PLEASE READ FOR YOUR KIDS & FAMILY SAFETY This issue is a final destination that is waiting to happen if you do not have it fixed

*This could happen at any time. It happened to me at 171k. You will not get a warning and you will not even know to ask a dealer to look into it. The dealers will not fix it if there is no leak. You better have it replaced with the new part ASAP. The bulletin should be a recall, but for some reason it is not. It impacts other Toyota cars also. Read the bulletin link I provided below, contact your dealer or Toyota Corporation. AS I mentioned I never received this, I only found this when this issue happen to me. Frankly, I am nervous about other Toyota bulletins I am not aware of. This is out right scary *

The Car Problem:

From a loyal Toyota car owner in my 20 years of owning cars. The very first major major major issue and a total disappointment in feedback from Toyota customer service. I hope this helps someone else.

I received no warning, no notification in the mail, no lights lit up in the vehicle, no oil leaks in my drive way, no sudden noise in the engine. No one called me to say 'hey this $49 dollar part that you can buy on Amazon will spring a leak. When it springs a leak all of the oil in your vehicle will drain out while you drive. No smoke, no smell no nothing.'

I guess because smoke and oil goes under the car while driving. I made it home and then smoke appeared under the hood. I got lucky says the Toyota dealer where I had the vehicle towed to. See I was lucky because if I had driven 1 more mile or maybe a few more yards my engine would have seized because I had no oil in my engine. It all leaked out as I turn the corner into my subdivision and drove up to my house. I thought a neighbor was burning trash. However, it, was my Toyota Sienna.

I created two Support Cases with Toyota Customer Experience Center at their corporate location below. I spoke with Manda and an Operations supervisor. Unfortunate both representatives did not leave me with any satisfaction that anyone will look farther into this issue. Honestly, this issue should be a recall and not an extended warranty. This is just not the right answer you should be communicating with your support representatives, who then sends the same message to people who could have lost their lives, total loss of their vehicle, etc. There was no empathy in either voice as they consistently blamed me for this issue.

Hey everybody, I got lucky my family of 4 did not DIE (engine could have seized) while passing an 18 wheeler on my 1200 mile round trip from NC to GA during XMAS eve. Also lucky I did not kill someone who was riding a motorcycle as 5 quarters of oil spilled out of my engine on US and Interstate highways. Hey I was lucky.

Toyota Corporate do the right thing and send out a mass communication globally to notify owners of any vehicle who has this defective part updated. Since I made it, let's not let this happen to others. A warning notification could help since this issue is already known by Toyota.

I had to fight with the dealership to reduce the cost from $650 to $450. Of course, they tripled the price of the part and labor. Hey, Toyota since this is such a serious issue you should reimburse customers who shelled out to fix something that should be a recall, but if you don't a nice call or mail from an Executive would do me fine just so I know these tickets I raised or not lost and the Toyota product is being engineered better. One other thing to note as to why this issue should be a recall is because you redesigned the part from plastic/rubber material to a metal material.

I created Support Case number: 1801100093. I then created a new support Case after my disappointing call with Manda:1801100093.

That's all folks.

Sienna XLE

  • Automatic transmission
  • 109,000 miles

Car started leaking oil heavily. Low oil pressure light came on as I drove into Firestone lot, but made it there before engine locked up. Told oil cooling hose had failed in two places and had to be replaced. New oil cooling hose made of aluminum. Old hose was rubber connected to metal plates and failed in two places in the rubber part. Techs checked for recall because the new hose was different than the one in my car; no recall was found. This was not a bigger problem because I noticed it quickly and was able to get in to the shop before being stranded somewhere with kids.
