S10 appropriate handling- letter to the secretary from constituent re copy of a letter addressed to General Motors chief executive officer mary barra regarding the recall of vehicles that can leak oil and catch fire. The consumer stated the technician showed him where burnt oil had leaked through engine gaskets between the crankcase and manifold. The consumer was quoted a price of $ $4,153 for the replacement of the gaskets. The price went up, after the repairs were in progress. The consumer was informed additional gaskets were needed.

There was no previous indicator of a trouble condition--first indication of trouble was mis-firing---long story short---a complete engine over haul (rings, bearings etc.) was made aware that these cars normally use 1 qt oil per 2000 miles---there is no warning for low oil level on the dash or dic other than remaining oil life, which was ok--an extended warranty covered the repairs the car had between 68K-69K miles and had been maintained as required by the dealership----

problem #2

The car has had several documented electrical and mechanical failures. Over the past 2 years the car has been shutting down automatically in the middle of traffic. The display shows ¿engine power reduced¿ and is followed by other messages like 'service anti-lock brake sys¿ or 'service radar¿ or service stability sys and traction control.¿ before the car shuts down the traction control is automatically disabled. I have had to bring the car in for the same symptom 4 different times. The in-service dates that were described and documented for this problem are as follows: 1.)February 22, 2008 ¿ ¿poor drag on C102 connector under hood¿ 2.)April 24, 2009 ¿ ¿failed converter¿ 3.)October 1, 2009 ¿ ¿ECM failed¿ 4.)May 5, 2010 ¿ ¿reprogram PCM¿ all of the above were serviced by classic Cadillac Saab. Each time they fix something new but the same symptom continues to occur. I am extremely concerned for my family's safety when traveling in the car, especially when it has shutdown numerous times both on a highway and in the middle of an intersection. The car has become a severe liability for both me and my family. Sometime in December 2010 the car had shutdown again and the engine light has been on and off since then.
