My 2020 chev Malibu promised on the web site and on the msrp that it would get "29 miles per gallon in the city". this was also promised on the 2021 model. I have only gotten 24 mph or less in the city. The car is one year old. I have had three meetings & service check outs with the dealership and they tell me that that there is nothing that they can do. So, I need government intervention to fix my vehicle so that it gets what was promised.

Car lost power when passing a truck on the highway, hard start, immediately contacted dealership. They have had the vehicle for going on three weeks tomorrow. They haven't been able to diagnose the problem. I have contacted GM and the service representative at the resolution center said the dealership was not answering E-mails and he could not give us any information. The service manager at the dealership said he and the master tech had both driven the car and both said that they detected a problem. The service manager said the diagnostic computer showed excess, or unburned fuel in the #2 cylinder. The master tech said he put a bore scope into the #2 cylinder and saw a burned or discolored spot on the piston. The service manager said that a regional engineer had come down from spokane wa. And driven the car with another diagnostic computer. They still have not diagnosed the problem, and the dealer says that GM wants us to take the car back and drive it. We feel the car is unsafe and we are refusing to drive it. They are not coming up with a resolution to this safety problem.
