I have a 2013 Chevy Cruze also and very bad vibration in her while driving and also in park. I took her to the dealership and they don't know what is causing it. Waiting on a vibration test to be done (a month now waiting) so in the mean time I took her to another garage and again unable to determine the cause. No check engine light on, RPM is steady, no leaks of any sort, checked spark plugs all good, did a compression test on her, turned out perfect. Mechanics are stumped as to what is wrong. Any ideas?? All and any help would be appreciated.
