Here's another problem with Innova gas tank and I knew Toyota Phils. knows this problem and still keeping their silence.
Here in Tsikot, there are already a lot of owners who do experience this problem not just once but twice or three times during the warranty period. But some like me have shoulder the cost of replacing it because I'm not aware that this is due to faulty design and components.
Here's my first gas tank, replaced using my Insurance claim and paid for my participation. Toyota only replaced my gas tank assembly.
Then after less than 9 months, the gas tank again warped on the same spot. This time I already knew that this is a real defect from components and negative pressure build up is flipping my gas tank floor inward, I tried opening the gas filler cap and instantaneously a loud flipping sound of metal from the gas tank could be heard. This explains the cracks and fuel leak, the constant flipping out and flipping in of gas tank floor weakens the cornered portion of the gas tank just beneath the front strap.
Here's the picture of my second gas tank, claimed under warranty that took me around 2 months to battle my claims with TMP. See how deep the the dent on the gas tank floor due to negative pressure. Together with replacing my gas tank, TMP also replaced my Charcoal Canister assembly and Filler Cap. I'm still hoping it won't happen again
Picture of warped gas tank showing how large is the dent due to negative pressure.
Other owners who experienced this, just show up and be counted, and to other owners who will experience this and your unit is still under warranty, be firm to claim it under warranty as this is really due to faulty components.
To the moderators, please have this thread sticky to warn others and to let them know that they should claim it under warranty.
