Open the full vehicle complaint log (all categories)I brought my car in for routine service and was told I needed a rear main seal. I had the car inspected when I purchased it appx 13k miles ago because I saw online there was a lot of people having this issue with their vehicles. It’s a known manufacturer defect. At that time there was no issue. Now at 40k miles it began to leak. This is round about the mileage most people have experienced this issue. A car with 40k miles shouldn’t have a defect like this that could cause the vehicles oil to leak out the seal and destroy the motor. I believe MBUSA should be replacing all of these seals on all of the affected vehicles. A consumer shouldnt be charged $6500 at 40k miles to repair a seal that is failing on so many vehicles.
