Like a bad case of herpes - that night with that attractive someone later came back to haunt. Purchased a low miles (35K) 2007 3.6L sedan based partially on my local mechanic stating that the 3.6L engine was 'bullet proof.' I purchased from a Cadillac dealer (Val Ward in Ft Meyers FL) in 2012. It was an attractive car that rode extremely well with decent acceleration and very good handling and braking. Checked all the blocks by checking reviews, car fax, prepurchase check with independent mechanic. Within months I started having problems. First the ABS started going off (intermittently), making braking horrendous and dangerous. Then noticed the engine started eating oil. There was no (blue) smoke from the exhaust, but my mechanic suspected the emissions system (CAT, etc) was absorbing the oil leaking out prior to the bypass. [Note - I should have cut my losses and sold this thing at that point, but the wife loved the car & the Mech thought it wouldn't get any worse.] Later the check engine light came on. Code said it was a Cam sensor - which was replaced (not cheap). The light later came back. Here's where it gets bad -- in year 5 of ownership at 100,000 miles the engine essentially went. (All kinds of noises that was most likely timing chains / guides and perhaps other bad items from the crank case. Keep in mind this car was driven easy by a female and I believe the first owner was elderly.) Replacement REMAN engine is over $5K installed and rebuilding the existing engine with duel Cams is about the same. Trade in value without major problems is currently extremely low around $3,000 thanks to Cadillac flooding the market with these vehicles. My Mech (who sold his SRX with the same engine) said that Cadillac knew about these engine problems and has done nothing about it other than quietly fixing the problem in a later model year. He also believed fairly early that Val Ward knew there was a problem with this vehicle before selling it. Careful sleeping with this pretty babe.
