Toyota Rav4 2019 XLE - Engine Coolant Pump Performance/Stuck Off Error code P26CB milage 56,920 Toyota says this is NOT covered by the 5 year power train warranty. For years Toyota has manufactured this water pump that freezes up due to manufacturing defect that allows the magnetic base housing to rupture. Dealers want to replace entire pump (or at least charge for it) verses replacing the frozen plastic rotor. Dealer claims this is not covered under 5 year power train warranty. Why not? My car temp started climbing and took me hours to get home (10 miles) as I kept stopping for hours waiting for engine cool and sprinkling water from bottles over the engine and trans housing where it butts against the engine (silver brading). (This was late in weekend night - repair shops not open. I do see a recall investigation started (no recall yet) and just wanted to add my complaint to the issue. At first the temp gauge read normal but later started climbing. The engine light did come on the the DB2 said P26CB.

Upon reaching 50k miles, vehicle prompted a "engine maintenance required, please contact dealer" message. Upon inspection at the dealer, I was told this is a common issue in newer Toyota RAV4/Corollas and employees have been seeing this issue continuously. There is no way to bypass this message without getting the part replaced and the replacement runs anywhere ~$800 -$1000. How are so many people dealing with the same issue and Toyota has yet to issue a recall?

Hi there. As of June 17, 2024, there is a class action lawsuit against Toyota regarding issues with the coolant bypass valves in the 2019-?"2023 RAV4 and Corolla models. Some owners have reported that this defect could affect the vehicle's performance and longevity, potentially leading to expensive repairs. The plaintiffs allege that Toyota has violated the Magnuson-Moss Warranty Act, the Florida Deceptive and Unfair Trade Practices Act, and California's Unfair Competition Law, Consumers Legal Remedies Act, and Song-Beverly Consumer Warranty Act. They are seeking a jury trial, declaratory and injunctive relief, and punitive damages. I encountered the same issue on July 3, 2024, and visited Toyota Scott Clark (Charlotte), where I was charged $129 for diagnostics and $835.60 for further service to fix the problem. I am not willing to pay for this service, and Toyota has refused to cover the cost. I am joining the class action lawsuit against Toyota.

Coolant bypass valve

My engine maintenance light will not shut off due to a engine coolant bypass valve circuit short to battery. I also have warm fluid dripping on my feet when ac is on. The dealer says water under the dash is from from recalled roof rails. There has been a recall for code that pops up on my mechanic Toyota number20TA04. Dealer says he does haven't code so toyota hasnt issued any issues or re all for engine bypass valve. Toyota now has a class action law suit for this part. I can't afford $700 repair, can't see the messages or my speed due to the engine maintenance required on my screen which can't be reset. This is dangerous and can cause the need to have engine replaced, start engine fires. Toyota has known this issue for 5 yrs and needs to be held accountable.

Coolant Bypass Valve Defect. Toyota sold me a 2019 RAV 4 knowing there are problems with coolant bypass valve. Toyota RAV4s and Corollas is -??insufficiently manufactured and/or designed-?? as it can crack and leak coolant. Once a leak begins, the coolant comes into contact with an electrical connector near the valve and corrodes and damages the component, the filing says. Once this occurs, a vehicle-??s engine can no longer communicate with the coolant bypass valve during operation, the suit states.

A message popped up on my dash "Engine Maintenance Required - See Dealer". After further research this is a known issue with the Toyota Rav4s. The coolant bypass valve gets stuck open/closed. I took it into Toyota and before they even looked under my hood, he read the message on the dash and said "I know what it is". After paying $742.16, it was fixed. My local mechanic was not aware of this issue, so I had to go through Toyota directly. If someone cannot afford $700-$1,000 repair, they risk their engine overheating. Toyota is aware of this issue and they have not recalled this part in their vehicles that is consistently failing.
