I bought a Buick Lacrosse VIN [xxx] on March 30, 2006. I picked up the car on March 31, 2006, and had a problem with a low oil pressure light that day. I was sick after picking up the car but attempted to use onstar diagnostic which they were unable to pinpoint the problem and I E-mailed the dealer concerning the problem. Upon my recovery, I returned the car to the dealer for service on April 7, 2006. On April 10, 2006, the service department contacted and informed me that my car needs a repair to the camshaft assembly. This defect existed the day I picked up the car, it had 87 miles on it when I picked it up, and since the car was inspected the morning I picked it up, the dealer allowed a defective product to be sold and delivered. Upon contacting Buick to making Buick is aware that this had happened and seeking resolution the dealer put a new engine in the car. It is not appropriate for the dealer or Buick to sell a defective car and believe that putting a new engine in the car resolves the problem. I have complaint to Buick and the dealer about this numerous time but I get stone walled, they completely ignore the problem existing prior to me buying and taking delivery of the car. I have asked for a replacement vehicle, partial, or total refund and I'm ignored. All Buick does is offer oil changes and an extended warranty, which I find useless. Especially when the onstar module failed, April 22, 2006, and had to be replaced. Updated 07/16/2012 information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6)

The low oil pressure alarm rang after only 1542 miles dealer made appt for 2/21 - wasn't worried "probably only a false alarm". the alarm rang again at 1550 miles. I made the dealer take the car back to dealer. GM had to replace engine due to metal in oil pan. I've only made one payment and don't feel the car is worth a new car price.
