2007 Toyota Tacoma suspension problems

On march 24th I drove to a neighboring town about 120 miles away in my new toyo tacoma 4x4 2007. I did my shopping, and every time I exited the vehicle I would smell the odor of burnt rubber. I would then inspect my tires (exterior) and there did not appear to be any problems. I drove home that evening okay, but when I arrived at home, I again smelled the burnt rubber odor. The next day, I used the truck off road to get a bundle of firewood (under 15 pounds).

Took my 2007 toyota tacoma to the dealership because of squeaking and the smell of burn metal. The service agent said there is a service bulletins(tbs 027409) the rear leaf springs are defected as she said. Toyota would only fix the problem if it was under warranty. But since my was out of warranty I would have to pay for it. I told her that if the vehicle has a defected problem why was I not in front of it at the time it was issued. She said if toyota inform every one it would cost toyota alot of money.
