I have this problem in my 2010 Buick enclave. Did anyone ever find a resolution?Sorry for reopening a dead thread. I have been experiencing the same exact issue. My vehicle is not a Civic, but is FWD. As an engineer this has really stumped me. Nearly all suspension parts are new as are Strut assemblies. Just started this summer after car washes. Lasts a few hours , goes away. Wondering if anyone solved this problem?
