Mercedes Benz said the problem could mean emergency services are not given the “correct current position” of the vehicle. The eCall system is designed to automatically alert emergency services when the car crashes and relays location information directly to them.
“During this product monitoring, Mercedes-Benz has found that in certain vehicles of various model series, the communication module HERMES for the emergency call system (eCall) does not comply with the specifications.
“In rare cases, this could mean that in the event of an accident-related temporary drop in a vehicle’s voltage, the communication module might not communicate the correct current position when an emergency call is made/triggered.
“All other functions of the automatic and manual emergency call function remain fully operational.
“Mercedes-Benz is therefore conducting a recall of the affected vehicles in order to update the software of the communication module HERMES.
The EU voted to introduce the eCall systems to all new cars from 2018 in a bid to cut emergency response times.
The technology can only provide basic data such as the type of vehicle, fuel used, time of accidents and location.
The device adds around £72 to the manufacturing costs of each new car but offers extra protection for drivers in the event of a heavy crash.
