Open the full vehicle complaint log (all categories)The Cylinder head gasket in the engine has failed and is now leaking coolant under the body of the car. This has been inspected by a certified Toyota Dealership and has been maintained by one since we bought the car. There were no warning signs or problems with the car other than feeling off (sounding slightly different than normal) so we went to get an oil change and inspection done on the vehicle. This car was just serviced three months prior for regular maintenance and the vehicle had no indicated issues at that time and was inspected again by the same Toyota Dealership. The vehicle is available for inspection. This issue seems to have started very suddenly without warning and will cause severe engine damage in my vehicle if not replaced soon.
