I have one whale of buyers remorse. Seems it wont go away. Maybe Sonic needs to go. Transmission works when it wants to, fails to downshift into lower gear when its needed. The automobile has the worse value for a car with 12 thousand miles on it and new Michelin Pilot tires
The roof has been painted, suspension parts have been replaced. Car runs ruff in neautral as well in drive idling, have rectified some of ruff idle I use 93 octane seems to help somewhat also synthetic oil has helped to. Gas mileage is just a couple of MPG than my 2000 Nissan Truck, and the truck you couldn't tell it was running. The Sonic idles like the 4 cylinders of 20 years ago. GM should be shot. Selling such junk
hate to say it but its paid for
Better motor or mapping. improved transmission.
some motors are from Korea same with Trannys. some are mixed. Does Daewoo ring a bell. Some of the parts are made in Korea as I said by Daewoo. One of GM's co.'s abroad. Daewoo was junk here. And would not sell. But GM found a way to use there parts on Sonic as well as Cruze.
Sonic was designed in South Korea. The car is sold abroad as the Aveo.
Aveo had such a bad name here in the US they had to change the name to Sonic. On my Sonic shocks and struts are made by Daewoo, and an array of other parts
GM advertises first subcompact made in USA it should say assembled. ironic how all this information comes out after the car is bought.
