My back center brake light no longer works and since this was pointed out to me earlier this month, I have noticed at least four other Cts cars with the same issue. They range from my year ('06) to at least 2009. And when quoted a price ($600+!) I balked at having it replaced. Anyone else notice this or have this issue?

There should be a recall on all Cadillac Cts models 03-07 for faulty tail lights. The long center stop light is neon and moisture burns it out, difficult and expensive to replace, faulty product-some states require this third stop light, dealer wants $700+ to replace with new faulty part. The two regular stop lights are equally difficult to fix when they stop working. No brake lights on this vehicle. To check the fuses is additionally complicated as one or both are under the backseat which requires removal of the seat, including two other fuse situations. This is truly dangerous and the design and product is inferior, taking much time and cost to have repaired. I am not aware of any other vehicles at these model years with un-safe difficult brake light issues, and Cadillac is arrogant to say "it's a Cadillac thing" I think Cadillac needs to get it's lighting functions correct for road safety issues and I'm so angry about this problem that I think Cadillac should be forced to re-call these vehicles and fix them properly at no charge with properly functioning lighting electrics and bulbs. Mal-functioning brake light problems are in my opinion a grave safety issue.

Automatic light sensor does not sense daylight for 5 mins and 23 secs at the last timing. In a daylight drive of 12 miles, the car turned night-time lamps on and off 6 times. Dealer says it is working as designed. This has just started to happen the last 12 days. No light settings have been changed since they were set when I purchased the car. I was told by sholz Cadillac repair to wait for the lights to sense the change before driving. However, what do I do when entering and exiting a tunnel? when placed side by side with a GMC xuv with an automatic sensor, the GMC senses the difference in light in 3 seconds. This delay in my Cadillac is certainly a safety hazard.
