My wife purchased a 1999 cadillac eldorado in 2009 and it only had 38k miles on it. Now in 2016 it only has 103k miles on it but while driving the engine coolant temperature gauge will frequently go from 'normal' to 'engine hot - A/C off'. After shuting off the engine, letting it cool, and topping off the coolant level, the will operate in the 'normal' temperature range for several miles but then it will suddenly jump up to the 'engine hot - A/C off' range. The car is now at a repair shop and they have diagnosed that this 1999 cadillac eldorado has failing cylinder head gaskets. Recall - campaign #99086 (march 19, 2002) acknowledges this defect and the reasons for it. Will cadillac please help us with this problem? A 103,000 mile cadillac eldorado should not have this issue and, if it does, the manufacturer should take responsibility.
