#8950 of 8952 Re: Sequoia exhaust manifolds warp by trucker01 Aug 10, 2009 (2:30 pm)
Replying to: cocoadogg (May 14, 2004 8:42 pm) This is a known problem and I have taken two different earlier model Sequoia's to the dealer where both were diagnosed in less than 10 minutes with having a warped exhaust manifold. This could be a potential life threatening problem as the exhaust gases could get into the passenger compartment and kill the passengers. If sufficient number of complaints are raised,with DOT a recall could happen.
#8951 of 8952 Toyota Sequoia & Tundra exhaust manifold warpping warrants a recall by trucker01 Aug 10, 2009 (2:47 pm)
This is a known problem to all Toyota dealers. I have taken two different earlier model Toyota Sequois to the dealers where both trucks were diagnosed in less than 10 minutes with having a warped exhaust manifold.   At the onset of problem, there will be an increase in the level of engine noise (promindue to the leak in the exhaust manifold). As the manifold warps further and the leak increases, the check engine light would come on as the level of Oxygen the Catalytic Converter Bank-1 will drop, and OBDII code of P0420 would reported.   All those who have had this problem should report this problem to the sites listed below, as well as to Toyota US, Toyota Canada, and Toyota Mexico   This could be a potential life threatening problem as the exhaust gases could get into the passenger compartment and kill the passengers. If sufficient number of complaints are raised and registered with the following organizations, a recall may happen:   Depart Of Transportation   National Highway Traffic Safety Administration(NHTSA)   Insurance Institute for Highway Safety (IIHS)   Transport Canada   Please note that fixing this at the Toyota dealer will set you backup $3000+ for each side of the exhaust manifold when using Toyota parts, then the manifold will warp again in a year or two!!!! You can try buying after market parts where the manifolds sell for $200 and the oxygen sensors sell for about $100, plus labour (a hit in the pocket of about $1000).

Replying to: tourguide (Sep 21, 2005 2:52 pm) I have a 2001 Sequoia 2wd with 39,500 miles of mostly local driving and a couple of trips from Los Angeles to San Francisco and L.A. to Las Vegas. The local mileage is 10 mpg and the best mileage on the highage being 17 mpg. I should count my blessings that so far I haven't had some of the problems that the other owners have had except the lousy gas mileage and the broken liftgate handle. Do I have to contact Toyota about the TSB bulletin on the brakes?
