![]() ![]() Software gets increasingly more sophisticated and longer, which may make vehicles soon need more memory space. Considering how fast computers and software evolve, that is almost impossible.Īnything carmakers put inside a vehicle will become obsolete in a matter of five years, if not even less. Now, remember what NHTSA said about the MCUv1: the computer hardware has to last as much as the car. Everyone going electric is talking about similar services as a new revenue stream. Volkswagen created CARIAD to offer OTA updates and digital subscriptions. Hyundai said today it wants all its cars to be Software-Defined Vehicles (SDV). Think about all the carmakers that want their cars to be digital and follow what Tesla proposed before them. Before that, it charged up to $4,000 for the entire computer from those out of warranty. When Tesla was officially in charge of paying to fix the defective computers, it found a way to replace only the Visual Compute Module (VCM) daughterboard where the eMMC flash memory card is installed. NHTSA did not buy that story and said the computer should last as much as the entire car. ![]() Al Prescott, Tesla’s vice president of legal affairs at the time, tried to frame the MCUv1 as wear parts, which would make replacing them as necessary as changing the wiper blades or brake pads. Several Model S and Model X owners had to replace more than one computer until the National Highway Traffic Safety Administration (NHTSA) said the computer failure was a safety issue and that Tesla had to replace them in a recall. Although that was possible, it was cheaper (for Tesla) to just get rid of the whole thing. After around four years, these cards failed, requiring the entire MCUv1 to be replaced because Tesla had not thought about servicing these components. If you have not followed this story, what happened was that Tesla put an 8-Gb eMMC flash memory card in these early computers. ![]() Most people had not paid attention when MCUv1s started to fail in the Model S and Model X. ![]()
