Engine Coolant Bypass Valve faulty. Charged $176.95 for the dealer to diagnose what is already known issue. The dealer wanted $663 to replace the part. Toyota knows about this issue yet acts like they had to perform $176 diagnose. The car never blew any codes CIL and they say that this particular part doesnt cause a code but had to use a " special" diagnose tool.

Engine coolant bypass valve circuit short to battery or open - code P268115 Engine maintenance alert light appeared after (a day after, and then would not be on, and sometimes turn on, erratic maintenance message) I brought car in for scheduled engine maintenance per Toyota. The Toyota technician advised me to immediately take care of it but does not have the part in stock. This is the Toyota Dealer service in Manhattan Beach, CA.

Engine maintenance came on, took it to dealership and was told the diagnostic test showed coolant bypass valve. Apparently this is a recurring issue and if not taking care of, it could cause major problems. I was told the part is $200 plus and labor is $500 plus. This should be a recall issue and fixed free of charge by Toyota. In doing a google search, several complaints are listed regarding this issue. The gentleman at the dealership where I took my car stated he has done several vehicles recently with this issue. I don't think use as a customer should have to pay for this known issue by Toyota. I'm also still waiting to get the recall fixed on my mother's Toyota rav4 recall which I received notification on back in early 2023. Their excuse is not parts available. So in the mean time, if the vehicle catches fire, they say oh well. I am over Toyota getting away with this.

Fuel is not filling up all the way. Fuel has once splashed out when stopped automatically. Used to have around 445 miles per tank, but now around 395. It had started around 59000 miles. I have had the dealership inspect and see if their were engine codes but there weren-??t any. The time and care shouldn-??t stop just because the check engine light isn't on as it may be a safety or mechanical issue in the future. I would like my car to be looked into as it may be in line with the fuel pump issues on the 2018 Camry, a family member owned one that was recalled for a fuel pump replacement so maybe a Corolla wouldn-??t be to uncommon as well to have a know problem from the same company. I present with the utmost respect and hope I can get assistance and guidance on this minor issue as of now. Thank you for taking the time to read. Best Regards, A Toyota Corolla Hatchback Owner.

On March 2, 2019 I purchased a brand new 2019 Toyota hatchback from Toyota of richardson. After only owning the car for 3 weeks I received a notice from my vehicle's alert system that there was a safety recall on it. I was never told this by the auto dealer or by Toyota. The recall was due to an error with the manufacturing of the vehicle. In researching this, I found that in December of 2018 this recall was publicized on the world wide web and with NHTSA. The torque converters is defective and could cause a crash when the car has rapid acceleration. The vehicle could suddenly lose power while driving. My daughter, who is the co-owner of this vehicle, is the primary driver. She has 4 children, in which one is handicapped. She and her children has been at risk when driving and/or riding in this vehicle since the purchase date. So, for 3 weeks my family was at risk of having an auto accident due to a manufacturer's default in which a recall was issued 3 month prior to the purchase of this vehicle! yet the dealer did not take the time to fix this problem prior to our purchase. This is ridiculous!!
