2024 Toyota Grand Highlander

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.

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, suggesting it may be a widespread defect affecting vehicle safety.

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)

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.
