1. No warning. 2. Excessive oil consumption. Cadillac is aware of this issue and needs to issue a recall before one of their engines uses all the oil, over heats, causing a fire that kills someone. This issue is all over TSB forums 3. Beyond adding 5qts of oil between scheduled oil changes nothing. I cannot afford the $5000 engine rebuild for their mistake.
The contact stated the vehicle burned oil excessively. He had to add a quart of oil every 750 miles. Took the vehicle to the dealership multiple times. The dealership replaced the piston rings on April 4, 2005. After the piston ring replacement there was a reduction in oil consumption. T two service bulletins 1358091 and 1396266.
