2024 Toyota Grand Highlander

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)

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.

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.

I have had 2 intermittent issues since I bought this vehicle brand new. 1) Hard, Jerky shifting from 1-2 or 2-3 gear 2) Huge safety issue regarding loss of power and inability to accelerate from a stop even though the car is on and in drive. This has happened to me multiple times and is very intermittent so it is hard to replicate. This has happened when I am attempted to accelerate from a complete stop and the car begins to move but then does not accelerate at all. Almost as if the powertrain shut off even though it was moving under its own power a fraction of a second ago. This has happened to me multiple times with my entire family in the car as we attempted to enter intersections leaving the car powerless with oncoming traffic. Thankfully we were not hit by another car but could have been.
