2006 Cadillac DTS

The 2006 model year initiates this federal record with significantly higher consumer complaints than subsequent years, registering 254 complaints compared to 97 in 2007 and declining steadily to just 15 by 2011. While recall counts remain relatively stable between 2 and 4 annually, the 2006 model is the only year in this dataset associated with an active federal investigation. Owner reports for 2006 focus primarily on Exterior Lighting with 54 complaints, followed by the Electrical System and Engine with 32 and 30 complaints respectively, though the data does not specify the root causes for these failures. Safety-related feedback includes 14 crash complaints and 10 fire complaints, marking a higher safety concern profile than later years where investigation counts drop to zero. Technical Service Bulletins rise from 724 in 2006 to 1153 in 2011, even as consumer complaints diminish over the generation. Given the peak complaint volume and unique investigation status relative to the improving trend in later years, the 2006 model represents a higher risk purchase compared to subsequent production years.
