06 Cadillac Dts has had serious electrical/computer system failures since new. Vehicle will suddenly lose all electronics, instruments, lights but engine will still run. After dealer attempted repair, problems continue. Headlights flicker and sometimes go out. Gps goes to night screen during the day. Auto headlight dimmer fails. Power points, instruments, seats periodically fail. One day seat cooler will work, others it won't. windshield wipers automatic function, "rainsense" starts normally but then stops in heavy rain requiring manual operation. All items reported to dealer multiple times with the same result "unable to duplicate customer's problem." Provided cell phone video of system failures but dealer still says they cannot duplicate.

I have a 2006 caddillac Dts. There is an intermintent issue with the headlight and dashboard. They sometimes go into the nighttime mode in the daytime and it is very hard to see the dashboard when driving. I' searched google and found that other people have the same issue. GM told me they have no fix for this and it is not a big issue. Since they only have few complaints.they di D fix this in the 2007 model but they say even though it is the same model and body they cannot do anything. You also cannot use the flash yo pass headlight in the daytime.it only works in the night mode.
