| My 2001 toyota sequoia had an issue with check engine light at approximately 77,000 miles. it pulled the p0155 code that indicated failure of oxygen sensor. toyota had at least two technical service bulletins on the issue showing this problem as widely known. what is more, on tundra vehicles (that have the same engine)toyota recognized the issue by extending the warranty on sensors and on that specific code up to 90000 miles. the repairs cost was almost $340, pulling the code (5 min) and replacing the sensor (15 min) was charged at 2 hrs of labor. toyota customer service refused to cover repairs. customer service case 2007-07250397. *tr | |||

| We have a toyota sequoia, the problems are the 4 wheel drive is not operating all the time. it does not engage sometimes and does not stay in 4 wheel drive. one example is my wife had six friends in the vehicle the 4 wheel drive did not stay engaged and the vehicle skid control made the engine loose power so she slid backwards down a hill. no one would ride in our 4wheel drive again. the vehicle skid control makes the engine loose power while in traffic. there is also a hesitation in the engine when accelerating from a complete stop. another problem is the braking system is not adequate for the vehicle. the entire front brakes had to be replaced. the vehicle has been in for the same repairs at least 10 times and is still not working the way it should. we have all the documentation for service on our sequoia. we have done internet research through nhtsa and have found the same problem with other toyota sequoia's. there was also a problem with the air conditioner having a bad oder from bacteria growing, the exhaust manifold was loose and the power window motors made a loud noise. we have filed a complaint on all the same problems with nhtsa, comsumer affairs of california and you. we want to pursue the lemon law and get our money back. we are currently working with toyota arbritration but are getting nowhere. we have had toyota's previously and had no problems with them. this vehicle is a lemon. | |||

| Brought in car to have muffler checked out and my mechanic called me back after putting car on the lift. there were rust perforations the size of a football as well as openings along the whole frame. the mechanic told me it was unsafe to drive and that this was not normal wear for this vehicle. he was concerned that the drive train would fall through if we went over a big enough bump and cause an accident. the rust was abnormal and he said that it looked like it was rusting from the inside out of the frame. i called toyota to file a claim and they had me bring it to the local toyota dealer. they refused to send out a regional rep to look at it saying it was not under a recall of any kind. now my car is unsafe and worthless. the toyota corp. customer service told me to sell it for parts.... really??? they did nothing and offered no answers. please research this problem and get something done about it. does someone have to die to get the attention? you buy a toyota for its longevity and quality. i will never buy a toyota again. *tr | |||

| Bought november 4th 2000. new tires at 20000. smelled exahust when vents are in recylce mode. have a damaged exahust manifold at 55,000. dealer has sated that none of these are under warranty. i have heard of other people having same problems. i buy toyotas for reliablity and service. i feel that i have not had the service nor the reliability expected. it would be a good sign of committment if totyota does honor a solution to these two problems, exahust manifold/exahust entering cabin. *ak | |||
