The contact owns a 2020 Toyota RAV4. The contact stated that while the vehicle was parked, coolant was observed leaking from the engine compartment with no warning lights illuminated. The vehicle was taken to the dealer where it was diagnosed that the engine casing had failed, and the contact was informed that the engine needed to be replaced. The vehicle was not repaired.

The contact stated that the failure was related to NHTSA Campaign Number: 20V064000 (Engine and Engine Cooling). The approximate failure mileage was 34,678.

Shortly after having vehicle serviced at Toyota the engine maintenance light came on.

But regardless I toke it to the Toyota dealer to have them diagnose the issue and under the advisement of the technician opt in for the repair so that my car “wouldn’t have more serious problems as a result [of not fixing the coolant bypass valve].” So now I have to pay $1000 for repair when I have had the car just the tiniest bit over 4 years (which is how long the warranty lasted).
