2024 Toyota Grand Highlander Electrical System Problems

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.

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.

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.

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)

Over 1.5 years of owning my new 2024 grand Highlander platinum hybrid pro max I have had multiple incidents (6 documented now with toyota) where after coming to a complete stop I go to accelerate and the car shutters,sputters,lunges, and even looses power or goes into “limp mode”. I have been almost hit several times now by oncoming traffic because my grand Highlander completely loses power. It will not accelerate. After 5 seconds I typically hear loud groaning noises followed by two loud bangs and two violent lurches forward before my car finally regains power. No warning lights popped up on my dash any of the times my car has lost power. My dealership keeps telling me “no problem found” and that I am the only one with this issue. This is false. There are many complaints online and finally after I did not give up the dealership pulled a comprehensive RoB scan/report on my car and found multiple transmission failure codes on the transmission system/TCM. One “lack of acceleration code” was even dated two weeks before I bought my brand new grand Highlander with toyota. I received my grand Highlander with 6 miles on it. I was the first owner. My PDI “pre-delivery inspection date was one week after this transmission failure code”. When I presented this to toyota reps who finally met with me at the dealership they had nothing to say. Toyota knows about this problem and they do not know how to fix it. It is a serious safety issue and I refuse to allow someone to get hurt because Toyota will not be honest and relay this known issue. After the dealership and toyota reps told me I was the only one with this issue toyota officially released a service bulletin in March 2025 for a TCM flash reset/update to address sluggish acceleration, loss of power, and limp mode with the transmissions TCM when the hybrid systems battery is at 33% or less. My dealership installed the TCM update about 1.5 months ago and unfortunately my car has had two more instances since with loss of power.

The vehicle airbag is not fixed yet it is almost on year now. Either had to fix or issue new car. even the price come down now lost money due to bad name. when driving suddenly the safety fails and shows error the blind spot. And there is another recall also electrical one they ask us to come fix. How come a car be safe if airbags do not deploy you have to force them fix it please one year is too much it is safety concern.

fuel guage does not accurately indicate the amount of fuel in the tank. when guage showing completely empty the car takes about 12 gallons to fill, tank capacity shown in manual is 17.2 gallons.

Sometimes the radio lose volume all the way. You could turn the volume all the way up , change stations, FM, Sirius and nothing happens. The only way that this issue goes away and you can go back and start listening is to turn off completely the vehicle, leave if off, for a few secs, then power on . turn on the vehicle. This is very annoying since if you are driving for a long period of time, you cannot turn off the vehicle to do this trick. I hope this 3.0 Toyota Multimedia works better and more reliable.

Toyota provides the ability to use a phone for a key. Only one key was provided due to chip shortages. My phone has been registered as a key. I left my home with only my phone. Upon coming out of the store my phone would not open the door after trying numerous fixes including calling Toyota. My wife unlocked the car remotely via satellite. Trying for 20 minutes with Toyota we could not get the vehicle to recognize my phone. My wife had to drive the only set of keys to my location. The vehicle still wouldn't start until I unlocked the vehicle with the FOB. Had this issue occured in a remote area without cell service I would have been locked out of my vehicle with no way to call for help.
