1 Radiator Hose problem of the 2008 Toyota Highlander

Failure Date: 12/12/2020

I was driving my vehicle on a short trip on the highway with my eight year old daughter when a hose on the engine oil cooling assembly burst. This resulted in all of the oil in the vehicle being drained in a very short amount of time. No warning light came on as a result of this. I didn't discover the issue until pulling back into my driveway in which there is an incline. Then the light indicating low oil pressure finally came on. I opened the hood and found the dipstick to be completely dry. I also found a slow drip of oil under the car (only slow since it was only a small amount of oil remaining). I then discovered that the entire undercarriage of the vehicle as well as the back hatch of the vehicle were covered with oil. My daughter and I are very fortunate that the oil that covered the vehicle did not catch fire and as far as I know the oil slick on the highway did not cause any accidents. I am now being told by Toyota that this is a known issue, but it is not listed as a recall. Not only did their known engineering issue put my family and other families' lives in danger, they are also not willing to pay for the repairs of the damage to the vehicle that their known defect caused. There is a "warranty enhancement" that was issued by Toyota for this defect. According to Toyota the warranty enhancement notice was issued to the previous owner of my vehicle and I was not made aware of the issue. I have also had other work performed at the dealership since then and was never made aware of the defect or warranty enhancement. I am trying to understand how a manufacturer can know a defect exists that can potentially cause engine seizure, fire and accidents, but not issue a recall. Instead they limit the notice to a "warranty enhancement" which isn't caught by the dealership from a VIN check.

Engine oil cooling (rubber) hose burst while driving and dumped all of my oil . . . Toyota has since repaired this part with a series of metal pipes, which suggests to me that they realize that this is a defect but it is not acknowledged as a recall.
