There is no other way to say it except to say GM lied about the mpg.
The only time i ever achieved 32 mpg was driving 45 mph, by myself with no AC.
And i drive like a grandma.
The transmission is not at all smooth, and at times when shifting vibrated the entire car.
Just listen to one idling in the parking lot with the AC on.
It sounds terrible.
I took a huge loss and dumped this car after 14,000 miles.
I am amazed that GM was able to get away with advertising 22/32 mpg.
I am not a big conspiracy theorist, but on this one, i don't have any other explanation.
I have owned more than 15 cars.
This is the first one i have ever owned where i couldn't get anywhere near the advertised mpg
