I've owned this car from August of 2013 to January 2019(now). I became the second owner of her at 81,000 km.
For the first three years(2013,2014, and 2015), she had been running healthy. But she has not been healthy enough during the recent three-year-span. She has got the notorius front brake jobs done twice at 115,654 km in 2016 and at 125,133 km in 2017 because of warped rotors and uneven premature brake failure.
Last year, she has got the whole rusted fuel line and the both front lower arms changed.
In addition, she has been struggling with her weak auto transmission system especially during the harsh Canadian winter seasons.
I do not know whether this is common problem of HHRs or not. But this 2.2L Chevy banger is not reliable in the long run.
