I filled my gas tank (17 gallons), drove about 4 miles and was pulling into a parking lot when I heard a grinding sound, I looked under the truck and saw the straps holding my gas tank had snapped in half and my gas tank was laying on the ground. I had recently recieved a limited service campaign letter from Toyota notifiying me that "vehicles operated in cold climates with high road salt use may exhibit more-than-normal corrosion to the vehicles frame" "which may contribute to the development of more than normal rust in the frame of some vehichles". The dealership ordered new gas straps and also did the inspection which resulted in the under carriage being re-sprayed with a corrosion-resistant compound. I contacted thetoyota customer experience center at the dealerships urging and was told this was my fault, if I had brought my truck in for regular maintenance it would have been discovered and repaired. I have owned many vehicles and never had a gas tank fall off. My concern is this could have been at minimum an environmental disaster or at maximum an explosion could have occured.
