Headlights problems of the 2012 Cadillac CTS

While driving heard clanking under the car for about 2 blocks then stoped. Took it to the dealer and found out 2 bolts had backed out of the drive shaft and one had sheared. Had the exact same problem with a 2011 Cts. I had purchased a warranty when I bought the car in 2018, car was repaired. I did notify Cadillac. Right front headlight has moisture. Understand Cadillac used inferior seals previously. Will need to replace. Light cost approximately $250. 00.

Both headlights on the vehicle have had to be replaced very recently (spring/summer) following a cold and harsh winter. We believe that the problem identified with the srx models extends to the Cts and perhaps other Cadillac models given the number on the street with a single headlight; however, Cadillac has denied our claim. The cost of repair of both headlights exceeded $600.

My station wagon is a 2012 that I bought new in Aug 2013. In about a year I noticed condensation on the inside of the sealed led headlight assembly.
