ENGINE AND ENGINE COOLING
10/07/2009885671
 I took my 2001 toyota tundra to the mechanic because the exhaust system was getting noisy. when the mechanic had the car jacked up, he noted that the frame was extremely rusty on the driver's side in front of the back tire. it was actually almost rusted through. he said it looked like it could break at any minute and got away from the vehicle. i contacted the dealer where we purchased the truck who said i should drive it down for them to inspect it. i refused because of the safety issue nothing has been done at this point and the truck is still at the mechanics. *tr

 Took vehicle to dealer on 11/13/2002 with check engine light on. dealer performed check and determined 2 02 oxygen sensors were bad. said they would order them and call me to bring vehicle back in. check engine light still on continuously. engine speed rises and falls with no pressure on accelerator. when in gear, sudden engine acceleration causes vehicle to jump forward unexpectedly it is now 12/3/02. dealer says sensors have not come in. when questioned as to whether this sensor problem is common with all toyota trucks with 4.7 liter v8 engine. the service man was evasive saying there have been some problems. considering they are having to order a part that is normally stocked at the dealership, and considering the unusual length of time it is taking them to replace the defective sensors on my truck. i am of the opinion that this is a widespread problem with the potential to cause accidents. this problem should warrant a recall of these type vehicles to correct this safety problem. dt

 2001 toyota tundra 32,500 miles, both exhaust manifolds are cracked, the dealer states that the car is out of warr. after a month of back and forth with toy. main office. they tell me they will pay labor and 1/2 part,i pay the rest ($350). this is a design problem exhaust manifolds don't crack, this problem is the fist line in the msn review of this car & all over the web. what does it take to get satisfaction & reliability from toyota just admit there's a design problem and fix it..*jb
 Consumer called complaining about having problems with the exhaust manifold. also stated that it has a crack that will leak into the engine instead of the exhaust pipe was contacted and will only replace it if the vehicle is under warranty.
