Mercedes-Benz Safety Defect for Certain GLC & EQE Models | Steering Coupling Risk
Mercedes-Benz AG (MBAG), the manufacturer of Mercedes-Benz vehicles, has identified a serious safety defect that affects certain 2023–2026 Mercedes-Benz GLC (254 platform) and EQE (295 platform) vehicles. The issue involves the steering coupling bolt, which may not have been torqued to production specifications during assembly.
If the steering coupling loosens from the steering rack, it could result in a loss of steering control, dramatically increasing the risk of a crash.

Safety Risk to Mercedes Benz Drivers
The connection between the steering coupling and steering rack may loosen over time due to an improperly torqued bolt. If the coupling separates, the driver could experience a total loss of steering control. This dramatically increases the risk of:- Vehicle crashes
- Injury or death to vehicle occupants and others on the road
- Potential property damage in the event of a collision
Cause of the Safety Defect
The issue was traced back to a production deviation. Investigators discovered that the bolt securing the steering coupling might not have been torqued correctly. This gap in the assembly process created the possibility for vehicles to be released from the production line with an unsecured steering bolt.
In mid-July 2025, MBAG initiated an internal investigation after receiving a report of unusual steering noises. Further checks confirmed that the steering coupling bolt was improperly secured. In early August, MBAG reviewed production histories and identified affected vehicles.
By August 13, 2025, Mercedes-Benz determined that a safety risk could not be ruled out.
What Owners Should KnowM
- Dealer remedy: Mercedes-Benz dealers will inspect the steering coupling bolt and tighten it to the correct specification if necessary.
- Owner notifications: Letters are expected to be mailed starting October 17, 2025.
- NHTSA campaign number: 25V-533
- Reported cases: MBAG is currently aware of one U.S. warranty claim, received on August 26, 2024.
What This Means for Mercedes-Benz Drivers
If you own one of the affected GLC or EQE models, it is crucial to take this safety defect seriously. A loose steering coupling can compromise your ability to control your vehicle, putting you, your passengers, and others at risk.
Mercedes-Benz encourages all affected owners to schedule an inspection with their local dealer as soon as they receive official notice.
Final Thoughts
The 2023–2026 Mercedes-Benz GLC and EQE safety defect underscores the importance of addressing even small deviations in production. While MBAG has taken swift steps to correct the issue, affected owners should remain proactive and ensure their vehicle is inspected.
