2021 Toyota Flow Shut-off Valve Coolant Leak Program

Toyota has initiated Customer Support Program 24TE04 to address a potential issue with the flow shut-off valve, which can lead to a coolant leak in various 2021 Toyota models. This program aims to ensure customer satisfaction by providing coverage for necessary repairs.

Why this matters

A small engine coolant leak from the flow shut-off valve can cause coolant to drip onto other parts of the vehicle. This condition may trigger a "Maintenance Required" message on the instrument cluster or cause the air conditioning system to malfunction. Addressing this issue promptly helps maintain vehicle performance and prevent further complications.

Symptoms

Owners may observe a small engine coolant leak originating from the flow shut-off valve. This can lead to the following indications:

• A "Maintenance Required" message displayed on the instrument cluster.
• The vehicle's A/C system not functioning normally.

What's being covered

Toyota's Customer Support Program 24TE04 provides extended coverage for repairs related to the flow shut-off valve coolant leak. The primary coverage is valid until November 30, 2025, regardless of mileage. Secondary coverage extends for 10 years from the vehicle's date of first use or 100,000 miles, whichever comes first. This program covers approximately 2,384,700 vehicles, with about 17,000 distributed to Puerto Rico.

Important Warnings

Toyota has issued specific instructions regarding this program:

• Dealers SHOULD NOT increase their stock of related repair parts. Dealers are requested to only order parts for vehicles experiencing this condition only. DO NOT ORDER FOR STOCK.
• This Customer Support Program is emission-related. Therefore, vehicles branded as salvage, total loss, true mileage unknown, or similar titles ARE ELIGIBLE for coverage under this CSP.
• Claims for repairs performed by non-qualified technicians are subject to debit.
