problem #5

  • Automatic transmission
  • 15,000 miles


Car inherited from step-father in Dec 2005 with less than 5000 miles on it. Treated like a baby with every checkup done by local dealership and never driven but locally in Phoenix. Garage housed the entire time before inheritance. Wife drove car less than 1000 miles per year until she recently passed. All work done by dealership and never had a problem except a dead battery replacement. I started the car recently for a trip to the local grocery store and as I was backing out of the garage, I heard a loud thump/clank noise and the engine quit. I got out of the car and noticed oil draining all over the garage floor. Vehicle towed to a local mechanic shop where they have pulled the engine for replacement. Spoke to him today and told me that in addition to the hole they initially found when the vehicle arrived at the shop, there is a silver-dollar sized hole in the top of the engine. He suspected a thrown rod before finding the second significant sized hole. He now thinks that the engine may have thrown a rod and piston. Pretty piss poor for an engine that has been babied for 14 years and only has 15,000 total miles on it. Where can I join a lawsuit on this.

DeVille 4.6L Northstar

  • Automatic transmission
  • 70,000 miles

First I had an oil leak at around 50,000 miles but i don't have ext warranty. then right before 70000 miles i notice white smoke, so i take it in to my friends shop (he used to work for cadillac) and he tells me i have a blown head gasket but its not worth fixing because its a common problem with this motor and its the head bolt pulling away or something. This sounds pretty lame. does anyone have a similar problem or any recommendations for me?

DeVille DTS V8

  • Automatic transmission
  • 96,000 miles

I have a 2002 Cadillac DTS and it has 96,000 miles. One owner, and I always took it in every 15,000 for a tune-up and changed the oil every 3k. A few days ago, the engine starting making a terrible noise and quit on me. Today, the caddy dealership called me saying the engine needs replaced....at 96,000 miles!!! Are you kidding me?

Does anyone have any recommendations? Thanks
