I have a 2006 Chevy Impala and there seems to be a problem with the transmission. We have taken the car to the dealers several times. We have changed the spark plugs, changed and flushed the transmission fluid. We are still having the car jerk off at a stop light. We you are stopped on an incline it also hesitates to go into gear and the jerks away! the dealer can never find a anything wrong and we have done all the recommended fixes. This seems to be getting worse. The gas cap and solenoid have also had to be replaced which everyone has had problems with. GM should recall these cars before someone gets hurt!

Displayed on panel "reduced engine power". on star diagnosed service code "P2138". on 05/01/2012 while driving through a large intersection my engine power was reduced to 3 or maybe 5 mph. I was trying to get through the intersection without the acceleration that was so desperately needed. This is definitely a safety issue. In addition to being concerned about getting into an accident, I'm fearful I will be the one causing a fatal pile-up. I have been to the Chevy dealer 4 times and they were unable to fix this problem.

I have a 2006 Chevrolet Impala. The gas pedal sensor failed while driving at highway speed, causing a loss of power to the engine. The part is GM25830023. I have had this to a Chevrolet dealer to have fixed, but the part is unavailable from GM. According to the dealer, this is a common problem and they have 2 other Impala waiting for the part as well. I have been unable to use my car since April 14th.

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.
