The instrument panel stopped operating, different mechanics could not locate problem, cadillac deal wanted 200.00 just to review. several owners of same mocel having same problem. dealears refuse to correct or even look at the cause without customers paying for service call. this seems to be a common problem with this car, as others having same problem. i have been told it's faulty electrical cluster in instrument panel and car is now out of warrenty, but was withing warranty at time of occurance, i failed to take to dealer in timely manner. can anything be do ne about this. i now have 87,000 miles on car. *tr
