| Driving to my home on thursday, august 4, i heard a rapping noise start in my engine. i had taken it to the garage (d&j auto) the following day. upon there inspection, they found a hole in the block of my engine. after swapping engines out of my vehicle, i had further inspected the old engine. i had a certified mechanic friend helping me to tear down the engine to find what caused the problem. we had found that a connecting rod had shattered inside the engine (arm that connects piston to crank shaft). i had contacted toyota motor corp. and a few service managers in my area to send a representative to come and inspect the damage. i was told by a certified mechanic that the metal casting of the connecting rod was faulty, i thought toyota would want to verify this by inspecting the pieces themselves. i have not been contacted by a toyota representative as of yet and it has been three weeks and the service managers keep saying; the engine is out of warranty so there is nothing they can do for me. if i would have been driving this vehicle on a major highway this problem would possibly have caused a serious injury or accident to me or others. i felt since they would not acknowledge me, it should be reported to you. i have documented the damage with digital pictures and i am in the process of having the pieces analyzed by an independent mechanic to determine the exact reason for the failure. *nm | |||

| I had a 1999 toyota tacoma. this truck was a 2wd with a 2.4 litre engine extended cab. the accelerator was always high. i got a few speeding tickets because of that. even on small roads the rpm was unusually high. the mechanics also used to comment when they would do maintenance work on that truck. i lost this truck in an accident now. but please investigate this model also. also the egr valve on this trucks go bad frequently. thank you for investigating toyota. i thought i had a fluke bad toyota truck, but it turns out that i was not alone. thank you for your help. *tr | |||
