“Lower engine oil leak. I understand that this is a common problem dating back a number of years and Cadillac has not rectified the problem and has not issued a recall. I am forced to install a new engine because the problem is so costly to resolve. Approximately $4,500. Is there any class action against Cadillac or is there any relief available.”
NHTSA complaint #11111504, filed 2018-07, 90,000 miles“The car gives off false oil pressure information on cars message center. I replaced the sensor as discribed, verified my oil level, cleaned the connector to oil pressure sensor and still every 2 or 3 mintues I get engine oil pressure low, stop vehichle. When I stop the oil level is great and the oil is very clean. This has been going on for over 3 months. If the oil pressure was low the engine would have siezed up by now. This is ongoing issue with these 08 Cadillac DTS 4.7l northstar engines.”
