I have 644000 miles on my Toyota Sequoia SR5 and the ac stopped. When I took it to the dealership where a continuously serviced it, they determined that I would need a complete new system for $2500. I immediately called Toyota headquarters and they told me that I was out of warranty and "out of luck". What amazes me is that so many other sequoia owners are experiencing the same thing.
Toyota headquarters explained that the problem was, you should not turn the rear ac on before you turn the front one on. Shouldn't they have put this in the manual???
Was the mileage actually 644,000 miles or was that a typo? If 644,000 was actual mileage I'd expect at least the AC to be replaced maybe twice over. GT.
The system probably just needs recharging which you can do yourself if it's a R-134a system, although it might be worth getting an air conditioning shop to check the system for leaks.
How is it "SCARY" that the A/C went out? I clicked on this review thinking that there might be a safety concern... darn it.
It's amazing that your Sequoia is still running with 644,000 miles. You must have a long commute.
Is the original engine still in it?
Come on people, that mileage has to be a typo! Do the math... the vehicle is an '02 and the review was written in 2006. 644,000 miles in 4 years comes out to 161,000 miles a year, (13,417 miles a month or 447 miles a day, every single day)! Impossible! I'm certain the reviewer must mean 64,000 or maybe 64,400 miles.
