- Buick Ownership
I bought my Encore Gx in May (1.4L awd, with Tech) and was impressed with the power, handling and mileage but I found the drive harsh (you could feel every bump!) which I assumed was because this was my first SUV after a series of sedans. The monthly ONSTAR reports always reported everything was fine. About four weeks ago I checked the tire pressures for the first time - they varied from 42 to 45 pound per square inch. I then checked with other gauges and the pressure was consistently high. My Onstar reports in kilopascals (which I did not translate) and only flags low pressure, NOT over-pressure. I adjusted all the pressures to 35 and the ride was much softer - but the handling was "loose" - like poor alignment or bad shocks. Last week I took the car in for service and asked for the front end to be checked, particularly at highway speeds. Of course nothing was found - could not duplicate the problem. After several years rally driving I know when the handling is not right. Any way I picked up the car from service and drove it home by way of the freeway - it clearly handled much better and felt "tighter". I do not know what they did but it feels much improved which even my wife noticed right away.
