Wiring problems of the 1999 Dodge Intrepid

My wife was driving back from the store when the engine just stop and locked up right in the middle of the highway, she was able to coast the car of the side of the road. We had a mechanic look at it, the reason for the failure was the engine ran out of oil. The oil light never came on, not once, the mechanic could not find out where it went to, but couldn't. I had this car for about 11 months before this and checked the oil on a weekly basis. How could this happen. How could a Dodge dealer sell this car. Now I'm stuck with an $11,000 paper weight in my drive way. I think Dodge should replace my engine and figure out why something went wrong.

1999 Dodge Intrepid 2. 7 VIN#2b3hd46r7xh743055, 43,913 miles, transmission sensor went out, $132. 84. 9/14/00 75,085 miles, water outlet and transmission lines needed replaced. Mechanic informed me the transmission lines were factory installed defective. $582. 24. 12/14/01 86,992 miles, timing chain broke, replaced water pump. $1,188. 79. 6/14/02. 91,324 miles, transmission speed sensor broke. $350. 60. 8/2/02 96,828 miles, dash lights went out. Mechanic informed me the dash lights were an internal wiring defect. $223. 30. 10/2/02 98,003 miles, cooling fan went out. Mechanic informed me this was a factory defect. Chrysler had changed the design of the fans so I could not just repair one side of the fan since it was no longer available. $680. 35. 10/24/02. 109,754 miles, engine blew, taking starter with it. Told by mechanic that Chrysler designed the 2. 7 engine to be a disposable engine (compared to the 3. 2 that year). Replaced with used engine. $4174. 49. 5/21/03 I had over $7000 in repairs in under a year and a half. While Im gravely disappointed in the mechanics of this vehicle, I feel that the fan assembly, transmission lines, and electrical wiring are things that were obviously defective from the start and should be repaired free of charge. Additionally, the transmission sensor going out at only 43,913 miles should have been replaced free as well. While it is difficult to prove that I took care of the engine, I have oil change receipts.

While driving there was a burning rubber smell. Driver pulled vehicle on the shoulder and cut ignition off. Right afterwards smoke came from under the hood, and under the dash broad. There was a fire, in which the vehicle was totalled. Fire was put out by the fire department. Please provide any further information.
