Tank Assembly problems of the 2006 Chevrolet Impala

My complaint probably does not warrant a recall, but should be handled by consumer notification. My 2006 chevy Impala has developed a fuel related problem that causes the check engine light to activate. This is caused by the use of e-85 fuel. The computer detects high alcohol content in the fuel. The dealer was able to solve the problem with both a software update and by flushing out the e-85 from the fuel system and resetting the computer. The cause of this problem was lack of proper instruction, from the dealer, in the use of e-85. I have been instructed that after filling the gas tank with e-85, the vehicle must be driven a minimum of 11 miles, before shutting off the engine. This gives the sensor in the fuel system sufficient time to adjust to the fuel. This needs to be done every time the vehicle is switched from conventional e-10 gas, to e-85. I was unaware of this procedure, until after the problem had occurred. Gm should notify all consumers who have purchased 2006 and 2007 vehicles equipped with flex-fuel engines of this requirement. After the problem occurs, the dealer needs to perform the reset procedure for the fuel computer. This procedure requires approximately three hours. It is not a serious defect, but it is unnecessary. The dealers should inform customers, when the vehicles are delivered, of this procedure.

: the contact stated an object was dragging under the vehicle. An independent repair shop determined three of the four plastic clips that held on the heat shield were missing. The repair shop made a temporary fix with plastic ties. The vehicle was taken to the dealership who replaced the heat shield and fuel tank.
