2024 Toyota Grand Highlander complaints

On [XXX], while driving my 2024 Toyota Grand Highlander at approximately 45-50 mph on a gusty, high-wind day, the rear panoramic moonroof/sunroof panel blew out and shattered completely without warning. The failure occurred as I rolled up the vehicle windows during the wind gust. Rapid window closure created a sudden spike in cabin air pressure — a documented pressure differential mechanism — that forced the moonroof glass outward until it shattered. There was no external impact of any kind. The glass, which is not laminated safety glass, scattered throughout the interior with occupants present. Component is available for inspection. This failure is consistent with NHTSA Investigation PE13-035 (Kia Sorento panoramic sunroof spontaneous breakage), in which ODI found glass shattering while in motion to be a safety hazard warranting engineering analysis. The same pressure-based failure mechanism applies here. This is a documented pattern on this specific model. Lemberg Law [XXX] ) analysis of NHTSA complaint data confirms spontaneous sunroof shattering among the top defects on both 2024 and 2025 Grand Highlanders, with Toyota denying warranty claims by alleging "outside influence" — disputed by owners and attorneys alike. No recall currently exists for this component. The rear seat directly below this glass is a primary location for child safety seats. Non-laminated glass shattering over rear occupants — including infants — represents an acute and unacceptable injury risk. I req

3rd row seats do not want to lock into position, there is also broken plastic pieces from the locking mechanism area. Seats do not want to engage or disengage when trying to lay them flat. This had been a reported problem on other highlanders. This has been an issue since we purchased the vehicle in 2024. This is a safety issue because I fear they would fail in a crash.

It was noted that the drivers door weather strip deteriorated even though the car is less than 3 years old/ 47,000 miles. The dealer and the Toyota customer care said it is likely related to external factors and not covered under warranty. I keep the car in a garage. We have had other cars that are well over 10 years old but do/did not have this problem. This can potentially lead to damage of other components. I see on the internet that other owners of this car have encountered this same issue . There have been 3 safety recalls on this model, related to air bag, instrument panel and rear view camera. These have been fixed. There have been at least 5 Toyota technical service bulletins ( TSBs) published on this model. These were fixed after I brought it up with the dealer/ manufacturer. I was not contacted by the manufacturer proactively. TSB 0017-24 : hesitation felt while accelerating from stop. A software update was performed. TSB 0060-25 : Fuel level logic enhancement. A software update was made. TSB 0028-25 : Shudder sensation at stop. A software update was performed. ​T-SB-0082-24: CV axle issue: it was fixed T-SB-0111-24: vibrating hood.I notice the issue but did not fix it since the fix involves placing a foam under the hood, which may not fix the underlying issue and might cause other issues. I believe these issues are related to the manufacturing oversight and especially more frequent because it is a first year model .

The rotors started warping around 8K miles

While traveling at highway speed on I-75 northbound, the vehicle experienced a complete and total loss of electrical power. and propulsion. The following conditions were present simultaneously: - Complete loss of propulsion - Inability to shift transmission to neutral — vehicle could not be moved out of the active traffic lane - Complete loss of hazard lights — no ability to warn approaching traffic - Vehicle remained stranded in active highway traffic for approximately 15 minutes - Electrical power spontaneously restored after approximately 15 minutes - Vehicle was then driven off the interstate under its own power That was a life-threatening event. My wife and I could have been struck from behind by highway traffic with no warning lights, no ability to move the vehicle, and no way to signal distress. DEALER VISIT 1 — SATURDAY, APRIL 26, 2026 Dealer: Sarasota Toyota, Sarasota, Florida Complaint presented: Complete electrical shutdown on I-75 the previous day as described above Action taken by dealer: Performed recall repair for black screen issue Outcome: Vehicle returned to customer same day Post-repair symptom: Low voltage warning appeared on drive home from Sarasota Toyota Saturday afternoon Note: Dealer did not perform full electrical diagnostic. Dealer did not flag battery failure. Dealer did not retain vehicle for further investigation despite being informed of complete highway electrical shutdown the previous day. DEALER VISIT 2 — MONDAY, APRIL 28, 2026 Dealer: Germai

The vehicle hesitates and does not accelerate immediately from a complete stop. This occurs more frequently when the car is on a slight incline. The delay in acceleration creates a safety concern, especially when attempting to merge into traffic or pull out onto a roadway. I have reported this issue to the dealership multiple times, but they have not taken action because they have been unable to reproduce the problem.

