Soon after buying a Cadillac DTS, serious electrical problems occurred. My wife was driving down the road and the car suffered a total electrical system failure - all lights inside and out, dash gauges, etc failed. Only the engine kept running. She drove straight to Covert Cadillac. They returned it the next day saying they could not duplicate the problem.
It happened three days later on the highway - very dangerous. We towed the car in. They kept it for a week and said they finally found a frayed wire. The next day the lights started flickering. They said they could not duplicate the problem. I found a General Motors service bulletin (#PIC4812) specifically addressing the lights flickering. Covert still said they could not duplicate the problem.
A total of 13 trips to the dealer for flickering lights, GPS failing, seat controls, dash gauges, unintended acceleration, yet the service tickets read "cannot duplicate customer concern at this time. [continued below]...
