This is the nicest car I have ever owned . We bought it for a road car .
First thing I did , after I got it home ( dealer had changed oil / filter ) was to do some internet research . Discovered the plastic coolant elbow issue . What idiot engineer dreamed that up ?
I replaced them with metal elbows , although , luckily , mine still looked OK .
I bought new heater hoses , radiator hoses , serpentine belt , Tstat & gasket , engine air & cabin air filters as preventive maintenance . Installed all myself , although the rubber products still looked OK .
At my age , last thing I need is to have a coolant leak on the highway , miles from home & my tools .
My wife drives a 2015 Chevy Sonic & I drive a company truck , 2007 Silverado . So , the Buick does not get driven but , maybe once a week . That will change when I fully retired . I presently work 1/2 days ( normally ) .
So far , I am very happy with the Buick . Getting about 19 MPG in town and 27 - 29 MPG highway .
