“The drivers side headlight shuts off and on or flickers - most noticeable during night time driving. Our dealer, ed shults chevrolet, advised us that this particular model of the Cadillac cts was not under recall.

“I bought a used 2006 DTS Cadillac from a dealer in oh. Brought it home and had my mechanic go thru it. He showed me an oil leak and said the oil pan gasket had been repaired. My mechanic said he would not fix the leak because there was too much involved. I have since seen that this a common problem with this year vehicle. Should be a recall. I can not afford to get this fixed. Also found out there were 4 other recalls on this car. Cadillac should have a recall for this oil leak. Mileage is 81,000”

NHTSA complaint #10496661, filed 2013-02, 80,000 miles

“We have owned this Cadillac since feb 2010 (approx 28 months) and have had this vehicle back to the dealer 16 times. Each repair requires a rental vehicle, anywhere from 2-5 days per service visit. We have had 7 wheel bearings replaced and 12 sensors replaced. There doesn't seem to be a day when the service engine light is not on. The quality of this $52,000 automobile is very poor. The vehicle is back at the Cadillac dealer now, with coolant & engine issues once again.”
