Frame rust on 2001 Tundra

During recent service, the Toyota tech brought my attention to severe rust through on the frame of my 2001 Tundra (111,000 miles), even said it was unsafe to drive. After notification from Toyota about frame rusting problem an inspection was done by Toyota dealer in 2011 and I was told the frame was fine.
I contacted Toyota customer service (1.800.331.4331) on 6/26/19 and was told that my 2001 Tundra did not fall under any recall for severe rusting of frame but only a "limited service campaign" and that was fulfilled by the 2011 inspection.
Advice would be appreciated!

 

What sucks it's been 8 years since last inspection. A lot can happen in 8 years depending where that truck has been.

You got 18 years out of a vehicle known to have frame rust issues without taking any preventive measures. Sure as heck isn’t Toyota’s fault. I say this being the owner of a 2002 Tundra living in the rust belt. Mine is fine because I maintain the vehicle.

 

Sorry to threadjack; what have you been doing to maintain your frame from rust? I’m curious so I can do the same. Thanks

 

Fluid film and or grease rub for me. Fluid Film is very popular on this forum and works well.

 

Or boiled linseed spray is another option.

 

I apologize to all forum participants. Being an absolute forum newbie I started a new thread without searching for the existing threads.

In the last 8 years I have spent little to no time under the truck, Stupid, admittedly, as was placing my trust in Toyota. What I need are options beyond the initial negative contact with Toyota customer support. Who should I contact at Toyota? In addition any suggestions as far as commercially applied rust retardants would be appreciated.

Last fall took it to stealer for ‘inspection’ of recall. Get a call that the spray was applied (without my approval) to rear portions of frame which negates any further recourse for new frame replacement down the road. Fortunately, my frame was in great shape except for some small bubbles at the cross members tie in to C-frame.

Since the unapproved (by me) Toyotas film coating was installed I am SOL if the frame deteriorates. I have since gone overboard with one primer coating of Fluid Film on the other front portions of frame and then followed up later with a generous hand rubbing of all the frame with Moly-B Lithium Grease including the inside box frame.

Also, PB Blaster has been shot into all crevices that the straw can fit on multiple occasions.

Not sure if your frame was ‘coated’ in 2011, but if it was you are SOL on further recourse.

Post up some frame pics of your truck.
