Mercedes-Benz is recalling 4,871 2014-2015 GLK250, ML250, and E250 BlueTec vehicles because oil can leak around the chain tensioner gasket area.

What's wrong?
The chain tensioner helps keep the diesel engine's timing chain tight so the crankshaft and camshafts stay in step. The gasket around that tensioner seals the joint where it fits into the engine block, keeping engine oil inside the engine.
On recalled 2014-2015 Mercedes-Benz GLK250, ML250, and E250 BlueTec vehicles, the gasket material was made with tolerance variations during a specific production period. If the gasket does not seal correctly, oil leaks from the chain tensioner area. Oil loss at that point can leave oil on the road surface, and the engine can stall as a result of the defect.
The warning sign is engine oil leaking onto the road or under the vehicle. If that leak is present, the engine stall risk described in NHTSA campaign 14V762 is tied to the same gasket problem.

What's the safety risk?
Engine oil leaking onto hot engine surfaces raises the risk of fire. Oil on the roadway also creates a hazard for other vehicles and raises crash risk. Watch for visible oil leakage and treat it as a reason to schedule service soon. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2014-2015 Mercedes-Benz GLK250, ML250, or E250 is included in this recall.
- Contact a franchised Mercedes-Benz dealer to schedule the free chain-tensioner-gasket replacement that addresses oil leaking onto hot engine surfaces.
- Bring the recall notice if Mercedes-Benz mailed one. If not, reference recall number 14V762 when you call.
- Avoid driving if you see oil leaking before the repair, and keep the vehicle away from hot engine surfaces until the dealer inspects it.
- Call Mercedes-Benz customer service at 1-800-367-6372 with questions about scheduling or owner support.
What happens at the repair
At the dealer, a Mercedes-Benz technician replaces the chain tensioner gasket to address oil leaking from the chain tensioner gasket area. The recall repair is available now, and parts and labor are free. Out-of-pocket repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, because the involved vehicles remain covered under that warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
