2018-2021 Toyota Models Coolant Leak Program 24TE04

Toyota has initiated Customer Support Program 24TE04 to address a specific condition involving a potential engine coolant leak in multiple models and model years. This program aims to resolve issues stemming from a faulty flow shut-off valve that could lead to coolant dripping onto other vehicle components.

Symptoms of a Coolant Leak

Owners may notice a few key indicators if their vehicle is affected by this condition. The most common symptom is the illumination of an "Engine Maintenance Required" message on the instrument cluster. Additionally, the vehicle's air conditioning system might not function normally.

These symptoms are typically caused by a small engine coolant leak originating from a specific valve. The leak can allow coolant to drip onto other parts of the vehicle, leading to the observed warnings and malfunctions.

Affected Components and Diagnosis

The core of the problem lies with the flow shut-off valve. This component, or the associated Hose Assy, Water-Bypass, is prone to developing a leak. If you suspect a Toyota Camry coolant leak or similar issue in another affected model, a Toyota dealership can diagnose the condition.

Diagnosis involves inspecting for coolant dripping from the valve. If the condition is verified as being consistent with the terms of Customer Support Program 24TE04, the necessary repair will be performed.

Repair Procedure Summary

Should the condition be confirmed, the repair involves replacing the faulty flow shut-off valve with a new one. This procedure is designed to permanently resolve the coolant leak and prevent the recurrence of symptoms like the "Engine Maintenance Required" message or A/C performance issues.

The repair is estimated to take approximately two hours. However, the total time your vehicle is at the dealership may vary depending on their work schedule.

Coverage Details

Toyota's Customer Support Program 24TE04 provides comprehensive coverage for this specific issue. The primary coverage extends until November 30, 2025, without any mileage limitation. Following the primary coverage period, a secondary coverage is available for 10 years from the vehicle's date of first use or 100,000 miles, whichever occurs first.

This coverage applies to work performed exclusively at an authorized Toyota dealership. It is subject to the standard terms and conditions outlined in the New Vehicle Limited Warranty Section of the Owner's Warranty Information booklet. Damage resulting from abuse, accidents, theft, or vandalism, for example, is not covered under this program.

Important Warnings for Owners

Owners should be aware of a few critical points regarding this program:

• "If the condition is not covered by this Customer Support Program, you may be responsible for the initial diagnostic fees and any other repairs you may decide to have performed." It is crucial to confirm coverage with your authorized Toyota dealership.
• "If an owner has not experienced the condition, he/she is asked to tear off the sheet included in the owner letter and insert it into the Owner's Warranty Information Booklet for future reference." This ensures you have the program details readily available should the issue arise later.

Owner Action

If you own an affected Toyota or Lexus vehicle and experience symptoms such as an "Engine Maintenance Required" warning, A/C malfunction, or suspect a Toyota Camry coolant leak, you should contact your local authorized Toyota dealership. They will perform the necessary diagnosis and, if the condition is verified under the program, the repair will be completed free of charge.

Toyota will begin notifying owners by first-class mail starting in late December 2024. If you have any questions or concerns, you can contact the Toyota Brand Engagement Center at 1-800-331-4331.
