Toyota Innova Gas Tank woes

[Mile2]

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.

Is this limited to petrol or diesel only?

"That’s frustrating! If it’s a known issue, Toyota should address it transparently. Consider joining other affected owners to push for accountability or reimbursement, especially if it stems from a design flaw."

May i know what is the effect of his problem? Does it only waste your fuel?

I encountered a problem also but I'm not sure if it's related to this. My fuel gauge displays a warning light so i went to a gas station. I told the gas boy "full tank until 1st click" and so he did. Surprisingly, the nozzle clicked eventhough my fuel gauge only displays 3/4 filled. So I left there anyway and drove home. After several km i drove, i went back to the same station to have it refilled until 1st click. But still it stopped until 3/4 display of the gauge. He said that this kickback is normal if the nozzle detects pressure in the gas tank. Is this true? Have you experienced this? so i told him to continue refilling it and there, it clicked and gauge says full.

Any inputs will be appreciated!

fyi

lahat ng fuel tank meron breather for purpose of vacuum. Otherwise parang zesto yan. maging chicharon ang tank.

[Gecko Guy]

So does this mean sa breather ang problem?

[ghosthunter]

Yes, I was wondering about the same thing.

The fuel tank should not have a vacuum pressure inside. This could mean the fuel tank breather tube or breather check valve is either faulty or installed improperly (wrong direction).

[Memphis Raines]

Constant expansion/retraction will lead to metal fatigue.

This should really be addressed by TMP.

Thread is a sticky now.

Speak up and be counted.

Same problem here. Mine was replaced recently. Do you know where we can sell this defective fuel tank?

Actually the gas tank can be repaired using hot rod and lead. I have seen at the dealers service bay that they also repair gas tank via outside contractor, the contractor pulls out the defective tank and then returned after the repair. I ask the contractor and he told me he is from Paranaque and they would do a water immersion technique and hot rod with lead, "suplete" at "tingga".

Have you also replaced the "Charcoal Canister" and the "Filler Cap"? If not there is a huge possibility that your new gas tank will get warped and leak again just like what happened to me during my 1st gas tank replacement.

[Capsaul]

will you agree to "repair" the problematic gas tank? lalo na if under warranty pa? di ba dapat replacement at hindi repair lang...

i wonder if vacuum ang problem ... sa tingin ko kasi baka manipis yung material ng gas tank... dapat makapal na sheet schedule ng lata....


in the long run yung repaired gas tank sa ibang part naman mag warp yun... masisira din...

di kaya mine menos tayo ng TMC?

di pwede pukpok

Yup the "Charcoal Canister" was replaced and but still waiting for a new stock of "Filler Cap". Sad to say we have the same case, on my 1st fuel tank replacement, they didnt replace the charcoal canister and filler cap.
I'm looking for a buyer of these fuel tank. i have 2 pcs

Try calling Gant Auto Shop (2742-D Taft Ave., Pasay, T:831-6932) for the Filler Cap. Dito rin minsan bumibili ang mga casa pag sinabi nila sa iyo na by order ang hinahanap mo, panigurado meron sa Gant at mas mura. Kahit malilit na mga plastic clips meron sila.

Kabibili ko lang ng clutch cover, disc at bearing na all Toyota Original sa Gant last Saturday at ang laki ng savings ko compared to casa price. Sa Casa by order ang clutch set at ang mahal pa.

Mile2, how much ang total cost ng clutch cover, disc at bearing for the innova? Had my transmission pulled down by casa ( warranty claim ) last month to fix a squeaking sound whenever I depress the clutch. pero sabi ng warranty section wala dawpinalitan na parts. although nawala naman yung sound, I'm not sure kung kelan ito babalik.

madalang nagagamit ang innova namin. one day nagtaka na lang ako ng mag amoy gas yung parking namin at yun, may leak na pala ang gas tank. So mga masters, ano po ang da best na maipapayo nyo since na pede ulit ma warp ang tank pag pinapaltan. di bumababa sa half ang fuel nya kaya nagtaka na lang kami bat nagkaganun? napansin ko na kupi ang tank pero ala naman tama kaya imposible na may hard object na nag cause dun....

So ano po ba ang dapat na gawin? papalitan ang tank, canister & filler cap or iparepair na lang ang tank at magpalit ng charcoal canister at filler cap?

ano kaya ang masasabi ng toyota rito? aantayin kaya nila na magcause ng maraming aksidente ito bago nila gawan ng action?

If warranty pa unit mo, claim it underwarrty para walang cost. Pag na deny ng SA, punta ka sa CRO (Customer Relation Officer) doon mo habulin. Ako hinabol hanggang makarating ako sa Dealer's president pero inabot ako ng almost 2 months. Pag warranty 3 parts dapat ang papalitan (Gas Tank, Charcoal Canister at Filler Cap).

If out of warranty, have the tank repaired sa mga gumagawa ng radiator. Tingga at suplete ang gagamitin nila panghinang, mas maganda kung lalagyan nila ng reinforce sheet sa corner bend para siguradong walang leak. Yung big dent can be pushed back by taking out the Floater Assembly, then from that hole the dent can be pushed back. Then bili ka na lang ng Charcoal Canister at Filler Cap.

Hi! First time ko po mag post dito and I just replaced our tank about 3 months ago but before that I had the tank repaired sa shop, which didn't hold. pwede ko pa ba claim under warranty? at first akala ko may tinamaan yung tank pero the location of the dent made no sense then I read this post. May possible problem pala sa tank. nung pinareplace ko walang mention of a possible problem sabi ng tao nila tinamaan daw ng bato or something.

Ano pong variant ang unit nyo? Gas or Diesel?

Ano pong unit nyo? Innova, Fortuner or Hilux?

Pag nagpalit kayo ng gas tank dapat palitan din yung Charcoal Cannister at Filler Cap kung hindi uulit ang problem within few months. Kung di napalitan yung Charcoal Canister at Filler Cap, silipin mo yung gas tank mong bago kung may deformation na, pag may deformation na bilang ka lang ng ilang buwan at magkakaroon na ulit ng leak yan dahil punit na yung pinaka-kanto.

Ganyan din yung first gas tank replacement ko sabi ng casa tinaman daw ng bato kaya sa insurance ko pinadaan ang replacement. And then nagpagawa na ko ng skid plates to protect the tank pero umulit ang problem without a scratch sa skid plate, deform ulit ang gas tank while intact ang skid plates. Eto yung ipinalaban ko sa warranty claim on the 2nd gas tank, walang reason na tinamaan ng bato kasi buo ang skid plates.
