2008 Cadillac BLS

The 2008 Cadillac BLS, primarily sold in Europe, was Cadillac’s attempt to enter the compact executive car market. It was available as a sedan and wagon (estate) and offered a range of engines including gasoline and diesel options. While not sold in the United States, it’s important to address the common issues reported by owners in the markets where it was available. Specific engines included various turbocharged 2.0L gasoline engines, a 2.8L V6, and a 1.9L turbodiesel. Transmissions included manual and automatic options. Owners appreciated the BLS’s distinctive Cadillac styling and comfortable interior, but common complaints revolved around reliability issues, particularly with the diesel engines and some electrical components.
