The coolant bypass valve has leaked. It is available for inspection upon request, however this seems to be a larger ongoing problem across the country with this make, model and year. The check engine light did go on.

The -??Engine Maintenance Required-?? light came on, indicating issues with the coolant valve. This is become a common issue with the RAV4. If this is becoming a common issue for owners, it needs to be looked into!! I commute and my engine can overheat.

Engine: I got the 100k engine maintenance done. I replace my coolant and got an oil change. The engine maintenance required warning is still on my dashboard and will not go away because the diagnostic reader states I need a new coolant bypass valve. This is not apart of the factory maintenance, alot on rav4 owners are dealing with this, and it is very pricey. I think it is best for this type of situation to be recalled. Brakes: I got my front brakes replaced and I had issues with my front calipers. My mechanic said both calipers had holes in them and caused my brake fluid to leak which has affected my braking alot. It takes a long time to brake and I-??ve experienced this even after I-??ve paid alot of money to get my driver said caliper replaced, still need to get my passenger side replaced. My mechanic only uses toyota brand supplies so I-??m not sure why there isn-??t any longevity in the quality of supplies. I-??ve only had the vehicle for 2 years.

Defective coolant bypass valves on my 2019 Toyota RAV 4 have caused coolant to leak out of my vehicle-??s closed-loop coolant system, harming its ability to properly regulate engine temperature. Eventually the message -??Engine Maintenance Required Visit Your Dealer-?? appeared on my dashboard indicating an issue with the engine. An internet search of this error message on the 2019-2023 Toyota RAV4 and Corolla models shows this is a widespread defect, affecting hundreds of Toyota owners. A class action lawsuit has been filed against Toyota regarding defective coolant bypass valves in the 2019-2023 Toyota RAV4 and Corolla models [XXX] et al. v. Toyota Motor Sales, U.S.A., Inc) but Toyota has still not addressed this defect with a recall. Attached is a copy of the mechanic invoice I just paid to replace the defective coolant bypass valves on my 2019 RAV4 as the engine was not maintaining temperatures appropriately and in risk of total engine failure.

My 2019 Toyota RAV4 had been making a loud noise at random intervals when driving at high speeds such as freeway speeds. The dealer said they could not reproduce the issue. A couple years later at around 65000 miles my engine maintenance required message came up and would not go away. I took my vehicle to get the code read and there were no codes. I kept smelling fuel or different unpleasant smells when driving the vehicle. The engine maintenance required notice would turn on every single Time I used the AC. I later went to the Toyota dealer and they said the coolant bypass valve had been leaking and causing the engine maintenance notice to come up. This is a new vehicle that has been maintained properly and rarely driven far. The part and labor was $824.

Coolant valve failed ($700)shortly after warranty ended; extended warranty did not cover repair. Coolant valve then caused harness to be unusable causing for a $4500 part replacement to be required. During the whole process the Toyota dealership maintenance told me that the engine repair required alert was for normal maintenance and directed me to continue driving with it until my scheduled service every time after speaking with three different people and a mechanic at the dealerships maintenance shop. I was then told after bringing in the car that I could leave although the alert was still present. Finally after the maintenance supervisor looked at my car I was told it was not safe to have been driving. Toyota made a faulty part that they expected to break and still put it in vehicles. They then are not even aware/ do not acknowledge this widespread issue in 2019 and 2020 rav-4s and Carrolas. This defective part can cause the engine to have catastrophic issues as I was later told by the maintenance manager at a Toyota dealership. However, Toyota is leaving car owners and leaders out of thousands of dollars in repairs and not acknowledging or warning customers of a dangerous issue.

I got an alert on my screen that would not go away. It said Engine Maintenance Required.-?? Went to auto one & there was 0 diagnostics associated with any codes. The guy said that it is the coolant bypass valve and that there is a class action in the works. He said most places charge $600 - $700 to replace and to hold on to my receipts.

Out of the sudden, the engine light started to display a message to check engine and overheating of this took place continuously. My Rav 4 only has 70k miles and I got it pre-certified from the dealer. This error is the Coolant Bypass Valve. This Valve is connected to a radiator hose.

A warning message appeared that stated: -??Engine maintenance required - Visit your dealer-??. At that time my vehicle had 38,796 miles on it. I contacted the Service Advisor at Toyota of Newnan who advised that it was likely the Coolant Bypass Valve on the engine and that they have had issues and repairs relating to that condition on their RAV4 and Corolla models. Their mechanics confirmed that this was the fault and that failing to have it repaired / replaced could result in engine overheating and engine seizing which could result in lose of vehicle control and endanger other vehicles on the road. Sensing the urgency, I had the repair / replacement completed at a cost of $846.68. Service advisor stated that many of the other vehicles with the same problem were still under warranty and repaired at no cost to the consumer. In my opinion this recurring defect among two Toyota model lines is occurring with enough regularity to warrant Toyota issuing at least a Service Bulletin and covering the cost of the repair and reimbursement to those that had to pay for the repair.

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.

Coolant bypass valve

- Aurora, IL, USA

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?

Coolant bypass valve failure The issue has been confirmed by a service center and was told a very common failure in my make & model of car. Warning light came on dash board and immediately had checked at service center. The fix is $900, which is frustrating because a class action lawsuit is being gathered for this same defect in my same model of car.

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.
