First off, sometimes my vehicle when in park acts like it may turn off, but doesn't. can hear/feel the vibrations like its about to. secondly, the main reason i'm on this page, the a/c. it just stopped working out of the blue and making a noise. i take it in and told the condenser has a leak and needs replaced as well as the condenser which is making the noise. wow, quoted from one place $1,084 the other place i only got a quote on the condenser of $424.. no telling what the compressor will be. after looking online and seeing so many equinox vehicles having ac issues i hoped there was a recall on the parts, unfortunately not the case. 2011 and need a new condenser and compressor for a/c wow!! car shaking like its gonna die... wow!! this vehicle was purchased about a year and half ago.. and having to sink in over $1000 for these replacements! no telling what the engine vibration during idle is from, going to have that checked out soon. oh and one other thing, when a tire is low, it appears to shows up backwards on the screen. *tr
