust that when I press the gas pedal to accelerate to turn onto the street, that my vehicle will be caught in oncoming traffic and hit.

CV joint/ axle malfunction. Vehicle is at 15,000 miles and both front cv joints and axles needed to be replaced. Only highway driving done.

I saw that a recall was posted on my Toyota app. June 28, 2024, I called for recall repair, regular service and second key. I was advised that the recall did not have a remedy, but I needed to bring it in for regular service. Service was scheduled for July 13, 2024. At that appointment, I followed up on the recall. They advised that the recall is open but Toyota did not have a remedy, so just keep monitoring it. I called on November 5th , to check on the recall and a service campaign alert that was issued on my Toyota Application. They said for that I needed to bring it in during the week, we scheduled the recall repair for 11/12/2024. When I picked up my vehicle, I was advised that they had to order the part for the recall. They performed regular maintenance, etc. however, the recall is still open and has not been repaired.

I was heading home with my 6 year old son when all of a sudden there was a loud boom. Initially I thought there was an explosion or gun shot but then realized the panoramic moonroof had shattered and I continued hearing shattering. I pulled over the car to make sure I could creat some sort of safety for my son. I took some pictures. There was nothing that touched the glass. It just shattered. This was terrifying.

Sometimes when I switch gears- for example, go from Park to reverse- the vehicle won't move. I can press on the gas and nothing happens. If I wait a second, I can press the gas again and it will go. Or, I can put it back into park and then reverse again, and the car will move. It's unsettling when it happens because there is no rhyme or reason, I switch to reverse or drive and I press the gas and I can't move. It feels dangerous. I asked the dealer and he didn't have an answer. Sometimes it happens every week or a couple days in a row or I can go a couple weeks and it doesn't happen.Ive had the vehicle for over a year- and it started from the beginning and continues to this day.
