Back in 2010, car shut off while accelerating onto freeway. Took into chevy, could not duplicate & didn't fix. Happened 3 more times over 2 years, finally took it in 2012. Dealership shop said it was a faulty oxygen sensor in fuel line. Happened on listed date of incident in rush hour traffic, driving less than 20mph. Vehicle completely shut off. Have not taken it back to be looked at.
My step daughter bought a brand new Aveo 2009 is has been in for repairs 13 times for the same problem. It will run fine then will not go over 20mph this has happened several times while she is driving on highway at 65 mph has almost caused her and my young granddaughter to be injured. When she starts the car the clock will reset its self to 7:23 no matter what time it is that is usually the first sign it is getting ready to turn into a death trap. O2 sensor has been replaced car is again in shop they are telling her they can't find any problems but think it could be the O2 senser want 600. 00 to replace. Her check engine light has not come on. Car is no longer under warrenty. We have contacted dealership where she bought it no help from them. Contacted chevy asking them to admit it is a lemon and do the right thing no help from them.
