A tale of low octane fuel, a grenaded Cadillac SRX and GM's response — Autoblog More details at http://www.automobilesdeluxe.tv/fol...th-gm-to-update-all-2010-cadillac-srx-turbos/. Interesting... I've already heard of possible engine damage due if you here continuous or severe knocking, but this is the first I've heard of anything where it was this bad. http://www.autoblog.com/2010/05/27/gm-recalling-select-2010-cadillac-srx-crossovers-over-engine-fai/ mentions there's a recall on this now. It looks like it took 2 months from discovery of the problem by LAU for the recall to be issued... hmmm. http://www-odi.nhtsa.dot.gov/recalls/recallresults.cfm?start=1&SearchType=DrillDown&type=VEHICLE&year=2010&make=CADILLAC&model=SRX&component_id=0&TYPENUM=1&SUBMIT=Retrieve%20Recalls&summary=true&prod_id=748773&PrintVersion=YES lists May 24th. edit: Hmm, from http://nhthqnwws112.odi.nhtsa.dot.g...s/Public/Recalls/2010/V/RCDNN-10V223-8930.pdf, they first hit this on December 12, 2009 and they assigned an engineer to look at it on March 10, 2010 w/the LAU incident.
