Heated and cooled seats stopped working while driving after burning smell and smoke that was coming from under passenger seat.

- Salem, NH, USA

As part of state inspection, told dealer that front seats are not heating. Told by dealer that problem was "connector to climate control seat module burned/shorted out module" and to replace connector and module would cost $1016. Asked dealer personnel if a safety issue and they said it is a routine/recurring problem with these components melting from the heat but don't worry it's not a safety issue (despite reference to " burned/shorted out"). internet search showed similar problem with same components in other Cadillac but accompanied by/with smoke and/or fire-- if occurs while operating vehicle at a high speed on a busy street or highway, could result in a major accident involving serious injury or death. Needs to be investigated.

In regards to: Heated / cooled seat inoperative - keywords climate control cool cooled driver front heat heated inoperative intermittent left module passenger right - (Mar 18, 2008) subject:heated/ cooled seat inoperative models:2006- 2008 Buick lucerne w/ RPO KB6 2006- 2008 Cadillac Dts w/ RPO KB6 I had my heated/cooled seat module replaced in August 2013. Through the winter my heated seats worked fine. Today I turn on my seat heaters only to hear a clicking noise coming from under the passenger seat followed by puffs of white smoke. I quickly turned the car off and disconnected the battery. Upon visual inspection of the area where the smoke came from. I found the module melted to the connector so much so I had to remove the relay for the seat module. This fire could have grown dangerous very quickly. I know a number of fellow Cadillac/Buick owners that this has happened to. If GM does not resolve this issue with a recall there will likely be legal action taken.