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.

When making turns under acceleration at various speeds, there is a noticeable clunk noise from the front section of the vehicle. The sound can be described as a coil that is being compressed/decompressed and creates the noise. The noise is heard when loading and unloading the steering wheel during a turn.

Front brakes were worn prematurely and rotors had to be resurfaced multiple times under warranty and once more after warranty. Premature wear would cause shaking in the steering wheel when medium to heavy braking force was applied.

My car read system malfunction and come to find out there was corrosion with the wires in the internal circuit of the driver side mirror that prevents it from warning you of blind spots and pre-collision.

The contact owns a 2024 Toyota Grand Highlander. The contact stated that the display was not functioning properly, and the screen was blank while operating. The contact stated that after the "Get Started" prompt was displayed and selected, the screen would go blank. Additionally, the back over prevention camera was inoperable. The vehicle was taken to the dealer; however, the vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 22,679.

It didn't work it didn't brake or didn't have an alert in which caused an accident

I was driving toward the perimeter of my neighborhood, approaching an arterial cross street. When I braked the pedal went straight to the floor. The breaks didn’t work despite pumping them multiple times. I also heard the engine revving. To avoid the intersection and busy street I steered into a yard, hit a retaining wall and a tree, rolled and hit a metal city street sign. All airbags deployed. I was taken to the hospital by ambulance. The car was totaled and is on a temporary hold at a salvage yard.

The incidents most often occur when I try to accelerate after vehicle is stopped at an intersection. 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. The RPMs get up 4500 while the car is going 25-40 mph and remain there for a few seconds up to ~20 seconds. I am fearful of getting t-boned when my car hesitates while turning at an intersection, going through an intersection or pulling out from a parking lot. I have been stuck in several intersections when traffic was coming toward me, but thankfully those cars were able to avoid hitting me. I have reported the problem every time I take the car to the dealer for a service. The problem has been happening since I purchased the car in November 2024 and occurs randomly--sometimes every couple of months, sometimes days in a row. The dealer can't reproduce it, but they were able to pull a code from the transmission and found it had an acceleration error. They updated the software from a TSB, but that didn't help.

The transmission needs to be replaced per the dealership. I was told this on 3/7/26 with mileage of 69K. The transmission has been reported as defective to Toyota since 2016-2017 with multiple lawsuits that have been filed. According to the lawsuits found online, Toyota knowingly used the defective UA80 transmissions and failed to inform consumers when purchasing the vehicles or inform consumers the need to replace prior to the 60k warranty expiration. The 2024 Grand Highlander has been listed as one of the affected vehicles and the transmission can fail at any time which is a safety risk.

Reported issues of lag in acceleration and harsh shifting into reverse, the vehicle has been brought to the dealership multiple times stemming from shortly after previous, there are no warnings lights on. I requested the dealership provide in writing if the deemed the vehicle safe for operation. They would not do so. I requested a loaner while my vehicle is being reviewed for repurchase and was denied. When my repurchase claim was denied, I requested a reconsideration and again a loaner.

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.

On February 25, 2025, I took my car into Freeman Toyota dealership in Santa Rosa for a recall on the airbags (24TA09 SAFETY (NONCOMPLIANCE) RECALL 24TA09(Remedy Notice) - Certain 2024 Model Year GrandHighlander and Grand Highlander HV - Curtain ShieldAirbags May Not Deploy As Intended). In the labor notes, they claimed to have performed the recall - 1. PERFORMED THE 24TA09 AND REPLACED BOTH LEFT AND RIGHT HAND CSA ASSEMBLIES. OP CODE: 24TA09R1.3.1 HRS. However, on June 24, 2025, the Toyota was involved in a collision with a deer. The autobody shop confirmed that the airbag sensors went off, but the airbags did not deploy. A claim was filed with my insurance company, and the airbags have been replaced by the autobody shop. The vehicle did not get back to the dealership.

