Wiring problems of the 2006 Cadillac DTS

The contact owns a 2006 Cadillac Dts. While driving various speeds, the headlights failed to illuminate. The contact had to reset the light switch by flipping the switch back and forth for the lights to illuminate. The failure recurred each time the vehicle was driven at night. The vehicle was taken to an independent mechanic who diagnosed that a bulb or wire caused the headlights to fail. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 70,000.

While driving the vehicle down the road with the heated seat (drivers side) on, I began to notice a burning smell and smoke coming from the passenger seat area. Stopped the vehicle to inspect to find a smoldering wiring harness and module, there was a small flame. The flame was extinguished. The vehicle was then turned off and brought to a gm dealership that diagnosed it as having a bad connector. Dealership also stated that this is a common issue on these cars. In order to fix this and make it safe it required the module under the passenger seat and the connector to be replaced. Was informed that the new module is an improved design that shouldn't have the same issue. All service was performed and the vehicle and accessories is now functioning as they should.

Shortly after purchasing my Dts I began to notice a melting plastic/smoke smell whenever I would turn on the driver's side heated/ventilated seat heater. I took the car to the dealership and was advised this is a common wiring problem on the Buick and Cadillac models and that I should stop using the heated seat function because the wiring is undersized and can melt and burn. The dealership told me the new part has been revised to include larger wiring but the part has not been recalled at this time so there was nothing they could do for me.
