“After driven the new 2006 ml350 for 3500 miles, the low engine oil indicator come up. Took the car to service, and found the car is leaking engine oil in multiple places. It took 1 week to fix the leak between transmission and engine. Then they need to order parts to fix second leak in oil pan. After the part arrived, I took the car to be fixed. After 3 days without any call, I called to find out the status. Now, they said one of the engine cylinder is leaking engine oil and need several more days to fix. …”
NHTSA complaint #10144352, filed 2005-12, 3,500 miles“Suv engine stalled 7/3/2005 going 65 MPH without warning; SUV restarted after stall. Suv engine stalled again 7/22/2005 going 45 MPH without warning; SUV did not restart after stall. Towed to dealer. The dealer found nothing wrong with vehicle and said cause was water that spilled during the incident however water spilled because of incident not before. Suv had stalled 3 weeks prior and no water was involved. I am scared to drive this vehicle for fear it will stall and I will get hit from behind causing bodily injury or death. Please help if you can. Thank you.”
