This happened to me at the beginning of January.
Capitol Toyota Service wants $3500 to fix it because they said they have to drop the prop shaft, transfer case, and transmission.
They said the line was $168 and all the other cost was labor. They also mentioned that I had two options, I could do it myself if I'm able to, or I can talk to insurance if I don't want to pay for it. They said warranty does not apply here since it's impact damage.
This is sketch asf because it sounds like they just don't want to be reimbursed at Toyota's shop rate but if they do it as a customer repair they can bill a la carte for it. I told them I shopped online for the part and it's $56 for the line. They dropped the price to $118. I paid to get it towed back home. This is the 3rd tow.
Once home to do diagnosis for myself.
Once to the dealership so they could do the diagnosis ($298)
Once back home because no, I'm doing this myself.
Thanks to
@WookieBait for referring me to the existing threads.
On another dealership's advice, I reported the incident to the Customer Experience Center. 1-800-331-4331 and obtained a case number as they escalate and investigate.
On
@Blue Bear 's advice I've also reported this to NHTSA.
@misnMy4runner 's case where their tank emptied out on the road way could potentially cause a Back to the Future style fire. Depending where and the time of year, it could be catastrophic. I recommend everyone else report this issue to NHTSA if you've had a similar situation.
Imagine you're casually going through a fire road in late spring when everything is parched already, you hit a patch of standing water and the clip flies off. You begin leaking fuel all over the forest road when it catches fire due to static or hot exhaust or something. The entire forest could go up in flames.
The main issue is that Toyota switched from common steel spring clips to this type of convenient connector for easy service. The other compounding issue is that the way the tanks are mounted, they're actually suspended from the frame with straps to limit downward movement. However, upward movement is not limited because the expectation is that if someone offroads their vehicle, you might find yourself in a situation where you might get high centered over snow, rocks, or another obstacle. The fuel tank, in a method of preservation, would gingerly move upwards as your vehicle skedaddles over the obstacle to prevent a puncture. However, if you hit water at expressway speeds (45mph+), the tank will slap the line connector against the chassis and pop the clip.
If you were to say get a solidly mounted fuel tank, like say one that offers 29 gallons of capacity, it might have a higher puncture risk, but due to its larger footprint and solid mounting, it should shield the fuel line from this type of activity.
I ordered two fuel lines, I intend to scan the connector section and 3D print a clamshell clamp to secure the retainer clip.
This should be a good interim unless Toyota gets off their ass and issues a recall to fix this.