The contact owns a 2024 Toyota Grand Highlander. The contact stated that after driving into the garage and while pressing the brake pedal, the vehicle suddenly experienced unintended acceleration, lurched forward, and crashed into the husband's workbench. During the incident, the brake pedal was forcefully pressed, but the vehicle did not immediately stop. No injuries were reported. The husband's workbench was destroyed. The vehicle was later driven to the local dealer, who was unable to determine the cause of the failure. The manufacturer was notified of the incident, and an investigator was sent to examine the vehicle. The investigator reported that no trouble was found with the vehicle, and the crash was due to driver error. The contact insisted that no driver error had occurred, and the incident occurred while the brake pedal was being forcefully pressed. The failure mileage was 14,000.

My car suddenly shook violently while at complete stop at a stop light. Also, the brake feels weird at times when slowing down.

I am submitting this complaint regarding a catalytic converter failure on my vehicle and the manufacturer’s refusal to honor the warranty. My vehicle is a Toyota that is approximately two years old and currently has about 31,000 miles. The catalytic converter has failed well before what would normally be expected for this component. When I brought the vehicle to the dealership for repair under warranty, Toyota declined to cover the repair. They stated the failure was due to “contaminated fuel,” but they did not provide any evidence or test results showing that contaminated fuel was present in the vehicle. I have not been provided with documentation, diagnostic data, or fuel analysis supporting this claim. The denial appears to be based on assumption rather than proof. Because catalytic converters are emissions components that are typically expected to last much longer and are often covered by extended emissions warranties, I am concerned this may represent a broader issue affecting consumers. Vehicle details and service documentation can be provided upon request. I am requesting that this matter be reviewed and that the manufacturer be required to provide evidence supporting their claim or honor the warranty repair. Thank you for your time and consideration.

The contact owns a 2024 Toyota Grand Highlander. The contact received notification of NHTSA Campaign Number: 25V595000 (Electrical System), and the vehicle was taken to the dealer on several occasions, but the dealer informed the contact that the part to do the recall repair was not yet available. The contact stated that the instrument panel had failed. Additionally, the contact stated that the vehicle was not driving properly, and the vehicle was shuddering while exceeding 70 MPH. The vehicle was taken to the dealer, where it was diagnosed with an axle leak, and the contact was informed that there was no warning light illuminated for the failure due to the instrument panel failure. The axle leak was repaired; however, the failure persisted. The vehicle was not repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was notified of the failure, and a case was filed; however, no assistance was provided. The failure mileage was approximately 9,000.

I own a 2024 Toyota Grand Highlander Hybrid and am experiencing an intermittent knocking/clicking noise that appears to come from the drivetrain area. The noise occurs most often during low-speed driving and while turning left or right, particularly on the first drive of the day after the vehicle has been sitting overnight, but it has also occurred at other times while driving. The condition is intermittent and does not occur every trip, however it has been heard by multiple drivers. The noise is most noticeable during light acceleration combined with steering input at lower speeds. I have brought the vehicle to the dealership for inspection, but the condition has not yet been duplicated during testing. I am concerned this may indicate a developing drivetrain or axle-related issue that could affect vehicle safety if it worsens while the vehicle is in motion. I am submitting this report so the condition can be documented and evaluated for potential safety concerns affecting this vehicle model.

