Report: Front and Rear Light Bulbs may Fail
Cadillac CTS Problem
Average Mileage: 77,500 mi (50,000 mi - 125,000 mi)
The front and rear light bulbs are prone to premature failure. Our technicians tell us that the front bulbs can be very difficult to replace.
Had to replace mine. I went to a auto parts store and bought mine, and had them replaced for about $400-$500 for both. At the dealer one headlight bulb is $500 each. To replace them the front bumper has to come off no other way to get to the front headlights.

Driver's side rear light melted into light socket. Picked up a replacement at AutoZone for $34. Now passenger turn signal light has gone out. The top of each head light cover is discolored, it looks like a heat related effect on the top of each sealed plastic cover.
