The Cadillac CT6 is an advanced and lightweight flagship sedan, but its fusion of aluminum, steel and carbonfiber makes it very difficult to repair.
The CT6 has a patented body made from aluminum welded to steel. That makes it light and unique, but also very difficult to repair if it’s involved in an accident.
To fix the CT6 to GM guidelines, shops have to have bespoke equipment, training, and certification. Only 150 places across the US have been certified, and 25 US states don’t have a shop that can fix the CT6.
With only 7,876 CT6 sedans sold so far in 2016, that may not be a problem too many have to worry about.