I had my front axle assemblies replace under T-SB-0082-24 around 20,000 to 25,000 due to rotational clicking noise per bulletin. The tsb uses the old part number which was the defective original part. The axles are failing agin at 50,000 and the dealer and toyota are refusing to fix it as they can’t replicate in shop. There is a new part number that was updated and supposedly fixed the issue but that is not the part that was installed in my car. They stopped the production line and updated the part at one point supposedly there was not enough grease in the cv joint boots causing premature wear. The old part number is still listed in the tsb even though it is superceded, tsb should be update or recall issued for all affected models to get the new updated part. Old part number 43420-0E340 new part 43420-0E341. Other side old part 43410-0E520 new part 43410-0E521. Toyota installed the old obsolete parts on my car in all paperwork for my work history and is refusing to install a working set of axles.

2024 toyota grand highlander had TSB 0082-24 repair done around 20,0000 to 25,000 miles due to rotational clicking noise and vibration when turning under power. Both front axles replaced. Car now has 50,000 miles on it and clicking noise is present every day in cold conditions until it warms up. It is at the dealer for the third time and they are unable to replicate the clicking and vibration and will not replace the part. The symptoms are identical to when the first repair was done. Possibility of cv axle failure in the near future if not replaced. A full recall and redesign is needed at this point if I am experiencing 2 failures within 50,0000 miles.

Clicking noises from front of engine area/tire area whenever steeing wheel turned left or right turned out to be cv axels and replaced feb 2. 2026 -so far will monitor for recurrence - grand highlander forum with numerous such complaints

In the middle where the car chargers are – the one in the center isn’t working but the one to the right is. When doing maps, the visual map disappeared and just showed where to turn – happened about 2-3 time. Today the entire screen went black – no radio, phone, maps, nothing. No way to operate it at all. This is unrelated to the current recall that addresses the speedometer / display right behind the steering wheel.

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.

The contact owns a 2024 Toyota Grand Highlander. The contact received notification of NHTSA Campaign Number: 25V595000 (Electrical System); however, the part to do the recall repair was not yet available. The contact stated that while driving at various speeds, the instrument panel failed to show critical information as intended. No warning light was illuminated. The vehicle was taken to a local dealer, where it was diagnosed and determined that the failure was recall-related; however, the parts were not available for the recall repair. The manufacturer was not made aware of the failure. The failure mileage was approximately 90,000.

When I turn to the left or right I hear a clicking/popping noise. Took it to the dealer and they said it was the CV axle. So they replaced the driver side. After the repair, it would make the same sound from time to time so I took it back in to the dealer(Northside Toyota in San Antonio, TX) they couldn't recreate the sound and notated my account. This was all when the car had less than 30k miles. The grand highlander now has 47k miles and it is making the noises alot more. Im on a grand highlander forum and a lot of other owners are having the same issues. Some are already on their 3rd set of cv axles.

The defroster on the vehicle does not work properly. When starting the car and the window is frosting, the drivers side of the front window defrosts normally but the right side does not defrost properly and it lags by 15-20 minutes. You cannot operate the vehicle safely with your entire passenger side frosted over. I reported this to Toyota as well as dealer and they are advising that it is working normally. I have pictures that show that the passenger side does not defrost properly, it was reproduced by the dealer, and Toyota's thermal imaging scan confirms lack of heat on the far side. However, Toyota is standing by that it is working as designed despite their testing showing it isn't working properly.

My vehicle has been out of service since October 7, 2025 due to a complete failure of the instrument cluster (combination meter). This issue is related to SAFETY RECALL 25TA08. The instrument panel is fully non-functional, making the vehicle unsafe and inoperable. The vehicle has been at Toyota dealership for approximately three months, with no repair completed and no clear timeline provided. The dealership stated they are awaiting instructions from Toyota Corporate and cannot proceed independently.

I have taken my vehicle to Wilde Toyota (2 time) for the same issue . The car either moves/slids to the left or right. They adjusted the wheel alignment in November and now again I am having the same issue. Took the car again to Wilde Toyota and they are asking me for 185 USD for the wheel alignment. I told them this looks like a drive train or suspension issue but there were hesitant to check it.

