Toyota Engine Coolant Bypass Valve Recall

This Customer Support Program is for the infamous "Coolant Bypass Valve" failure that plagued 5th gen RAV4s and many other Toyota models. You get the "ENGINE maintenance required" notice on the MID when the valve malfunctions. The coolant bypass valve defect in the 2019-2023 Toyota RAV4 and Corolla models highlights a serious issue within Toyota's quality control processes.

As the legal proceedings continue, affected owners are encouraged to stay informed and consider their options for potential compensation or repair. Some 2018 - 2021 model year Toyota vehicles equipped with an A25A-FKS, A25A-FXS, or M20A-FKS engine may exhibit a condition in which an "Engine Maintenance Required" message is displayed in the Multi-Information Display (MID). Additionally, the vehicle will exhibit DTC(s) P268111 (Engine Coolant Bypass Valve Circuit Short to Ground) and/or P268115 (Engine Coolant Bypass Valve Circuit.

If you have the Engine Maintenance Required warning, it might be worth checking with your dealer to see if the bypass valve replacement is covered, as it seems Toyota has extended the warranty for this issue. A class action lawsuit alleges 2019. Toyota allegedly concealed the problem, and without a coolant bypass valve recall customers are stuck with paying for costly repairs that don't fix the problem which will allegedly continue to occur.

Coolant smell, weak A/C, dash filled with warning lights, yet no recall. Toyota's CSP 24TE04 targets a hidden flaw: a leaking coolant bypass valve that shorts its own circuit and quietly nudges the engine toward overheating. The fix is covered, but only if your RAV4 was built before February 2021, and you know how to claim it.

This new support program will give a free coolant bypass valve replacement for specified 5th gen RAV 4s when you get the dreaded "ENGINE maintenance required" MID screen warning. There is a NEW valve with a NEW PART # which hopefully is better than the old 16260. The bypass valve can malfunction and get stuck, either open or closed, causing the RAV4 to display the dreaded "Engine Maintenance Required" (which is different than the 'Maintenance Required' light).

The valve can also develop cracks, allowing coolant to contaminate the electrical connections, causing it to fail.
