2007 lucerne cxl rides like it has no suspension
How many miles on the vehicle? if over 100K, your looking at replacing the struts and shocks and or more.
the rearend bottoms out it does not bounce, it has never given any messages,the car has 200k it started acting this way suddenly, I was wondering about an easy way to check the compressor.
Something sounds broken, possible spring or sway bar bushing, blown shock, etc. At 200K, anything is possible. Have a mechanic get it on a lift to inspect.
