Engine Oil Leaking Problems of GMC Sierra

Truck is leaking oil, and I have a small puddle OH garage floor. Brought to original selling dealer to be checked. They claimed there was a plug on back of engine that was leaking. They had vehicle for 3 1/2 days, and claimed it was fixed. They had over 1 page of seals, gaskets, plug were replaced. Drove approximately 50 miles, and it started leaking exactly the same as before. Returned to dealer again, and was told by the service technician that it was normal to see it having a leak due to the silicone that was used on engine parts when it was built !!! I was advised to drive it for 1 week and bring it back again. At that point in time, I contacted gm and was told to get a second opinion at another dealership. I brought it to them on 11/15/13. It has been there now for 6 days. I was just told that they have 4 pages of new parts that have to be ordered to repair it. They (dealership) requested that gm replace the engine and was denied. Considering this is the 3rd time trying to repair the same problem, they should either re-purchase or lemon law this.

The contact owns a 2003 GMC Sierra. While driving less than 10 mph in a busy parking lot, the contact depressed the brake pedal before completing a left turn and felt the brakes shaking. The brake pedal extended to the floor. He was able to maneuver the vehicle to safety and continued to apply the brakes. He allowed the vehicle to coast until it came to a complete stop. The dealer stated that the failure occurred due to corrosion of the brake lines. The manufacturer would not assist with the repairs due to the corrosion. The failure and current mileages were 87,974. Updated 12/17/08. The rear main seal was leaking oil. The wheel speed sensor was replaced, due to the abs light illuminating. Updated 12/18/08.
