A recall does not mean your car is affected. Check the market, build date and VIN with the manufacturer.
- Engine / equipment
- Active Curve System (ACS) oil reservoir: Mercedes-Benz GL / GLS (X166) fitted with it
- Period mentioned
- Model years 2013–2017 in the US (only the VINs in the recall)
- Symptoms
- The official record describes no early warning signs. If the oil level in the ACS reservoir is below the minimum, in certain driving conditions the oil may foam and leak out of the vent holes in the cap.
- Possible cause described
- With the oil level in the Active Curve System reservoir below the minimum, the oil may foam and leak out of the vent holes in the cap; if it reaches an ignition source, the risk of fire increases. It is US recall 18V272 (Mercedes-Benz 2018070015, 9,725 vehicles across GL, GLS, ML and GLE models with ACS); the remedy is to correct the oil level and replace the reservoir sealing cap.
- Check for the garage
- If your GL or GLS has the Active Curve System suspension, ask a Mercedes-Benz dealer, with the VIN, whether this recall or a European equivalent is outstanding: they correct the oil level and replace the cap free of charge. If you see oil or foam in the engine bay, or smell burning, do not drive on.
- Cost cited in the source
