Electrical or software fault may disable vehicle functions
An error in the communication module's SIM card software can cause a mobile network connection failure, disabling the emergency call (eCall) system.
What the reviewed source says
Start with the documented condition, not a parts guess.
NHTSA campaign 22V365000 includes certain 2017 to 2022 Mercedes-Benz GLS 450 vehicles. Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2017-2022 CLA-Class, GLA-Class, GLE-Class, GLS-Class, SLC-Class, A-Class, AMG GT-Class, C-Class, E-Class, S-Class, SL-Class, GLC-Class, CLS-Class, GLB-Class, and G-Class vehicles. Please refer to MBUSA's recall report for specific vehicle model details. A disabled eCall system would prevent a vehicle occupant from contacting the emergency services call center in an emergency, potentially delaying emergency responders and increasing the risk of injury.

Check the complete VIN before arranging work
Enter the 17-character VIN in NHTSA's recall lookup and ask the manufacturer or an authorised dealer to confirm whether the campaign is open for this vehicle.
A year, make and model match does not prove that every vehicle is included. The VIN result controls eligibility.

Useful before authorizing work
Read the method beside the problem
These guides explain the safety and evidence checks that apply to this problem file.
Check recalls by VIN
A VIN search checks the displayed NHTSA records for an unrepaired safety recall associated with one vehicle. A model search shows only the wider campaign population.
Read guide ↗When a car is unsafe
A warning light does not always mean the same thing, but weak brakes or smoke leave little room for experimentation. Damaged tires and certain recall instructions can do the same.
Read guide ↗Why symptoms overlap
“It makes a weird noise” is useful human language. Diagnosis begins when that language is tied to the exact vehicle and its operating conditions.
