Well, I may never buy another Toyota again, unless they figure out a way to resolve this issue. Good luck to everyone who currently owns them. I did like mine, until this happened and how it was handled.
Just got off the phone with Toyota corporate for the 5th time this week. Spoke to a supervisor for an hour regarding the-
Failure of the Secondary Emissions Air Pump System and air pump valves in their 4.7L V8 engine.
Toyota Warranties Air Pump System - Reimbursement Available | Tundra Headquarters Blog
After arguing back and forth, and the guy literally telling me "we have documented cases on this issue and acknowledge there is a defect but we cannot offer a warranty extension on your vehicle at this time."
The conversation ended with this:
me: So your telling me, that Everyone who owns a toyota with the 4.7L V8, that has the exact same failed system, with the same defective components, that your company has acknowledged and extended assistance for on 2 other models, has to either come up with 4000 dollars or stop driving the vehicle because it either doesn't go over 45mph anymore and they now violate federal emission standards and will not pass emissions testing in my state.
Toyota: ( 20 second pause) Yes sir, the warranty only covers the tundra and sequoia. Although you have the same system we do not cover your vehicle at this time.
me: I want you to know that I am going to explain to the forums and groups i'm affiliated with that may number in hundreds, maybe thousands of people who are enthusiasts and take pride in owning your companies products that you market for being long lasting, reliable vehicles, may at some point have to shell out 4 grand to a dealer in order to pass emissions inspection and continue driving their trucks.
Toyota: unfortunately that is the reality at this time. When toyota feels it has enough complaints in a 90 day period they will contact the NHTSA and issue a TSB or a Recall. Unfortunately that hasn't happened for the 4runner specifically and we will not offer assistance for your vehicle.
me: but its the same exact defective part, that YOU deemed was defective from the factory.
toyota: Yes sir, please have your local toyota dealer repair your vehicle so you can go back to enjoying your truck.
Me: thats 4 grand..
toyota: yes sir.
