NHTSA vraagt nu officieel een terugroepactie voor "het eMMC-probleem" bij de oudere Model S/X.
Het zou tot ~ 158.000 wagens betreffen.

Tesla heeft al eerder actie ondernomen en wagens hersteld, zelfs onder verlengde garantie. Blijkbaar is ook de oude MCU nog deel van het probleem, alleen de eMMC vervangen is dan onvoldoende.

Blijkbaar dringt NHTSA nu aan voor een terugroepactie, zodat de klanten niet zelf moeten aandringen enz..., voor een definitieve degelijke reparatie (sowieso betere chip en eventueel (de laatste) nieuwe MCU).

NHTSA is formally asking Tesla to recall over 100,000 Model S and Model X vehicles over a problem with its media unit (MCU) that can affect many functions inside the vehicles.

Tesla MCU/eMMC Problem

Owners of older Tesla Model S and Model X vehicles have been reporting some issues with their MCUs.

The touchscreen becomes less responsive, the power-up time becomes longer, the screen freezes and has to be rebooted, or there is even total failure of the MCU unit.

Some owners believe that it is a problem with the embedded Multi-Media-Card memory (eMMC) in the MCU and that it is being overwritten to the point of failure.

It has known as the “eMMC failure” problem.

Tesla introduced a new MCU in 2018 that doesn’t have the same problem, but owners of older vehicles are still experiencing the problem in having to replace the unit out of warranty, despite seeing Tesla’s mistake as the source of the problem instead of a normal issue that occurs over time.

Last year, the National Highway Traffic Safety Administration (NHTSA) said that it has launched an official investigation into the matter.

A few months later, Tesla finally officially acknowledged the eMMC failure with its touchscreen and offered an extended warranty.

The move wasn’t welcomed by all Tesla owners as many thought that it didn’t go far enough in addressing what is seen by many as an important defect.

The entire issue has been quite a fiasco so far.

Considering there are many important functions that can only be accessed through the touchscreen/MCU in Tesla vehicles, NHTSA was looking into the matter as a potential safety issue, and despite Tesla’s warranty change, the agency was still considering a recall.

Official data released by Tesla to NTHSA showed that the failure rate of the MCU for Model S and Model X was as high as 30% in certain build months.

Furthermore, we have received may reports from owners who have had difficulties making Tesla actually change or repair their MCUs under the new warranty since the announcement – leading for many owners to call for a recall.

NHTSA asks for a recall

NHTSA has now officially asked Tesla to recall 158,000 Model S and Model X vehicles over the issue – a rare move as automakers will often opted to issue voluntary recalls.

Now, Tesla has two weeks to issue a response or accept the recall.

The agency confirmed that it met with Tesla over the issue and evaluated all the information, but it determined that losing capacity of the MCU is a safety issue since a lot of important functions go through the system like windshield defogging, audible chimes, and even turn signals can be impacted.

NHTSA notes that other automakers have issued recalls for similar loss of functions.

The agency noted that the updates that Tesla released to mitigate the issue are “procedurally and substantively insufficient” and that the automaker even confirmed that all the MCUs will eventually fail.

Op het aandeel $ 854 heeft het geen invloed.
