Common Issues And Challenges With Remote Starting A Mercedes-Benz

Many Mercedes-Benz owners have shared different experiences when trying to use this feature. While remote start is a fantastic feature, 65% of new car owners report issues, particularly in winter months. Here are some common problems and their solutions:

1.Key Fob Not Responding

Problem: Some Mercedes-Benz owners have reported that their key fob does not activate the remote start function. The vehicle doesn’t respond, or the key fob only locks/unlocks the doors but doesn’t start the engine.

Solution:

  • Check the Battery: A common culprit is a weak or dead key fob battery. Ensure the battery in your key fob is fresh. If it’s low, replace it and try again.
  • Verify Compatibility: Ensure your model has the remote start function. Older models or some trims may lack this feature.
  • Proximity to Vehicle: Ensure that you are within range. The signal from the key fob may not reach the vehicle if you’re too far away.

2.Vehicle Doesn’t Start After Multiple Attempts

Problem: Some users report that even after pressing the correct buttons in the right sequence, the car doesn’t start.

Solution:

  • Ensure Proper Mode: Check that the vehicle is in Park mode and has no open doors or trunks. The system requires the car to be completely secured before it will start remotely.
  • Confirm with Dealership: If the system doesn’t work after a few attempts, consult your Mercedes-Benz dealership. There may be an issue with your vehicle’s electronics or the remote start system itself.

3.Engine Shuts Off Too Quickly

Problem: The engine starts but shuts off after just a few minutes, even when no one is in the car.

Solution:

  • Check for Faulty Sensors: Some vehicles may shut off remotely due to faulty sensors in the car (e.g., if the door or hood is not properly closed).
  • Modify Settings: In some cases, the car’s settings can be adjusted by a dealership to extend the remote start duration. Ask your dealership if this is a possibility for your model.

4.Cold Weather Issues

Problem: In extremely cold weather, the remote start might not work or the vehicle may fail to start due to battery issues.

Solution:

  • Ensure Battery Health: Cold temperatures can affect battery performance. A weak battery may not support remote start.
  • Use the Mercedes Me App: If you have the Mercedes Me app, you can start your car remotely using the app. This may work better than the key fob in some situations.

Troubleshooting Remote Start Issues

  • 3 flashes – Normal shutdown
  • 5 flashes – Too many remote starts (reset required)
  • 6 flashes – Brake pedal was pressed
  • 7 flashesHood is open
  • 8 flashes – Engine RPM too high
  • 9 flashes – Engine failed to start
  • 10 flashes – Communication error

If remote start stops working, try this quick reset:

  1. Turn off the ignition.
  2. Lock the car with the key fob.
  3. Wait 5 minutes.
  4. Unlock the car.
