Germany's Equivalent To NHTSA Has Tesla MCUv1 Under Scrutiny Too ++ Will KBA follow NHTSA and demand a recall for the component? NHTSA asked Tesla to recall 158,000 cars that use the MCUv1 in the US. Yet, about 159,000 Model S and Model X units received the computer. The difference refers to EVs sold abroad. At least one safety watchdog abroad took what NHTSA said seriously and is also investigating the MCUv1: Germany’s KBA, or Kraftfahrt-Bundesamt. According to Bild am Sonntag, Germany’s Federal Motor Transport Authority would be in contact with NHTSA and would also have asked Tesla for similar documentation and data to determine if the issue these computers present will demand a recall in Germany or not.