Third row seating bottom (back side) has loose flap material end the bottom, when closing and opening the seat it’s can get stuck. It’s also possible the seat can probably even collapse while in use or in driving. The dealer tried to help but there doesn’t seem to be any solution for this from Toyota. This seems to be model wide issue as I was told by dealer. They had another one with same issue. The bottom back of the seat is literally loose flap material. The only solution was they replaced the cargo tray which was actually slightly BENT at front possibly due to seat struggling to close and opening due to faulty design. THIS IS A FAULTY DESIGN! ITS LITERALLY A LOSSE FLAP PLASTIC MATERIAL ON A SEAT BACK. The dealer told me to be careful when handling these seats bc the material can break easily and there isn’t solution from Toyota on this unless there is recall or safety notice.

I am filing a complaint regarding a safety recall on my Toyota vehicle. Toyota issued the recall notice on September 11, 2025, but as of today there is still no available remedy. Due to this recall, my vehicle has been deemed unsafe and undriveable and has been out of service since October 8, 2025. While a rental vehicle has been provided, I have been without my own car for several months with no clear timeline or resolution. I am concerned about the extended delay in providing a recall remedy for a safety-related defect and the lack of transparency regarding next steps. I am requesting that NHTSA review Toyota’s handling of this recall, including the prolonged lack of a remedy and the impact on vehicle owners. I believe this delay is unreasonable and warrants further oversight.

My Toyota Grand Highlander develops severe interior window fogging and condensation, affecting the windshield, front side windows, and occasionally rear windows. This occurs during normal driving, especially in cool or humid conditions. The fogging appears rapidly, and the HVAC/defrost system often fails to clear the windows effectively, even when set to full defrost with outside air intake. Interior moisture buildup is excessive compared to other vehicles I’ve owned, and the issue repeats regularly. This creates a significant visibility hazard, forcing me to adjust climate controls constantly while driving or pull over to clear the glass manually.

My car is a 2024 Grand Highlander I bought in May of last year. It currently has 20,000 miles on it. A few weeks ago I started hearing a knocking sound when I turned left or right. I looked at some Toyota forums and found that other people were having this issue and had to have both front axles replaced. I took my car to Toyota and sure enough, they said the parts they used to assemble the car were not machined properly and they replaced both of my front axles. Having said that, I have 2 issues. One, why hasn't a recall been issued on this. It seems as though quite a bit of people have had this problem and this is a big safety issue. There have been 2 other recalls, one about the screen going blank and airbags, but to me, axle is a much bigger safety issue, so why no recall on this? Also, the technician recommends an alignment after chaning the axles which I am expected to pay $150 for but this should be included since my axles should not need changing at 20,000 miles. They consider alignment normal wear and tear and not under warranty which I would normally agree with but I only need an aligmnent because they changed my axles.

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 car was in motion, creating a serious safety hazard. The vehicle was properly maintained, and no prior warning lights or issues were noted before the incident. I have done vehicle inspections/ service this month, and they told everything is perfect. This poses a severe risk to driver and passenger safety, and I am reporting it for investigation. Whole car got burned out within 5-10 mins only

The contact owns a 2024 Toyota Grand Highlander. The contact stated that upon starting the vehicle and reversing, there was an abnormal banging sound coming from the vehicle. While attempting to reverse, the vehicle failed to move, but the vehicle was restarted and operated as designed. While driving, there was an abnormally loud clanking sound coming from the vehicle with the “WRENCH SYMBOL” displayed. There were other unknown warning lights illuminated. The vehicle was taken to the local dealer, who was unable to duplicate the failure. The vehicle was not diagnosed or repaired. The contact stated that the vehicle would be taken back to the local dealer for additional diagnostic testing. The manufacturer was not contacted. The failure mileage was approximately 18,000.

All lights and warning system alerts suddenly came on. Hybrid System Malfunction. Once towed to dealership; stone came through large gap in front grill and put a hole in internal radiator. Not covered under warranty. Design flaw appears to be a problem in front grill.

