“My oil cooler has been leaking since 41,000 miles and I have read other mercedes benz S600 owners have the same problems. To fix this problem I would have to pay a shop 4k dollars. If this is a common problem for this car I think mercedes benz should have a recall on this issue and fix the problem. I leak up to a quart of oil every 2 weeks.”
NHTSA complaint #10291912, filed 2009-11, 44,000 miles“Car only has 64k miles and has a bad oil leak. My guess is the oil cooler. For the price of this car I should not have a puddle of oil on my garage floor.”
NHTSA complaint #10239112, filed 2008-08, 63,700 miles“The mercedes benz dealer informed me that I had an oil cooler and abc hose leak on my 2001 S600. The cost to repair is unbelievable. About $7,500. In reading the mbz forum this appears to be a common occurrence without any help from mbz. The failure for the oil cooler leak can lead to a fire, and the abc hose leak can lead to malfunction of the active body control system causing the car to drastically lower at the effected wheel. The frequency of this problem should be covered by a manufacturer recall. This is a death hazard to me and my family. …”
NHTSA complaint #10239498, filed 2008-08, 76,568 miles“These S600 with v12 engines from 2000-2005 have severe engine oil cooler leaks. Some with as little as 30,000 miles. These vehicles should have been recalled years ago now mercedes wants to charge from 5,ooo to 6,000 to repair this problem and dont want to warrant after fix because its a recurring problem because of poor engineering. Their should be a recall on this problem.”
NHTSA complaint #10838369, filed 2016-02, 80,000 miles“I have a 2001 mercedes benz S600. The vehicle only has 76,000 miles. The engine oil cooler is leaking, and this can cause a fire. There is a lot of other people who have the same problem with this make and model. It seems to be a manufacture default. The leaking oil can run on the catalytic converter and cause a serious fire. Mba should have a recall on this problem.”
