Let's summarize, PM motors are blowing up, everyone's 12V is dying, all cars are riddled with bugs, and Tesla never considered profit margins in their cars on the base models. The sky has fallen multiple times and in the meantime Nissan is rolling out high-range bug free cars in mass quantity. If you drive a Tesla within 50 feet of Lorenfb the car will self destruct. So be careful....
That was hilarious.
The continuous thing that people overlook is that when problems are identified (that they didn't account for or show up on S or X platforms) that they can put out Over-The-Air/OTA updates to tweak the software or revamp it. They can do this in moderation to monitor it or in mass.
OTA updates are a SUBSTANTIAL thing that other manufacturers do NOT have and then they take considerably longer to put out cars as they try to make as-perfect-as-possible interfaces and component interactions.
Tesla Model 3 updates
You are aware that not all vehicle problems can be resolved by OTA updates, i.e. there're ECUs which can only be re-flashed (updated)
by having the vehicle at the service department using the vehicle's diagnostic tool, e.g. for Nissan - the Consult tool. And in many cases,
the ECU can't easily be re-flashed by the OEM's diagnostic tool, but must be sent back or replaced by the ECU's OEM, e.g. an ABS ECU,
a suspension controller, or the motor controller. A good example is the present Nissan Leaf problem with the TCU module causing
problematic issues with the 12V battery, i.e. most likely the TCU in all likelihood must be replaced. So OTA updates are useful for tweaking
UI issues and major mods to the AP system, but is very limited when it comes to major problematic running/driveability issues.
Remember, Tesla vehicles as is the case for all automotive vehicles, in addition to the main system processor (for UI & AP), have
distributed processors (ECUs) that function independently based on each ECU's firmware. Most vehicles today may easily have 10-20
distributed processors connected via a network (multiple CAN systems), which aren't easily updated by an OTA when issues arise.
