How Do the Transmission Issues Affect Mercedes-Benz Vehicle Safety and Performance?

The main safety concern is that the transmission software defect can cause the engine to stall without warning. This stalling happens due to a failure in completing the downshift from 7th to 6th gear under certain conditions.

Signs and Symptoms of the Transmission Problem

  1. Loss of Power: The most noticeable sign is a sudden loss of engine power. The vehicle may slow down abruptly, and the engine will no longer respond to the accelerator pedal.
  2. Warning Lights: Dashboard warning lights, such as the check engine light or battery light, may illuminate when the engine stalls.
  3. Difficulty Restarting: After stalling, the engine may be difficult to restart. It might crank without starting or require several attempts to get running again.
  4. Noises: You might hear unusual noises before the stall, such as sputtering, coughing, or knocking sounds from the engine.
  5. Jerkiness: The vehicle may jerk or shudder just before the engine stalls, indicating a disruption in the engine’s operation.

Engine Stalling

When the engine stalls, the vehicle loses propulsion, though steering and braking systems remain functional. This loss of power can pose a significant risk, especially at high speeds or in heavy traffic.

If you’ve experienced these common transmission problems and signs, your car may be at risk of power loss while driving. You can identify when this is happening and be aware when you notice the following:

  • Speedometer and Tachometer Drop: The speedometer may show a rapid decrease in speed, and the tachometer (which measures engine RPM) will drop to zero.
  • Lights on Dashboard: Various warning lights may illuminate on the dashboard.
  • Motion of the Vehicle: The vehicle will come to a halt if it is not moving, or it will coast if it is moving. The driver may have to steer the car to a safe location to restart the engine.

Example Scenario

Imagine driving on a highway when suddenly your car begins to lose speed despite pressing the accelerator. You notice the engine sounds different, making sputtering noises. The check engine light comes on, and then the engine stops completely. Your car slows down, and you carefully steer it to the side of the road. After stopping, you try to restart the engine, but it cranks without catching immediately. This is an example of an engine stalling.

Given the 100% estimated defect rate, this issue is particularly significant as it affects every single unit of the affected models. The potential for an engine stall in all these vehicles represents a substantial risk to driver and passenger safety.

What Should Owners of Recalled Mercedes-Benz GLE 450 and GLS 450 Do Next?

Owners of the affected vehicles will receive notification letters from Mercedes-Benz. Here are the steps they should follow:

  1. Contact Mercedes-Benz Customer Service: Owners can call 1-800-367-6372 for more information.
  2. Schedule a Service Appointment: Authorized Mercedes-Benz dealers will update the transmission control unit software free of charge.
  3. Check for Updates: Owners can visit the NHTSA website or the Mercedes-Benz recall website for the latest information on the recall.

Conclusion

The Mercedes-Benz GLE 450 and GLS 450 software recall is a crucial step to ensure the safety and reliability of these vehicles by fixing the transmission issue. Owners are encouraged to act promptly and follow the outlined steps to have the necessary software updates installed.