When accelerating from a complete stop, the vehicle intermittently fails to respond when pressing the gas pedal. It feels similar to when a bicycle chain slips—you press the pedal, but the vehicle doesn’t move forward—then suddenly it catches, causing a noticeable lurch. The duration of this lag varies, and it has been increasing over time. Most recently, the hesitation lasted long enough that I was nearly involved in a collision. I pulled out from a stop sign to make a right-hand turn, but the vehicle failed to accelerate as expected. The car behind me nearly rear-ended me due to my sudden lack of movement in the lane. No warning lights, error messages, or other indicators appear before or during the event. I have been reporting this issue to my dealership for over a year during regular service appointments. The dealership has been unable to reproduce the problem and has attempted a software update, which did not resolve it. The malfunction has not been inspected by the manufacturer, police, or insurance representatives. The issue has occurred multiple times, including but not limited to the following dates: -March 12, 2025 -March 24, 2025 -July 21, 2025 -September 18, 2025 -October 1, 2025 These dates reflect times when I documented the issue via text messages to my husband; it has also occurred on many additional occasions not recorded above. Online owner forums and NHTSA complaints indicate that other Toyota Grand Highlander owners are experiencing the same issue, suggest

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)

My car accelerated very fast as I was attempting to pull into a parking spot. At first attempt brake did not work. Was able to avoid an accident. No sensors went off. Best described as an out of control amusement ride.

Toyota T-SB-0082-24 / Rotational Clicking Noise From Front Drive Shaft Assembly ( CV JOINT) CV joint defect poses an unreasonable risk to safety, especially if it fails while you are driving. An unreasonable risk is one where the potential for harm is much greater than the potential benefit of taking the risk. Driving with a compromised CV joint fits this definition because it can lead to a complete loss of vehicle control, which can result in a serious accident.

The contact owns a 2024 Toyota Grand Highlander. The contact stated that there was a small crack on the windshield on the driver's side at the top where the windshield meets the frame. The contact stated that the crack had started to expand. The contact recently noticed another crack in the center of the windshield, starting at the bottom. The contact stated that both cracks were approximately 5 inches long and expanding. The contact had not struck a rock or road debris for the windshield to crack. The contact had taken the vehicle to a dealer to be diagnosed and was advised by the dealer that the cracks were the result of small stones being kicked up by other vehicles. The vehicle was not repaired. Additionally, the contact had been experiencing failures of the infotainment screen going black, and the side-view mirror Blind Spot warning lights not functioning as designed. The vehicle had been taken to the same dealer several times, and the dealer resolved the issue. The contact stated that the infotainment screen failure had reoccurred. The manufacturer was not informed of the failure. The failure mileage was approximately 40,000.

Description of Issue: I have experienced repeated incidents where the accelerator pedal becomes unresponsive (“dead pedal”) after coming to a stop. When pressing the pedal to accelerate, the vehicle does not respond at all for several seconds. Then, without warning, it suddenly surges forward with excessive acceleration once the power engages. This problem happens intermittently throughout a drive each day, often enough to be concerning. It occurs after being stopped at an intersection or in traffic. No warning lights or error messages appear before or during the issue. The delay followed by a sudden surge is dangerous, as I expect the car to move when I press the pedal, but it hesitates instead. When the vehicle finally responds, it accelerates quickly, which could cause me to lose control or collide with another vehicle. Safety Concern: This malfunction creates a significant safety risk. It puts myself, passengers, and other drivers in danger when the vehicle fails to accelerate as expected in high-risk scenarios such as crossing intersections, merging into traffic, or making left turns. The hesitation can leave the vehicle exposed in traffic, and the sudden lurch forward can cause unintended movement or rear-end collisions. Status: The problem has occurred multiple times under similar conditions and is ongoing. It has not yet been inspected or confirmed by a dealer or service center, but I have an apt Aug 24th. However, the malfunction is real, reproducible, and presents a

“Apple CarPlay Escape” is not available through software update for this vehicle although other cars of the same model year and 2025 models have this option to quickly navigate between Apple CarPlay screen and Toyota settings screen. As a result, More swipes/touches are needed on the screen to navigate which is unsafe and distracting while driving
