Note: (1) Although the involved vehicles are within the above production period range, not all vehicles in this range were sold in the U.S.
(2) This issue only affects the vehicles equipped with a certain transmission assembly that uses brake clutch discs of a specific design.
3. Total Number of Vehicles Potentially Involved:
Tundra : 192,351
Tundra Hybrid : 49,763
Sequoia Hybrid : 26,447
Lexus LX600 : 12,102
Total : 280,663
4. Percentage of Vehicles Estimated to Actually Contain the Defect:
Toyota is unable to estimate the percentage of the involved vehicles to actually contain the defect described in Section 5. However, as the NHTSA manufacturer portal requires an integer value be entered, Toyota has entered the value “1” in response to this question in the portal. For the purpose of this report, “1” means “unknown”.
5. Description of Problem:
The transmission assembly in the subject vehicles uses a clutch piston to engage brake clutch discs to plates to transfer power from the engine to the wheels. There is a possibility that, due to an issue in the design of a certain brake clutch disc, when the transmission is shifted to the neutral position and pressure is removed from the clutch piston, the brake clutch discs will not immediately disengage from the plates, allowing some engine power to continue to transfer to the wheels. If this condition occurs when the vehicle is on a flat surface, and if the driver does not apply the service brake or the parking brake, it could allow a vehicle to inadvertently creep forward at a low speed (up to approximately 4 mph), which could increase the risk of a crash.
6. Chronology of Principal Events:
May 2023 – October 2023
In late May, Toyota received a field report alleging that a customer’s vehicle moved forward while the transmission was placed in neutral. An initial inspection was conducted by the dealer, during which the transmission was moved to neutral, the brake pedal was released, and the vehicle was observed to move forward under its own power on a flat surface. The dealer observed a top vehicle speed of 3 mph during this movement in neutral.
Toyota conducted an additional vehicle inspection to further evaluate the customer’s vehicle. Toyota completed a test drive and collected vehicle data (e.g., distance, speed, force, etc.) that
confirmed that the vehicle would begin slowly moving from a stop to approximately 3 mph while in the neutral shift position with no brakes applied. Toyota also confirmed that the service brakes and parking brakes were not impacted by the condition, and if the driver applied either of the brakes, the vehicle would stop moving.
In late June, Toyota began further testing to determine the actual torque being transmitted from the engine to the wheels during this neutral range movement. Simultaneously, Toyota performed testing on additional vehicles in order to quantify the actual rolling resistance torque which was found to be smaller than the torque being transferred from the engine to the wheels. The difference in the two torques was small but determined to be enough for limited movement to occur.
Following determination of the actual torque conditions, Toyota continued with the recovery and evaluation of parts from two vehicles with newly submitted field reports. Once the presence of neutral movement on the vehicles with the recovered parts was confirmed, Toyota performed bench testing on the recovered parts to identify how torque was being transferred from the engine to the wheels. During this bench testing, it was found that certain brake clutch discs were not immediately separating from plates after the transmission was shifted into the neutral position and some power could continue to be transferred from the engine to the wheels. The occurrences were intermittent, and it appeared that the brake clutch discs were overly flat, which could contribute to the delay in disc separation.
Toyota then made a change in the design of the brake clutch disc in order to change the level of flatness, however the verification testing of the design change failed.
November 2023 – February 2024
In early November, because the design change for disc flatness had failed, Toyota continued investigating the brake clutch disc mechanism. As a result of this investigation, a software change in the transmission control ECU was introduced at the manufacturing facility.
Following successful verification of transmission control ECU software changes, Toyota developed a testing plan to understand the customer usage scenarios along with any potential risks associated with those scenarios involving the condition. Before the testing plan was completed, Toyota received a field report that alleged movement of a vehicle in the neutral position while passing through a car wash.
February 15, 2024
Based on the results of the above investigation, Toyota decided to conduct a voluntary safety recall campaign.
As of February 13, 2024, based on a diligent review of records, Toyota’s best engineering judgment is that there are 5 Toyota Field Technical Reports and 1 warranty claim that have been received from U.S. sources that relate or may relate to this condition and which were considered in the decision to submit this report.
7. Description of Corrective Repair Action:
All known owners of the subject vehicles will be notified to return their vehicles to a Toyota or Lexus dealer. The dealers will update the software of the transmission control ECU, free of charge.
Reimbursement Plan for pre-notification remedies
As the owner notification letters will be mailed out well within the active period of the Toyota or Lexus New Vehicle Limited Warranty (“Warranty”), all involved vehicle owners for this recall would have been provided a repair at no cost under Toyota’s Warranty.
8. Recall Schedule:
Notifications to owners of the affected vehicles will occur by April 21, 2024. A copy of the draft owner notification will be submitted as soon as it is available.
9. Distributor/Dealer Notification Schedule:
Notifications to distributors/dealers will be sent on February 21, 2024. Copies of dealer communications will be submitted as they are issued.

SAFETY RECALL 24LA02 (Remedy/Notice)
Certain 2022 – 2024 model year LX600
Vehicle May Move While In Neutral Position
Frequently Asked Questions
Original Publication Date: February 21st, 2024
Q1: What is the condition?
A1: Certain parts of the transmission may not immediately disengage when the vehicle is shifted to the neutral position. This can allow some engine power to continue to be transferred to the wheels and can allow the vehicle to inadvertently creep forward at a low speed when it is on a flat surface and no brakes are applied, leading to an increased risk of a crash.
Q2: Are there any symptoms/warnings of this condition?
A2: No.
Q3: What is Lexus going to do?
A3: Owners of the affected vehicles will receive an owner notification letter via first class mail by late April 2024. Any authorized Lexus dealer will update the software for the transmission control computer FREE OF CHARGE to the vehicle owner.
NOTE (Guest who live in the state of California)
The State of California requires the completion of Recall Campaigns on emission related parts prior to vehicle registration renewal. In addition, the State requires that every vehicle must pass an emission test (SMOG Check) every two years and before it is sold. Without the completion of this no cost Recall Campaign, a vehicle in the state of CA may be more likely to fail this test. State of California regulations require Lexus to provide the Department of Motor Vehicles with a record of all vehicles that have not had the Recall Campaign completed.
A Lexus dealer will provide you with a Vehicle Emissions Recall Proof of Correction Form after the campaign has been completed. Please ensure you retain this form since the DMV may require that you supply proof that the campaign has been completed during your vehicle registration renewal process.
Q4: How long will the remedy take?
A4: The repair takes approximately 45 minutes. However, depending upon the dealer’s work schedule, it may be necessary to make the vehicle available for a longer period of time.
Q5: Which and how many vehicles are covered by this Safety Recall?
A5: There are approximately 12,100 vehicles covered by this Safety Recall.

VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect :
Description of the Defect : The transmission assembly in the subject vehicles uses a clutch piston to engage brake clutch discs to plates to transfer power from the engine to the wheels. There is a possibility that, due to an issue in the design of a certain brake clutch disc, when the transmission is shifted to the neutral position and pressure is removed from the clutch piston, the brake clutch discs will not immediately disengage from the plates, allowing some engine power to continue to transfer to the wheels. If this condition occurs when the vehicle is on a flat surface, and if the driver does not apply the service brake or the parking brake, it could allow a vehicle to inadvertently creep forward at a low speed (up to approximately 4 mph), which could increase the risk of a crash.
